Release: August 2011 Market: South Korea, so far Price: approx. $200 http://us.aving.net/news/view.php?articleId=452389 Most children start to study sitting on the chairs with the desks after entering the school. However, we can recognize easily that children’s sitting postures are usually poor. If the backrest can be located right behind our children’s backs, children can keep a proper posture. For these reasons, Ringo has focused on the adjustable backrest. Ringo can adjust not only the backrest height and seat depth but also the armrests height at once by only moving armrests. Also, Ringo provides a fixed cylinder, sit-brake casters and a footrest for concentration. Last, Ringo’s shape is close to a character for friendly atmosphere to study. Read Less
Published:
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.
