So I’ve never had a foam mattress and have always  stayed away from them. However, I thought okay its time I give this a shot. Understand, I typically sleep on firm mattresses and my air mattress was maxed at 100 but my wife likes it softer. So I chose the medium 10” thick mattress hoping it would have the support I was looking for and the softness she loved. Skeptical at first.... but oh boy, that first night..... I haven’t slept that good in years. Instantly we both feel in love with this bed and we couldn’t be more happy with it. Could I have gotten the 8” firm? Yes, but honestly the medium is working out just fine. Oh and I haven’t experienced any overheating with this either. So give it a try, like me, I’m sure you’ll be happy you did.
