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

Bought this for my son’s twin bed. We went from a loft bed and needed a box spring so went with this one, so glad we did! It’s sturdy enough that I feel like if he jumps on his bed it won’t break or anything like wooden box springs can. Super easy to put it together, took me about 20 mins and that was with two kids crawling all over me. The screws were easy to put in and it came with three tools that allow you to pick what’s easiest for you. The directions are pretty simple pictures that show which part goes to which, but it doesn’t take a lot to figure it out. It’s not heavy for meting all metal and the top cover fits snug, it also fits perfecting it a twin frame. There’s also no creak noise when my son got into bed so that’s nice too. Oh and I didn’t have to wash the cover because there was no smell so that was also convenient! Over all 10/10! Might even get one for my cali king, now that I know it’s easy to put together and way more sturdy then the wooden box springs. Definitely going to recommend!

I was hesitant to buy this box spring instead of an actual wooden one. I love it!!!Easy to assemble if you purchase the upgraded one that you can just pop in. I bought two: one twin size and one full size. For the twin size it took me 10mins to assemble, yes, 10mins. I did it alone, so ladies, you don’t need a man to help you! The full size took me 22mins, also alone. The full size does have some screws involved but not many. Both feel sturdy, are not heavy and the cover comes right off so it can be washed. Directions are so simple and easy to follow! Highly recommend it!!!

I would’ve gave this product 5 stars, but I spent 10 minutes trying to place the middle vertical bar that stated UP. However, the yellow sticker on the bar stated up when it should’ve been flipped. Someone was sleeping on the job, but overall the product appears super sturdy and durable! The top part of the middle bars also had a weather strip/nonslip material going on so that the bars weren’t metal rubbing against metal and I loved that feature. The directions were super easy to follow too and I love the fitted box spring protector that was included. I would recommend this product and I would even by it for myself if I didn’t already have one!

This is a sturdy foundation to rest your mattress on; it comes with all the tools needed - and has a Knitted Polyester Cover, similar to a fitted sheet, to put on the "box springs", after it is built.We put it together in minutes - following the *numbered* pieces diagram (that's all it comes with .. no actual words/directions to read).I do wish the Knitted Cover was slightly longer, as we had some difficulty getting it to wrap around all 4 of the corners - the width was acceptable, but we struggled getting it to cover both ends of the CA King bed Foundation.(See photos)We purchased (separately) a full-zip-enclosure to completely encase the "box springs/Foundation".

It took 2 adults over an hour to assemble. We are very well versed in Lego and Ikea instructions and this was a nightmare to put together. Instructions were not clear. If they could put the letters on the pieces it would be a breeze! So far it seems sturdy and like a good value for the money.

I purchased two of the twin xl for my king bed frame, to replace the original box spring’s since my furniture store brand ended up damaged. And I gotta say the savings is real compared to traditional mattress only and furniture stores, the quality of this purchase is above expectations even better than you would think. Added convenience of a washable box spring cover is just remarkable! My only hope is to see additional color selections of the washable cover would seal this deal.

I am a big woman and have a 68lb dog and needed something more withstanding and this is it. It does squeak a bit when moving, but I have faith in it holding up. I was also able to assemble it on my own. It would have been easier with a 2nd person, but was doable.

I love literally climbing into my bed now lol. The height is perfect! This box spring took no time at all for me to assemble and I did it on my own. The instructions were pretty straightforward and after arranging the pieces, it was smooth sailing. No squeaking when I climb in and out of bed (made sure all the screws were as tight as possible). Incredibly sturdy. Im really happy with this!

Easy to install . Seams strong. Time will tell how strong it is.

Product sturdy and light

As most reviewers have said - comes in a very compact package, easy to assemble, good quality.The only problem is that there are no springs. This is not a “box spring”. This is just a box. It performs accordingly.

I returned it last month still haven’t got the refund.

Does its job!
