    Easy to put together, strong, but you can feel the middle support.This product was really easy to put together, and even came with a mini furniture ratchet (thank you for saving my wrist). The drawback to the box-spring is that the middle support seems to be a little higher than the rest of the slats or harder (I can feel it easily – maybe the manufacturer should consider lowering the main support position a bit). I have a thick futon mattress (that’s what I like to sleep on the most), but I think I’m probably going to need an additional bunkie board to smooth out the feeling of the middle support.

    Takes a bit of time and patience to assembleWe bought for our guest room because we did want to move our old box spring downstairs when we moved and risk damaging the walls.My husband and I assembled together in about 30 minutes. Not difficult just a lot of screws.Our only guests so far have been kids (said it was good) but it seems comfortable from short tests.It is a foundation and more solid than a traditional box spring.

    4 years later, only the cover has torn, absolutely worth the priceI purchased 2 of these in February 2018 for my sons who are extremely active (jumping on beds, active sleepers, run and slide into bed kind of kids) and they’ve been amazing. Prior to these I was having to replace their box springs every other year because they’d break them so I got these hoping that I could get 4 or 5 years out of them. So far, I have gotten over 4 years and I honestly do not foresee these needing to be replaced in another 4 years. They’re easy to assemble, easy to move once assembled, and incredibly sturdy. The only small complaint I have is the covers are not as sturdy as the frames. I need to replace one due to my kiddo puncturing it some how and the other cover is showing some threadbare spots and will need to be replaced. After what we’ve been through with standard box springs, only needing to replace covers after 4 years is amazing.

    Love these box springs!I will never buy a wood box spring again! This is my second purchase for this brand of box spring. I have a full size which I bought about 2 years ago and a king size which I bought a week ago. . VERY STURDY! Assembly is about 35 minutes and it comes with a ratchet tool! I love that it comes with a cover, however I was disappointed when it was only a top cover with straps vsa full cover with a zipper. Bring back the full cover and zipper!

    Easiest assembly ever,I’ve assembled many things, and this is the easiest I’ve ever seen. Clear instructions. Labelled parts. Excellent tools. Spare hardware!Also, they provided a clever Allen wrench that ratchets.

    Perfect fitEasy to assemble. Instructions clear and parts well labeled. No issues. Great foundation. Bought two in queen. Not difficult to move into place but simpler with two people.

    Our saving grace !We purchased a home with archway leading up our stairs. But we were unable to maneuver our queen sized box spring up the stairs due to the archway at the bottom of the steps! We went bath and forth between cutting the arch out , cutting the box spring it half. It was a mess! But before making any minor adjustments to our home I searched for a box spring that gets put completely together ! And I found this ! We easily carried the slim box upstairs that it came in and put it together !

  8. JM

    Excellent All-Metal Box Spring!I liked: the price point; the quick delivery; the good packaging; the rapid setup; the low profile, and the strength and durability of the assembled product.

  9. Char K.

    Stop Looking!Seems overwhelming at first because of all the parts, just takes a few minutes to get your grove and then easy peasy! I did it by myself and lifted it onto the frame. It’s sturdy and easy to maneuver!I recommend!
