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

Go on Amazon and look up something called a bed bridge. This has helped a ton of my customers and may be a good fit got you.

Will a mattress topper really help keep my split king mattresses together?
Yes, a mattress topper can significantly help keep your split king mattresses together. A single king-sized topper creates a unified surface across both mattresses and helps bridge the gap between them.
The weight of the topper adds stability that prevents the mattresses from shifting apart during the night. For best results, choose a topper that's at least 2 inches thick and made of memory foam or latex that holds its shape well.

Why do my mattresses still slide apart even with non-slip pads?
Your mattresses may still slide apart with non-slip pads if you're not using enough pads or if they're not placed correctly. Make sure the pads cover the entire bottom surface of both mattresses, not just the corners or edges.
The pads might also be collecting dust or debris that reduces their grippy texture. Another possibility is that your bed frame has structural issues that cause movement regardless of the pads, such as uneven legs or a sloping floor.

Can I use a split king on a regular king bed frame?
Yes, you can use a split king on a regular king bed frame as long as the frame has proper center support. The dimensions of a split king (two twin XL mattresses) match exactly with a standard king frame.
However, regular king frames may not have features designed to prevent mattress separation. For the best results, add non-slip pads between the mattresses and frame, and consider using mattress connector straps for extra stability.

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.
