How to choose the proper seats as well as the tables and desks
A few specifications
Tables and Desks Clearance: For seated work, the table should provide about 20 cm of clearance. This is the space between the top of the thigh and the underside of the table. • Some chairs have a flexible backrest allowing movement, while providing good back support. • The balls should be periodically inflated, and varying inflation provides various seat heights. • The child must use seats to support his back, especially the lower back. • Bistro height stools, often used at standing desks, should have a footrest bar. • Chairs provide four different seating positions: Oriented towards the front or the back, or seated on the left or right side, preventing twisting of the torso.
Ergonomics being primordial, the choice of seats for a class is always a major challenge. In flexible setting, the diversity of the types of seats further complicates the task! See below for basic information that applies, no matter the type of seat as well as specifications for each. Seated position No matter the type of seat, an ergonomic seated position requires the feet to be flat on the ground and that the knees be bent at 90˚. The seat height corresponds to the height from the floor to the crook of the knee. The following table is based on recommendations from various sources and constitutes a reliable guide. However, measuring the child ensures the best possible adjustment.
Hint from B 2 Whether working sitting on the floor, a chair, a stool or standing, the work surface must always be at elbow height.
The following table constitutes a good guide.
