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?

We got a split king Dreamcloud mattress and really hate the full split setup with a huge canyon sized gap in the middle.
We are thinking of returning it and replacing it with a split top mattress as we need the adjustability for my wife's heartburn but we are thinking the split top (flex top) style will be much better as at minimum the beds will stop sliding apart all the time.

I am having a really hard time finding split top king sized mattresses. Figured I come here and see if anyone has some recommendations. Our budget is 4k for the mattress.
