American Airlines partnered with popular bedding brand Casper to create custom-designed bedding for the airline’s long-haul flights. The luxurious bedding set includes a mattress pad, duvet, pillow, day blanket, lumbar pillow, pajamas and slippers for premium cabin members.

The set’s mattress pad is designed to smooth over seat grooves; the two pillows are designed for day and night use respectively and the slippers have a wink design — a nod to the future shut-eye customers will get.

The set is designed from the ground up, specifically for the in-flight sleep ecosystem, based on proven sleep research and award-winning products.

The Casper brand has done well in the younger market and the age of convenience with online shipping services and innovative sleep design. American hopes this partnership will resonate better with younger audiences than Westin or Saks, which brands including Delta and United implement for the same purposes.

The sets will be available on American Airlines’ flights starting in December for customers seated in international and transcontinental first or business class and premium economy. The products available will vary by route and aircraft type.
