This 11-1/2" red Brite Kids Chair is generally appropriate for five year old children often for use with Brite Kids Tables (sold separately) that come in seven shapes and sizes to fit any area. Chair was designed with both the teacher and student in mind. Steel frame supports from the bottom, allowing an adult weighing up to 300 lb. to use the chair in order to work closely with the students. Plastic boots on the four chair legs protect floor surfaces. Shield-shaped cutouts on the back of the chair allow proper sitting posture and provide a handle for easy mobility. Chairs stack eight high safely. Tables, which are adjustable from 14-1/2" to 24-1/2" high, should generally be set at 20" high for use with the 11-1/2" chair. If a child's feet are flat on the floor and their knees are bent at a 90 degree angle, you have the correct chair for ergonomic, comfortable seating.
