Description

L'invention concerne les matelas de laine.The invention relates to wool mattresses.

Domaine technique de l'inventionTechnical field of the invention

Les avantages de la laine comme matériau de garnissage pour les matelas sont bien connus. Sa faible résistance thermique procure à l'utilisateur une sensation de fraîcheur qui, combinée à sa capacité à absorber la vapeur d'eau produite par le corps, assure un excellent confort de couchage.The advantages of wool as a filling material for mattresses are well known. Its low thermal resistance provides the user with a feeling of freshness which, combined with its ability to absorb water vapor produced by the body, ensures excellent sleeping comfort.

Il s'agit en outre d'une matière entièrement naturelle, disponible en abondance, durable et peu coûteuse. De plus, les matelas de laine peuvent être rénovés plusieurs fois en conservant le garnissage d'origine, après nettoyage, recardage, remise à neuf et changement de la toile extérieure.It is also an entirely natural material, available in abundance, durable and inexpensive. In addition, wool mattresses can be renovated several times while retaining the original filling, after cleaning, recarding, refurbishing and changing the outer fabric.

La laine présente toutefois des inconvénients qui lui font de plus en plus souvent préférer la mousse ou le latex comme matériau de garnissage pour des matelas.However, wool has drawbacks that make it more and more often prefer foam or latex as filling material for mattresses.

En premier lieu, les matelas de laine se déforment au fil du temps et doivent être retournés régulièrement, ce que souvent les utilisateurs ne font pas car un tel matelas est lourd. En tout état de cause, la laine finit à la longue par se tasser et se creuser, et n'offre pas un aussi bon maintien et une aussi bonne distribution des pressions du corps qu'un matelas garni de mousse, de latex et/ou avec des ressorts ensachés.First, wool mattresses deform over time and have to be turned over regularly, which users often do not do because such a mattress is heavy. In any case, wool ends up settling and hollowing out over time, and does not offer as good support and as good a distribution of pressure on the body as a mattress filled with foam, latex and/or with pocket springs.

Un autre inconvénient du matelas de laine tient au fait que le confort d'un matelas en laine est souvent déterminé par le type de sommier avec lequel il est utilisé. Le matelas offrant par lui-même peu de maintien, il est vivement conseillé d'utiliser un matelas en laine avec un sommier à lattes souples, qui offre un maintien différent en fonction des parties/poids du corps. Le rôle du sommier est donc très important pour un matelas en laine traditionnel.Another disadvantage of the wool mattress is that the comfort of a wool mattress is often determined by the type of box spring with which it is used. The mattress itself offering little support, it is strongly recommended to use a wool mattress with a soft slatted base, which offers different support depending on the parts/weight of the body. The role of the box spring is therefore very important for a traditional wool mattress.

Un autre inconvénient encore du matelas de laine est qu'il ne peut être réalisé que par des techniques artisanales, donc coûteuses.Yet another disadvantage of the wool mattress is that it can only be made by artisanal techniques, which are therefore costly.

En effet, il n'a jusqu'à présent pas été possible d'industrialiser de façon rationnelle la production des matelas de laine, à la différence des matelas de mousse ou de latex dont la fabrication peut être assurée de façon largement automatisée et en grande série, permettant d'offrir au consommateur des produits relativement confortables à des prix bien inférieurs.Indeed, it has not until now been possible to rationally industrialize the production of wool mattresses, unlike foam or latex mattresses, the manufacture of which can be ensured in a largely automated and large-scale manner. series, making it possible to offer the consumer relatively comfortable products at much lower prices.

L'invention a pour but de pallier ces inconvénients, en proposant une nouvelle structure de matelas essentiellement à base de laine :

  • dont la production soit industrialisable et permette d'abaisser significativement les coûts de fabrication ;
  • qui procure un confort de couchage élevé, en conservant les avantages du matelas de laine (fraîcheur, respirabilité) mais avec un bien meilleur maintien que les matelas de laine actuels - et ceci indépendamment du maintien offert par le sommier ; et
  • qui puisse être aisément rénové, d'une façon plus simple (et donc moins coûteuse) que par les techniques artisanales actuelles, voire même qui puisse être rénové sur place chez l'utilisateur, donc sans enlèvement du matelas et sans transport en atelier.
The object of the invention is to overcome these drawbacks, by proposing a new mattress structure essentially based on wool:
  • whose production can be industrialized and can significantly reduce manufacturing costs;
  • which provides high sleeping comfort, while retaining the advantages of the wool mattress (freshness, breathability) but with much better support than current wool mattresses - and this independently of the support offered by the bed base; and
  • which can be easily renovated, in a simpler way (and therefore less expensive) than by current artisanal techniques, or even which can be renovated on site at the user's, therefore without removal of the mattress and without transport to the workshop.

Il s'agit en outre, selon l'invention, de privilégier une approche écologique dans la conception d'un tel matelas, qui non seulement utilise un matériau naturel abondant et disponible à faible coût écologique - la laine -, mais qui offre en outre un produit facilement à réparer et à rénover à plusieurs reprises, donc avec une très longue durée de vie potentielle et, de fait, un gain écologique considérable.It is also, according to the invention, to favor an ecological approach in the design of such a mattress, which not only uses an abundant natural material available at low ecological cost - wool -, but which also offers a product that is easy to repair and renovate several times, therefore with a very long potential lifespan and, in fact, a considerable ecological gain.

On verra également que les matériaux d'origines différentes utilisés pour la réalisation du matelas selon l'invention ne sont pas mélangés, ce qui permet en fin de vie du produit de recycler séparément ces matériaux et de les insérer aisément dans leurs processus respectifs de recyclage ou de revalorisation, respectant ainsi au mieux les principes d'une "économie circulaire".It will also be seen that the materials of different origins used for the production of the mattress according to the invention are not mixed, which makes it possible, at the end of the life of the product, to recycle these materials separately and to easily insert them into their respective recycling processes. or upgrading, thus respecting the principles of a "circular economy" as much as possible.

État de la technique antérieureState of the prior art

L'état de la technique n'a jusqu'à présent pas permis d'atteindre ces buts. Ainsi le EP 2 078 477 A1 , après avoir exposé de façon très complète et très détaillée tous les avantages de la laine comme matériau de garnissage pour une "couche de confort" d'un matelas, conclut en proposant d'utiliser pour cette couche de confort, plutôt que de la laine, un matériau de substitution constitué d'une mousse de polyuréthanne dans laquelle sont dispersées les particules d'un polymère superabsorbant à base de polyacrylate ou de polyméthacrylate, pour donner à la mousse une capacité d'absorption et une respirabilité répliquant plus ou moins celles de la laine.The state of the art has hitherto not made it possible to achieve these goals. So the EP 2 078 477 A1 , after having exposed in a very complete and very detailed way all the advantages of wool as a material of filling for a "comfort layer" of a mattress, concludes by proposing to use for this comfort layer, rather than wool, a substitute material consisting of a polyurethane foam in which the particles of a superabsorbent polymer based on polyacrylate or polymethacrylate, to give the foam an absorption capacity and breathability more or less replicating that of wool.

Le US 2017/088990 A1 décrit une structure comprenant un cœur de matelas, assurant le soutien, enfermé dans une enveloppe comprenant sur l'une et/ou sur l'autre de ses deux faces une couche formée d'un sandwich de plusieurs matériaux. Cette couche de surface incorpore, pour le confort, une épaisseur de mousse de haute densité et une ou plusieurs épaisseurs d'autres matériaux, notamment de laine. Un tel matelas offre ainsi le contact agréable de la laine mais, du fait de la faible épaisseur de la couche, la laine ne procure aucune fonction de soutien et ne constitue qu'une part très minoritaire des matériaux utilisés pour la réalisation du matelas.the US 2017/088990 A1 describes a structure comprising a mattress core, providing support, enclosed in an envelope comprising on one and/or the other of its two faces a layer formed of a sandwich of several materials. This surface layer incorporates, for comfort, a layer of high-density foam and one or more layers of other materials, in particular wool. Such a mattress thus offers the pleasant contact of wool but, due to the low thickness of the layer, the wool does not provide any support function and constitutes only a very minor part of the materials used for the production of the mattress.

Le EP 0 806 166 A2 propose une structure de matelas composite avec un empilement de plusieurs couches de natures différentes, par exemple quatre couches avec, côté sommier, une couche avec un garnissage de fibres (par exemple de fibres de coco) sur laquelle est posée une première couche de latex, elle-même supportant un matelas à ressorts, et enfin une seconde couche de latex, côté couchage. Ces différentes structures indépendantes, qui ne sont pas fixées les unes aux autres, sont réunies dans une même enveloppe commune en tissu, pouvant être ouverte sur trois ou quatre côtés. Le matelas obtenu procure sans doute un excellent confort, mais sa structure multicomposite est complexe à réaliser, donc coûteuse. De plus, la structure n'est pas réversible (le matelas, lourd, n'ayant d'ailleurs pas vocation à être retourné car n'étant pas symétrique) et, enfin, la laine n'est envisagée que de façon très subsidiaire, et sans chercher à bénéficier des avantages bien connus de cette matière.the EP 0 806 166 A2 proposes a composite mattress structure with a stack of several layers of different natures, for example four layers with, on the bed base side, a layer with a filling of fibers (for example coconut fibers) on which is placed a first layer of latex, itself supporting a spring mattress, and finally a second layer of latex, sleeping side. These different independent structures, which are not fixed to each other, are united in the same common fabric envelope, which can be opened on three or four sides. The mattress obtained undoubtedly provides excellent comfort, but its multicomposite structure is complex to produce, and therefore expensive. In addition, the structure is not reversible (the mattress, heavy, not intended to be turned over because it is not symmetrical) and, finally, wool is only considered in a very subsidiary way, and without seeking to benefit from the well-known advantages of this material.

Description détaillée de modes de réalisation de l'inventionDetailed Description of Embodiments of the Invention

Comme illustré sur les figures 1 et 2, l'ensemble de matelas selon l'invention comporte, essentiellement, un matelas d'accueil 10 reposant sur un matelas socle 20. Les deux matelas d'accueil 10 et socle 20 sont indépendants et séparables, le matelas d'accueil 10 reposant librement sur le matelas socle 20. Avantageusement, les matelas 10 et/ou 20 sont des matelas réversibles.As illustrated on the figures 1 and 2 , the mattress assembly according to the invention essentially comprises a host mattress 10 resting on a base mattress 20. The two host mattresses 10 and base 20 are independent and separable, the host mattress 10 resting freely on the base mattress 20. Advantageously, the mattresses 10 and/or 20 are reversible mattresses.

Cet ensemble de deux matelas 10, 20 est normalement destiné à reposer sur un sommier 30 (qui ne fait pas partie de l'invention). De plus, une alèse 40 recouvre avantageusement la face supérieure du matelas d'accueil 10, en contact avec l'utilisateur, de manière à protéger le matelas à cet endroit.This set of two mattresses 10, 20 is normally intended to rest on a bed base 30 (which is not part of the invention). In addition, a mattress protector 40 advantageously covers the upper face of the receiving mattress 10, in contact with the user, so as to protect the mattress at this location.

De façon caractéristique de l'invention, le matelas d'accueil 10 est un matelas comprenant un garnissage en laine 11, tandis que le matelas socle 20 est un matelas comprenant un garnissage en mousse 21.Characteristically of the invention, the host mattress 10 is a mattress comprising a wool filling 11, while the base mattress 20 is a mattress comprising a foam filling 21.

Le garnissage en laine 11 du matelas d'accueil 10 est, également de façon caractéristique de l'invention, formé d'un empilement de couches de laine en nappe superposées, dans l'exemple illustré cinq couches 11a ... 11e de laine en nappe.The wool filling 11 of the reception mattress 10 is, also characteristically of the invention, formed of a stack of layers of superimposed sheet wool, in the example shown five layers 11a ... 11e of sheet wool.

Une composition typique du garnissage 10 est, par exemple et de façon non limitative, un empilement de quatre à cinq nappes de laine de 12 cm d'épaisseur chacune. La laine utilisée peut être par exemple une laine nappée (aiguilletée) de 1,5 kg/m2 pour 12 cm d'épaisseur.A typical composition of the packing 10 is, for example and without limitation, a stack of four to five layers of wool 12 cm thick each. The wool used may for example be a coated (needled) wool of 1.5 kg/m 2 for 12 cm in thickness.

Le garnissage en laine 11 est enfermé dans une enveloppe 12, par exemple une enveloppe en forme de housse fermée sur trois côtés par une fermeture à glissière 13. La housse de l'enveloppe 12 peut être notamment une housse en lin, pour le confort (régulation thermique) et son caractère écologique.The wool filling 11 is enclosed in an envelope 12, for example an envelope in the form of a cover closed on three sides by a zipper 13. The cover of the envelope 12 may in particular be a linen cover, for comfort ( thermal regulation) and its ecological character.

Avantageusement, des capitons 14 sont réalisés sur l'étendue du matelas, le nombre des capitons étant fonction de la fermeté souhaitée pour le matelas. Avantageusement, ces capitons peuvent être de couleurs différentes sur chacun des deux côtés du matelas d'accueil 10, afin que l'utilisateur puisse se souvenir s'il a retourné ou non le matelas. Des poignées latérales 16 peuvent être prévues pour faciliter cette opération de retournement du matelas d'accueil en laine.Advantageously, dimples 14 are made over the extent of the mattress, the number of dimples being a function of the firmness desired for the mattress. Advantageously, these dimples can be of different colors on each of the two sides of the receiving mattress 10, so that the user can remember whether or not he has turned the mattress over. Side handles 16 can be provided to facilitate this operation of turning over the wool mattress.

Dans l'exemple indiqué plus haut d'un empilement de quatre à cinq nappes de 12 cm chacune, l'épaisseur totale du matelas d'accueil 10 sera de l'ordre de 15 cm après capitonnage, compte tenu de la compression exercée sur les nappes de laine par le capitonnage.In the example indicated above of a stack of four to five layers of 12 cm each, the total thickness of the receiving mattress 10 will be of the order of 15 cm after padding, taking into account the compression exerted on the woolen tablecloths by the padding.

On notera toutefois que, à la différence d'un matelas traditionnel réalisé avec un garnissage de flocons de laine, pour le matelas d'accueil de l'invention un capitonnage n'est pas indispensable, car le matériau aiguilleté de la laine en nappe ne se déplacera pas à l'intérieur de l'enveloppe 12 - contrairement à un garnissage traditionnel de laine en flocons.It will be noted however that, unlike a traditional mattress made with a filling of wool flakes, for the reception mattress of the invention a padding is not essential, because the needled material of the wool in sheet does not will not move inside the casing 12 - unlike a traditional woolen flake filling.

La fermeté du matelas d'accueil 10 peut être éventuellement ajustée par zones en utilisant par exemple de la laine en flocons à quelques endroits spécifiques du matelas (tels que les épaules et les hanches). Il est également possible d'interposer entre deux couches de laine en nappe une couche intercalaire de laine en flocons.The firmness of the receiving mattress 10 can optionally be adjusted by zones by using, for example, wool flakes at a few specific places of the mattress (such as the shoulders and the hips). It is also possible to interpose between two layers of wool in sheet form an intermediate layer of wool in flakes.

La fermeté du matelas d'accueil peut être également ajustée en insérant une couche de laine nappée plus ferme ou plus dense sur tout ou partie du matelas et/ou dans certaines régions spécifiques telles que les épaules et les hanches.The firmness of the reception mattress can also be adjusted by inserting a firmer or denser layer of woolen cloth over all or part of of the mattress and/or in certain specific regions such as the shoulders and the hips.

Le matelas socle 20, quant à lui, comprend un garnissage en mousse 21 enfermé dans une enveloppe 22, par exemple une housse en polyester. La mousse utilisée est, par exemple et de façon non limitative, une mousse de 80 kg/m3 en plaque de 8 cm d'épaisseur (il est également possible d'utiliser une mousse moins dense mais plus épaisse).The base mattress 20, for its part, comprises a foam filling 21 enclosed in an envelope 22, for example a polyester cover. The foam used is, for example and without limitation, an 80 kg/m 3 foam in a plate 8 cm thick (it is also possible to use a less dense but thicker foam).

Le choix d'une mousse relativement dense, de préférence supérieure à 35 kg/m3, permet d'obtenir un matelas socle 20 très ferme qui assure par lui-même un soutien ferme et durable, de sorte que le sommier 30 qui supportera le matelas socle 20 n'aura pas, en lui-même, de rôle de soutien. On évite ainsi les sommiers coûteux à lattes ou à ressorts, qui sont nécessaires dans le cas d'un matelas de laine traditionnel (matelas de laine en flocons où le matelas est directement posé sur le sommier). Le matériau utilisé pour la mousse du garnissage 21 est avantageusement une mousse de polyuréthanne flexible issue du recyclage, c'est-à-dire une mousse composite obtenue à partir de chutes et de flocons de mousse triés et mélangés à un liant. On connaît diverses techniques de recyclage des mousses, telles que rebound foam ou fibre bonded foam, donnant des blocs de mousse en forme de plaques ou rouleaux convenant parfaitement à une utilisation dans le cadre de l'invention pour la réalisation du matelas socle 20 supportant le matelas d'accueil en laine 10.The choice of a relatively dense foam, preferably greater than 35 kg/m 3 , makes it possible to obtain a very firm base mattress 20 which provides by itself firm and lasting support, so that the bed base 30 which will support the mattress base 20 will not, in itself, support role. This avoids expensive slatted or spring bases, which are necessary in the case of a traditional wool mattress (wool flake mattress where the mattress is placed directly on the bed base). The material used for the foam of the packing 21 is advantageously a flexible polyurethane foam from recycling, that is to say a composite foam obtained from foam scraps and flakes sorted and mixed with a binder. Various foam recycling techniques are known, such as rebound foam or fiber bonded foam , giving foam blocks in the form of plates or rolls which are perfectly suitable for use in the context of the invention for the production of the base mattress 20 supporting the wool welcome mattress 10.

La face 23 du matelas socle 20 qui sera en contact avec la face inférieure du matelas d'accueil 10 est avantageusement munie d'un tissu antidérapant afin de maximiser l'adhérence et éviter que le matelas d'accueil 10 ne glisse sur le matelas socle 20 sur lequel il est posé. Si l'on souhaite pouvoir retourner le matelas socle 20, chacune des deux faces du matelas sera équipée d'un tel tissu antidérapant.The face 23 of the base mattress 20 which will be in contact with the underside of the reception mattress 10 is advantageously provided with a non-slip fabric in order to maximize adhesion and prevent the reception mattress 10 from slipping on the base mattress. 20 on which it is placed. If it is desired to be able to turn over the base mattress 20, each of the two faces of the mattress will be equipped with such a non-slip fabric.

Avantageusement, les deux matelas sont réunis par des pattes 24 de centrage et de maintien fixées aux quatre coins de l'enveloppe 22 du matelas socle 20, avantageusement des pattes textiles réversibles si l'on souhaite pouvoir retourner le matelas socle 20, de manière que les pattes 24 puissent se présenter toujours dirigées vers le haut, après que le matelas a été retourné. Ces pattes peuvent en outre comprendre une boutonnière 25 apte à coopérer avec un bouton respectif 15 du matelas d'accueil 10 (ou vice versa la patte 24 peut comprendre un bouton apte à coopérer avec une boutonnière d'une pièce textile solidaire du matelas d'accueil 10).Advantageously, the two mattresses are joined by centering and holding tabs 24 fixed to the four corners of the casing 22 of the base mattress 20, advantageously reversible textile tabs if it is desired to be able to turn the base mattress 20 over, so that the tabs 24 can always be directed upwards, after the mattress has been turned over. These tabs may further comprise a buttonhole 25 capable of cooperating with a respective button 15 of the receiving mattress 10 (or vice versa the tab 24 may comprise a button capable of cooperating with a buttonhole of a piece of textile integral with the receiving mattress 10).

Le bouton 15 du matelas d'accueil 10 peut être en outre passé dans une boutonnière 41 solidaire de l'alèse 40 à chacun des coins de celle-ci, ce qui permet de maintenir l'alèse bien tendue sur le matelas d'accueil en laine 10.The button 15 of the reception mattress 10 can also be passed through a buttonhole 41 secured to the mattress pad 40 at each of the corners of the latter, which makes it possible to keep the mattress taut on the reception mattress in wool 10.

On notera que, grâce à ce système d'attaches réversibles, les matelas sont tous deux retournables indépendamment dans les deux dimensions (dessus/dessous et tête/pieds), ce qui permet de leur conserver un maintien à peu près uniforme et de prolonger la durée de vie de l'ensemble.It should be noted that, thanks to this system of reversible attachments, the mattresses can both be turned over independently in the two dimensions (top/bottom and head/feet), which allows them to maintain a more or less uniform support and to prolong the lifetime of the whole.

On va maintenant décrire, en référence à la Figure 3, un exemple de processus de fabrication de l'ensemble de matelas que l'on vient de décrire.We will now describe, with reference to the Figure 3 , an example of the manufacturing process of the mattress assembly just described.

Pour la fabrication du matelas d'accueil 10, une nappe de laine en rouleau est découpée de manière à obtenir (étape A) des pièces 11a, ... 11d dont les dimensions en longueur et en largeur correspondent à la longueur et à la largeur du matelas d'accueil à réaliser. Ces pièces de laine en nappe sont empilées (étape B) de manière à constituer le garnissage 11 en laine. Ce garnissage 11 est placé (étape C) dans l'enveloppe 12, qui est une housse pré-cousue munie d'une fermeture à glissière sur trois ou quatre de ses côtés. Une fois cette housse refermée (étape D), le matelas d'accueil 10 obtenu fait avantageusement (mais non nécessairement) l'objet d'un capitonnage (étape E), le nombre de capitons 14 à poser dépendant de la fermeté souhaitée pour le matelas. Le matelas d'accueil 10 ainsi réalisé peut être roulé (étape F), ce conditionnement étant rendu possible par l'épaisseur plus réduite et le travail en nappe, ce qui ne serait pas possible avec un matelas traditionnel à base de flocons de laine, beaucoup plus épais et extrêmement difficile à enrouler.For the manufacture of the reception mattress 10, a sheet of wool in a roll is cut so as to obtain (step A) parts 11a, ... 11d whose length and width dimensions correspond to the length and width of the reception mattress to be made. These pieces of fleece wool are stacked (step B) so as to form the packing 11 of wool. This filling 11 is placed (step C) in the envelope 12, which is a pre-sewn cover provided with a zipper on three or four of its sides. Once this cover has been closed (step D), the reception mattress 10 obtained is advantageously (but not necessarily) padded (step E), the number of pads 14 to be placed depending on the firmness desired for the mattress. The reception mattress 10 thus produced can be rolled (step F), this packaging being made possible by the reduced thickness and the work in a sheet, which would not be possible with a traditional mattress based on wool flakes, much thicker and extremely difficult to roll up.

Pour le matelas socle, un bloc de mousse 21 est découpé aux dimensions de longueur, largeur et épaisseur souhaitées, et placé (étape C') dans son enveloppe 22, ici encore avantageusement réalisée sous forme d'une housse pré-cousue munie d'une fermeture à glissière sur trois ou quatre de ses côtés. Après fermeture (étape D'), le matelas socle 20 est avantageusement roulé (étape F'), ce qui permet d'obtenir en fin de processus deux rouleaux distincts 10, 20 aisés à conditionner, manipuler et transporter (étape G).For the base mattress, a foam block 21 is cut to the desired length, width and thickness dimensions, and placed (step C′) in its envelope 22, here again advantageously made in the form of a pre-sewn cover with zipper on three or four sides. After closing (step D′), the base mattress 20 is advantageously rolled up (step F′), which makes it possible to obtain, at the end of the process, two separate rolls 10, 20 that are easy to package, handle and transport (step G).

La structure de matelas composite selon l'invention se prête également très bien à la rénovation. En particulier, la partie la plus facilement abîmée, à savoir le matelas d'accueil en laine 10, est non seulement facile à retourner pour réduire les dégradations, mais peut être séparée du matelas socle 20 pour être amenée chez un tapissier, ou même recardée à domicile. À cet effet, il suffit après avoir coupé les capitons de déhousser le garnissage en laine 11 et le carder. Ce cardage est facilité du fait de la conformation de la laine en nappes et non en flocons. Le cardage pourra être de fait réalisé aisément avec des pointes, selon des techniques en elles-mêmes traditionnelles. Les nappes de laine recardées sont ensuite replacées dans la housse, puis recapitonnées.The composite mattress structure according to the invention also lends itself very well to renovation. In particular, the most easily damaged part, namely the wool mattress 10, is not only easy to turn over to reduce damage, but can be separated from the base mattress 20 to be taken to an upholsterer, or even recarded home. To this end, it suffices after having cut the padding to remove the woolen filling 11 and card it. This carding is facilitated by the conformation of the wool in layers and not in flakes. The carding can in fact be carried out easily with points, according to techniques which are traditional in themselves. The recarded wool layers are then replaced in the cover, then re-padded.

Si la housse d'origine est tachée, elle pourra être aisément lavée ou remplacée par une housse neuve (et de même pour le matelas socle 20 si nécessaire). On notera que, à la différence des techniques traditionnelles de rénovation des matelas de laine, il n'est pas nécessaire de découdre ni de changer l'enveloppe, dans la mesure où le garnissage de nappes de laine est simplement logé dans une housse refermable.If the original cover is stained, it can easily be washed or replaced with a new cover (and the same for the base mattress 20 if necessary). It should be noted that, unlike traditional techniques for renovating wool mattresses, it is not necessary to unsew or change the envelope, insofar as the filling of wool sheets is simply housed in a resealable cover.

On obtient ainsi un produit réparable, ce qui multiplie sa durée de vie : la partie en laine peut être facilement recardée tous les cinq à dix ans, tandis que le socle en mousse ne subit pas ou peu de dommages dans le temps.A repairable product is thus obtained, which multiplies its lifespan: the wool part can be easily re-carded every five to ten years, while the foam base suffers little or no damage over time.

On notera que la réparabilité procure un gain écologique considérable à ce type de produit, qui aujourd'hui n'est pas réparable.It should be noted that repairability provides a considerable ecological gain for this type of product, which cannot be repaired today.

De plus, en fin de vie, les matériaux d'origines différentes (laine/mousse) peuvent être aisément séparés, ce qui permet de les valoriser plus facilement. Aucune matière n'étant mélangée, il sera facile de les réinsérer dans des processus spécifiques respectifs de recyclage ou de revalorisation.In addition, at the end of their life, materials of different origins (wool/foam) can be easily separated, which makes it easier to recycle them. As no material is mixed, it will be easy to reintegrate them into respective specific processes of recycling or revaluation.
