Easily adapt to your child's natural progress through each developmental stage! Designed to fit any of our existing Pikler Workshop climbing triangle frame sizes, the Extension Boot adds an extra climbing rung and eight inches of height to supplement your child's growing activities and keep them challenged.
 
For families with children at different phases of development, the Extension Boot can be inserted and removed by a supervising adult to raise and lower the triangle, making it easy to accommate the skills of each little adventurer.
