    • Perfect solution for box
Size: Full Style: 5 inch Pattern Name: New Quick Assembly
We got a new bed frame for my young teen son which required a box spring mattress. I was not looking forward to having another giant mattress to drag upstairs. This frame was the perfect solution at a great price. The delivery box wasn't too big (compared to a full-sized mattress), and it was pretty easy to put together in just a few minutes. It seems to be pretty sturdy. I also like that it came with a fabric cover, although, it did have a small tear which won't even be noticeable with the main mattress on top. ... show more

    • Effortless Assembly and Rock-Solid Support – A Huge Improvement Over Older Models
Size: California King Style: 7 inch Pattern Name: New Quick Assembly
I’m really impressed with how far assemble-at-home box springs have come. I bought this California King size box spring and couldn’t be happier with the experience. Setup was incredibly easy—everything fit together perfectly, and I had it fully assembled in under 30 minutes without any frustration. It feels solid and well-built, offering great support for the mattress. The last time I assembled a box spring at home was back in 2018, and that one was a struggle from start to finish. This one was the complete opposite—quick, intuitive, and sturdy. Highly recommend if you're looking for a hassle-free option that doesn't compromise on quality. ... show more

    • Highly recommend. Sturdy
Size: King Style: 9 inch Pattern Name: New Quick Assembly
While easy to assemble the pictures in the instructions didn't fully explain how to put together. Very sturdy and would buy again as it is light enough and if moving you could take apart to avoid the hassle of trying to navigate through tight corners.

    • First Impressions
Size: Full Style: 9 inch Pattern Name: New Quick Assembly
The Positives: -It was pretty simple to assemble (or would have been see cons). Just 6 screws. Straightforward instructions. Minimal parts to connect. -It feels solid with two adults and a child in it. -Not Noisy so far. Silent in fact. I was concerned about it being noisy so I added electrical tape at all metal to metal contact points. Particularly the end of the cross braces. This made things fit tighter and there shouldn't be any metal rubbing together now. Can't say this made the difference but it is quiet. -Price -The cover was easy to fit. It's basically just a fitted bed sheet. Cons: -No surprise, the metal is the typical cheap Chinese pot metal. -The machining for one of 6 screw holes was missing most of it's threads. This made it impossible to assemble using the screws provided. Thankfully I had a box of nuts and bolts and was able to complete the assembly without the screw. -Two of the cross braces didn't have the plastic grommet in the end of them. This would have meant extra metal to metal contact. I remedied this by fashioning my own grommet out of furniture foot pads. I shouldn't have needed to do this but I'm sure it will work better now anyway. Tip: Use electrical tape at all metal to metal contact points to avoid noisy metal to metal friction. This was at the end of cross braces and then the center contact point where 4 screws are connected. Summary: It was a very cheap solution that seems to solve the problem. If you don't have a little Macgyver ability you might want to avoid this. The quality of the material and machining matches the price. Ease of assembly with simple instructions is a plus. Will update if the thing falls apart. ... show more

Size: Twin Style: 5 inch Pattern Name: New Quick Assembly
I bought two twins and they are awesome! Super easy to put together. Very lightweight. I assembled them in a larger room and carried them by myself to the room where they fit the beds. When needed they can be easily disassembled.

If I could give this zero stars I would. Not particularly easy to assemble since everything came unlabeled, the directions just a couple pictures, but I figured it out. Purchased it to make my new bed firmer which it did do! But it does slide around a bit, annoying but again no big deal, I would just slide it back in place and planned on putting down rubber strips or something to help it grip. The issue: Occasionally when rolling over I heard a pop and worried something was breaking and woke up today with the corner of my mattress sinking. I pulled the bed off and realized a lot of the slats had come loose and the bed was sinking inside the frame. The slats aren’t long enough to meet all the way inside their little holders and every time the frame shifts they pop out of place. The four outside sides aren’t screwed in so they can be pulled slightly apart and they just pop right out. Seems like it wouldn’t be a big deal, but since it slides around on my frame it keeps popping out. Also the plastic joints holding the two middle pieces together have a small plastic piece holding it on, so no matter how you place it the weight of the mattress slightly off the frame pops it out of place and that is also contributing to the issue with the slats. Seems dangerous and bad for your mattress. I’m super frustrated with how this turned out and now I’m going to have figure out how to disassemble the whole thing and return it somehow. See pictures for a better explanation. ... show more

Highly recommend this for a quick, durable and transportable box spring. It was so easy to assemble. We used for college kid moving and we were unable to transport a typical box spring due to size. Will be getting my other kid one too!!
