After deliberating on getting a purple mattress i decided to try the bed out for myself and my brother, (2 actually brought same model). When you first crawl into the bed, it kind of feels like waterbed underneath you. The bed however is firm and does have support for your back and sides. I sleep on my back at first and then end up on my side throughout the night. When I move, I notice the bed does contort to your body quickly. My biggest issue on my last bed was that my feet would always drop and will not elevate because of a whole, however the purple bed always has my legs in the right lifted position. I had the mattress for a couple of weeks already and myself and my brother agrees it's the best mattress we had ever purchase.
