This product is great, I am 100% satisfied with this purchase. I am using this box spring with a Nature Sleep memory foam mattress. If you have an innerspring mattress your mileage may vary. My review as follows will cover several different aspects of this product and why they are great.
Portability: Who knew you could assemble a box spring instead of lugging around a 50+ pound bulky wooden frame? Once assembled, the frame is lightweight and much easier to move around than a traditional box spring. The next time I move I am just going to take it apart instead of it taking up space in the moving truck, very economical in that sense.
Assembly: Assembly was very easy, no mechanical inclinations required from the assembler. The set comes with an allen wrench/hex key and you use that to hold bolts in place while you tighten wingnuts with your fingers. Please ignore any reviewer of this product who said it was too difficult to assemble, took too long, or had confusing instructions, they are either lazy or completely incompetent. It took me about an hour to assemble by myself, and it would have taken even less time if I hadn't been half watching TV and drinking a beer while I was putting it together. The instructions aren't written words, but pictures showing which pieces to assemble with which bolts, but if you ever built a Lego set when you were a kid you should be able to handle this. It is easy to tell which pieces should be facing up during assembly, because most have a 'this side up' sticker. The pieces that don't, it either doesn't matter which side is up or you can tell which side should be up because of the notches the slats will fit into at the end.
The Cover/ Looks: The zip cover looks nice and the white sides are a soft plush. Make sure you sweep your floor before zipping the cover on though or you might get dirt all over the nice white part. Some people said that the cover ripped when they were zipping it up, that was not the case for me. The cover is a very tight and perfect fit, but the white sides stretch. So when you zip it on, don't just yank on the zipper as hard as you can, pull up on the white parts that stretch and it will make the zipper easier to close.
Durability: It seems sturdy enough to me. I have had for two weeks, no complaints. I have unzipped and re-examined the frame and it has not bent or buckled under the weight of two people or any vigorous activity. Could you bend the metal of the frame after you put it together? I guess you could if you tried to, but why would you do that deliberately? Putting a mattress on top of it and using as intended should leave you with no issues.
I hope this review provided all the information needed to help in your purchase decision, and I am sure you will be satisfied with this box spring.

After reading the mixed reviews on the quality and difficulty of putting this box spring together I mentally prepped myself for a world of hurt in assembling it. I’m not the most handy person and really suck at putting furniture together, but the thing was $149 and I needed a box spring. Anyway- after putting it together I can legitimately say this box spring was so much easier than the reviews made it out to be. I watched the very short video posted by the makers (wish it was slower) and got a better understanding of how to setup the frame. The number labeling didn’t make a whole lot of sense once I had it out and I was concerned some part were mislabeled, but if you watch the video a few times you’ll see that it all comes together as intended and all the parts are labeled correctly. All in all I was able to assemble it in less than 45mn. The thing feels pretty darn sturdy too! My only gripe is the cover, not sure what the heck that thing is all about, it does slip off easily as it’s only tied by elastics and should really be more of a fabric encasing with a zip up instead- but whatever, I was able to make it work with some tape. Also note that it doesn’t come with legs, as people have complained about this in the reviews- however, I’ve never seen a box spring come with legs/frame before, so I don’t know what the heck they’re complaining about. Overall I think this was an awesome purchase, especially for the price. Do watch the vids to get a better understanding of how the setup works, know that you’ll need to join the 2 largest bars into a cross and use the largest nuts and bolts provided to fasten them together in the middle- the rest becomes self-explanatory as the curved pieces become the corners, which are then are joined by the remaining rails that you’ll marry up by matching up the numbers labeled on both the corner pieces and side rails. It’s a little like a puzzle by the numbers. I’ll update on quality after few weeks, but so far so good! I have a very heavy mattress and weigh about 150lb, so far I’m feeling very well supported.

First I will admit that I did not place a lot of thought or time into purchasing this mattress foundation. I needed a new one to go with my new bed frame and new mattress I already had. And with it on sale, the price was cheap. I did not notice that this product needed to be assemble when I purchased it. So it was a bit of a surprise to see it come in a long narrow square box. Non the less, after putting together by new bed (, I then assembled this mattress foundation. The instructions could had been a lot more clear. But fortunately you mostly just needed to match up the numbers on the parts. Once I was able to get the thing together, I was very surprised about the quality. The whole thing is sturdy with no weak points that let it move around and bounce which in turn causes the whole bed to vibrate. I can now get on and off of my bed without having the whole thing move and bounce when I do so. My old box spring was made from cheap wood and wire. Also one corner had collapsed and was dipping. It was also a major name brand that cost more when I had bought it. Comparing the two there is absolutely no doubt that the Zinus one is much better quality and will hold up for many years longer then my old one had made it.
