It’s a good and sturdy box spring for a decent price. I put this together on my own, and found it very easy. It did take me over an hour, but that’s with pauses in between putting it together. It’s also quiet, no noise at all when moving around. I do want to mention that the first set I received was missing a few parts, but I was able to send the first one back and get a new (complete) set a few days later. So don’t be quick to toss the box and packaging before checking to see if all parts are there. (Photo is of underneath box spring with the mattress on top.)

This box spring exceeded our expectations, good quality for a great price! Was super easy to put together. It is very stable, and does not squeak. We immediately felt a difference in firmness on our first night sleep. We have a foam mattress & a bunkie board as well, for reference. Not sure how long the velcro cover will last, but it definitely makes the sides look nice for now. Fit perfectly in our metal bed frame. just fyi: Definitely recommend using a cordless drill with a bit, over the allen wrench they provide (much faster).

Great box spring! I have been sleeping on a mattress on the floor and decided to purchase something quick online. This not only helped my bed look better, but supports the mattress very nicely. I don’t have tons of back pain anymore. It also didn’t take very long to assemble (I would recommend using a drill)

Purchased the queen box spring assembly. 5-star rating for the overall product itself. It is about 59-1/2" wide which sits within a 60" bed frame nicely (your bed frame should typically have a 1/2" lip on each side rail for the box spring to lay upon). Construction seems sturdy, I see no obvious reason it should or would fail structurally, time will tell. 3-star rating for assembly. The premise is simple, however, count on crawling around all over the floor like a kid in order to assemble (not so easy for this old body of mine!) The screws are coated with some kind of blue-vinyl on the threads, making it difficult to thread the nuts on the ends of the screws by hand or even with the useless cheap wrenches supplied. Do yourself a favor right from the start - find a 10mm wrench, and a cordless drill with an allen wrench attachment. It will save you from much displeasure, just do not tighten down all the bolts until everything is assembled. The corner pieces are a complete hassle. I had no less than 3 screw holes that were not threaded properly from factory. I needed to improvise, rethread them. Needless to say, I had choice words for this company by then! Cover is nice material, though it should have a better fastening system than just 2 pieces of velcro. This will NEVER hold over time. Looks good though after assembly, so I split the difference in rating the product and gave it 4-stars.

It seems to be strong for now. Assembling didn’t take much time. I bought king size and it fit my bed frame well. It’s light weight material but strong enough. I would not say it’s a high stability product bcoz when my husband rolls I shake too which is slightly annoying..

Perfect match for mattress. Easy assemble but have to be patient if you don’t like putting stuff together like me. Worth the purchase. Durable. Purchased for 84 yr old das who has high quality taste and back issues. He was very pleased
