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 ended up making the plunge and bought a sleep number bed. Because of my back I like a firmer mattress while my wife prefers a softer one. We got the split king with the adjustable base. It was EXPENSIVE but worth it.

Not sleep number. Sure you can infinitely adjust it, but it's still just a hard air mattress under a couple layers of foam. I have a rotator cuff injury that got worse with the bed because the soft layer is so unforgiving once it's compressed.

If you're not sure and don't want to commit, why not try a Sleep Number bed? My wife and I have a split king with an adjustable platform (not Sleep Number brand). It's saved us time and time again from various physical ailments and positional requirements.

We got a sleep number several months ago and also love it. We went with a solid base so it doesn’t adjust that way (and saved a decent amount on cost) but being able to adjust separate sides of the bed for firmness is awesome. It’s also sleeps so so so much cooler (temp wise) than any of the memory foam/hybrid mattresses we had for the 15 years prior. Highly recommend. Glad to see long term owners commenting here - I’m hopeful ours lasts a long time.

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 had a king size sleep number for about two days. No one tells you the king size has a huge, uncomfortable bar down the middle and no matter what you do, the air mattress pushes you towards that bar. You can’t fix air mattress physics. Also, it’s not everything but sex on two twin air mattresses glued together sucks.

I am a side sleeper as well and I sleep with a CPAP mask on. The most comfortable mattress I’ve used is a Stearns & Foster pillow top. Very comfortable and support. Also consider an adjustable base. The sleep number mattresses and base are amazing also because you can adjust the settings. My life goal is to get one.
