Crafted using responsibly-sourced birch plywood and beech wood, it's a wonderful sustainable option for mobile little ones exploring their adventurous side. Through physical developmental play with the Picler system, children gain muscular and cardiovascular strength, build self-esteem, improve gross motor skills and explore their imagination simultaneously. Each of our Picler accessories is compatible with the others, and secure locks connect the system's pieces safely and effectively while holding them in place. By connecting them together, your toddler has an entire playground to explore! They are also finished with a water-based varnish for smooth, comfortable play and easy cleaning.
