Very nice box spring.
I am so glad I purchased this box spring. It was easy to put together and fit my bed frame perfectly. The only trouble I had was the nut had a built in washer. I had to put the nut onto the bolt backwards to tighten it. It worked fine. I know this sounds strange but it may have been just the ones I had. I recommend this box spring. ... show more

Great Value
Color: 6 Inch Size: Queen
I bought this for a spare bedroom because I needed a foundation for a foam style mattress. This metal box spring is exactly what I needed. It feels incredibly sturdy and supportive, and the 6‑inch height is perfect not too tall, not too low. The frame went together quickly, and all the pieces fit tightly without wobbling or squeaking. Once the mattress was on top, everything felt solid and stable. Great value for money and no weird noises. ... show more

The can be used for Storage!
Hands down strong as heck then I thought! I converted mine into a hydraulic under bed storage! I drilled holes in the frame for it and the metal is more then strong enough! Also for converting to storages it has even more room to put you belonging which no one ever keeps in mind! It was super easy to assemble, it does not have cheap chipping paint or thin fragile metal. I didn't realize how unstable and noisy my old box spring was. I definitely sleep 150% better, it made my bed way mode comfy and my bed is perfectly flat! I blew my expectations! -Bed Size: Heavy Queen -Can be converted to under bed storage?: yes if you drill your own holes and got very basic building skill or effort! ... show more

Great Buy!
Color: 4 Inch Size: King
Was a little nervous based on some of the reviews, but I honestly had no problem. The biggest issue was my box had the bottom nearly ripped off so it was tougher carrying inside, but that was it. The instructions were simple, feels very sturdy and wasn’t too hard to put together. You may want to use your own tools to make it easier as the simple Alan wrench is just a little tough if you’re setting it up right into your frame. Also the cover was so easy to put on! Really would buy again. ... show more

Disappointing
Color: 4 Inch Size: Full
Although the assembly of the box spring was much easier than we had anticipated, once put together the dimensions were incorrect. It did not fit inside the bed frame for a full sized bed. Because we had opted for this box spring (assembly required on delivery) over trying to move the existing box spring in our pickup truck for a 9 hour drive to our daughters university; we wound up having to go to a DIY box store to buy plywood and 2x4s to create a platform over the bed frame to lay this on top of. I attached pictures to show how it was too large to fit in the bed frame. ... show more

You have to assemble it from scratch!!!!!
Color: 4 Inch Size: Full
Was not clear to me this had to be completely assembled from scratch. I had no idea a box prong could come in 60 pieces and need to be put together. I literally thought I was getting what was pictured . Was it easy? Ya I guess. Took an hour. But if I could find something for the same price already assembled, I would’ve never bought this. ... show more

Box spring for double size bed
This box spring gaf obviously been opened, put together, taken apart and reboxed. Some if the screws were stripped. There were no instructions, and the boxing was haphazard. However, there were no missing pieces and it was fairly easy to figure out the assembly. It is light enough to move in place and fit the bed frame perfectly. ... show more
