The Metal Smart Box Spring is an interesting product that ships in a long box and requires assembly at home. If you are handy or enjoy putting things together it’s probably for you! If you are not handy, assembling might be a bit challenging. I don’t recommend it for a latex mattress. I put my beloved Avocado Organic Latex Mattress on it and could feel the metal of the box spring beneath the gray fabric. I didn’t bother making the bed. I disassembled the frame, packed it up and will return it. My guess is that a traditional spring coil mattress, and a customer who likes putting things together, would a better match for this product. On the up side, it shipped in a long narrow box which makes it easy to carry upstairs.

Casper Foundations Bunkie Board and Slats

$360 was~~$399~~

Our foundation provides excellent support under any mattress and can be assembled in minutes -- no tools required. Older box springs’ slats tend to be too far apart, leaving room for a mattress to sag. Our foundation's slats are positioned a perfect four inches apart for optimal support. Engineered with solid wood, it has been rigorously tested for durability and proven to stand up to years of sleep.

It works perfectly and nice support for my mattress.. Jason. Washington, Dc. Mon Aug 01 2022
