Encourages early mobility and exploration! Babies and young toddlers will enjoy crawling through the two large openings [each is 14.75"D x 17"W x 17"H] to explore the images provided by the safe, shatterproof acrylic mirrors mounted on each interior side wall [four total]. The middle compartment features two open fixed shelves [each is 14.75"D x 9.12"W x 8.25"H] and two clear plastic trays [included] that put toys, manipulatives or other items within easy sight and reach by early movers. The cabinet surface is just the right height to foster a young child's confidence to go from crawling to standing, then take their first steps. All corners and edges are rounded over and finished smooth for safety. Sturdy construction with no visible screws or joinery for a nice finished furniture look.
