Now a well loved Sheffield Landmark, the Rivelin Chair came into existence as a result of a play project I led in 2009. It's in the river because that where the local children I talked to decided the structure should go, and Jason Thomson, the artist, was excellent at interpreting a brief that would encourage fun and reflective play. 15 years on, you can still hop on the stepping stones to the island, sit back and enjoy nature. It has completely fulfilled it's purpose.
