Mattress stuffings have evolved by leaps and bounds—from straw and goose feathers to space-age memory foam and digital goose feathers. Enjoy the innovations in sleeping technology with today's Groupon: for $50, you get $200 toward a mattress at America’s Mattress's locations in Montgomeryville, Vineland, King of Prussia, Langhorne, and Prospect Park. This Groupon is valid toward every mattress and mattress set including Tempur-Pedic and Serta iComfort mattresses.

The slumber scientists at America's Mattress provide visitors with the springy equipment necessary for horizontal expeditions into the unconscious. The Newtonia Bay mattress ($599+ on sale, $1,099 regular) is available in firm for proponents of back support and plush for advocates of sleeping in the arms of a massive teddy bear. Pursue recumbence with the Serta Perfect Sleeper Marengo ($799 on sale, $1,199 regular), or transform torpor into restfulness with a Serta Perfect Sleeper Glen Haven mattress with memory foam ($899 on sale, $1,799 regular), which provides balanced support and remembers important dreams so they can be analyzed later for clues to kitchen candy stashes. Customers receive free delivery, setup, and removal for mattress sets priced at $699 or more.
