One of the first things we learned in our research is that sleep positions (and their supposed need for differentiated pillows) are a myth.
Nearly everyone changes positions during the night, which is why we set out to design a single pillow that could accommodate all people and all positions.
Our Journey to the perfect Fill
For initial user testing, we slept on over 60 different kinds of pillows from around the world to find the best fill types out there.
Ultimately, we determined the best solution was to fill our pillow with synthetic fibres, which are specifically engineered to suit a wide range of needs. They have properties that surpass down, they’re hypoallergenic, and they last longer than other fill types.
Two Layers are better than one
After 18 months of testing, we designed a dual-layer pillow. Its outer layer is breathable and soft, while its inner core is supportive and pressure relieving.
All in Good fibres
The Casper pillow’s transformative design is thanks to its cutting-edge fibres. We use extremely short and thin inner core fibres that are 1/20th the width of a human hair. Each fibre is low friction, which creates the pillow’s signature springiness.
The soft outer layer contains longer fibres, which create a luxurious and forgiving layer over the supportive core. Together, each Casper pillow contains nearly a billion fibres.
A new Dimension in Comfort
To get the most out of our innovative double-layer construction, we included a structural element known as a gusset (the 5cm panel that runs along the perimeter of the pillow).
It adds depth for side sleeping support and ensures consistent comfort across the pillow, so sleeping on the edge feels just as great as sleeping smack dab in the middle. Read reviews of the Casper pillow.
