I searched for months to find a bed that I wanted. I researched temperpedic sleep number, knock offs, Gel foam vs memory foam, thick vs thin, I was a woman obsessed. In the end I chose a Gel foam memory mattress by temperpedic. I got a 60 days exchange for free promise with it. If it slept hot or too soft I could change it for any other mattress in the store, not just that brand name.
I LOVE this mattress! it sleeps cool, and its soft and comfy while being firm enough to hold me up. Many mattresses were so soft that I sank in and I am sure that would have killed my back. I got the medium firm with a 4 pound density and a 13 on the softness rating 10=hard 16 = extra soft. They delivered it for free and while it sTUNK! and took 3 days to air out I am ever so glad I got this. HUGE difference in how I sleep.
Be careful of some mattress pads. The mattress many sleep cool, but if you put a fiber fill pad on it, that too will reflect heat.
Enjoy your new bed!
