ComfortMode™ Mattress

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 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.
