Great night's sleep

I initially bought this with the 9 inch box spring but it was way too high, so I worked with Serta and Sams Club to change it to a 5 inch boxspring. Both reps were helpful and I was abl to accomplish the exchange in about ten days at no charge. The mattress is firm but not hard. I like the gel foam which gives substantial support and is not too mushy. The bed is about a 3.5 on a scale of 1-10(soft). I live in Florida and haven't found that the gel foam produces any heat at all. Serta gives a 120 day warranty for this hybrid model , so you can change it if you don't like it.

Not what I imagined

This bed has made me miserable. I dread going to sleep at night. I cannot get comfortable. I wake up with back pain throughout the night. It is so uncomfortable I had to get a memory foam pad to place over it. I was waking up with numb, painful heels when I rolled onto my back. Sad thing is, the memory foam hasnt helped much. This bed is definitely not cooler. In fact, its very hot. I wake up hot and in pain constantly. Unfortunately, i am unable to returnit until I have had it for 30 days. I would not recommend this mattress to anyone.
