DESIGNING THE CASPER
Early in our research, we learned there are four key factors that affect sleep quality: comfort, support, temperature, and durability.
Not only did the Casper have to be soft and cushy, it needed to provide excellent support and stay cool through the night. And, of course, it needed to last.
We spent 9 months visiting 15 factories to test and understand the properties of 100+ foam samples.
FACTORS WE CONSIDERED
HUMAN TESTED AND APPROVED
After exploring more than a hundred configurations, we narrowed our selection down to two dozen beta models for qualitative user testing. We invited people from all walks of life to A/B test our most promising prototypes.
To do so, we built mattresses with different constructions on each side so our sleepers could easily compare the differences.
The End Result
Our research led us to the discovery that a well-balanced sleep surface could cater to the vast majority of sleeping positions, body types, and slumber eccentricities.
We developed the award-winning combination of foams of our original design, with each component specifically chosen for its properties and how they work together.
The secret to the Casper mattress is our combination of pressure-relieving memory foam under a springy, breathable comfort layer. The top layer provides just enough sink, and you’ll always feel fully supported by the pressure-relieving memory foam layer beneath.
Because the comfort layer is breathable, the full contouring to your body doesn’t result in the same overheating that an all-memory foam surface creates. Its springiness also removes any sensation of being stuck (and provides a helping hand to indoor sports). See how Casper users review the award-winning mattress.
BETTER FOR YOU, BETTER FOR THE PLANET
Unlike most mattresses, Casper mattresses are free from harmful chemical flame retardants and instead use a purely mechanical fire sock made from silica threads.
We use a Greenguard-certified, water-based adhesive for laminating our foams rather than the solvent-based adhesives found across the industry.
Our foams are certified Certipur, meaning they are all ultra-low VOC and held to the highest environmental production standards. Visit our FAQ for more info.
Because we use high-quality, resilient foams, we’re able to compress our mattresses without undermining their integrity. Our unique compression machine ensures that no undue pressure is put on any part of the sleep surface.
This allows us to conveniently ship our mattresses in manageable boxes. To ship them halfway across the country, it's less than it costs to ship an uncompressed mattress ten New York City blocks.
PARTNERS WITH INTEGRITY
Casper mattresses are designed and assembled in the USA. We ship them directly from our factory, and exclusively work with partners who share a similar obsession for detail and a healthy disrespect for the existing mattress industry.
