The Four Tower with Two Bridges 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 step bridge offers graded access, each platform offering 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 the obvious play activity for e.g. children with physical disabilities, with a perfect distance of access point on ground level to egress point.
