I bought a foam mattress and unfortunately did not do my research and I had the wrong type of bed frame. There weren't enough slats and the mattress dipped in the middle and wasn't sturdy. So I needed a foundation to fix the problem; I did not want one with lots of height because our bed is already pretty high off the ground, so I found this one at a good price. It arrived on time and intact, it's already put together (no assemble required) so just remove the box and pop it underneath your mattress. It has worked wonders!! Our mattress is now working the way it's supposed to and the foundation doesn't slide around, it saved me from having to get a new bed frame.
