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

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!! More on forums.welltrainedmind.com

October 14, 2023Best bridge/gap filler for Climate360 Split King
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!

How to Keep a Split King Mattress Together - Amerisleep
November 13, 2025 - Use Physical Connectors and Non-slip Solutions: The most effective methods for preventing mattress gaps include using non-slip pads between the mattresses and foundation, mattress connector straps that physically join the mattresses together, and bed bridges or gap fillers that create a smooth transition between surfaces. Strengthen Your Bed Foundation: Regularly check and tighten all bed frame components, consider adding a sturdy headboard connected directly to the frame, and choose a foundation specifically designed for split king setups with connector hardware or locking mechanisms.
