LESS TOXIC MATTRESS
A mattress and method of constructing the mattress having a reduced toxicity has a cover or an outermost layer including food grade polyethylene. Also, the outer layer of the mattress can also be constructed from a material selected from the same group of materials. Food grade polyethylene films are less toxic materials which reduce adverse human health effects due to the exposure to potentially harmful chemicals used in the mattress construction.
1 . A mattress comprising:
a food grade Low Density Polyethylene (LDPE) and a food grade Linear Low Density Polyethylene (LLDPE) outermost layer;
an outer material in contact with the food grade LDPE and LLDPE outermost layer; and
an inner material in contact with the outer material.
2 . The mattress of claim 1 , wherein the LDPE or LLDPE has a density of 0.85 to 1.00 g/cc; a maximum extractable fraction (expressed as percent by weight of the polymer) in n-hexane at specified temperatures is 5.5% at 50° C.; and a maximum extractable fraction (expressed as percent by weight of the polymer) in xylenes at specified temperatures is 11.3% at 25° C.
3 . The mattress of claim 1 , wherein the LDPE and LLDPE outermost layer is heat fused to the outer material.
4 . The mattress of claim 3 , wherein the outer material comprises cotton, organic cotton, polyester, recycled polyster, polypropylene, polylactic acid, wool, polyurethane, or combinations thereof.
5 . The mattress of claim 1 , wherein the mattress comprises an additional layer composed of a fabric flame barrier which acts as a flame retardant.
6 . The mattress of claim 1 , wherein the inner material comprises a material selected from the group consisting of cotton, organic cotton, LDPE, LLDPE, metal, polyester, recycled polyester, polyurethane, and PLA to provide vibration dampening, insulation, and cushioning.
7 . The mattress of claim 1 , wherein the inner material comprises a support material that maintains a shape of the mattress.
8 . A method to prepare a mattress, comprising the steps of:
(a) forming a food grade LDPE and LLDPE outermost layer;
(b) forming an outer layer contacting the LDPE and LLDPE outermost layer; and
(c) forming an inner material contacting the outer material.
9 . The method of claim 8 , wherein the LDPE or LLDPE has a density of 0.85 to 1.00 g/cc; a maximum extractable fraction (expressed as percent by weight of the polymer) in n-hexane at specified temperatures is 5.5% at 50° C.; and a maximum extractable fraction (expressed as percent by weight of the polymer) in xylenes at specified temperatures is 11.3% at 25° C.
10 . The method of claim 8 , wherein the LDPE and LLDPE outermost layer is heat fused to the outer material.
11 . The method of claim 10 , wherein the outer material comprises organic cotton, cotton, polyester, recycled polyester, polypropylene, PLA, wool, polyurethane, or combinations thereof.
12 . The method of claim 8 , wherein the mattress comprises an additional layer composed of a fabric flame barrier which acts as a flame retardant.
13 . The method of claim 8 , wherein the inner material comprises a material selected from the group consisting of cotton, organic cotton, LDPE, LLDPE, metal, polyester, polyurethane, and PLA to providing vibration dampening, insulation, and cushioning.
14 . The method of claim 8 , wherein the inner material comprises a support material that maintains a shape of the mattress.
15 . The mattress of claim 1 , wherein the mattress outermost layer can be in close proximity to or in contact with a user's skin.
16 . The method of claim 8 , wherein the mattress outermost layer can be in close proximity to or in contact with a user's skin.
17 . The mattress of claim 1 , wherein the mattress is sized to fit a basinet, crib, cradle, or bed.
18 . The method of claim 8 , wherein the mattress is sized to fit a basinet, crib, cradle, or bed.
