There are three versions to choose from if you're looking for a King. Our hybrid collection combines the pressure relief of our original foam with the added lift from resilient springs.
Our most advanced mattress. The Wave Hybrid has hyper-targeted support combined with active springs, allow for better airflow.
The Wave Hybrid combines the powers of springs, gel and memory foam for the supreme dream state. The five layers give you the most support using innersprings for added lift, and foam and gel for Hyper-Targeted support to provide contouring spine alignment.
Our Nova Hybrid features a luxuriously soft top layer making it our most plush mattress. It features hundreds of resilient springs, added lift, airflow, and a bit of bounce to have you sleeping in the clouds.
Our award winning Original mattress, upgraded. The Original Hybrid combines the best of both worlds with resilient springs as the base for added lift and our proprietary foam for pressure relief. The "just right" feel is now even better.
Want an extra layer of supportive memory foam for your Casper King Size bed? Or perhaps you’d prefer a more streamlined model? Don’t worry - we’ve got you covered. Take a peek at these Casper King options:
Our award winning Original king bed was engineered using feedback and data from customers like you. If sleeping on a cloud sounds good, consider this your sweet spot.
The Element pro delivers Casper's signature "just right" feel (not too firm, not too soft) while keeping you cool and comfortable at a lower price.
The main difference between a king and a California king is the mattress size. A standard king mattress is 76" x 80", while a california king mattress is 72" x 84". If you’re deciding between the two, we recommend taking measurements to ensure the Cal king will fit, allowing enough space for the bed frame which can add inches to the perimeter of the mattress depending on the design.
A split king mattress has the same dimensions as a standard king, but can be beneficial for couples who have different preferences or opt for an adjustable base. The combination of the split king mattress with the adjustable base enables both partners full control of their side of the bed while providing increased motion isolation.
Would it surprise you to learn that an eastern king shares the same standard mattress sizes as the standard king? Well, it’s true - there really is no difference! According to mattress lore, the Eastern king was nothing more than a counter to the California king, created by a Los Angeles merchant shortly after the Second World War. Since we’ve come to think of this size as a standard king, the “Eastern” has largely dropped off.
If you’re upgrading from a full or queen mattress to a king, you may want to consider upgrading your pillows as well. Two standard pillows will leave about 12 inches of empty mattress on either side of them, while two king size pillows fit across a king size mattress with about 4 inches on each side.

For sleepers looking for maximum support and pressure relief, our hybrid king mattress options offer the plush feel of a memory foam mattress with the support of a sturdy box spring mattress. For couples who want to be together while maintaining their own sacred sleeping space, a split king might be the best fit.
When Casper was founded in 2014, many people were skeptical. Would consumers really buy a mattress without testing it first? Several years and numerous awards later, we have an answer: It turns out no one likes visiting stuffy mattress showrooms to make high-stakes purchases under the scrutiny of needy salespeople. (Who knew??)
Everyone loves the ease and convenience of buying online from a trusted source, and having a high-quality mattress shipped in a box to their doorstep for free. And people keep spreading the word that our mattresses deliver unparalleled comfort and support, top-notch construction quality, and high-tech, innovative design.
But the Casper experience isn’t just about quality, trust, and transparency. Our mattresses are a mere fraction of other brands’ prices. That’s because we’ve flipped the mattress industry on its head. By eliminating showrooms and middlemen, we keep our costs low - and pass those savings on directly to you.
Nothing will ruin a good night's sleep like waking up hot and sweaty. Our foam mattress enables airflow, so you stay comfortable and breezy through the night.
Our team of engineers and designers developed Casper mattresses with body temperature in mind, ensuring you have the most comfortable sleep possible.
The foam is specially designed with up to 5 layers of premium foam (on our Wave) for an outrageously comfortable sleep.

I was skeptical at first about a bed that can be put in a box, but I decided to give it a try anyway and so glad I did!! My wife and I have been having back pains probably due to our old mattress and I noticed the difference the first night of use.

We absolutely love our Casper king! It is incredibly supportive and soft at the same time! It's big enough that we feel like we are sleeping in separate beds. Delivery and setup were a breeze! Highly recommend to everyone to try a casper!
