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 at Bedzzz Express. This Groupon is valid at locations in Huntsville on Whitesburg Drive and University Drive and in Madison on Madison Boulevard and Highway 72.

Bedzzz Express's trained staff pairs patrons with mattresses suited to their slumber preferences, stocking a bevy of models from makers Simmons, Serta, and Southerland. Sagging bedsprings can cause poor sleep and back pain, whereas a new Southerland Bristol firm ($199.99) cradles bodies like a giant wearing mittens. Alight upon the Southerland Sheffield ($399.99), which embraces discerning spines with a firm or pillow-top choice, or rise rejuvenated morning after morning from the Simmons Far Hills super pillow top ($999.99). Bedzzz also carries adjustable beds by Leggett & Platt, which rise and lower on command to allow people to assume comfortable positions before sleeping, watching TV, or holding their feet in the air until their toes get tingly. Though delivery is not included with the price of this Groupon, same-day delivery within a three-hour window includes removal of current mattresses on request.
