That's exactly what I hate about our current bed. Once it sucks you in, you're stuck for the night.Good morning Debby! They eventually form to your body. It's not visible when you look at it but when you lay in it ,it indents. They are hard to roll over in especially if you sweat at all! They should be made thicker too. The sad thing is we bought the adjustable bed frame so unless you want to throw $1500 out the door for that you have to buy another mattress like this. I think the next one we buy will be the best one they make, this was second in line. I used to wake up with back aches and that has gone away so I shouldn't complain. We paid almost $3000 for the set. My friend has a knock off of the sleep number which was still expensive. She doesn't like iit but her husband does. I hope you love yours for what they cost. If you don't, don't be afraid to return it.
We do get a 100 day trial with the new bed so if we don't like it, they'll take it back.
I'm glad your's helped with back aches!
