These 12 airplane beds let you really sleep on a flight

Cathay Pacific's First Class isn't one of the newest products on the market, but it's still a leader in the field.

Seats are arranged three-across rather than the standard four-across, offering plenty of room to relax.

There are complimentary sleep suits, designed by Hong Kong tailor PYE, and luxury bedding with 500-thread-count cotton duvets, pillows and cushions (as well as praline treats). Underneath the sheets, the seat is equipped with massage functions to aid in stress relief and relaxation.
