I rate this box spring as fair because it was the cheapest king box I could find, and, you get what you pay for. The box itself is good, just tedious to put together. However, as all the other reviews state, the cloth cover absolutely does not fit. It tears very easily upon trying to get it zipped up and there is NO way that it will close properly otherwise. This was frustrating, time consuming, and upsetting. My husband and I attempted this task (of JUST zipping) for over an hour. We wound up leaving half of it unzipped and just placed a sheet over it to hide the metal. It's not really a huge deal to us but it's not right that the manufacturer doesn't correct this. We're hoping this box does not do any damage to our new mattress...

I purchased to replace a squeaky wooden box spring - very satisfied with the purchase. I did not read the some assembly blurb so my husband was surprised when it arrived in 4 days. It needs full assembly! Not too difficult but assembly is not "some" and the instructions are sketchy at best. My husband assembled by himself including putting on the cover. It looked perfect and fits perfectly in the king frame. Tracking number was not accurate for Fed Ex so we could not track purchase; however it arrived quickly. Definitely would recommend but know you need to completely assemble. Be patient or don't order it.

The instructions a bit confusing but overall the BoxSpring is great. One issue the rails will come out and do not really fit snug and the COVER does not fit. I called Zinus and they are giving me difficulty be careful and if you order online they will not accept purchase history as proof of purchase and Reps are rude.

The frame pieces could?ve been labeled and the fabric cover could?ve been a little bit bigger. The pieces that like hold the mattress just lock in. Sorta wished there was at least the option to screw them into place. All in all it does its job, fits our frame well. Very firm sadly but that?s my bad for not realizing that it wasn?t an actual box spring.

This Box Spring needs some assembly. My wife and I are 73 years old and had it assembled in less than one hour. This item is the best "thought through" assembly I have ever seen. You will literally never have to replace this box spring. 1st class parts from beginning to end, looks great, and will perform great. I promise it will surpass all of your expectations.

Almost 24 hours (in 2 hours it will be 24hrs) and the mattress is very firm and the coils can be felt poking through the top layer is very thin like very thin its like a sponge on top of springs if you lay on top you can feel them the card said to wait 72 hours will be back when the time is up and will update.

Assembling the box spring is fairly easy. I liked the box spring but will need to return it because the dimensions are smaller than the mattress so it hangs out on the sides. This box spring is 53x74x9 and the mattress is 54x75 so make sure that matches when purchasing.

Unpacked box. Tried to follow the "Easy as 123 " photo instructions. Useless. There weren't 2 "#1" peices. Actually thought one of them wasn't in box. Shipping said 9 frame peices. There were 9. Finally looked at bed frame picture. Laid out peices on bed frame. Only thing I used instruction sheet for was to see which screws went where. Could have saved myself 15 minutes if I just would have done that in the first place.

I could be prematurely reviewing this, meaning it probably is a good a box frame. However, putting it together was very difficult. The directions coupled with the way the pieces were labeled were hard to read and the screws were very finicky when assembling, even with a drill. So again, my rating is not based on the quality of the product but rather on the assembly.

Box springs have... springs. This doesn't. It's a metal torture rack no different than every other cheap foundation made for beds today. Anyone born after 2000 probably doesn't even know what a real night's sleep is. Box springs have actual springs, not metal coils that don't move. Imagine the difference between sleeping on a metal slab and sleeping on a trampoline with give. Box springs have SPRINGS. This doesn't.
