  • Best brand we've used!
Size: King Style: Box Spring (Original)
After owning for 2 years I'm ready to leave a review. No issues putting it together. Easy and done quickly, by myself. This frame put together, made a trip from OH to OK, with no issue. On 2/14/2025 we got a new frame, due to needing something higher(same brand). This frame was still sound, no squeaking, bolts never loosened, no bending in the frame anywhere! We are NOT SMALL people. He's 6'2 near 300 and I'm 5'2 and about 210. This brand has never failed us. All of our beds and mattresses have been from them. ... show more

  • Easy Assembly, Great Quality, and a Fantastic Value!
Size: Twin Style: Box Spring (Original)
I was pleasantly surprised by how well-designed this product is. Often, with items like this, you struggle to make the pieces fit, but everything here aligned perfectly. The crossbars were a little snug, but a quick tap with a rubber mallet got them into place easily. The instructions were clear and straightforward, making assembly a breeze. It even came with three wrenches, which was a thoughtful touch! The materials feel durable and high-quality, so I expect this to hold up well over time. Overall, a great value for the price—I highly recommend it! ... show more

  • Pleasantly surprised....so far...Update ....30 JAN 2021...
Size: Full Style: Box Spring (Original)
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... ... show more

  • A solid bargain.
Size: Queen Style: Box Spring (New Easy Assembly)
Was easy to assemble, sturdy, lightweight and a great price. Can't go wrong if you want some rigidity and height on a bed for your mattress.

  • Best Box Spring Ever!
Size: Queen Style: Box Spring (Original)
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. ... show more
