Initially I was a little cautious about the claims being made but upon receiving and setting up, it is just as advertised and more. Setup was beyond simple and because the foundation is now so sturdy, the feel of our bed has improved. Needless to say I will recommend and will purchase should the need arise again.

Arrived quickly and was easy to fold out. Also, this product is cheaper (and obviously, much more convenient and sturdy) than the junk others sell at the big box mattress stores. We recently bought an Avocado King mattress and that company does not sell box springs so they recommended Zinus. Glad they did! The new mattress sat too low on our new bed but now with the steel box springs, it is perfect. Note that we originally had the box springs up-side down which is not comfortable. After a night's sleep, we woke up smarter, did the flip and now the new bed, new mattress and new box springs work in harmony.

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.

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 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.

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.

This box spring frame is a miracle! I have a miniature (short) stairway. A regular queen box spring would not fit down it. Zinus, Jayanna was the answer! It arrived in a timely manner, great condition and was awesome to set up. Really sturdy, 15 minute set up from box opening to on the frame. Highly recommend! Make your life easy! As a single woman don’t rangle a queen box spring, order 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!

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..

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!
