Ordered the spilt king box spring as we just needed to replace that part of our bed. Arrived promptly and oh so easy to put together, NO tools required! Highly recommend.

It's very nice it was ordered for our spare room so we really didn't sleep on it. We will soon as we are doing our master. If you can send us a discount i may be able to talk the wife into a king for us.

Rather than try an new mattress decided to try a new base. Could not be happier with that decision. Traditional box springs just didn't cut it for me. If you have a mattress that you like, but is not as comfortable as before...give this a shot!

I was looking for king size box spring for my second floor bedroom. The stairs going up are narrow and the convenience of the folded box spring doubled! I was skeptical at first, but they're perfect! Easy to move and easy to open up!

Great. I put it on the floor and put a very good 13" high air mattress on top. Creates the perfect height bed for guests. And the 2 (2 separate visitors) love it.

Inherited awesome king mattress. Tried frame with support. Needed box spring. Bought these foldable duo box springs. Could not be happier. Easy to open and unfold. Unbelievable nights sleep. Yea! Reasonable functional and easy to move

I purchased a low profile 4" steel box spring. It was a lot lighter than I thought it would be. It was assembled and you just unfold it. It's awesome.

It"s been a hard year for everyone, & the economic instability makes it important to spend carefully, which is why I bought this set of King mattress w/the box springs. Matress is OK (will review it seperately), but the box "springs" (it really is a metal ladder w/o any give). I got the items on different days, so be aware that can happen (& boxes torn to shreds, but comtents OK). Followed all online instructions, brought down all lamps, removed the finials on the bed, & got box open very carefully (afraid the whole time these would explode in my face like a can of biscuits). Got out the 2 frames & searched for instructions in vain; there was a picture showing how to unfold the pieces, but nothing further. I went online, looked for instructions, pictures, nothing told me which way to orientate the positioning. There was a yellow sticker marked "TOP", but I didn't know if that meant that that side up, or that it meant put thar portion at the headboard, or manuveur the matress so that when open that "TOP" unfolds in that direction. I thought once unfolded, it would be obvious, but when I unfolded the first one, the cover did not move with the springs. I then spent several hours trying my best to stretch the cover (even unzipped) to fit the frame. I kept going back to the online reviews & descriptions to see what others did, the only video showed how to unpack the mattress only, NOT the springs. It was 58 degrees outside, but I was sweating & short of breath, & hadn't even unpacked the mattress or the second box spring. Cried a little, almost smothered my cats, my hands and wrists are covered in bruises, I bled from somewhere b/c I managed to mark the white part of the cover with small drops of blood. I am an average sized woman, & thought since I was able to cartwheel the extremely heavy boxes into my home, that I wouldn't have issues with the weights of the items inside, but was clearly wrong. My husband got home from work (I thought I'd have it all done hours before he got home-WRONG). We had to end up just ditching the box springs, put back the previous ones, & put the new mattress on them. Today, I feel like I participated in the "Hunger Games" (and LOST), or that I would have been better facing a dragon, albeit w/o a wand. All that said, I whole purpose of getting a new matress was b/c my back has been hurting, and it hurts even more this morning, probably slipped a disc or aquired a hernia wrestling with these ridiculous, unweildy & difficult items. Now I know why stores sell mattresses for thousands of dollars--they have to pay some masocist (sp?) to set them up. I think my long term doctor's bills I will be expecting in the near future & also a new potential career as a drinker will cost more than the money I thought I was saving by purchasing these inexpensive mattresses. In child birth you have an option of an epidural, but this experience was so frustrating and hurtful on so many levels, I think an animal tranquilizer should also be included in the box with a fifth of Pappy VanWinkle (I got a dementor in mine, apparently). God bless us, every one (I cursed so much yesterday I need to get some communion and light a candle in a church, I think).

I was skeptical when I saw the box but what a great product.

Wonderful and Supportive. Like sleeping on a Cloud. Amazing how it fits in a Box & is so Easy to open up and put cover on.
