Funny you should ask this question. We have had ours for 4 days now. We got the queen 7000 with the wireless remote. We ordered the foundation, but ended up not putting it on the frame and just used our old box spring.
The bed will take you about 30 minutes to put together. The instructions were very easy.
My sleep number in the store was 45, but I upped it to 50. Actually, the first night I had it I slept at 35, but it was too soft.
Now that I am at 50, I am happy.
However, dh (the one with the good back) is having problems finding his sleep number. He has woken up every day with a hurting back.
The bed takes a night or 2 to get use to, but after that it's good. Well, at least it has been for me.
It does have a different feel than a regular mattress. Actually, the first night I thought it was rather noticeable that I was sleeping on air. After the first night I couldn't tell though.
Other people have said that they notice the divide in the air chambers and that they don't like it. I think that it is noticeable, but something that you can get use to. Especially, if you like a firmer bed.
If it were up to me we would be keeping the bed, but it looks like we will be sending ours back if dh doesn't find a good sleep number. What a pain too because he has already crushed and sent the boxes to the recycle dumpster. We have to go out and buy boxes to ship it back.
Hope this helps!
