I purchased this in the past and loved it. This was easy to put together, a hammer is all you need really. I was able to put it together by myself. It looks good and is very sturdy. Will be easy to take apart and move as well. Would definitely recommend. However, this time there was hardware missing off of the middle support bean that allows it to slide into the frame. I would like a replacement piece.

This is a solid box spring foundation and has a classy look almost a gray tweed type material, ive matched mine with quiet balance frame and a dream cloud 14in mattress all compliment each other perfectly i also added a headboard and it's all perfection but back to the box spring very sturdy and the assembly was so easy it shipped quickly and the sale price was an instant draw . It's quality , it's a good use of your money you won't feel taken. I'd highly recommend this one.

A couple of years back, I purchased a twin Zinus "Smart Box Spring" which was basically a grown up lego set and took me at least 1 hour to assemble and then get into the cover. So when I purchased this set, I had prepared myself for the same ordeal. This couldn't have been easier to assemble. There were 2 short pieces that were held together by 2 "pegs" and 2 long pieces held together in the same way. All pieces were clearly marked "Up!" so you could easily figure out how to get the pieces to line up and insert said pegs. It was together in less than 10 minutes! The slats sit on top and hopefully will hold -- I haven't had a chance to try them out yet. W My only "ding" was when we were unboxing the Casper Mattress, we had to be careful to keep the slats from "bunching up" underneath... but that wasn't a huge issue. While Zinus was much cheaper, I was extremely relieved to have this be such an easy assembly and wanted a foundation that I figured was engineered specifically for my mattress. [LCVR]

I thought I was going to need a mattress. But this foundation has added the needed support and firmness to my existing mattress. I won’t need a new mattress and have saved hundreds of dollars. It is a very solid foundation with wooden slats. High quality for a reasonable price. I paid extra to have it installed and the old foundation taken away. Excellent choice -they were in and out in 15 minutes. (Although the installation is not difficult)

I took a gamble buying this since the Amazon site has the wrong size shown. It lists the size of the Casper Twin foundation as 79" in length. That's the right size for a Twin XL (where it shows the same dimension), but would be too long for a twin bed frame and a twin mattress. Fortunately, the twin XL foundation was out of stock, so I reasoned that it couldn't be the same as a twin (which was in stock). I assembled it in about 10 minutes. Good instructions and very easy to do. And measured it. It's the proper length, which is 74". Makes sense, but worth noting so other folks can order with a bit more certainty. Haven't gotten the bed not the mattress yet, but I'm happy with the purchase. Especially so, since the mattress and the foundation together were about $150 less than the exact same mattress by itself!
