This 3-in-1 kids triangle set offers three creative ways to play, consisting of a triangular ladder and a removable double-sided ramp that can serve as both a slide and a climbing ramp. The ramp can be attached to the Pikler triangle, which can also function as a crawling tunnel, creating a multi-functional activity center. The triangle ladder features multi-level adjustable heights, and the double-sided ramp can be fixed at 5 different tilting angles, suitable for children over 3 years, providing varying levels of challenge and adventure. Safety is a priority, with a stable triangular structure, anti-tipping safety straps, and sturdy connections ensuring secure support. Made from plywood and pine wood, the set features rounded edges to prevent injuries and provide a safe play environment. The collapsible design allows the ladder to be easily folded and stored, making it convenient for families with limited space, and the top hole on the height-adjustable device facilitates easy folding for placement under beds, in corners, or even in a car trunk.
