One solution that will allow you to still individually move your sides would be to use a flex top or solid Sleep Number sheet set. It will keep you from falling in the gap, but still allow movement. I have some customers who also use a flextop or solid topper or mattress, pad and sheet, however the more layers on top tomorrow awkward individual movement might be. The good thing is that with these solutions, you are not forcing more into the split, and as needs change, or as you figure out how to cuddle or have activities side to side they can be removed.

r/sleepnumber on Reddit: Split bed gap filler?
October 14, 2023 -
So I've had a king size split bed for awhile now. I like the individual control, however, I don't like that the split in the middle really gets in the way of cuddling and activities. Was wondering if anyone has recommendations as to what they use to fill in the gap from time to time aside from just a blanket or pillow
I really wish sleepnumber had a perfect formed foam cutout I guess

4 Problems with Split Kings (& How to Solve Them) | GhostBed®
As with the gap filler option, using a king-sized topper means you won’t be able to raise one side of the bed at a time. Add a headboard. A headboard will keep your mattresses stationary and secure. If you already have a headboard you love, great! All you need to make it work is a set of headboard brackets, which we sell separately here at GhostBed. And don’t worry, your split king won’t side apart while getting intimate.

What to Know Before Purchasing a Split King Bed - Sleep Advisor
July 26, 2024 - The gap filler creates a small bridge and eliminates any dip between the bed. You can place it into the space between the mattresses either before you’ve made the bed (using King sheets) or after (using Twin XL sheets). Some bed frames allow the user to screw a headboard directly into the base. However, not every Split King comes with this feature, and the ones that do are expensive.

r/sleepnumber on Reddit: Best bridge/gap filler for Climate360 Split King
June 4, 2024 -
I want to link the two sides of the adjustable base and use a bed-bridge under a king mattress pad to make the split king more like a king. Any suggestions on the best bridge/gap filler to get? The angled edges of the two mattresses seem to yield a bigger gap at the top than what I see most bed bridges advertised for.

I wish one would work! I bought a thing that goes between with a strap to pull around to get them closer. Garbage. Now I just stuff pillows in the middle. It really sucks that there's no way to make it feel like an actual king. I would never do split king again, but now I'm stuck with it. If you find something that works, please post!

If you want to sync both sides to move together you just need to use a king fitted sheet. In my experience anything you put in the gap will force it wider over time. If you want to spend for a king size Climate mattress pad (breathable) that would help, too. Ordinarily I’d suggest a king topper pad to eliminate the gap but not on a Climate 360 since it would black the airflow.
