While our morphologies differ significantly we are forced to use chairs and armchairs produced in one size.
The creation of a custom-made seat based on the user's measurements will allow us to have a height and depth of seating perfectly adapted to the user's morphology.
Benefits of an adapted sitting posture
1- Thanks to an adapted seat depth, the back rests on the backrest cushion; the column retains its natural "S" shape.
2- The height of the armrests is high enough to sit upright and low enough not to create tension in the shoulders.
3- Thanks to a seat depth and seat height adapted to the leg segments, the pressure on the seat is ideally distributed.
4- The front of the seat does not press against the popliteal fossa and therefore does not hinder venous return; in a resting phase, recovery is faster.
Consequences of sitting in an oversized chair
A user whose leg segments are smaller than average in size will sit poorly in a one-size chair. The following problems can be observed:
1- Pressure of the seat against the popliteal fossa impeding venous return.
2- Pressure is poorly distributed, high at the front of the seat and low at the back.
3- When the seat is too deep, the back no longer rests against the backrest, the pelvis pivots and the back becomes rounded.
4- The lumbar hollow disappears, the spine loses its natural S-shape.
5- The armrests are too high and the shoulders are under tension. Muscle tension can result at the level of the cervical vertebrae.
Poor posture sitting in a chair that is too small in size
A user whose leg segments are larger than average is sitting poorly in a one-size chair. The following problems can be observed:
1- Over-pressure at the back of the seat, in relation to the ischium and sacrum.
2- The armrests are too low and do not play their supporting role properly.
