The iComfort Sleep System by Serta, featuring TempActiv Gel Memory Foam. It was one of the first to make affordable high-quality memory foam. Heat build-up during the night can cause uncomfortable and restless sleep. This was a common problem among traditional memory foam. Serta's Cool Action Memory Foam, the predecessor of TempActiv Gel Memory Foam eliminated the issue of heat retention. If you're looking for an affordable memory foam mattress that won't sleep hot, Serta iComfort is an excellent option.
You can also buy iComfort Hybrid mattresses. This selection of mattresses adds a 1025 iComfort Hybrid Support System. This adds an Individually wrapped coil system to provide body contouring for better support. Engineered to be adjustable base friendly, and reduce motion transfer for undisturbed sleep.
