I was especially surprised that both split-king box springs came in one box. The bed frame was easy to put together and the box springs were even easier to unfold. I find myself going to bed early every night now that I have my new bed. Thank you Zinus!

I love this box spring! I got the 4” for my queen bed and it’s much quieter than the bunkie board I was using before. As a matter of fact, it doesn’t make a sound. My bed is much for stable and comfortable because of it. I will be replacing my son’ bunkie board with a Zinus box spring within the next few weeks. Assembly (or lack thereof) was also a breeze - simply unfold and place the cover on!

So many mixed reviews about this product. I honestly was nervous ordering it. But after such terrible service and false delivery promises by brick and mortar mattress stores, I hit the internet. I ordered the folding frame and the 12" queen green tea mattress. The boxes were promptly delivered (I received the boxes 3 days after ordering) via FedEx. I did have to enlist the help of a friend to get the boxes not only into the front door but up some stairs. The boxes are heavy and large. However unpacking and setting up were a one woman job and I was able to set up on my own. I have no idea the sorcery that goes into the folding frame. With a quick unfold and a zip up it was ready to go. The mattress was also a quick release from its plastic wrap. I left the mattress alone for 2 days before putting bedding on it and sleeping on it. The mattress reached its full 12" the same day as unpacking it. NOTE OF FULL DISCLOSURE for future buyers: I am only 2 weeks into sleeping on the bed and mattress, but these 2 weeks have been excellent! So comfortable! My first impression was that it was too firm for a back sleeper like myself, but that is not the case. I really hope these products last several years. So far so good and I have no regrets!

The box springs were easy to get in the house, up the stairs, unpacked, and folded open. Work very well, stable, rigid, and the fabric cover makes them look like real box springs from the outside even though it’s steel tubing on the inside. Very satisfied.

Im just waiting for the week to be up so I can try to get another one sent. My 12 inch pressure relief green tea mattress is 10 inches at best the corners are curled up and the smell is nauseating. I have aired it out as best as I can but the smell is still there. I have to change my sheets every day cause it sticks to them. My whole room smells sickening. I'd like to give it another try and fingers crossed I can get the one that other people have reviewed with no or little smell and original shape and size..

We bought our second mattress because we upgraded from a queen to a king. This time we added the box spring to our purchase and it’s one of the best decisions we’ve ever made. This mattress is comfortable, the box spring is heavy duty, and we are going to be Zinus customers for a long time. We could not be happier.

I bought the 4" folding box springs so that I could lift my 14" combo mattress out of the sleigh bed well. Before, I couldn't make the bed very well. It's perfect, just high enough. I was worried that when it came out of the box & plastic, that it would snap open, not constructed that way. It gently unfolds (you have to push it apart) and then you zip up the cover. I did a queen size all by myself. I have a bunkie board underneath it, so I actually put the folded box springs on that before I opened it.

Every box spring should be made like this. The old-style one-piece box springs are garbage compared to this one, especially if you have an L-shaped stair, winder, or any other spatial challenge. I just bought this for my older daugther's room, and though my younger daughter has a relatively new box spring (under a Zinus mattress) I'm even considering replacing her box spring since it's ridiculously loud (just getting in & out it squeaks something fierce). If you have any sort of curve in your layout or tight space this box spring will outperform the conventional styles we used to settle for- if you don't have these challenges, get this anyway as it will still make your life easier than dealing with the traditional behemoth.

With the newest mattresses that are not made to go with traditional box springs, this product bridges the gap and offers a well made and easy to install substitute. If you have a traditional bed frame, you still need something in place of the box springs and this works perfectly!! Shipped quickly in a box that is manageable, even with a king size that we purchased. Easy to move into the bedroom where it was installed easily and without any hassle.

After adding the Zinus boxspring, our mattress felt much more firm and supported. Besides putting us at the right height so our pillows would not get wedged between the mattress and headboard, we slept much better than just with the mattress by itself. It was fairly easy to unfold and get onto bed frame with one person.
