About this item

Product details

The Mainstays Full Mattress Foundation gives your mattress a steady 9 in high-profile base with the look and function of a traditional box spring. Its steel frame provides the underlying support, while no tools are required for assembly, so you can get it ready without hunting for hardware. The foundation works with innerspring, memory foam, and combination mattresses, making it a flexible fit for a Full-size setup. When you need to move it or tuck it away, the foldable construction lets you store or transport it more easily, and a 100% polyester white jacquard cover keeps the surface neatly finished for everyday bedroom use. Please note that the mattress and bed frame are not included.

Pleasantly surprised

I was uncertain about buying this bed frame, but glad I did. It was easy to put together and is holding up well for two adults. I did purchase a bunkie board to ensure a solid surface for our mattress and to decrease risk of bending one of the metal slats. After 2 weeks , I can say it’s working and I’ve heard it squeak maybe twice.

A little Flimsy

A little Flimsy on parts of the top rails. Easy to put together though. Price point was ok. Hopefully it lasts

Easy setup

Very simple to setup (less than 15 mintes), with easy to understand instructions. Material is decent for value. The cover is a snug fit, so you to need to adjust the cover to be centered in order for the final corner to stretch.
