From the manufacturer

The Casper Foundation

We know older box springs’ slats tend to be too far apart, leaving room for a mattress to sag. Our foundation’s slats are positioned a perfect four inches apart for optimal support. Say hello, to your new box spring.

A Seamless Pair

Casper foundations and mattresses are the perfect pair. We spent over a year developing the Casper foundation, so its design has the same considerations as our mattresses. It comes in the classic Casper chambray, so it goes perfectly with the rest of the Casper products.

Experience Our Comfort

We recommend you use our Foundation with a Casper mattress to get the full experience. A strong and level foundation helps our mattresses to perform at their peak for a decade or more. The Casper Foundation is here to support you.

Built to Last

The Casper foundation is an especially durable base that was extensively tested against weight distribution and impact. Engineered with solid wood, The Foundation has been rigorously tested for durability and proven to stand up to years of sleep.

Reviewed in the United States on December 29, 2022

Size: California KingStyle: FoundationPattern Name: Box SpringVerified Purchase

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 got a new bed frame that needed a box spring. After evaluating a number of options I gave this a shot. It's pretty easy to assemble and it provides great support for my Costco Casper mattress. The nice thing is that when I eventually move this will be much easier to deal with than a box spring.

Bought Casper system in Queen for my 270 pound football player son. Easy assembly and sturdy. Second Casper Foundation we've bought. This time we're using a Casper mattress. (Master bedroom has a king with conventional matress on Casper foundation.) Bought the Casper bed frame as well. While the frame was more expensive than generics, it was worth it get something STURDY. Center supports add strength. Bed frame a perfect fit with the foundation. Casper mattress purchased separately at COSTCO at better price than Amazon. Delivery was smooth. I was able to assemble by myself. Recommend opening box and bringing parts upstairs one at a time to assemble in the bedroom.

Great purchase

Reviewed in the United States on June 9, 2021

Size: QueenStyle: FoundationPattern Name: Box SpringVerified Purchase

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 problem
All 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!

Twin Sized

Reviewed in the United States on January 9, 2022

Size: TwinStyle: FoundationPattern Name: Box SpringVerified Purchase

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!

A very strong and heavy platform that gives confidence when laying in bed

Reviewed in the United States on September 24, 2022

Size: KingStyle: FoundationPattern Name: Box SpringVerified Purchase

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.
