9. Video: Does it work with a mattress topper?

Yes, it will work with any mattress topper, and it should hold your mattress topper in

place. The trick to the Better Bedder® is to place it so that it grips the sturdy sides of the mattress, not the topper. Pull down the Better Bedder® so that it rests about two inches under the topper. Put it on once, and that's it!
