Take a look at Sleep Number. It's an infinitely adjustable air mattress. Our first a full lasted 25 years, it's replacement a queen now going past 5 years. They offer a 100-day in-home trial and a 15-year warranty.
My experience was just the opposite. I had a sleep number bed that had foam edge support and it just not very good at all on the edge. I was sliding off like crazy. I replaced it with a sterns and Foster lux estate that has special coils on the perimeter and it seems to be much better. I haven’t had it as long though.
I’ll chime in about using foam for edge support in a mattress. I had a sleep number mattress for years and the cover stretched so that the mattress tended to overhang the boxspring. Also, the edge support was a block of hard foam. As the years went by the hard foam just sagged in the spot where I sat to put on my shoes so I would have to find other spots to sit until I was sitting at the foot of the bed and that didn’t even work anymore. I also had to keep shoving the mattress over so it wouldn’t overhang at the edge where I sat. When it was time for me to buy a new mattress, I found one that had a special surround of springs on the edge to give a different kind of edge support. It’s too soon to know how it’ll hold up but no way I was going to buy another one with hard foam around the edge.
Using a firmness adjustable cooling mattress from Sleep Number. Keep it dialed up pretty dang firm because if I sink down there’s gonna be serious back pain waiting to greet me in the morning. Wife says it’s like a board, lol.
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.
Cannot recommend sleep number enough for you situation
I like my Nectar mattress that I got on Amazon for less than $700. I prefer it x100 to the SleepNumber that I spent thousands on.
Love our Sleep Number. We’ve had it 5 years or so.
Just speaking from personal experience, my ex and I tried the sleep number mattress and we hated it. Ended up getting a new Beautyrest Harmony in medium firmness. I loved it as is, but it was too firm for her so she got a 1.5” foam topper. I couldn’t stand it. We split and she took the bed, then I got another nearly identical BR Harmony in medium, and love it as is still! So far, the mattress is just on the floor, as I’m building a custom platform bed frame for it https://preview.redd.it/rcig3qol96yf1.jpeg?width=5297&format=pjpg&auto=webp&s=f7452d5d0111d07ab3ce5da3fdf19e429aa88c73
It was okay for me. I found it caused me to play with the numbers a bunch, and it was very hot in the summers. I also think at one or two points over the years I had to patch it. It also sometimes would lose calibration.
