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.

How to Keep a Split King Mattress Together - Amerisleep
November 13, 2025 - Some split king foundations include a thin strip of material in the center that fills the gap between the two bases. Platform beds with solid surfaces provide more stability than traditional box springs, which can allow more movement. Adjustable bed frames work well with split king mattresses if they include syncing features that keep both sides moving together.
