    • 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

    • Straightforward assembly, solid once together
Size: Full Style: 7 inch Pattern Name: New Quick Assembly
After putting this boxspring together, I don't think I'll ever purchase a pre-assembled one ever again! Assembly was pretty easy, and the box has everything you need, including an allen wrench and a small ratchet. The instructions were specific about what order to do things in, but I just laid the parts out on my floor in their correct position, and snapped them together as I worked my way around. The powdercoating on the pieces feels high quality, and I did not notice a single sharp edge or corner. The pieces are all light but quite sturdy. I wanted a solid surface for a memory foam bed, and this seems to fit the bill. Something that worried me a little was whether the metal pieces would clank against each other when everything was assembled, but I think it'll be nice and quiet. The only place that metal could touch metal, there's a thin foam pad to prevent noise. At first I thought the cover was slightly undersized, but after getting all of the corners on, the material on the edges curves up over the top just a little on each side. It looks very nice once the mattress is in place. The ease of breaking this down to move it is a huge selling point. I don't plan on moving again in my life, but a large boxspring is a PAIN to move up and down stairs. This breaks down into a small enough package that you could easily move it up a spiral staircase. I would definitely recommend this to anyone who wants a sturdy base for their mattress, and especially to someone who has a tight pathway to their bedroom. ... show more

    • 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

    • Perfect and easy!
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.
