I thought this came assembled. Not sure if I misread the description. Overall it is good and has held up for the past month but one of the pieces was slightly bent and now it is not securely put together because of it. Not sure if that'll make a difference in the long run but returning it seemed like a lot of work.

We bought 2 and returned 1 of them after finding out you had to put them together yourself and not being satisfied with the set up of the first box spring. We were under the impression these were 'premade and ready to set on the bed'. Not only does it fit very snug in the bed frame, almost doesnt fit but it sits high too. Dispite having the mattress on top of it, my son has to be careful not to knock into the lip of the box spring or it'll leave a nasty bruise on his knee.

I purchased this Zinus box spring. In spite of my having arthritis of the spine, I deceided to try to put it together myself before getting help. I was able to do it alone. It was very easy to assemble. My matress fits on it perfectly. I sleep soundly and extrememly comfortably. I highly recommend this product.

Can't believe that a box spring that comes out of a 12" X 12" X 78" box works so well

Just what we needed. We are mounting our headboard to the wall and wanted to be higher off the ground. Works perfectly. The cover is nice but not good for show. We’ll need a bed skirt to cover the swirls

Easy to assemble. Love the removable, washable cover. Also love the fact that this will last for years and can be easily disassembled if we move. No more buying cheap foundations that collect dust and inevitably end up on a landfill.

Was skeptical about putting together a box spring, but decided to try it because the price is very good. Well now, it is just as sturdy as traditional box spring. Adding nine inches of height, it also is nice looking.

very nice, you do have to put it together yourself but its easy to do, no more sounds with getting in and out of the bed I'm glad I got it me and my mom have ordered this box spring and I'm going to order one for my son.

Assembling the metal box spring was as simple as A, B, C. It took me about 15 to 20 minutes to complete assembly, and this was solely because I was being extra meticulous. I have owned wood box springs in the past and this metal upgrade (if I can call it that), certainly seems sturdier and I suspect likely to be more durable. I assigned 4 stars simply because I cannot predict what condition it will be in after the first year and beyond.

At first I thought we had received the wrong item. I was expecting a large box and was surprised to see a narrow, long box. Upon opening the box I found components for putting together a box frame. After the initial surprise, I found the instructions were clear, all the parts labeled and present, they even threw in two extra bolts, just in case! The little ratchet tool was not very useful, but the hex key was more than sufficient to put the pieces together. This is a really good and useful box mattress.
