Bell (stool chair) is a comfortable stool to use in various spaces such as home and office. The round bell-shaped volume is considered to be usable by children, adults, and even pets. Unlike ordinary stools, the stuffy lower part is opened to create an auxiliary space. This makes it a great place to store your luggage, support your paws or even make a great shelter for your pet. It serves as a great object in the interior while having versatile usability. It is possible to design a design that suits the user by selecting the wood top plate type for the use of the auxiliary table and various seat colors and body colors.
