Carry-on mattress for overnight flights

Specially designed mattress pad makes seats more comfortable
Airweave, a “premium mattress company”, has introduced something called the Traveler mattress pad, designed to make airline seats more comfortable and pack easily into a carry-on bag.
Unrolling like a sleeping bag, the Airweave Traveler provides firm support on one side and soft on the other. The cost? $600. But the makers promise it gives a guaranteed upgrade, wherever you’re sitting.
About 3cm thick, the pad meets US Transportation Security Administration standards for carry-on luggage. The core is 90% air, so it weighs just 2.5 kilograms.
Like all Airweave products, it uses a resin fibre that combines “the even support of latex and foam with the fast rebound associated with a coil-based mattress”.
