We now have a Simmons Comforpedic - their version of the Tempurpedic. It was about half the price, and it has a bound edge instead of it just being cut off straight, which I liked. Have had it about a year now and I'm sleeping pretty well on it.
We too had a sleep number. also hated it. We sold it the day after we bought it (got it from someone who said “they didn’t need it”. I suspect they hated it too)
It was a queen. All the foam around the actual bladder made it IMPOSSIBLE to sleep on. My wife likes a soft bed, I like a firm one.
Every morning we had that bed I’d find myself on my wife’s side because once I got to close to the middle it would suck me in (her side was lower/softer)
We now have a Simmons his and hers (I think that is the model) her side is soft, mine is firm. It’s still a bit of a problem if I get to close to her side as the soft side will suck me in, but my side is much larger considering there is no air bag or 12 inches of foam around it.
We both love it.
