Gap Filler Needed for Split King (non-adjustable)?

Hello! I work for GoodMorning.com and just wanted to chime in.

One thing to be aware of is to ensure the mattresses don't move around so when you do place them together, there's less chance of space between them. Do get in touch with the customer care team of the mattresses you're purchasing, but you might consider placing untreated plywood under the mattresses to keep them from sliding around.

We hope this was helpful!

Sleep number flex top king gap filler.
That works for the mattresses that are two twins pushed together but I have the one that is only split at the top. I can't find anything that is for that type of mattress. More on reddit.com

What is a bed gap filler used for?
It fills the space between two mattresses or between a mattress and bed frame.
A bed gap filler is a foam insert designed to eliminate the uncomfortable space that can form between two separate mattresses (such as twin beds pushed together) or between a smaller mattress and a larger bed frame. This creates a seamless, more stable sleeping surface.
