Sensory play for up to four preschoolers! Our Sensory Table is intelligently designed with four clear, surface mounted removable plastic trays with lids [included, each 10.5"L x 13"W x 5"D] that hold sensory materials for little hands to explore and make clean-up a snap. There's plenty of room for storage underneath, including one open fixed shelf on the cabinet bottom and another just below the table surface that accommodates extra bins [sold separately]. Mounted on four heavy duty, non-marking lockable casters for handy mobility, the 27"W table fits easily through standard doors. Constructed in beautiful, durable birch plywood in safe, non-toxic natural UV finish that won't yellow and withstands rigorous use. Made in the USA. GreenGuard™ Gold certified. Lifetime Warranty.
