  • Works great!
Color: 9 Inches Size: Twin
This took me about an hour to assemble by my self. I cleaned all the parts and made sure all the pieces would fit and screw in properly before starting so assembly its self took more like 45 minutes to complete. I got the twin size and it fit my twin bed frame perfectly. None of the parts squeak or creak. It's solid and Generally well made. The cloth cover fit over it all just fine. there was one issue, though. Since the metal frame was sitting in metal, it could slide back and forth on the metal frame with a a bit of a nudge which is not idea. EASY FIX: I knew this would happen so had some rubbery self liner near by.. I cut some long pieces and places them under the frame in some key areas and bang! it does not slide at all even with a strong shove or pull. Problem solved. It's a little bit taller than a typical wooden box frame so my bed sits a few inches taller but its not that big of a deal. My mattress needs replacing for sure but with this new very solid box frame, it is way more comfortable and supportive that it was on my old wooden, creaky box frame. and IF the new box frame does get squeaky I can use WD40 to fix it right up. And it's waaaay easier if I had to move. Just take it apart and shabam! it's a go with some ties and a bag for the parts. This kind of metal frame is definitely an improvement over a wooden box frame any day. 4 and not 5 stares because it was a beast to carry from the post office. yes, I carried this bad boy quite a ways and it was super gnarly to do so since the center of gravity of box was wonky and it was pretty heavy. Definitional a two person box to carry for sure. ... show more

  • Very happy withy purchase!
Color: 9 Inches Size: Queen
This fit my bed frame perfectly. Easy to assemble (instructions included, but didn't need). A power drill set to the right torque cut assembly time in half. I built the main outer assembly first, then placed the main assembly onto my bed frame -this made positioning easier and lighter for a one-man job. Afterwards, I set in all the structural ribs to completion and slid the mattress on top. Easy-peasy! ... show more

  • Best box spring

Love these for my kids; It’s strong and better than the wood box frame ,that my son broke with easily by jumping on his bed. This one doesn’t budge when the kids jump on .

  • Box springs
Color: Split 5 Inches Size: Twin
super easy to assemble. Sturdy, worth the money. Comfortable and very supportive. Only downside is that the smaller middle bars to slip out if sat on its side during moving. Best to keep in flat.
