Box springs can vary greatly in price, and I was looking for a reasonable priced one. When I saw this one I decided to give it a try; and I was very happy with the results. he box springs come unassembled and include the tools needed to assemble it. Assembly was quick and easy, and the cover went on with no difficulty. The final product was very sturdy and comparable to much more expensive box springs. One thing I liked was it is relatively light weight, if a bit bulky, so I could lift it and put it in th ebed by myself. The only problem I had was some of teh cross bars came loose while I put it in place, since teh drop in and are not screwed down, but they were easily put back in place. In use it provides a good stable base for a mattress. Overall, I think this is a great value at the price and recommend it to anyone looking for a good sturdy box spring. Review: Super Solid Frame at Reduced Height That Feels Super Stable! - Update 4/21/2025: Just wanted to give a "final" update that things are still working well and I'm sleeping better than ever without any worries. I can jump on to the bed without ever feeling like something will break or cave in and can wholeheartedly recommend this if you are just looking for a solid foundation vs the traditional wood box spring. I have 0 issues with the mattress above this foundation slipping as well, which was a problem with my old box spring. This review will likely no longer get any updates unless I encounter any issues Update 12/3/2024: The frame has remained solid and I've slept better than before and have 0 concerns with durability so far. I also liked that it is shorter than my previous 9 inch box spring and is easier to get on and off the bed since it is lower to the ground. Also, previously my mattress had a huge dip where I laid on it due to the broken box spring caving in the mattress along with it, but I'm happy to report that it is now almost flat and you pretty much can't tell that it was ever caved in before, almost as soon as I laid the mattress down on the new foundation. One thing I noticed is that it is not exactly "no noise". I don't hear any noise when I'm laying on the bed or with minor movements, but I do hear noise if I jump on the bed or "rock the bed" so to speak. This isn't an issue with me, but do beware if you are looking for a no noise solution, this may not be it for you. However, if you are just looking for a super durable mattress foundation, I still wholeheartedly recommend it. ---------------------------------------------------------------- Everything is in the box and the instructions are simple and very easy (it's not complicated to put together to begin with). Lifting up my mattress to replace the box spring was the hardest part. There's not a lot of screws (though they are all hex screws), so the instructions are more than good enough and the cover slips on really easy too. Be prepared for some lifting and make sure to have plenty of time and space though. I barely have any space in my room and I had to assemble most of it over my bed before standing it up and dismantling the bed. The process will go a lot faster if you have your own tools, but the tool included does the job ok. Once built, it feels super sturdy. There's not a lot of springiness since there's no springs, so if you don't like a stiffer bed to lay on, you might prefer traditional box spring, but the full metal construction of this does feel more solid and feels like it'll last waaay longer. The lower height also is nice when getting out of bed. I will report back if durability becomes a problem, but right now it doesn't feel like that will be an issue ## Features - Box Springs Sturdy Construction: Heavy duty metal slats and durable reinforced steel construction that resists wear and tear.

Sturdy and easy to build. We got a used one so it didn’t have the instructions manual but my husband managed to build it without out it.
