Also, the present invention provides a novel mattress with the ability to allow a free passage of air in its upper layer that limits the accumulation of moisture and at the same time serves as a cushioning mechanism that allows the upper layer to adapt to the contours of the body of the body. user.
  • the mattress of the present invention is formed by four consecutive layers which are: a base layer (1), an intermediate support layer (2), a top support layer (3) and a charge diffusion layer (4). These layers, as well as their construction and function will be described in more detail below.
  • the base layer (1) is located in the lower part of the multilayer mattress arrangement of the present invention and is formed by a polymeric foam material having a density between 58 and 62 kg / m3 and a high resilience. Said base layer (1) has a thickness between 5 to 30 cm, said thickness being preferably between 10 and 15 cm.
  • This layer provides structural rigidity to the mattress and prevents it from deforming; likewise, in case of folding the mattress for example during its transport, this base layer (1) returns the assembly to its resting state, so that the mattress maintains its shape independently of the substrate where it is placed. Also, in case the mattress is rolled to facilitate its transport, this layer allows the mattress to be returned to its fully extended state since it maintains a state memory in its internal cells that allows this layer to return to its original state.
  • the intermediate support layer (2) is attached directly to the base layer (1) by means of an adhesive or by thermal fusion; said layer is of a polymeric foam of density of between 30 to 34 Kg / m3 and a thickness of between 1 to 10 cm, preferably between 4 and 8 cm that serves as a central load element, distributing along all its surface any force received from the upper support layer (3) without deforming because it is a memory layer and also prevents the transmission of forces towards the base layer (1) preventing the latter from being deformed if an excessive weight is applied.
  • the upper support layer (3) is made of a polymeric foam with gel spheres, preferably of polyurethane foam with gel spheres, with a density of between 26 to 30 Kg / m3 and has a thickness of between 1 and 10 cm , preferably between 2 and 6 cm. This is located on the intermediate support layer (2).
  • Said layer fulfills the function of adapting to the contours of the user returning to its original state once it rises and prevents the transmission of movement to other regions of the mattress. Additionally, this layer conforms to the contours of the user selectively compressing only those sites that receive the pressure of an object placed on it, without transmitting lateral forces.
  • the upper support layer (3) has a series of cylindrical cavities distributed throughout its entire surface. These cavities serve as flow paths for air and furthermore prevent the transmission of movement along the surface of the upper support layer (3). Likewise, said cavities allow the upper support layer (3) to conform better to the contours of the user's body in order to provide better support to his column.
  • the load diffusion layer (4) in a preferred embodiment of the invention, completely covers the other three layers of the mattress and is hypoallergenic so it prevents the accumulation of mites and other allergens on its surface.
  • Said load diffusion layer (4) in the preferred embodiment of the invention comprises a lower base (a) having a non-skid pattern of siliconized material, which comes into direct contact with the base layer (1); four retaining sides (b), of textile material, which preferably but not limitatively have a height equal to the overall height of the three foam layers of the mattress and; an upper surface (c) formed by a bilayer of textile material having lines with a "V" shaped pattern (d) of aeration cells, with an opening angle of between 100 ° to 106 °, the length being the "V" posts between 13cm to 15cm so that a series of load cells containing a micro-fiber gel filling with a diameter of 8-9.85pm are delimited to the interior of the bilayer.
  • this layer The function of this layer is to prevent the transmission of point charges to the load layer superior at the same time that distributes the weight of the user along its entire surface molding to the user's body contours.
  • the load diffusion layer (4) allows a free flow of air through the aeration cells, so that the moisture that passes through the textile bilayer can be expelled from the filled interior, keeping the mattress cool.
  • the distance between each pattern in the form of "V" can go from 17cm to 19cm, being preferably between 18.3 and 18.7cm.
  • the load diffusion layer (4) has an opening system (e) that runs along its entire perimeter; said system allows to remove the load diffusion layer in order to be able to wash it or exchange it for another one in case of wear.

  • the three internal layers of the mattress are covered by a textile lining (not shown) that keeps the set of internal layers joined together and also serves as a secondary barrier that prevents the passage of liquids inside the mattress, in case of that they cross the load diffusion layer (4).
  • the bilayer of textile material is treated to render it impermeable in order to prevent the passage of spilled liquids towards the layers internal mattresses.
  • the charge diffusion layer (4) comprises only the top surface (c) and a perimeter skirt having a height substantially less than the height of the internal layers of the mattress.
  • Said perimeter skirt has at its free end means for fastening to the internal layers, such as ribbons, sailboat, brooches or an elastic band that compresses its walls in order to mold them to the end surfaces of any of the internal layers of the mattress.
  • the load diffusion layer (4) comprises clamping strips that allow fixing said layer to the inner layers of the sucker so that most of the free surfaces of the sides of the three internal layers is uncovered, allowing a better aeration of the mattress.
