## Description

We like to think of the Quick Lock Metal Smart Box Spring as the 2.0 version of your traditional mattress foundation. Made sturdier than ever by its substantial steel frame and with its game-changing assembly method, we’ve developed a better way to deliver great sleep to your door. Created with closely spaced slats to accompany your latex, memory foam or spring mattress, this durable box spring comes in three different thicknesses so your bed can be as short or as tall as you like it. The Smart Box Spring features our fool-proof Quick Lock assembly system, meaning you spend less time screwing in bolts, and you get to be pleasantly surprised by how simply and quickly it comes together. You may even pat yourself on the back once you’re done (in fact, we encourage that). We’re so sure of this foundation (along with hundreds of happy customers) that it’s backed by a 5 year worry-free warranty, so you can sleep confidently for years to come.
