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

How to keep a split king mattress from sliding?
Use a Bedbinders connector specifically designed for split kings and adjustable bases. Place non-slip material under both mattresses where they contact the foundation. Ensure both bases are properly synced if you have an adjustable bed. Check that your mattresses are the correct size for your foundation. Avoid DIY solutions which can restrict adjustable base functionality.

How to keep two mattresses from sliding apart?
Use a Bedbinders mattress connector between the mattresses (most effective solution). Place the connector at mid-mattress height, typically 4-8 inches from the top. Add non-slip material under both mattresses for added stability. Ensure your bed frame has adequate center support to prevent foundation separation. Use a unified mattress pad across both surfaces if additional stability is needed.

How to fix a slipping mattress?
For immediate fix: Place rubber mats or non-slip pads between mattress and foundation. For two-mattress gaps: Install a Bedbinders mattress connector. For platform beds: Add L-brackets or mattress stoppers at the foot. For box springs: Use mattress straps that wrap around the entire bed. First check: Ensure your bed frame is level and all components are tightened properly.

Our split king mattresses come with connecting straps that you can use for this. If you have laminate, hardwood or tile flooring, pick up some non-slip furniture coasters. Furniture coasters will create friction and keep your bases from migrating apart as you get in and out of bed. You can also pick up a “bed wedge” or “gap filler.” This accessory is usually made from memory foam.

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!!

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?
