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

I was not able to use the bed bridge pad with our adjustable twin beds. 1. Would have needed a king fitted sheet to keep it in place. 2. The head and feet position heights between our two twin mattresses are too different to keep it in place.
