I should have bought this when I bought my Purple mattress 5 years ago! Using a regular box spring under a Purple mattress will cause the grid to lose its shape and creates valleys in the mattress. Placing the Bunkie Board on top of the box spring restored the grid to its natural shape, and NOW I sleep on the mattress just like I did when I got it home! I'll be buying these for EVERY SINGLE Purple mattress I own!!!. Yokasta. NM. Mon Oct 19 2026
