Abstract

A mattress with multiple-layer structure comprises a multiple-layer structure which are stacked onto each other and combined together by the eco-friendly adhesive. In the stacked sequence from bottom to top, the first-layer cushion is a plate of foamed cross-linked polyethylene (XPE) or foamed cross-linked polypropylene (XPP), the second-layer cushion is the synthetic foam, EVA foam or high-density PU foam, the third-layer cushion is a porous elastic plastic filament cushion with highly ventilating, supporting and cushioning effect, the fourth-layer cushion is the PU foam, the fifth-layer cushion is a gel cushion on which the through holes are formed, and the sixth-layer cushion is a soft foam which is a memory foam or an ordinary PU foam or latex foam. The densities of the first, the second, the fourth and the sixth-layer cushions are gradually decreased and are different from each other. The support force are gradually increased from top to bottom to provide the sufficient support force and have better shock absorption and pressure distribution properties without rigid bottom-touching feeling; additionally, there will be no spring resilient force imposed on the user. The gel may absorb the shock and distribute the pressure combining with the cushioning characteristic of the porous elastic plastic filaments, which may achieve the combined effect not provided by ordinary foam, pure memory foam or independent- spring bed. Because the third-layer cushion structure composed of porous elastic plastic filament cushion has the air chambers communicated with each other for air flow and temperature adjustment, the overall mattress may have improved ventilation without sultry feeling.

The mattress of the multi-layer structure provided by the invention is compared with other conventional mattresses, and the progress is as follows:

1. The invention adopts Cross-Linked Polyethylene (XPE) or Cross-Linked Polypropylene (XPP) sheet is a closed cell (independent) bubble structure. The crosslinked molecular structure makes the crosslinked XPP or crosslinked XPE sheet hard and stiff and strong. The toughness is higher than other foaming materials. If it is used as the bottom layer of the first layer of mat, it has light weight, good strength, is not easy to deform and does not grow mold and does not absorb water, moisture, and heat insulation (with low thermal conductivity). Rate), good stability support, no rebound force, good chemical corrosion resistance, good stress resistance and tear resistance, no harmful gas release during combustion, is a material that conforms to the concept of environmental protection, and so on. Cross-linked XPE or cross-linked XPP sheets have better support stiffness than other plastic sheets, and they are not as bulky as the iron frame at the bottom of the spring mattress, nor are they soft like ordinary foam, so the bottom mattress is more The foam pad is more convenient for the user to move.

2. The invention adopts a gel pad as a fifth layer pad. When the pressure of the user lying on the bed against the weight of the body or the impact vibration force generated when the body is turned over, the gel pad is quickly absorbed and evenly transmitted to the gel pad. Each side of the face makes the mattress have a good shock-absorbing effect, and the mattress remains stable and silent when getting up or flipping, and does not affect the person on the pillow.

3. The invention adopts a porous elastic plastic wire mat as a third layer pad, because it has irregular plurality of connected pores by the elasticity of the elastic plastic wire and a large gap between the wire and the wire, so that the first The three-layer pad has the advantages of light weight, breathability, moisture release, softness and support, and cushioning and shock absorption. In addition to reducing the overall weight of the bed, the heat can be discharged from the bed in the middle part, so that the mattress is kept dry. The temperature avoids dust mites and mold growth, and is disposed under the gel pad. When the impact vibration force is too large, the gel pad can not absorb the shock and pressure, and the impact force transmits the porous elastic plastic wire pad. The porous elastic plastic wire mat supports the shock absorption characteristics, and the impact vibration force is completely absorbed and uniformly dispersed. The pressure is like a damping effect, and the user is like a mattress lying under no pressure. Therefore, the combination of the gel pad and the porous elastic plastic wire pad makes the shock absorption and pressure more effective, which is not seen in Among the various known spring mattresses or foam mattresses or other mattresses, it is one of the important technical features of the present invention.

4. The present invention gradually reduces the density of the second layer mat and the fourth layer mat and the sixth layer mat, so that the second layer mat and the fourth layer mat and the sixth layer mat have a progressive buffering effect when absorbing pressure. Finally, the pressure disappears into the invisible, so that the user does not have the feeling of sudden sinking, which is an effect that the memory foam mattress cannot achieve. The mattress of the invention has the effect of shock-absorbing damping, and is more stable to achieve the buffering effect. .

5. The invention is applied through the combination of the six-layer pad structure, so that the use of lying on the bed surface does not feel a rebound force, and the body is not uncomfortable, which is impossible for the spring mattress, and The gel pad is placed above the porous elastic plastic wire mat, so that the force of the user's pressing force is absorbed by the gel, and the remaining pressure that has not been absorbed is further passed through the porous elastic plastic wire mat and XPE or XPP. The panel's re-shock cushioning allows the user's body weight to slowly drop invisibly like a damper, not only does it have a bottoming feeling; it also has no rebound force, which is also a general foam mattress or a memory foam mattress or latex. The effect that the mattress can't achieve. Therefore, the present invention mainly improves the shortcomings of the current spring mattress and the foam mattress, and further develops a kind of excellent support, enhanced shock absorption and buffering effect, heat dissipation and the like. An innovative mattress that features a single body.
