ZINUS 9 Inch Metal Smart Box Spring, Mattress Foundation, Strong Metal Frame, Easy Assembly, King

The instructions for assembly and the assembly itself is similar to IKEA products. This box spring (original) arrived last evening and I've put it together this morning. Putting all of it together on your own until you have it set up for use takes a little over an hour. It would have been good if the box spring's cloth cover covered the under side as well, so you didn't have to clear up dust more often. I needed this box spring to add some height to my whole bed setup to get in and out of bed easily. It works!

Yes, the directions are basic, but honestly it was super easy to follow and put together. I read other reviews that speak to squeaks, and because of that I used the included wrench to REALLY tighten down every screw. I jumped around my bed afterward and NO SQUEAKS! I love this concept of a king box spring that is light, easy to maneuver and it fit great in my frame.

Very easy to put together and feels very sturdy. My mattress actually feels like it’s gained back some firmness. I credit the middle bar in the frame. My old one ran top to bottom but this one goes across.

First of all, I was pleasantly surprised with the quality of this box spring. Only one night sleeping on it but no squeaks so far. I should add that I will update this review if any problem occurs.Before I ordered this, I read through all of the questions and answers which took a couple of hours. So glad that I did as several customers mentioned the cover and problems putting it on. It is a very tight fit but if I can do it at my age, anyone can do it. A suggestion to the manufacturer would be to add perhaps 1/4 to 1/2 inch more fabric and it would not be so difficult to place over the box spring.I also watched the video twice before I ordered this and that was easy to follow. Four of the pieces were labeled with a yellow sticky that said 'up' which was most useful. My other suggestion would be to label all of the pieces with 'A, B, C, D etc. which would have decreased my assembly time by at least one hour. I did go back and watch the video again while I was assembling.Total time for me to get the pieces in the right order, double-check the placement, tightening of the hardware, etc, was 4 hours. After I got the box spring assembled, I went around each piece and put pressure on each one, to make sure things were as tight as I could get them. I am visually impaired so perhaps that contributed to the amount of time it took me to assemble it.At my age, I am thinking that perhaps I should have had someone make sure I had everything tightened well. If anything loosens up over time, will have someone help tighten it for me.All in all, so far and so good. The mattress I have on top is really heavy and as I stated previously, the box spring has no squeaks and appears to be most durable. In other words, no movement of the box spring.Update to follow if anything should occur.Edit on 26 MAR 2019... Have been using this for 17 months now... No squeaks, absolutely zero problems! Still as satisfied as the day i first reviewed this in October of 2017. And, my recommendation is still that I highly recommend this box spring.Update on 10 OCT 2019.... The 2 year anniversary of this box spring and once again there are no squeaks and zero problems. Still highly recommend this box spring~Update as of 30 JAN 2021...Absolutely still in perfect condition. Was going to increase the star rating to 5 but don't dare to change it. Truly outstanding and most highly recommend this item for everyone that wants a sturdy and long-lasting box spring. Could not be any more pleased with a product...Most highly recommend...

Wow! Couldn’t be easier to put together. All parts easily snap together. Took less than 10 minutes including looking at instructions. Very sturdy. Will be easy to disassemble when necessary. Originally ordered Amazon version but the promised shipping date kept getting pushed out. This was actually less expensive. Couldn’t be happier.

I was really surprised how easy it was to put this together. I was really worried when I saw the box of all the pieces but there are only six screws as most of the pieces are held together with those pop out metal buttons. With a cover on it looks good and seems to work well!

I'm impressed with this platform. It was very easy assemble and is sturdy. It also fits in my full bed frame perfectly. As a bonus, it came with a hex socket wrench. Very happy with this purchase!!
