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 $49, you get $200 towards mattresses and mattress sets at Dynasty Furniture in Winston-Salem. Each purchase includes a complimentary set of ultra-plush pillowcases.

Sharing an expansive facility with the NC Art & Antiques Mall, Dynasty Furniture provides homes for dozens of foam mattresses and box springs in four different sizes. Shoppers can browse through a variety of snooze pads, including twin Sleep EZ II sets ($329) and full Energie Series sets ($488), to find the ideal mattress for deep slumbers and bounce parties for off-the-clock sheep. Designed for household nobility, the Balance extrafirm queen ($799) or king set ($999) facilitate royal rests with spacious mattresses that boast 2 inches of extra firm foam. Dynasty Furniture's staff invites customers to stroll around the facility and "test rest" any product by lying down atop the mattress for 10 minutes and have one-sided conversations with a bedside teddy bear.
