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.

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.

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.

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!

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.

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.

Husband falls asleep in 2 seconds. I'm still a little restless, just because I tend to think about why we waited so long. All I want to do is be in my bed and on the weekends i make time to get a nap in. Earlier I told my coworkers, "I think my mattress is making me lazy because I just want to be wrapped up in the comfort." My lower back pain is gone! Yay! We will definitely be purchasing this brand for our kiddos soon. Thanks Zinus for an Amazing quality product at an outstanding affordable price. P.s the kids loved the bubble wrap and the coloring pages.

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!

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.

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.
