## Description

As the backbone for solid mattress support, a box spring that falls short can make or break your night’s sleep. We developed the Smart BoxSpring® with unbeatable durability and rock-solid stability to keep your mattress in shape for years to come. And our latest quick assembly version gives you total confidence when it comes to setup, requiring fewer bolts and ingeniously designed with easy to use, tool-free brackets. With our simple, step-by-step instructions on hand, you’ll have this foundation built and ready to use within minutes. Built with a strong and durable steel frame and a versatile poly jacquard cover that slips right on, the Smart BoxSpring® is the picture of dependability for any mattress. All packed in a compact shipping box with everything included, even our 5-year worry free warranty! Now that’s peace of mind you can sleep on.

Review: I knew there were going to be a lot of parts, so I decided to be as organized as possible. After opening the box, I marked each group of items with a sticky note to make assembly as easy as possible. It took 45 minutes total to label, assemble, and put the cover on. I especially loved the mini ratchet tool that was included; it made tightening everything much faster and easier than using a standard allen wrench. Everything fit as expected and was easy to move into our rolling adjustment frame. The King mattress fits nicely on the metal box spring and does not slide around at all. It looks great and feels very solid. We are looking forward to having family visit and hope they enjoy the comfort. If you take the time to organize the pieces first and use the provided ratchet, this is a very straightforward and high-quality setup
Review: Would buy it again in a heart beat

The frame works great, except for the fact that it’s about 5 inches longer than my single mattress. So it’s a bit awkward looking, but functional otherwise.
