Furniture's size

Proper selection of furniture,s size is very important issue, mainly because of harm that bad choice might cause. Among other it can be:

  • establishment and deepening of posture defects,
  • vision defect (if the child does not keep proper distance from the top benches),
  • negative impact on the work of internal organs,
  • increased physical activity in a child,
  • high sense of tiredness, fatigue,
  • reducing the efficiency, speed and quality of work.


Good matching of furniture consists on that:

  • soles of the feet (in shoes) have over its entire surface touch the floor,
  • between the thighs and the plate of the table should be kept small space to move legs,
  • table height must be such that the top, if the arms are lowered, was on the level of the elbows,
  • the chair should support your back sitting in the lumbar spine, not reaching the blades.
