• Ringo is for seven to twelve year old children who start study on their own desks and chairs. 
  • What if young kids sit on a normal desk and chair?
  • They would usually stay either one of the two below, which might harm their spine.
  • Then how about adjustable backrest moving back and forth?
  • Small kids can sit properly with short seat depth, and tall kids with long seat depth.
  • These are the early sketches from above concept.
    Ringo can adjust not only the backrest height and seat depth
    but also the armrests height at once by only moving armrests.
  • All dimensions of Ringo are based on certified data from Korean Agency for Technology and Standards.

  • 1:1 scale mock up
  • I verified the dimension of Ringo to let 7-year-old children sit on the prototype.
  • Feature #1: Adjustable Backrest
    Ringo's backrest can be movable diabonally by side lever. It has four steps, and an indicator helps you recognizing the current step.
  • Feature #2: Replacable Backrest and Seat
    Customers can disassemble the backrest and seat easily to change when it is polluted.
  • Feature #3: Closely Positioned Seat Height Lever
    The seat height lever is closer to user than normal chairs, and it is for small children.
  • Feature #4: Lever for fixing the chair not to rotate
    It helps children to keep their posture properly and safe.
  • Feature #5: Sit-Brake Casters
    The Sit-brake casters work by frictional force from user's weight. When Children sit on the Ringo, it stops to move to concentrate on their study.
  • Feature #6: Optional Footrest
    Small children under ten-year-old may hard to sit on the chair with normal desk. Optional footrest can help them and it can be detached easily.
  • Ringo passed several data of BIFMA test. Also, Ringo consists plastic most parts for weight reduction.
  • Ringo has two types of upholstery, mesh and artificial leather(PU).
    Mesh gives ventilation and artificial leather provides easy cleaning.
  • Ringo matches weill in children's room. These photos are from users' blog.
