r/Mattress on Reddit: Losing my mind over adjustable split king decision
February 12, 2025 -

We are looking to get a split king adjustable bed. My fiance moves a lot in his sleep and sometimes snores and I’m a light sleeper, and I cannot do memory foam it’s way too firm for me so we want the split king. I’ve looked up countless brands, every brand seems pretty good and then I see threads saying it’s the worst mattress/company of all time. I’m going insane trying to decide on one.

Sleep number is the only one that I can’t generally find terrible reviews for - most people seem to like those beds for a long time or so it seems. Main downside being how pricey it is. Anyone have thoughts on sleep number split king or any other brand recommendations?

Owners of split king beds - what's your honest opinion?
We started out DIYing a king. Bought all sorts of different kinds of topper pieces. Eventually we decided we each needed different feels/firmness. So we sliced up all the layers into twin xls. Because my side is firmer than hers, you can definitely feel the difference if one of us rolls onto the other’s side. I either dip down into softer side like I rolled off an edge and she has to climb a bit when she rolls to my firmer side. So assuming you end up a good bit different, you will most definitely notice the split. Now, we put a stretchy mattress cover over it so you don’t fall in between the pieces as they’re snugged together, but it’s obvious where the separation is. But it helped us get the sleep we needed since we stopped trying to make one bed work. But we don’t have an adjustable base. More on reddit.com

split king adjustable mattresses sliding to the side - how do you stop that?
I went the route of potentially voiding the warranty on my base because nothing I found or tried helped. I bought two sets of the link below and screwed them into the corners of my adjustable base. Worked like a charm https://reverie.com/two-corner-retainer-bar-kit More on reddit.com

What's the thinking on split king adjustable "smart beds"?
We got the non split king. It died in a month or two. Worst sleep we have both ever gotten. I take turns on the floor with a Korean bed right now it's so bad. It was wonderful at the start. Customer service has been great. King koil and distributor. Wish it worked out. I do think the advertising vs what you actually get in the app is a quite misleading... the app doesn't do much it looks like it's in beta or something compared to the advertised thing.
