Zinus WonderBoxTM Smart Box Spring, Full, Grey

easy to assemble, great for the price

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. Local retailers were quoting me 2-3 hundred for a traditional box spring. Apparently they aren't commonly used anymore which is the reason stated for the high prices. -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. Update 3/4/26: Still holding up. Haven't had to tighten anything and it's still quiet. Keep in mind though that this is being used for a childs bed but Mom and Dad do spend a fair amount of time getting in and out of it.

Decided to change box spring on bed and wanted something easy to assemble. This item was Purchased based on reviews. Instructions were super easy. Visual instructions which is what I preferred, made assembly less than 40 minutes.

So easy to put together and is very sturdy. Love it!

I purchased this based on reviews. I recently got a memory foam mattress for my guest bedroom and I needed a foundation (box spring) for it. After doing some research this seemed like the best thing to purchase. When I got the box I was a little worried. It seemed like it had way too much tape on it. Was it a return? After opening the box it wasn't a return and everything was there. Maybe the extra tape was for the weight of the box. I looked at the pieces and pictures began to assemble. About 30 minutes later I had a box spring. The hardest part was putting in the screws for the center support. I didn't have my readers with me and seeing the holes was a small task. I put on the snug covering and put on the mattress. I think I'm going to give it a test tonight. If you're on the fence about this go ahead a get it.
