Twin-XL

King

California King

Made with durable materials for excellent support and stability.

Can be snug, but also varies in ease of installation.

Just got this delivered today.  It literally took me less than 5 minutes to assemble the frame it was that easy!  The cover for it took me a little while longer, only because I was working by myself and the frame was already on the bed, but still...10 minutes from start to finish is not bad!  Seems very sturdy and made a big difference with the mattress on it WITHOUT the box spring.  I feel like it was a great deal for the price!!  Very happy with the purchase and it was delivered right to my door!

Great box spring so far!

walmart.com

Bought this spring mattress box to replace an old high spring box from my guest bedroom.  I loved it so much that I'm  buying another one for my bedroom. This spring mattress box is sturdy, perfect height and it only took about 20 minutes to assemble it without tools.

Super easy assembly!

Super easy to assemble, and put the cover on. I love that this one wont sag over time!! If we move again in the future, this will be easy to disassemble and it will take up less space! This one is the PERFECT size, not too tall, but not too short either.

10/10 WOULD RECOMMEND

Works great! love that it's metal. folds up if needed to be stored. also can wash the cover if need be. Will never use a regular spring one again. I actually ended up buying a 2nd one, was used to my old bed being higher. Bout new mattress and this 5in and sat to low. So i got the 9 inch.

Works great and sturdy

I was a little bit skeptical when I saw the size of the box as I bought a queen. I was pleasantly surprised at not only the ease of putting this together, but also the quality.  I would recommend assembling this in an open area and then taking it into the bedroom if there's not a big enough space to lay it all out in the bedroom itself.

So easy to assemble

Perfect size !! It came in at night and I was like no way I'm finna put all this together all in one night and that morning when I opened it and saw the instructions I was like THATS ALL I HAD TO DO ?????😂😂😂 ( full size 14 inch btw )

Great quality bed frame! Easy to assemble, extremely sturdy, very nice cover. We got it in the 5 inch height and it is perfect for our new king bed. If you're looking for a bed frame, buy this!

Best bed frame on the market

What a difference this made to my son's bottom bunk. He never knew how bumpy his mattress felt until he got this box spring support. Thrilled. Plus very easy to assemble and no tools needed.

Amazing!

so its sturdy, and easy to assemble, but i can kinda feel the bars through my 5 inch memory foam mattress,  and at least one of them popped out of place while i was sitting on the bed, and i cant pop it back in unless i takt the mattres and boxspring cover off... so that is gonna be a hassel, i almost want to glue these bars on so they will stay in place... outside of all that, its a fine box spring and i would recommend.

it shows legs on this box spring....there are no legs. 

it is just the box spring

The cover does not fit tight 

The instructions were not very clear
