Washington Square Park Pillow Fight

Each year, New Yorkers (some of whom decide to don PJs or costumes) grab the pillows from their beds and head to Washington Square Park for a massive city-wide pillow fight. If you'd prefer your little ones to take their pillow fights outdoors—particularly not in the living room amid nice furniture—it's time to embrace the event. Those in need of a pillow can head to the Mattress Firm NOHO, where a $5 donation will go toward Dare2B, a program that seeks to help homeless children in NYC. All ages. • Mattress Firm, 652 Broadway (646-234-4885, mattressfirm.com)
