I don't know if I understood the description long I thought it was a box spring the normal ones the old-fashioned kind with wood whatever it is. But no one comes in this tiny box that you have to build and put it together it's not that hard you kind of do need two people at the very beginning. And I guess it's okay my daughter doesn't care for it her mattress slips off all the time the only reason that it stays on is because it's against the wall but in the middle of her room it literally slips to one side into the other

I bought this for my king size bed that I had no box spring under. Was really uncomfy. Got this and was intimidated by it because of the need to put it together.. it was SO SIMPLE to do. Took me 30 minutes with interruptions. I love how it's just one piece and easy to move and wash the cover.

I read reviews of people stating it took them 15min to 30min to set up but for me it took me over an hour. The hardest part was putting the cover. It was too hard for me but hey I was happy I build it myself all alone. It does what it needs to thanks to my Serta mattress my whole bed feels great and looks so tall.

Able to fold up to fit in tight spaces a king size box spring would not otherwise fit into (such as up a narrow staircase leading to an upstairs bedroom) It is only because of this product that I was able to keep a king size bed in a master bedroom upstairs. The stairwell was so steep and narrow that only a regular full size box spring would fit (which was fine for the upstairs guest bedroom). Thankfully this king box spring was available and made it up the stairs easily! Now we can continue sleeping on our king size bed without a problem!

I ordered this item because our box spring did not fit up the stairs in my old 1920's home. I ordered is 2 weeks before it actually got to me. The delivery date kept getting pushed back every time I looked. Love the item though it was really easy to put together and simple to replace our big box spring!

I had been using my mattress just straight on my bedframe, which said no box spring needed, and having sleeping issues. I would wake up repeatedly with my back hurting, neck stiff, and just uncomfortable. Finally bought this after someone said a box spring would help, and it's like I bought a brand new mattress! It's actually more firm which I didnt even notice how uncomfortable sinking into bed was. I sleep through the night now, the pain has totally gone, and I feel like I just added another several years to the mattresses life.

Full disclosure, I thought this thing would come assembled. IT DIDN'T. But no problem. The instructions were clear on how to put it together. My wife and I did it in no time at all. The construction of it makes it very sturdy, and easy to move. I like that it is lighter, but stronger than my old box spring, which I felt tore and cracked all the time if I moved it. I wish the top side had a litlte more resistance to it to keep the mattress on top from shifting. But it's not a deal breaker at all. I love it.

The mattress began to loosen the top layer within days of purchase. The side is already feeling like it is broken down. We bought this for my elderly Mom and she thinks we should return it. Really not happy. The box springs came in a relatively small box and were easy to put together. A clever idea, we’ll executed.

I recently purchased a box spring mattress from Sam's Club. The service was excellent and the delivery method and time was amazing. I received my mattress sooner than I anticipated. The most pleasurable part of my experience was that everything was done online. I never left my home, yet received what I needed to complete my bed. Thank you Sam's Club!

I bought this to replace an awful cheap wood box spring that we had because it was just so loud. This one, though metal, doesn't even make a sound. I can honestly say, it has even changed the way the bed feels also. Getting much better nights sleep and may just keep my bed for a bit longer.
