Abstract
A pressure-distributing foam structure for use in a seat application may he produced from a foam mixture comprising an ethylene oxide capped diol in a range of about 37 to about 96% weight. The foam structure may have a hardness at 25% deflection that varies within +/−150% in a temperature range of −20° C. to 50° C. The foam structure has a hysteresis loss that varies within +/−40% in the temperature range of −20° C. to 50° C. The pressure-distributing foam structure may be used in a seat component, such as a seat back, a seat cushion, and/or a head rest. A method of making the pressure-distributing foam structure may comprise mixing the ethylene oxide capped diol with at least one of a copolymer polyol and a base polyol.
