We're on our second SleepNumber mattress. First one lasted 12+ years until we decided to upgrade. When the time came, there was no question about buying another SleepNumber. We're 100% happy with SleepNumber beds. The newer one cost approx $4k

I came here to say get a Sleepnumber! I got one with my ex for the same reason, and when we broke up I kept the mattress and bed. My current boyfriend could probably fall asleep anywhere and on anything, but it was a nice luxury to be able to set the mattress for him to his liking. The most basic mattress they have is great and very affordable IMO.

I have a rather basic sleep number mattress and box, it’s not rated for that capacity but… I am well beyond it. So… make of that what you will. It’s the second one I’ve owed. The first one was a king, probably should have gone with king again but now we have a queen. If you’re unfamiliar, the system is pretty much an ultra rugged air mattress wrapped up in more traditional mattress covers. There’s a control box with a pump so you don’t have to blow it up (firmer) or let air out (softer) and left to right each side can set their own firmness aka sleep number. There’s a polymer box spring underneath. It’s sturdy af. It all comes flat packed and it’s a bit of a magic trick to get it all together. You’ll want some help. None of it is particularly difficult but you should have 2 people. For the bed frame, I picked a not the very cheapest tubular steel ikea thing and then doubled up the wooden slats they have for them. You’re supposed to use one roll per side spanning head to toe, and frame rail to center spar. But I bought two extras, one for each side. The extra one fits by being run toe to head, and upside down so that the wood slats fit between each other. Maybe hard to imagine but putting one in correctly makes it clear where the extra one fits. Zero problem. I had the king for 5 years. Absolutely loved it. The king got a rip in it through no fault of its own and we replaced it with our current queen, flawless for going on 13 years. It’s starting to show wear. The foam bits inside could be replaced. And that’s the real clincher… The mattress is easy to take apart and put together. The whole system is, ikea steel and all. That was one of the goals because we move so much. So I can replace the stability foam bits inside the mattress. The only problem I have recommending this is, the popular enshitification trend might be a problem. I bought all of this 13 years ago. Maybe they suck now IDK. Maybe the design is significantly different now and it won’t support my needs. I wish I could give a better endorsement, but no (zero) springs or firming wires or coil density issues. They don’t squeak although the frame does occasionally.

I love my Sleep Number bed too! We bought ours 17 years ago and it's still working perfectly. We have a king size and I don't feel my husband moving around during the night and we can each choose our own level of firmness.

A very old adjustable air bed we night when we got married 20 years ago. It was called a sleep number bed back then and I think it's called something different now. The nice thing is that you can actually order a replacement cover for the entire bed. We have done that twice, and even though it cost about $500 each time, much cheaper than paying thousands for a new bed.
