Counting sheep is a sure-fire way to invoke sleep, which explains why zero sheep are allowed in air-traffic control towers. Harness the somnolent power of wool with today's Groupon: for $40, you get $80 worth of woolen bedding from Wisdom Of Wool.
Wisdom of Wool purveys comforters, mattress pads, pillows, and wraps made from chemical-free, environmentally conscious wool to promote better sleep. Chemical-free, sustainable wool maintains the body's optimal sleep-temperature zone and won't wake dozers with any nightmarish bleating. Sleepyheads dazedly sink into a regular wool pillow ($54–$72), a 100 percent eco-wool insomnia interloper encased in fully organic cotton sateen, while strained back muscles recharge within the waist wrap ($47¬–$54.50). Specifically engineered for summertime, Wisdom of Wool's light comforter ($135–$329) swaddles sleepers in a breathable covering that resists mites, mold, mildew, and dust from the sandman.
