Kaymed's iKool™ is an original and patented technology that combines memory foam with MicroSupport™ Gel beads for cooler, smarter and more comfortable sleep. iKool™ is up to 12 times more breathable than normal memory foam, because of its open cell foam design and MicroSupport Gel’s heat diffusing properties. It delivers up to twice the support of normal memory foam, as millions of MicroSupport Gel beads cluster in pressure zones for more targeted support. iKool™ provides uniform pressure relief across wider temperature ranges, so you'll sleep comfortably in cold or warm bedrooms.
