My educated guess is that this might also be an aircraft thing. We've heard report just before that BKK had the mattress toppers as well, and our plane was F-HUVC, that just did the BKK rotation the night before.
That, and the printed paper with the mattress topper that reminds the pax that due to customs regulation, the “equipment is part of the aircraft”.
