The spirit shell was designed by Hajime Oonishi for Houtoku, the Japanse licensee of Artifort. Artifort admired the straight, practical and comfortable form. For a long period Artifort sold the Spirit as a multiple seating (f.i. Schiphol Airport Amsterdam).
A new base has been designed. The Spirit Stack, as it says, is stackable! Stronger and more up to dat than ever!
