摘要:
A body support cushion, e.g., mattress, has multiple foam layers, including a viscoelastic foam layer and a reticulated foam layer, and an outer cover. At least one of the foam layers and the outer cover each includes phase change material having latent heat properties that provide two intervals of dermal cooling.
摘要:
A mattress comprises a sealed outer casing within which is mounted a resilient support formed by a composite foam core. At least an upper portion of the resilient support is formed by a visco-elastic foam. A vent is provided in a side wall of the casing and is covered by a filter which prevents ingress of bacteria into the cover. A flap is mounted on the cover and in use extends down over the vent to prevent the filter being damaged by fluids.
