Fly from Sydney to Hong Kong on a Qantas Airbus A380 and you'll find the 180-degree fully flat beds, but a Qantas Boeing 747 on the same route has angled lie-flat beds.

Seat configurations of Airbus A380. The Airbus A380 has two full-length decks of 49.90 m (163 ft 8 in), though the upper deck has a slightly reduced usable length due to the curvature of the front fuselage and the front staircase. The main deck measures 6.58 m (21 ft 7 in) in width and the upper deck 5.92 m (19 ft 5 in).
