  • Strong and yet affordable
Size: Queen Style: 7 inch Pattern Name: Original
Had never heard of a box spring that is not made from wood. At first, I was skeptical to order a box spring from steel. My skepticism then got slightly worse when I read some negative reviews about "OHM, it takes too long to assemble!" Being an engineer and an optimist upon reading majority of great reviews, I went ahead and placed an order for queen box spring. Not only it arrived in time but it was also well-packed. It is heavy and you will need 2 people to carry the box from outside to your bedroom. Once I unopened the box, I was surprised to find the individual pieces tied up in groups based where they all go. Every single piece is numbered and lettered. A piece numbered "1" connects to another piece numbered "1", numbered "2" connects with another numbered "2". Very simple and easy. The kit also comes with tools. The part breakdown is as per below: A (inner long rail) = 2 B (inner short rail) = 1 C (outer short rail) = 2 D (outer long rail-1) = 2 E (outer long rail-2) = 2 F (Slats) = 10 S (shortest screws) = 8 M (mid-length screws) = 4 L (long screws) = 2 H (nuts) = 10 The best advice is that open the box, remove the cable ties, lay out all parts on floor as per the intended connection and get an idea of who connects to who (without actually assembling). It is otherwise called a "raw" or a "draft" assembly". Once it is done, it takes 30 minutes MAX to connect all components. I then put the cover on it and zipped it up. Voila, it was now ready to be placed on the bed. The moment of truth was moments away. My daughter and I lifted it up and placed it on her queen bed. It fit perfectly. We then put the mattress and lied down on it. It is very sturdy and does not squeak upon rolling. Overall, it is very strong and affordable. Here is the best part. It can be unassembled and moved to another place much easily (than the traditional wood box spring). I highly recommend it. Buy it with full confidence! ... show more

  • Absolutely silent, excellent construction and easy to assemble
Size: Queen Style: 7 inch Pattern Name: Original
I am impressed with this box-spring. The quality of the build is excellent, and the craftsmanship impressed me. Years ago I delivered furniture, having put together many different types of furniture, beds etc. I have seen some alternative box-springs and whatnot, but this takes the cake. Unlike a traditional box-spring made with wood, this is not going to wear down over time and squeak due to the grip of the nails in the wood (a common issue with squeaking in construction). First, assembly took me about 20 minutes, and I didn't even need the instructions. I was able to put this together easily by myself and move it by myself as well.The parts are marked "up" conveniently where you might go astray in the build, and it stays together well enough before adding the bolts/nuts so that one person can do it alone, provided you do it on a flat surface such as the floor. I love that this boxspring can come apart too, if anyone needs to get it into a tight area (the worst part of a bed delivery, imo is the box-spring as it cannot bend/fold). I have gone from a two part box spring for a queen mattress down to this and it makes NO sound whatsoever. Craftsmanship is excellent, and the parts fit together like a glove. The "slats" are not attached by screws, rather just sitting in place, but they are wedged in place and do not move out of place. Only weak spot I thought of was having the zipper face down so that the zipper part of it sits on frame (thus possibly cracking the zipper or its mechanism) but the zipper comes toward the center of the box-spring far enough to clear the side boards of my bed, so I will have to see if the zipper takes damage over time from the downward pressure. Certainly not going to knock anything for that. Edit: Dec 1, 2017: This is still absolutely quiet and no squeaks at all over the past couple months. Really highly recommend this box spring to anyone looking for a lifelong keeper. Edit: July, 2019: Still a perfect boxspring! Edit: July 2024: Still a perfect boxspring! ... show more

  • Totally awesome - bed foundation
Size: Queen Style: 7 inch Pattern Name: Original
This is the only way to buy a box spring. This was so easy to assemble. The instructions make it totally simple. The parts are numbered, you lay it all out, and then literally start assembling in numerical order. The fitted cover slips on over the top and it is ready to put the mattress on. If I ever need a box spring or know someone that does I will recommend this assemble yourself box spring. It was fun to put together, great quality, sturdy. A cute little thing they do that is really smart - they include a thank you and a Hello you card that is blank inside so you can now use them to send onto someone. As they said they hate to be wasteful so they say hello you and thank you but the cards are there for you to use now. Yes - you still need a bed frame for under this box spring and a mattress for on top - I am including this comment because I have had people ask me! LOL I did not read on the slip on cover if it is washable but I would assume it is which is another bonus should you ever have an episode of critters or any other reason you may want to wash this - regular foundations do not offer that option. I bought this for an older gentleman and already put it at his house so can not read the label on the cover now. YES - I would recommend this to anyone ... show more
