The Four Tower with Wobbly Bridge offers a wealth of diverse climbing, crawling and sliding experiences. The diversity in play experiences make children come back again and again. The different bridges offer each their muscle and motor skill stimulating play event: the wackle bridge trains balancing skills, while each platform offer a point for a break or a meeting. The tunnel takes sliding or crawling through, both great for the cross-body coordination. This trains the cooperation between the left and right brain half which is necessary for later reading skills. The slide stimulates the spatial awareness, needed for navigating space, e.g. in traffic, securely. The inclined bridge with skid preventive floor details support less physically confident users. This is a supportive play activity for e.g. children with physical disabilities, with great distance of access point on ground level to egress point across the supportive, inclined bridge.
