Hello. We got our bed about 7 months ago now. We went from an 8yr old TempurPedic to this. The tempurpedic was quite hot and I am a hot sleeper. This ReST bed does sleep much cooler. Still a little on the warm side, but not bad at all. The bed is very comfortable and it didn’t take long to figure out the settings for both sleepers. We got the 1/2 split king bed. Highly recommend. A+ bed and customer service.
