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.

What if my mattress is too small for my bed?
For mattresses too small for their frames: Measure the gap size to determine the best approach. For gaps under 2 inches: Use foam gap fillers (temporary solution). For larger gaps: Install frame reducers or wooden inserts to decrease the interior dimensions. For severe mismatch: Replace either the mattress or frame for proper sizing. For two undersized mattresses: A Bedbinders connector helps maintain position even with smaller dimensions.

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

Bigger Bed In An Instant - Simply use this twin bed connector to make a king by pushing the two mattresses together and placing the bed bridge on top between them. You'd better cover it with a mattress pad or fitted sheet for extra stability. Proprietary Gap Filling System-The piece of foam attached special material to the twin bed connector is very sturdy with inherent structural integrity.

How to Keep a Split King Mattress Together - Amerisleep
November 13, 2025 - Some split king foundations include a thin strip of material in the center that fills the gap between the two bases. Platform beds with solid surfaces provide more stability than traditional box springs, which can allow more movement. Adjustable bed frames work well with split king mattresses if they include syncing features that keep both sides moving together.
