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.

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!

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.

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 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 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.

It's only been a few weeks but so far it's pretty good. I'm not waking up in pain. Aside from my 3 year old waking me up and wanting to come lay in our bed..I have not woken up on my own in the middle of the night. If that makes sense. We also bought one for our 5 year old and he seems to be sleeping peacefully as well. I'll let you know in a few more weeks how I feel..

It goes together easy but The stringers go only across and a true box spring has 4 inch squares across the whole top that the mattress sits on. With this you have to put 1/2 plywood on top of it to hold the mattress correctly. This is only good to put a conventional box spring on 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.

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?
