Industry woos seekers of sweet dreams

At Four Seasons Hotels and Resorts, new beds allow guests to play Goldilocks and choose one of three mattress toppers, from soft to firm, for their perfect night's sleep.

In the air, Etihad Airways - after almost two years of research with the American Center for Psychiatry and Neurology in Abu Dhabi - just introduced a sleep program that includes all-natural mattresses, mood lighting, noise-canceling headphones, pillow mist and calming pulse-point oil.

And at sea, Celebrity Cruises has outfitted some suites with mattresses that can be adjusted to suit the whim of the passenger.
