A few of my family members have the Purple mattress and LOVE it. I wanted so badly to love it, too!! Unfortunately it did not work for me at all. I've never been so roasting hot at night. I've been sweating, tossing and turning from overheating. Apparently my body doesn't like to sleep on hyper elastic plastic polymers. :-( In addition, it was too firm for me. I am a side sleeper, and am light weight. I woke up every morning with upper back pain. I think I'm more sensitive than lots of people. If you're heavier and are a back sleeper, I'm sure you'd love it.
