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.

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.

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!

I have been using the king-sized version of this mattress and bi-fold box-spring in my guest room for the last 2 years and all of my family and friends love it. Every single one of them tells me how comfortable this mattress is when they stay. It is a very firm, supportive mattress, even after 2 years or regular use. I plan to buy a the queen set for my own bedroom very soon and my mother plans to buy one soon as well. If you want a softer bed, put a 4-inch memory foam topper on it. The combination of firm support of the mattress and softness of the memory foam will make it feel like you are sleeping in a cloud.

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..

Never could have imagined how wonderful my new Zenus bed box spring and bed frame are but the main thing is I sleep pardon the expression like a baby and that doesn't mean I wake up and cry a lot! Fabulous support and yet feels so soft so comfortable I can't believe I didn't know about this until a few months ago. I am so glad that I got the bed that I got my back feels great my hips my neck everything thank you so much Zinus I couldn't sleep without you. Fabulous support and yet feels so soft so comfortable.

I had already purchased the 13" Night Therapy Deluxe Euro Box Top Spring Mattress and needed a new Foundation. The video that showed the Night Therapy Bi-Fold Box Spring Folding Foundation-Full showed it being placed on the existing full size bed frame. When I received this bi-fold foundation, it did not fit my existing frame. I checked and found the Night Therapy Smart Base Steel Bed Framed Foundation-full, for $100 less. I now have my new bed setting on the floor because I ordered the wrong foundation. In that respect, I am not satisfied fully with this purchase. Maybe this will help someone else purchase the correct items.

So far, we are very pleased with our mattress. The box springs were genius- theycame right out of the box and assembled immediately. This was only our 2nd night of sleeping on our mattress, but they’ve been wonderful so far. The chemical smell is a bit offputting in the beginning, but it’s alrwdy starting to fade. I’ve been telling everyone about our mattress! Can’t wait to keep sleeping comfortably. and at 35 weeks pregnant, that can be difficult!

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.
