Taking the right measurements

Measuring for an Ergochair

Measuring for an Adapt chair from Ergochair is incredibly quick and easy to do. Please don’t worry if you don’t have all or any of these measurements. Please just send us what you have and we can advise what to do next. The article will quickly take you through some ideal measurements to ensure that the chair will accurately fit the user.

1 – Popliteal Height:

Why is it needed? Popliteal height is crucial to ensure that we can get the correct gas stem height to ensure the seat height range covers the level you need to be at when setup correctly at your desk.

How to measure it? Firstly you need to raise or lower the chair so that when the users elbows are bent at 90 degrees the forearms gently rest on the surface of the desk. Please note that if this position raises the feet off the floor, you are likely to need to use a footrest in the future.

In this position, please measure from the surface of the floor to the crease behind the back of the knee when the knee is bent at 90 degrees. When taking this measurement please ask the user to wear the footwear that they normally wear while seated at their desk. 

2 – Thigh Length:

Why is it needed? It is important that the seat pan fully supports the thigh without butting into the  back of the calf. To enable us to ensure that the seat pan will be able to do this we need to know the thigh length.

How to measure it? Whilst the user is sitting on a standard office chair, measure from the back of the buttock to the back of the knee.

3 – Lumbar Height Measurement:

Why is it needed? This measurement is used to ensure that the inflatable lumbar support is placed at the ideal height for the user.

How to measure it? While seated, measure from the top surface of the seat pan to the deepest point of the lumbar arch.

4 – Hip Width Measurement:

Why is it needed? This allows us to ensure that your seat will be made to the right width for you.

How to measure it? Ask the user to perch on the chair and from behind measure the width of the hips at their widest point across the seat pan.

5 – Seat to Shoulder Measurement:

Why is it needed? This is to ensure that the backrest is made to the correct height.

How to measure it? Whilst the user is perching on the stool, kneel behind them and measure the distance from the seat pan to the top surface of the shoulder.

6 - Seat Surface to Underside of the Arms:

Why is it needed? This measurement is used to ensure the armrests will have an appropriate height range that will adequately support the upper limbs.

How to measure it? While seated, ask the user to bend their elbows at 90 degrees and measure the distance from the seat pan surface to underneath the forearm.

 

7) Inside Elbow Width:

Why is it needed? This measurement is used to help ensure the armrests are positioned correctly under the arms and will not be too wide or too narrow.

How to measure it? With the elbows bent at 90 degrees, measure the distance between the inner surface of the forearm to the opposite forearm.

 

8) Shoulder Width:

Why is it needed? This measurement is used to help ensure the backrest is wide enough.

How to measure it? Measure the distance from the edge of the left shoulder to the edge of the right shoulder.
