After starting school, most children study in the classroom sitting at their desks. It’s easy to recognize that most children have poor posture. Ensuring that the backrest provides proper support to children's backs allows posture to be corrected. This is why one of the main features of the Ringo chair is an adjustable backrest. Simply by moving the chair’s armrests, children can adjust backrest height, seat depth and armrest height. What’s more, the Ringo chair also has fixed-cylinder, sit-brake casters and a footrest for extra concentration. The shape of the Ringo chair creates a friendly studying atmosphere.
