The box spring in a guest bedroom was creaking badly and I didn’t want to spend a ton of money to replace it. When I found this option, I thought I’d give it a try. I am a 71 yr old female and I put the frame together in about 10 minutes - super easy with clear instructions. The cover was also easy to put on and zip up. I like the way the slats are metal - 10 of them are used making the base sturdy, but light enough that my husband and I could easily move it into place. It fit perfectly on my queen bed frame and with the mattress it is very comfortable and no creaking! I can’t speak to its longevity since it is in a guest bedroom that is only used several times throughout the year. But so far it has been perfect for what I need.

Well made fairly easy to put together by one person but pulling the way too small cover takes 30 minutes so you do not rip it as a few reviews indicated. It goes on easy once you have to figure it out from the horrible directions no words in english. Turning the last corner the fabric is 5 inches to short you have pull hard from other areas to work it to get it over the last corner at the same time you have to be careful not to rip it or the thin zipper off . If they made the cover a few inches bigger you still could get the frim fit without the ridiculous hassell of pulling it hard.

Wow! I’m impressed. Never thought I’d get a box spring in a box and it’s sturdy. Took about 10min to put together. Didn’t even need any tools. Very good quality. I would buy again!

I really love this product.. it was no tools needed everything snap together and I did it all by myself lol. After receiving one from a company that was damaged, ordering the Amazon basics metal box spring which was so much easier to put together and it was boxed up with care... this one is very good quality and sturdy.

2 small girls share this bed,. 1 is 120 lbs, the other is 100lbs. We purchased a new mattress and this box support 4 months ago for the existing queen frame in their room. we also were replacing the traditional spring mattress with a hybrid so we changed support style to steel slat box to give firmer coverage to the mattress design as recommended by the mattress mfr. If you look at the 3rd photo in the ad, where the steel frame is being assembled by a hand inserting 1 of the rods, you can catch an inward curve of the side of the outer rails both upper and lower edge. This true on mine as well and ended up becoming the 1st issue. the corners measured fine and went to the proper measurement for our queen base, and sit perfectly square on the bed frame, but the middle on 1 side rolls inward, narrowest was a full centimeter narrower than the corners. This got worse over time and eventually let the box slip off the frame when it began to flex the 2nd or 3rd month we had it in use (after the 30 day return had ended). I eventually remeasured, and yes it had lost several more millimeters from flexing. So I ended up bending the frame of the bed on the side to give additional support. That helped for a couple of months. yesterday, 1 corner of the bed dropped 4 inches or so from the corner to the middle of the bed, the other 3 stayed at height. one of the girls was sitting on that corner putting on her boots and it just suddenly DROPPED she said. I flipped up the mattress and removed the box cover. The upper and lower rails of the frame are pre-made with support ribs every foot or so to give it strength and maintain rigidity. 3 of the bars on the collapsed corner had broken their spot welds, and the cause of this was the premade corner joint metal had flexed and broken and you can see the weld was poor so the corner was weak and eventually gave way. This is not due to excess weight, or kids playing bounce games on the bed. It was used by 2 slender teenage sisters with a total weight of 220 lbs, the frame is rated at over 600. The only reason this happened is the welds could not withstand the on and off application of weight and flexed till they broke. since the corner holds the angle and shape integrity, once it broke the supports ribs then had to absorb the now moving rail spacing and eventually their welds cracked. Steel that is rated over 600lbs needs to be durable enough to hold 220 lbs forever, not measured to not collapse with 600 for 10 seconds and then claim "Hold 600 lbs!". Less than 225 lbs over 4 months bent it more which should not happen even if it started slightly curved, it bent more over time because the weak metal flexed stressing the weld joints till they physically cracked likely 1 at a time. It simply isnt a sturdy or high quality piece. It was curved when it arrived. I addressed that by making the frame cirve to make sure it didnt have a less supported rail on 1 side. The 2 months later the welds cracked on 1 corner. I dont even want to warranty it after seeing how it failed. , I expect the same issues will repeat. I assembled it myself, and noticed the slight curve even when I put it together. but the bed frame still had a grip on the box enough it looked like it wasnt perfect but should manage. I liked the high star rating which is why I bought it. Thousands of purchases. However I am a mechanic by trade, with a welding certification and 30 years experience. I do not want this frame again. It has inherent weaknesses in its construction quality that wont affect it for everyone when new, but will make it fail earlier than needed even if you get a better one than the defective one I apparently got. You get what you pay for. There is a reason this box support is 100 dollars cheaper than many of its competitors.
