There are two versions to choose from if you're looking for a Twin XL. Our hybrid collection combines the pressure relief of our original foam with the added lift from resilient springs.
The Wave Hybrid combines the powers of springs, gel and foam for the supreme dream state. The five layers gives you the most support using springs for added lift, and foam and gel for Hyper-Targeted support to provide contouring spine alignment.
Our award winning Casper mattress, upgraded. The Casper Hybrid combines the best of both worlds with resilient springs as the base for added lift and our proprietary foam. The "just right" feel is now even better.
You have three Twin XL foam options to choose from. Want extra cushioning for gentle, weight-cradling support? Or would you rather streamline your mattress and keep costs low? Either way, there’s a Twin XL that’s right for you.
The Wave mattress's added thickness provides targeted ergonomic support, while the breathable, open-cell foam surface provides cooling comfort throughout your sleep.
Our award winning Casper mattress was engineered using feedback and data from customers like you. If sleeping on a cloud sounds good, consider this your sweet spot.
The Essential delivers Casper's signature "just right" feel (not too firm, not too soft) while keeping you cool and comfortable at a lower price.
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 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 foams enable 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!
