‘Sleep Number’ but it’ll cost ya.
I don’t like the company - but love the bed.
One’s bed hardness needs change - even over one month, and definitely over age.....life itself is changes.......this is the only one that can change with you, mood, injury, whatever.
Love the way I and wife can change settings for our current needs.......no fixed firmness mattress can do that.
Too expensive - but in the long run, worth it.
We looked into sleep number but the price was a killer. We finally just picked up a gel topper at Costco and put it on our pillowtop mattress and it worked like a charm. Now we have plenty of time to worry about getting new one.
