    • Good value easy to assemble box spring
Size: Twin Color: 5 Inch
I needed a box spring for a Little Tykes race car bed. 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. ... show more

    • Sturdy, Easy to Assemble, and Great Value

I’m very happy with this bed frame. It was easy to assemble, and all the parts were included with clear instructions. The frame feels very sturdy and doesn’t squeak or wobble, even after regular use. It provides excellent support for the mattress, and the extra space underneath is perfect for storage.

    • Super Solid Frame at Reduced Height That Feels Super Stable!
Size: Queen Color: 5 Inch
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 ... show more

    • No support underneath. Slips. Save your money.
Size: King Color: 5 Inch
I honestly hate writing bad reviews, but this box spring has way too many misleading “positive” reviews. First, assembly was annoying even with the instructions. We get a lot of our stuff from online. So, we are used to putting things together. This wasn’t particularly “difficult”, just annoying. Second, stop saying it is non slip. MANY people have stated (even in the positive reviews) that this box spring slips. Not only does it slip, but it has ruined my king size bed frame on the bottom right corner. There should be some sort of non slip on the underside of this thing. Even if it is just plastic covers over the corners. When it slips to the left or right the box spring (because it is fully open on the underside with the exception of one metal piece down the middle) the box spring drops over the lip of my frame and has now ruined the material on my brand new bed frame. I bought a $100 bunkie board that I haven’t received yet, but I should have to spend more money on the support than I did on the daggon box spring. It makes no sense. Not when it is advertised as “No Slip”. I hate the engineering of this thing. I don’t believe that any good engineer came up with this. In fact I believe that they were open and honest about what would happen if they cut corners and they did it anyway. DO NOT BUY THIS! Go to a store or keep looking around online for something with support on both sides of the box spring. ... show more

    • Not as good as expected
Size: Queen Color: 5 Inch
This was fine once we got it put together. I dislike putting things together! After a few months, it started to come apart. I have no idea how or why. The direction the screws go in isn't conducive to them coming out. We've lost one of the support bars. I won't buy this again.
