Although the best mattresses feel as soft as clouds, the worst mattresses are clouds that send sleepers plummeting back to earth. Rest on firmer billows with today's Groupon: for $50, you get $200 toward a mattress from Beds and Bedding on Mercer University Drive. Groupon values can also be applied toward the cost of shipping.

Beds and Bedding's mattress mavens stock a slumber-surface storehouse with sleeping accessories from name-brand designers including Simmons, Englander, and Jamison. Pick up an Englander pillow-top queen mattress ($299+) or a queen-sized Sealy Posturepedic ($499+) to complement dreams with sensations of angora-like softness. Cushy Englander twin sets ($149+) support sleepers during eight-hour naps, and a Jamison Resort all-foam queen set ($599+) renders sleeping a more queenly endeavor than polishing a diamond-encrusted flyswatter. To keep shoppers slumber-smart, friendly staffers wait nearby to chat and answer questions about durability, foam encasements, and techniques for gently informing old mattresses they are being replaced.
