Frequently asked questions
What is a waterbed insert mattress queen?
A waterbed insert is a foam or gel topper that fits inside a waterbed frame, replacing the water bladder. It transforms the bed into a conventional mattress using the existing frame and support system.

Most standard queen waterbed frames accommodate 2-inch inserts. Check your frame’s interior dimensions and ensure the insert matches. Some frames may need a support deck if not present.
How do I clean a waterbed mattress insert?
Remove the cover if possible and machine wash according to the manufacturer's instructions. Spot clean the foam core with mild detergent and air dry. Avoid soaking the foam.
