Abstract (en)
Apparatuses for supporting at least a portion of the body thereon, including a mattress or a mattress topper, include a polyurethane gel layer (50, 100) overlying at least one support layers in a foam material (60). The gel layer (50, 100) has a hardness of 4. 5 kPa ± 1.5 kPa and a hysteresis of about 40% ± 10%. The gel layer (50, 100) faces a user, such that the gel layer confers objective and subjective comfort at the same time; moreover, a method for preparing a support apparatus including a gel layer (50, 100) and a second layer (62), such as a foam layer (60) is provided. In particular, the invention provides a method for making a mattress. The method generally includes preparing a gel layer (50, 100) and affixing the gel layer to a second layer (62). In certain embodiments where a foam layer (60) is used as the second layer (62), the foam layer (60) may have a surface having a cavity formed therein for receiving the gel layer (50, 100).
