Zinus5 Inch WonderBox(TM) Smart Box Spring, Quick Assembly Mattress Foundation, Durable Metal Frame, Twin, Grey

Brilliant! Excellent way to buy a sturdy, easy to put together “box spring” (5 mins)!

Although mine did not come with instructions, it was pretty self explanatory. It does not look the best and is okay quality. Serves its purpose. Mine had extra parts. It is not very versatile. Easy to move and assemble.

I recently ordered this frame for my son’s new bed. I arrived with no damage and well packaged. It does require some assembly with an Allen wrench, some bolts, and washers; however the directions are self explanatory enough and I was able to assemble it within 15 minutes. It also conveniently comes with a torque wrench for the bolts which made it a lot easier versus using the metal allen key. It also comes with extra bolts and washers in case you misplace some. The height was also perfect at the exact 7” I needed. All in all, a great purchase.

Easy to assemble except two pieces were missing. I tried to call the company for replacement but they wanted pictures, etc. instead I returned (very heavy) and was sent a new on. Good height, heavy duty, no squeeking and good price.

It was easy to set up (less than an hour) the instructions were easy to follow! It's also very study to sleep on. Strongly recommend this product!

I received this queen boxspring yesterday and I really like it. I put it together alone in about 30 minutes and it was very easy to assemble. It is light weight and supports my mattress perfectly. I am very happy with my purchase and I would recommend this to anyone looking for a boxspring. It was cheaper than what I was planning on purchasing from the store here in town and I didn't have to worry about how I was going to get it home.

We purchased this foundation to get our memory foam mattress to a better height inside the bedframe. This certainly did the trick and it is very well constructed, easy assembly and after sleeping on it for a week, it has not made not one sound. Would definitely purchase again.

Zinus was a complete failure today. I have bought 2 of their mattresses and we love them. This product unfortunately didn't arrive with any parts and the Zinus Customer Service who was not much of a help in getting me the replacement HW quickly. I am surprised that they haven't made provision for this type of situation since I am sure it happens reqularly.Ok - so here's Part 2 of this review. I wish there is a ZERO star. So not sure who did the QA for this one box that I received but in the words of my kids - this was an EPIC fail.To continue this saga, when the box arrived, much to my dismay, the hardware was not included. So while zinus support was of ZERO help - despite this being a frequent occurance with their box springs (just search the comments and you can check), Amazon shipped me a 2nd order of box spring which arrived today - 3 days after the 1st one. So I was all set to just put it all together coz now I have all the screws and boths.Ummmm.. can you tell the difference between the 2 pictures ?? It appears Zinus folks, forgot to make the 2 holes they needed to make on the piece. So now, i had to dive back into the box (of course I had taped it back up to go back to Amaraon) that arrived today, and along with the hardwar pouch, had to go and find the piece and make sure it has the 2 holes.Who forgets parts these days ? I mean are you using your aunts and uncles to do QC Zinus ? I thought most manufacturers used those new fangled things called 'computers' to make sure the correct Bill of Material is INCLUDED with the box, before it is sealed ?? You guys make a good foam mattress and that's just 1 item.. and i thisnk you should stick with just 1 item to pack. Anytime it semms more than 1 item, like this boxspring - you guys just can't do it. Not a biggie - we should alll do what we are good at.

Instructions were easy to follow and the pieces fit together like they were supposed to, had absolutely no problems constructing it. We could not find a California king box spring or foundation anywhere close to home so we are thrilled Amazon had this option. The bed makes no noise now when we move around and it feels incredibly solid. Seems sturdy, like it is going to last and with the new frame our mattress (purchased almost two years ago but still fairly new) feels AMAZING!! My husband and I just had the best sleep we've had in so long. What a significant difference, we both woke up with no pain for the first time in memory and feel like a million bucks. Overall this purchase was well worth every cent! Thanks Zinus and Amazon!

Initially intended to buy the 5” version but was sold out. This one is perfect under our new king size Casper mattress. Assembly was easy, you just need space to lay it all out. No squeaking or noise which was what we were afraid of.

Just built it the day before yesterday, it's a nice product to be fair, but what I received is a returned one, those cable ties already cut open, that’s one star lost, but others are fine, it’s not hard to assemble the pieces together, the fact is it’s tricky in the fist steps, after that it’s easy.it does take around 40mins.

This came in a fairly small box, easy to move without help. It took my husband and I approximately 20 minutes to assemble with the provided tools, it's pretty much idiot proof even without the directions (which are very straight forward). The only issue that we ran into was user error. Because the slats just set into the frame and do not actually attach, when we lifted it slightly to get the mattress cover onto the assembled product, the slat I was holding slipped out and the boxspring fell on the top of my foot (and was heavy enough to break the bones). Love the box spring, just wish I had used my brain a bit when moving it around.

This is a easy to assemble metal framed mattress support frame, or box spring (there is no spring in it). This was assembled easily in a few minutes and I was able to carry it upstairs to the room without trouble. The cover wrap worked well and the frame is solid. I would recommend this if I am looking for a box spring.
