The Wave Seat is a fun multi-positional chair to saddle, perch or sit. This stool grows with you for use with children to adults. The active core engagement stool evolves from a saddle-style seat with wobble base, to a perch seat, and full seating surface. The forward seat angle keeps legs engaged for active seating that supports upright posture and alertness. These chairs are intentionally designed for shorter periods of sitting, perfect for high-traffic spaces like libraries, common areas, outdoor classrooms, and places for quick conversations. Designed for everyday use in schools, homes or offices, these lightweight stools let you quickly rearrange workspaces. Easily circle up for discussions or pair with activity tables and desks for individual and collaborative work. Creative classroom seating supports different learning styles and empowers both students and teachers. These flexible seats provide freedom to move making it the perfect grab-and-go stool for taking the classroom indoors and out. When learning time is over, two seats nest together for compact storage to save valuable floor space. The streamlined one-piece plastic design features rounded edges and no hard corners for safety, comes fully assembled and is maintenance-free.
