Woodcrest Chairs are scaled so that children can sit with their feet flat on the floor. The relationship of seat to table is another important consideration. An 20cm height difference from seat to table will accommodate most children well.
When selecting chairs for your centre, consider the height of your tables as well as the ages of the children in your group.

Seat width  39cm
Seat depth  37cm
