Amazon Basics Sturdy Smart Box Spring Bed Base, 5-Inch Height Mattress Foundation, Strong Support for All Mattress Types, Tool-Free Easy Assembly, Twin, 74" x 38" x 5", White

I have purchased three different box frames in the past, and this Amazon-branded product is miles better than the competition. The superiority of this frame comes down to two main factors: Smart Engineering: The design is practical and highly efficient, making the assembly process simple and straightforward without compromising the structural integrity. Build Quality: The materials and construction make this a definitive 5/5 product. It easily outperforms other models on the market. Well done, Amazon. Highly recommended.

Just what I needed! I didn’t want to pay 250 From the local mattress store for a low profile box spring so I decided to give this a try. A great alternative. Seems sturdy and was very easy to put together. Everything snaps in and it’s so intuitive you don’t really need directions. One of the corners was bent up so it gave us some trouble fitting in one piece but my husband was able to take the back of a hammer and straighten it out, otherwise I would have had to get an exchange. I would recommend.

This is an interesting box spring; it is not like a regular one that I have seen before. Most come like you see them complete and in the final shape and dimensions, but this one comes apart in a rectangular box about 5 ft high. and approx 9X9 around. You open the box and pull out the internal frame. Most of it is folded up and condensed into a smaller package, there are also bars that will be used to assemble and a cover. You basically open up the main part, add the ends and connect them. No tools are needed. after the outer frame is done there are 4 hand screws for the corners. then you just pop in the bars and it is done in the shape of a box frame. Then you open the cover and place it on the frame like making a bed with a fitted sheet. Lift it up and zip the bottom closed like a bag around the frame. then move into place. It is very sturdy after completion and lightweight. It spanned the frame well and held the queen bed mattress. I would recommend this frame for any size. Is light, strong and easy to use and move.

Made of pretty sturdy metal so I think it will work well long term. Was easy to asssemble. I am 59 and was able to put it together myself. I took away one star because the cover does NOT fit very well. My husband had to help me try to stretch it over the frame and the zipper def gave way on one corner. Also, as other noted, it is slightly small. It does not matter as it rests on the bed slats just fine. But, I would have preferred the cover to fit and the size to be just a smidge bigger. But, for the price, it is good and sturdy and that is what matters.

Seems to be a good box spring and easy installation. I will come back when get the right size for more details. Unclear on the sturdiness at this time due to wrong size.

I was looking for a 5 inch box spring option, and I couldn't bring myself to spend $300 on one. I did some research and thought a metal box spring would do the trick, and at $100 and 2-day shipping, this fit the bill. I was able to easily put together the queen size option all by myself as a petite lady in less than 30 minutes. I had no problems with pieces not fitting together properly. I also had no issues with the cover. It is meant to be snug. As of now, I'm giving it five stars, but may adjust as needed later. The only thing concerning to me are the hinged joints on the side rails. While there are only two, they are definitely the weak point. If they don't fail, this will be a great find.

This 5 inch bed base was perfect for our new king-size bed! We had previously purchased a 9 inch and it made the bed way too high off the floor. We replaced it with this nice one, it came ready to assemble very easily – the pieces were clearly marked and it only took a few moments to snap it together. Nice quality.The cloth fabric covering made it finished. Highly recommend!

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.

best Spring box you can buy

It was very easy to put together. You don’t need any tools. Wr organized it on our living room floor and then carried the frame up the stairs to the bedroom, without the 10 crossbars in place. It was lighter and we didn’t want them falling out. A couple of thr crossbars were hard to put it. One of them my husband had to take the little “insert” out of the end to get it to fit. Thr most difficult part was the cover. It has to be tight but it’s quite difficult to get the last corner in. We kept zipping it up and the zipper came apart. In the end we both pulled in the fabric and the corner fabric popped into place and the cover fits perfectly. I think it would need two people to get the cover on. It makes the box spring look professional. Very good quality. I would recommend it.
