My husband (chiropractor) & I have been desperately in search of a new mattress that would be juuuust right for our needs. He runs very hot & we like a medium firm feel for good spinal support. Let's just say that when it got delivered, hubby went to lay on it & test it, but ended up napping immediately. Love that it stays cool & is so supportive. Thanks TempurPedic for gifting us this mattress in exchange for our honest review!
