ZINUS9 Inch WonderBox(TM) Smart Box Spring, Quick Assembly Mattress Foundation, Durable Metal Frame, King, Grey

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.

Durable. Easy to put together. Doesn't squeak when getting in and out of bed or while moving around on bed. I'd recommend to anyone looking for a quick easy set up at affordable price

I spent a ridiculous amount of time comparing prices and features before ending up with this purchase and I am so glad I did! Everything is perfect, all the parts, the fit, the engineering, even the finished look. Easy to put together with snap lock connectors. I have a relatively thin mattress and still can't feel the crossbars through it. This is day one. All the negative comments about bed foundations from other sellers don't seem to apply here. As for durability, my expectations are high but we'll have to wait and see.

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.

Super easy to put together, just align and click. There were 8 bolts to install, but it came with nice little ratchet hex key that made that easy as well.

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.
