We like to think of the quick lock metal 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 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 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.

Not a lot to say, it's pretty standard. Be careful with the long center support rail. Make sure if picturing it top to bottom, you have to make sure that center rail is in place the correct way, or, you end up tearing it apart and re-doing it. I'm just saying.. Mike. Bend, OR. Sun Mar 29 2026

My partner and I have been using this split frame for a few months now and we love it. This is our first hollow box spring after living with an old coil box spring for so long.

I’m very disappointed with this purchase. The box looks like it should be good quality, but unfortunately it arrived in poor condition. I contacted customer service to report the issue, and while they offered a 20 discount, I asked for a bit more since I really don’t want to go through the hassle of returning it, buying another one, and waiting again for shipping. They asked me to wait 24 hours for a response, so I’m still hoping for a better resolution. This is actually my third recent order with problems, which is very frustrating. I’ve been a Wayfair customer for years and never had this many issues before. Really disappointed with this experience. I received an email from Wayfair saying they are going to credit back to my original payment method, which I appreciate. I already finished building the box spring and, as I mentioned before, it does look like good quality overall. I really hope I won’t have any problems with it later on. I’ve been a loyal customer for many years, so I’m hoping this issue was just an unfortunate experience.. Veronica. Jacksonville, FL. Tue May 05 2026

Just what I needed. I found it hard to find boxsprings that you don't have to assemble! I did NOT want to have to assemble them. These are good because they ship in two not-too-large boxes. I was able to handle them myself without help. You simply unpack, unfold it, and put it on the bed. No assembly required. Taking off one star because there were a couple staples poking out of one of them, but once I laid it flat, that was the part that went together so they are not exposed in any way.. Kg.
