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!

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.

Great product at a great price. I now have two of them, one in cal king and one in queen. Both are performing well. Note: When you set one of these up, make sure there is another person around to help with the unpack and the unfold. And follow the instructions!

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.

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..

It unfolds easy but no instruction how to fold back up. I am returning because it is not exactly box springs. I bought the twin size. It just gets the mattress off the floor. I wasn't going to use it for permanent use. Just for grandchildren visits and wanted to be able to store it. It was a fail for me but I can see where it can save people money. I just need instructions how to fold it back.

I just received my 5 in bifold full size box spring, however I’m now realizing its 1 inch smaller on both ends than the mattress I was going to order. I am having a hard time finding a mattress the same size. Will the extra inch on my mattress look and feel right? Not sure why the dimension's are off. I would think a full size boxspring would be the same dimensions as a full size mattress?

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.

Ours did not come with the cover on. It tore as we tried. Both the way in the picture and any possible combination. We have done many other types of furniture assembly; this one had us stumped. Called manufacturer customer service and they were no help. Almost every YouTube video we found showed the cover on it. Will see how this works once in use.

As soon as I opened the box spring mattress I could smell a funky odor. I aired the box spring out in the garage thinking the smell had gone away. Once I brought it upstairs my 3 year old daughter was so excited for her “big bed”. I put the bed in her room and let her sleep on it. By the morning her room had the smell of a musty or moldy smell. She also had developed some type of cough within this time. I called customer service to tell them what was going on with the box spring. They had told me that unfortunately they will just have to investigate the purchase. Investigate. Like I was lying about the smell and the health of my child. I asked them to please come pick up the mattress and box spring. The customer service agent told me someone will just have to get back to me. All I wanted was a new one. Still no phone call, reply or answer. So now I have a twin bed I paid $300 for that I can’t do anything with and I have to buy something new. On top of it go the the dr for this mysterious cough my daughter now has. Overall not happy with the way sams club is going about the whole situation and I have never had a problem beforehand with them. And as a business owner we purchase all of our supplies from there. Not impressed.
