Biblio Aero armchair, tailor-made

The width of the seat is equal to the width of your hips plus 2 to 5 cm. To measure it, sit on a flat surface, place two parallel blocks against your hips, measure the distance between them and add 2 to 5 cm.

To measure the depth of the seat, sit on a flat surface.

1. Measure the distance from the wall to the recess at the back of the knee.
2. Remove about 4 cm to get the seat depth measurement of the chair.

Correct measurement of the seat depth will result in better weight distribution over the entire seat, better blood circulation and therefore greater comfort.
It is important that the seat is not too deep so that it does not rest on the popliteal fossa at the back of the knee, which would hinder venous return.

To measure the height of the seat
1- Sit on a surface that is high enough so that your feet do not touch the floor.
1. Add books under the feet so that :
- the front of the thigh rests on the front of the seat (no hand should be able to pass through).
- the feet are no longer in the air
3. Measure the distance from the underside of the heel to the seat

If the seat is too high, the knees are up and the supports are more important at the bottom of the seat; the sitting position is quickly painful.
If it is too low, the feet are not on the floor and the user slides forward.

To measure the height of the backrest sit on a flat surface. You can choose between 3 types of backrest.
Classic backrest (Figure 1)
Pinch a pencil under the armpits and measure the height of the seat with the pencil.

Mid-high backrest (Figure 2)
Measure the height from the seat to the shoulder blades or base of the cervical vertebrae.

High backrest (Figure 3)
Measure the height from the seat to the rearmost part of the head.
