On the surface the split top bed features a much desirable independent height adjustment for the upper body. That is great if a gap between the flex mattress at the head portion of the bed would stay constant.
As the mattress is used, a gap that was about 2 inches is now about 7 inches and spreading. The result is a very uncomfortable sleep experience when your hand or head is caught in the middle. Just the other day I had to assist my wife by helping to pull her arm out of the gap after being stuck. This is not safe.
We have resulted to placing a pillow in the gap which is not comfortable at all. Calls to sleep number have resulted in no satisfaction and being told there is nothing they can do.
How nice of them. My recommendation is to stay away from the flex style mattress.
Reason of review: Poor customer service.
Preferred solution: replace mattress with one without split.
I liked: In store customer service was very friendly, Local store and people are great.
I didn't like: Customer service, Lack of care after sale.
