Before mattresses, humans were forced to sleep standing up, which led to sleepwalking, and, eventually, sleep scrapbooking. Go horizontal with today's Groupon: for $50, you get $200 toward a mattress at Sleep Source. This Groupon is not valid toward Temper-Pedic mattresses or accessories.
Sleep Source's fleet of slumbering pads includes more than 40 pillow-top, memory foam, and traditional innerspring mattresses from brands such as Simmons, Serta, and King Koil. The King Koil Highland Firm set provides a solid sleeping surface and box-spring support ($179+), while King Koil's Celeste Eurotop set offers a soft landing for snoozers and their Fabergé eggs ($249+). Sleep Source carries more than 20 adjustable mattresses to mitigate back pain and poor circulation, and equips sleepers with long-lasting nap pads, such as the Simmons queen-size starter Beautyrest set, which comes packed with shape-conforming coils and durable steel ($699).
