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.

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!

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.

Best box spring I ever purchased. Totally fooled me with the box it came in. Easy assembly and good directions. Quality in every part. Sturdy and well made, cover fits perfectly and easy to cover. Extremely well made. Would definitely recommend.

I bought this box spring about 2 months ago, delivery was free and fast. It came in a long box and assembly was required. It was pretty easy to assemble if you follow the instructions. It is an all metal frame, with no springs, then you cover it with a thin fabric that closes with a zipper. It fits the base of the bed perfectly. The only thing is that it came really dusty, so make sure to clean it before assembly, so the carpets won't get dirty.

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.

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!

Surprised by the high quality product. It's first class design and construction. I am getting more for all the beds. One thing is frustrating ... instructions. The drawing is NOT accurate as to refer to a part. Especially the connecting pieces as which side is UP ! The drawing is soooo tiny and can't make out the part at the corner sections. it's easy to take it apart if not assembled correctly. The parts are NOT numbered and you have to refer to the drawing each time and try to figure it out....which is not exact by looking at it. Makes a difference if it's UP or DOWN when install it. Don't let this deter you, the product is EXCELLENT but the instructions need LARGER drawings then it's easy to assemble.

When I moved I had to throw out my box spring for my memory foam mattress. I looked on line for about a month and found this one based on reviews and price. The first night I could not believe how my lower back pain had pretty much gone away. This is a solid frame and quite reasonable. What a difference !

I read the reviews after I purchased it and noticed a lot of people complaining about putting it together. It comes in a box, it has metal rails, directions, and even comes with the tools. We layed out all the metal rails and screwed them together. Then we put this large zippered pillow case on. I love that if you need to move, you can easily take it apart or if you want to clean the fabric periodically you can. Not like those old school wood ones. This type of box spring is new and improved. Yes, you have to put it together but it is worth it!
