Though it is cooler to sleep on which my husband and I both like. It's not as comfortable on my back as advertised. I still wake throughout the night in pain. My husband has to sleep on a boat for 28 days at a time so the 2 weeks he is home the bed feels good enough to him. But we still wake with pinched nerves, that cause numbing and tingling in arms, hands and fingers.
Mattress was a bit costly, but the sleep I get on it is worth every penny. Pro tip: buy your own sheets and pillows. The ones sold on the site are sadly disappointing.
Extremely soft. Not firm at all. Would not buy if you need firmer beds like I do. Waiting to return it . May possibly get a hybrid hopefully I'll have better luck.
