Sleep Number/Air Pedic….overall not recommended

Sleep Number

I dont hear many people recommending this bed. Is there a reason why?

I read in tutorial that a heavier part of body like hips will displace air to other parts of mattress. I guess that is bad. I havent tried it yet, but I imagine there might be hammocking.

Air Pedic

SN has 1 air chamber per side and Air Pedic had 3 chambers. AP has 1 section just for hips. I tried the AP 500, 600, 1000. Hips and head/foot can be adjusted independently. I guess there might be hammocking under hips, but so slightly that you dont notice (because its a small section).

Id be getting air bed because of my back pain and Im a back sleeper at 225 pounds. Wife is 100 pounds.

Would I be making a mistake by getting a SN or Air Pedic bed? If I have lower back pain, which other mattresses should I consider?
