“We had bought new zip lock mattresses for our Superking bed and we were finding them a little to firm .
The Superking topper works well , it fits the bed and stays in place . The firmer side works well when hubby has a bad back and I can stay on the softer side.
It was an expensive outlay for us but we are glad we chose the Revolution Topper , it has given us a good nights sleep with options !”
