Comments

Silver Fox: This was super easy to put together, the cover was a bit tricky alone, but I managed. I also bought a memory foam top, which works great but the sizes are slightly different, very minor problem..

Amanda Roberts: After having to return another item from another company I was a little skeptical that this one would actually work. Like the other I looked at reviews. I watched a video and bought it. This was truly easy to put together. As a single person I didn’t want to call anyone for help. And I didn’t have too! I was able to put this together within 75min. It was super easy and instructions were not had to follow, just put the numbers together that are labeled on the parts. Super happy with this purchase.

Arturo Velasquez: Bought this during the pandemic and thought moving, weight gain from me partner and myself product still works great. There are no dents in the metal, zipper works on cover and cover still stitched and hasn’t come apart. Lightweight framing has made it easy to fix and move around. Giving it to someone else only since we’ve upgraded our bed size but if not I’d be using this product still.

April Shells: Great choice if you don't want to buy separate bed frame and box spring! The instructions aren't the clearest for someone who isn't experienced at building furniture but scrolling through the reviews helped me figure some things out. It took me roughly 2 hours to get it all together and set up (I'm pretty slow going-afraid I'll mess something up). The top slates were difficult to push into place, you just need sheer force to push them in, and some of the side pieces didn't fit together without also forcing metal to move. Otherwise, seems like a great frame so far, will update if anything detrimental happens

SP-Fisher: Sturdy and comfortable for our mattress. We added a platform on top to keep the mattress firm and in place.

Patrice Arsenault: Lit simple de bonne qualité.

Brian Ross: This was an easy to assemble product not least because the ends of each part are labelled, so you know what way round it goes and what to bolt it to.

Because it comes in a thin box it was easy to get up the stairs - my attic is inaccessible to a pre-built queen box spring.

It’s sturdy and does not squeak - I was worried about that being that it is metal. But not a sound.

Very happy with this. I’ll buy again and probably will never go back to the wooden ones.

Yours Truly: It's tax refund season, and it's been about ten years since I bought my mattress and box spring. Having moved into a new house with a currently empty guest bedroom, I figured the time was right to replace my old bed; it can go into the guest room and I'll get a new one.

After some shopping, I ended up on a Zinus foam mattress and this box spring. The box spring arrived in a large box--the box itself was about 6 feet tall and square, maybe 9-10 inches on each side. I was able to move it on my own, but I'm also a big strong guy; if you're by yourself and not a big strong guy, you might need some help moving it.

I pulled the old mattress, box spring and frame out of the bedroom so I'd have plenty of room to work. I opened the box, reached in and pulled out the first part. And this, my friends, was the moment that immediately sealed my five star review.

If you're looking at this, you're like me: you've assembled more than your share of "RTA" (ready to assemble) furniture in your time. Your knuckles start to hurt if you even *look* at an Allen wrench. You've lost count of the number of times you've been trying to tighten a bolt with that cursed hunk of hexagonal...

jgjg: A review for Casper mattress owners

I bought this frame to serve as the base for my brand new king size Casper mattress. The box spring kit arrived a few days before my mattress, allowing me a little time to do some research on the best foundation to use for a Casper mattress. According to Casper's official documentation:

"The best option is a slatted base frame (with slats no more than three inches apart) or a firm platform. With metal frames, you want to make sure that the base has unyielding wooden slats that are thick enough to support the bed."

Based on this information I started to panic a little bit. When assembled, this frame has SIGNIFICANT gaps between the metal support rods, and definitely would not meet the 3 inch gaps recommended by Casper (in some spots there are big squares of space). I decided to go to a few mattress stores in town to look into a more traditional wood box spring, and found that every box spring in stock seemed to all have slats that had much more than 3 inches between them. After some consideration, I decided I would assemble the frame and if it felt sturdy enough I would go buy some lumber from the local hardware store and...
