This 6-piece foam block set is made from high-density EPE foam and skin-friendly PU leather, offering a soft yet supportive surface for toddlers. Each piece is equipped with hook-and-loop fasteners for secure connections and reinforced stitching to withstand active play. The set includes an arch, a large rectangle, a small rectangle, a triangle, and two fan-shaped blocks, allowing endless configurations to keep playtime engaging. The convertible triangular block adds versatility, giving children the option to slide, sit, or stand on it. Designed with bright, eye-catching colors, the set enhances any playroom, daycare, or preschool environment while helping toddlers develop color recognition. Suitable for children aged 12 months and older, the climbing blocks encourage motor skills, hand-eye coordination, creativity, imagination, and cognitive development through climbing, crawling, and sliding activities. The waterproof and stain-resistant PU leather cover makes maintenance simple-just wipe with a damp cloth to keep it clean. The smooth zipper design also allows easy cover removal. In beige color and made of PU and EPE materials, the set includes a large rectangle (16" x 12" x 10"), a small rectangle (16" x 12" x 5"), an arch (23.5" x 16" x 18"), a triangle (23.5" x 16" x 15.5"), and two fan-shaped blocks (17.5" x 16" x 2").
