Your cart is empty.Our foundation provides excellent support under any Casper mattress and can be assembled in minutes -- no tools required. It can also be quickly disassembled if you are moving or need to maneuver around tight corners. Older box Springs’ slats tend to be too far apart, leaving room for a mattresses. Our foundation’s slats are positioned a perfect four inches apart for optimal support. Engineered with solid wood, it has been rigorously tested for durability and proven to stand up to years of sleep.

I've ordered 3 of these for different locations over the past 3 years. They are very study and easy to put together. Very clever design. Attractive fabric wrap.

We like this platform which we have resting on a metal bed frame and it feels solid enough to support our winkbed. I spent a lot of time being sure everything could handle the weight of what it would carry, meaning the bedframe had to be able to support the weight of the platform plus the mattress, and the platform had to be strong enough to carry the weight of the mattress. All those weight limits are in the various item specifications. I hope that helps.P. S. I attached two photos (left and right) not often seen showing how the platform rests on the metal bed frame. You can see the width of the wood and how most of the width is supported by the lip of the frame.

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.

If you are looking for a box foundation, this is the one to get! We searched and searched and read tons of reviews on all different types of box springs. After reading so many, we landed on this from Casper. We had purchased a memory foam mattress, and realized it needed just a bit more support than the mattress alone. The biggest difference between this box spring and the others is the material. We had read some reviews about metal box springs, and heard that they eventually would squeak. That is a dealbreaker for us. Casper foundation is made of a sturdy material and comes with the Casper reputation. It was incredibly simple to put together. Just like any square item, you will want to ensure that they are lined up well prior to inserting the pegs. No tools were required. However, we did use a hammer for ease of positioning. It wasn’t necessary though. The difference with this boxspring underneath the mattress is night and day. It was well worth the additional price, and just like purchasing my mattress, the money was well spent.

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!

I don't often write reviews but this product is worth it! It is perfect. I purchased a headboard/footboard with side rails from an up scale consignment store. Then purchased a memory foam mattress (Amerisleep, made in USA, excellent!). But the bed was not designed for the weight of a memory foam mattress. I added slats with legs but it didn't raise the mattress up enough. Did my research and found standard box springs can't be used with memory foam. And then I found the Casper box spring specifically designed to solve my problemAll the reviews were positive, so I ordered it. It was the easiest thing ever to put together (I'm 68 and didn't need any help!) and it fits perfectly. My new mattress feels even better too! This is very good quality and I highly recommend it if you have an older model bed and want to buy a memory foam mattress!

So easy to transport up the stairs and to assemble. We are also impressed with the mattress foundation support and quality. Much better than the traditional bulky box spring design.

Dude, what a total nightmare it was putting this together. There are four big pegs. It says so in the " simple" directions. The trend of providing 4 step directions with minimal explanation needs to end! It works in favor of the company by implying that it's so easy to put it together and if you have any questions and/;or it's not working, then just read the minimal steps again. The pegs don't line up, but when you first fit them in, it seems as if all four will line up, then, when they don't, you think, ok, I just have to pull this one peg out again and all four corners will line up . Right!!! The pegs come out " sometimes " but not " every time" you need to readjust the sides of the frame. The good news here is, that I never finished putting this together perfectly...one of the pegs is inserted only half way, and one of the sides is not aligned and I gave up, thinking the whole thing may have in on me in the middle of the night. That never happened and have been sleeping on it fine for over two months now. It is sturdy as you need it to be. I advise two people get mad at eachother and put this thing together as a team, or spend the extra money to save the hassle and risk of putting it together in a haphazardly fashion.
