Frequently asked questions

What size beds does a 75 inch mattress gap filler work with?
It is sized for standard 75 inch twin and twin XL mattress pairings. Two twins side by side give you a king-style width when joined by this connector.

Does it work on adjustable beds?
It is designed for flat mattress setups. If you use it on an adjustable base, set both sides to the same flat position before installing.

How do you install a bed connector gap filler?
Push the two mattresses together, then slide the filler into the seam between them. No tools needed.

Is it noticeable when you sleep?
Sleepers usually feel the bridge under the sheets, not the seam. A fitted king sheet over the top creates a smoother feel.
