How Casper keeps prices low and quality high
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.
Think cool. (No, cooler)
Propriety open-cell foam
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.
Relentless team of engineers
Our team of engineers and designers developed Casper mattresses with body temperature in mind, ensuring you have the most comfortable sleep possible.
Goodbye heat, hello sleep.
The foam is specially designed with up to 5 layers of premium foam (on our Wave) for an outrageously comfortable sleep.
