Chair, Size 3, R82 Scallop

This is a Chair, Size 3. It was designed by R82. It is dated 2016. Its medium is shell: polypropylene; cushion: polyester and polyurethane; straps: polypropylene.

Designer Keira Gwynn originally created this simple, portable, and versatile seat as a student project for use as an indoor or outdoor aid in floor sitting or to add extra support attached to a chair. By enclosing the seat around the child’s pelvis and trunk, it provides stability without preventing movement, providing sensory feedback that creates a sense of calm and relaxation.
