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!

Totally impressed with the design of this box springs. It is well made and an ingenious idea for the folding mechanism. The covering for the frame is soft and well made. The overall structure is strong and gives the mattress excellent support. I ordered this for a guest bedroom but will consider ordering one for my bedroom. Highly recommend. Shipping box was easy to handle.

The box springs were easy to get in the house, up the stairs, unpacked, and folded open. Work very well, stable, rigid, and the fabric cover makes them look like real box springs from the outside even though it’s steel tubing on the inside. Very satisfied.

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!

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..

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.

The craziest thing of this BiFold Box Sping is the Assembly process. It took me less than 5 minutes to break the box seal, unpack each of the Boxes, Lay them on the wooden slats of my Bed and unfold them to zip the clothing cover. And I'm pretty sure, It will take the same amount of time to pack them when moving as well. Don't hesitate. Just get this Box Spring and leave everything else to Zinus.

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.

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.

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.
