A child’s imagination, like the universe or a confused soccer player, knows no bounds. Nurture blossoming creativity with today’s Groupon: for $16, you get a five-admission punch card to the Chelsea TreeHouse indoor playground at its new location (a $32.50 value). Babies from 0 to 12 months old and any person aged 16 or older accompanying a child are admitted free.

Voted Best Indoor Playspace by Nickelodeon's Parents Connect, Chelsea TreeHouse has since flowered into a 2,000-square-foot, three-level play palace where children frolic and tumble on a host of pintsize attractions. At the new location, kids can learn about gravity on five exciting slides and on swinging bridges, or gather to construct a miniature particle accelerator in a separate toddler area. Parents can view their tots from afar while perched on leather couches and comfy chairs. The fresh-faced facility also boasts its own basketball court where kids showcase sweet, tube-socked moves. Though not included in today's Groupon, the TreeHouse crafts a wide assortment of healthy snacks, ranging from guilt-free fruit and homemade baked goods to hearty soups and stacked sandwiches alongside a gourmet coffee bar. A generous admission policy grants children all-day access to the play land, foregoing the need to switch disguises after every restroom break.
