Fantastic!! Bought the King Size. So incredibly easy to open, unhold and zip up!! Sturdy!! Better than a wood frame box spring. Height is 9". Was delivered right into my living room. Great product from a great company! Very glad I bought it. Thank you!!

Zinus King Size Foldable Box Sring Mattress 2 pcs

Easy to assemble but not needed for the mattress purchased although Sam's suggested it. It makes my bed sit super high; so much so that I need a step stool to get on the bed.

You May Not Need It

I purchased the queen  size.  I was able to carry half 2 sets of long  narrow stairs. Easily undold them . Impossible to do it if  the box spring was not divided and folded.

Excellent  to carry and set up  for a petite woman

We couldn't get a traditional box springs up the stairs, it got stuck.  This box springs is not only a split queen, but each piece also folds in half!  How do they do it?  I have no idea!  Genius!  It came in a small-ish box, so I was worried that they had only sent one box springs....I was wrong!  They were both folded up nice and neat inside the box!  My husband and I had to drag them upstairs together, because they were kind of heavy and it took both of us to get them out of the box, but then we very easily assembled them.  You just open them up, and pull on the frame and Voila!  The box springs spring into life!  All we had to do then was run the zipper around the fabric and they were finished.  Probably only took 15 minutes to set up.  And now we have a proper support for our mattress--sleeping on two mattresses was like sleeping on quicksand, everything sank towards the middle!  Would definitely recommend this!

Folding Split Queen Box Springs

5 stars! Love the Zinus Night Therapy BiFold Box Spring! I previously purchased a King size for myself, and liked it so much that I bought another, a Queen size for my daughter's bed....she loved it as well. This box spring is so convenient! All you have to do is just unfold it, and it's good to go. The only minor thing I wish was different, is that it would come in one solid piece instead of two separate pieces. It's kind of like having two twin box springs instead of one box spring. Other than that....great!

Buy the Zinus Box Spring!

Purchase for college student apartment. Very sturdy, but one complaint. The box spring arrives folded with the cover partially on. The cover is very thin, so it must be handled with extreme caution  to not rip it. I found it best to remove the cover from the folded box spring, unfold the box spring and then put the cover on the unfolded box spring.

Sturdy Box Spring, Fragile Cover

Great bed frame

Good quality steel frame with heavy cloth encasement, easy set up, not too heavy to manage with one person.

Good quality steel frame.

They are a lot higher/taller than they need to be. I need a step stool to climb up on my bed.

Really tall, height wise.

I bought two queen folding box springs twice before and I liked him very much. This time I received two smaller box springs that equal the size of a queen and I do  not like them. It was not mentioned that they were going to be two separate box springs that you put together underneath a queen mattress. It causes things to shift around and I don't like this at all!

Not the same as before.
