    • Super sturdy and great for a queen size bed
Size: Queen Style Name: 9 inch Design: New Quick Assembly
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!

    • Sturdy metal box frame
Size: Twin Style Name: 7 inch Design: Original
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. ... show more

    • Great Boxspring

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. ... show more

    • Good for guest bed
Size: Full Style Name: 7 inch Design: New Quick Assembly
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.

    • Very sturdy foundation.
Size: King Style Name: 7 inch Design: New Quick Assembly
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.

Very easy to set up, especially if you just place everything where it needs and set it up that way like I did in the pictures. The Ratchet was nice and very handy, happy to have had that and can use it for future use. Fits the frame nice and doesn’t move when getting in and out of the bed

    • Must buy best replacement for box spring
Size: King Style Name: 7 inch Design: New Quick Assembly
After reading good reviews, I decided to go with this metal box spring. The old wooden one was getting weak after a few years and it would squeak non stop. This new box spring was easy to install and it came with the cover. Now my king size bed feels sturdy and doesn't squeak anyone.

    • All HW and Tools.. were definitely NOT included

Review Image by J. S. J. S.
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. ... show more
