I like the shape of a mushroom. So of course I fell in love with both these lovely mushroom stools when I first saw them. The one on the left is Fungo by Paola Navone for Riva 1920. It is made out of solid cederwood for the base, and walnut for the seat.
The one on the right is Le Champignon by Hanke for kids. Would fit perfectly in a kids room.
