My wife and I bought split king proadapt medium mattresses to replace our former tempurpedic king after almost 2 decades. Coupled with the adjustable bed stands, this is the best sleep I've ever had. Complete comfort and deep sleep! A significant investment but well worth it if sleep is important to you and consider that it will be amortized over several years.
This mattress is great. I once woke up with pain in my hips. Not anymore. I "melt" into this mattress. Very comfortable. The hybrid version allows me to move around and get off the mattress easily.
I have the exact same model but from a previous generation which is perfect for my needs . Wanted to get one from another room , but was disappointed that the feel is not the same. It doesn’t feel as firm and the foam stays indented too long after lying on it. The result is that when I move to a different position, it feels like I am climbing a hill - very uncomfortable .
