Serta iComfort Observer Pillowtop Reviews

I have had this mattress for 2 months. If you are wanting softness with support, you will be pleased with this mattress. When laying on it, your midsection will sink in 2-3 inches and give you a "hugging feeling", which I actually liked. After the softness, you'll feel the support kick in. This mattress helped immensely with lower back pain. However... The one thing I could not get past is the lack of heat dissipation. I removed the light summer blanket I use during our hot summers, and only used a top sheet, but that didn't help at all. The longer you lay on the mattress the more you can feel the heat coming up from below. I felt as if I was laying on a warming plate - not hot, just constant warmth. My bedroom has a ceiling fan & individual control of air conditioning temperature, so the room temp can be adjusted quite cool, but the heat in the mattress still caused many sleepless nights and/or tossing/turning. Also, after just 2 months of use, the side of the mattress where I get in/out of the bed collapsed in half. Normal mattress height is approximately 14", but when sitting on the edge it was 7". The other side of the bed remained at 10" when sitting on the edge, so I am certain there is a defect on the one side. Too expensive a mattress to have these issues, especially in just 2 months. Kudos to Sam's Club for their excellent return policy.
