CHILDREN BECOME PEOPLE.
Children often grow faster than you think. That's why it is especially important to take into account in spatial planning that a first grader will grow up to 32 inches taller before he or she is fully grown. If you check every six months whether the desks and chairs are still the right height for all the pupils, you are on the safe side. Is the foot posture still correct? Are the elbows level with the table surface when sitting upright?
A2S furniture offers six size divisions that are easy to distinguish thanks to their colored markings. For all students and adults who need it, there is also an extra size with an extra-wide seat. You can always be sure that everyone is sitting comfortably - regardless of their size.
HOW TO CHECK IF THE CHAIR FITS THE STUDENT.
The feet must be flat on the floor. The seat height must be adjusted so that there is a bend angle of 90 degrees at the knee joints (never higher!).
There must be no pressure between the front edge of the seat and the underside of the thigh. There must also be sufficient clearance between the back of the knee and the front edge of the seat.
If the upper arm hangs vertically down the body, the forearm must be able to rest on the tabletop in such a way that the elbow is at the same height as the tabletop - or slightly lower.
The backrest should support the back below the shoulder blades in the listening posture and at the edge of the pelvis in the working posture, so that sitting upright is effortless.
Teachers are not only responsible for the social and intellectual development of their students, but also their health. Therefore, they should pay attention to the correct sitting posture of their students and help assign them the right desks and chairs.
Since every student has different body proportions, the sizes assigned by the industry based on age can only be guidelines and should always be supplemented by an individual seating sample.
For the sake of simplicity and also for visual reasons, classrooms are far too often equipped with a uniform table and chair size. However, since there may be size differences of up to 20 inches within the same class, there must also be different sizes of furniture.
Many children starting school need size 2 furniture, but unfortunately is often only found in preschools, because many school districts find it too expensive to buy a size that can only be used by a small student population.
Children grow quickly. A chair that was appropriate at the beginning of the school year may be too small after the winter break. Therefore, a seat test should be conducted at least every half year and - if no height-adjustable furniture has been purchased - sufficient replacement furniture must be available.
