Why it is renowned
River Stones are the design Gonge’s Hilltops grew from: Henrik Gonge used them as the template for the taller set that the Victoria and Albert Museum now holds, and the museum dates them to 1997.1
The story
The design studio HarritSorensen designed River Stones for Gonge in 1997.1 They are modelled on stepping stones in a river: each is a triangle whose three sides slope at different angles, so a child can choose an easier or harder way up.2 Children lay them out as a path and jump from stone to stone without touching the floor.2 A rubber rim underneath keeps each stone from sliding and protects the floor.2 Gonge sells them as model 2120, for ages two to fifteen and a load of up to 100 kilograms, in a later version that stacks for storage.2
