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.

My wife and I have a flex top sleep number king sized bed. We love the bed, but I would love to find a product that I could use to fill the gap when I want it filled. So far I've looked all over online and cannot find any products that are intended to fill it. Has anyone found anything for this?

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

Anyone have a split king bed? I need to fill that gap! - The Chat Board - The Well-Trained Mind Community
December 29, 2024 - We recently purchased an split adjustable base bed with 2 twin XL mattresses. I now know why they didn't have one on the floor-that gap is much bigger than they pitched it. I know there are products to bridge the gap, but Is there one you would recommend? Thanks!!
