This bed fan creates a cool personal microclimate for you by directing air through a flat conduit that tucks into your bed sheets, allowing you to regulate your temperature without disturbing a sleeping partner. The unit takes minutes to install at the foot of your bed. The bottom of the unit houses two whisper-quiet 12-volt fans that produce an airflow of up to 100' cu. when used at maximum power; cool air is re-directed into your sleeping area by an adjustable deflector bar that fits between your fitted sheet and flat sheet, pushing out warm air, keeping you cool. The included remote control allows you to control airflow for one person or two. Plugs into AC. 18 3/4" H x 11" W x 3 1/2" D. (7 lbs.)

If you like to sleep cool at night and are a hot sleeper then get a bedfan. You really will not regret it.
