Chair and Table Sizes in Schools

Two students at Ardnashee School are working at a table on wheels while sitting in light blue cantilever chairs.

Sit well
at school

You can't do without sitting. Sitting is one of the basic human postures - and an important one at that. We can relax while sitting, but we can also concentrate well and are capable of peak mental performance. An important prerequisite for learning.

This posture has fallen into disrepute because we overdo it. Today, we sit far too much and we sit too statically. Even children suffer health problems from sitting too much and are unable to develop as they should. This applies to motor skills as well as social behaviour and cognitive performance.

A good school workplace can prevent this. This is important:

The chair and table must be the right size.
The chair should promote ergonomically good and dynamic sitting.
The workstation should be designed in such a way that frequent changes of posture and movement are encouraged.

Which seat size?

Chairs and desks are like shirts and trousers: the right size is crucial for a good fit. What ready-made sizes are for clothing, size classes are for school furniture. They are set out in DIN EN 1729, ‘Furniture - Chairs and tables for educational institutions’.

The standard distinguishes between seven size classes, which are colour-coded. The decisive factor is the height of the pupil. More precisely: the length of the lower leg, measured from the heel to the hollow of the knee. The seat height is derived from this.

In inter-year groups, the level model of our student chairs helps to ensure that all children sit ergonomically at the same table height.

Allocation of size classes for school chairs according to DIN EN 1729

Customise chair and table

The seat height is correct when the pelvis is slightly above the knees and the feet are flat. The pelvis is then erect and the spine can move freely. The thighs rest loosely on the seat. The angle between the thighs and torso is slightly open, allowing the blood to circulate freely.

The appropriate table height is derived from the sitting position: If the forearms are placed on the table top, the elbows should be two to three centimetres below the edge of the table.

Size of the seat shell

However, the seat height is only one dimension. The width and depth of the seat shell as well as the height and radius of curvature of the backrest are also decisive. Minimum requirements are also specified in DIN EN 1729.

VS goes beyond these minimum requirements with its student chairs. Thanks to the large selection of seat shells - S, M, L and XL - the chairs can be customised to individual body dimensions.

Dynamic seating

The best sitting posture is always the closest one. Ergonomically recommended chairs are therefore not just the right size. They also support dynamic sitting, in which the sitting posture changes constantly and intuitively. This ranges from barely perceptible micro-movements to visible shifts in body weight, for example when changing from the rear resting posture on the chair to the front working posture.

3D rocking function

To support dynamic sitting, the chair needs a freely movable seat surface that can tilt forwards, backwards and sideways - as is the case with the patented 3D rocking function from VS. This allows the seat to follow the many small movements of the pelvis, which has a positive effect on the functional unit of pelvis, legs, spine, shoulders and head. This benefits health as well as alertness and performance.

Back-friendly furniture for teachers

‘Like no other part of our body, the back is dependent on us constantly moving it,’ says movement scientist Dr Breithecker.

Together with him, we have therefore developed furniture that is tailored to the needs of teachers: Chairs that encourage dynamic sitting and thus relieve and activate the back at the same time; and desks that invite people to work standing up or sitting down.
