Shin built the Whale Chair using a combination of bent plywood and stainless steel to mimic the characteristic features of a whale's tail are defined through the smooth curves of the backrest.
Stained with Sumi ink, an east Asian ink typically used for calligraphy and brush painting, the heavy grain beech plywood was used to reinforce the whale motif and mimic the texture of whale skin.
To achieve the whale-like silhouette, the chair's wooden elements are divided into three individual pieces. The fin backrest is split in two and held together by steel piping, while the seat is designed to comfortably surround its user.
