Sealy, the company known for providing innovative sleep technology with its Posturepedic, TrueForm, and SpringFree mattresses, on Monday unveiled the Destination, a mattress designed to simulate the sensation of drifting off to sleep on a moving bus. 'Whether you choose the window or the aisle model, you'll feel the difference after just one night, especially in your back,' said Sealy spokeswoman Georgia Mitchell, who added that users' muscles are repeatedly stimulated throughout the night by the bed's patented 'bounce and rattle' mechanism. 'Most importantly, the hyper-constricted sleep space, coupled with the ergonomic, semi-upright design, cuts in half the tossing and turning one experiences on a regular mattress.' For an extra $150, consumers can purchase a specially designed crumpled-jacket pillow as an alternative to using their fists.
