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!

Bought this thinking it was a conventional box springs because of the product photo. Was surprised when it arrived in a relatively small carton because the design requires user-assembly. This solved my biggest issue: How would I get it upstairs via my narrow staircase? Assembly of the steel frame was straightforward with all components numbered and all fasteners supplied. Even spare fasteners and all necessary tools were supplied. With its zip-on fabric cover, this product looks and functions just like a conventional box springs. I am a fan of Zinus!

Very sturdy frame. Instruction is lacking. Pictures helped some but it needs improvement. Metal pieces have marking UP to indicate direction of assembly, but the hard plastic pieces do not. The mid-section pieces need to have the open end facing up. If installed upside down, metal piece can be removed by press on the push pin. The issue is the push pin sink in and lost inside the metal frame. I almost return this frame. Luckly, I found an old metal window hanging curtain bar long enough to push the push in out of the frame. To reinstall the push pin, best use a small, long nose pliers. Once assembled, the frame is solid, no crack or creek as some stated.

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.

Easy to put together. Fit perfectly onto the queen size bed frame. This was exactly what we were looking for as the bedframe is a platform style bed. This box spring doesn't come with feet it is meant to fit right inside your furniture. we give it 5 stars!

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.

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!

[This review was collected as part of a promotion.] I absolutely love this box spring!! I love that it was very easy to put together, and did not take long at all to assemble, like total time was barely 15 minutes! The cover fit great and made it to where our cat doesn't go under the bed and claw the mattress anymore. Shipping was fast as well. I definitely recommend this product!

I purchased this and it was delivered on time and it was easy to put together. The only thing I noticed is the directions as easy as they are, they are not as specific as they can. Otherwise I would recommend this items to anyone who nwwds a box spring.
