Charles Darwin is credited as one of the earliest innovators of the office chair, adding wheels to his study chair to access specimens more easily. Office chairs evolved in the 19th century to increase worker productivity by allowing longer periods of sitting. Ergonomics became an important design consideration in the 1970s, making chairs more comfortable and adjustable. However, chairs often fail to accommodate the wide range of human sizes. Ergochair measures individuals to customize chairs with dimensions like thigh length and back width for optimal fit and support.

2. According to certain sources, one of the earliest innovators of the office chair was Charles Darwin, who put wheels on the chair in his study in order to get to his specimens more quickly From the mid-nineteenth century, office chairs were then designed to increase productivity in ‘clerical’ employees, enabling them to sit at their desks for longer periods In the 1970’s ergonomics became an important design consideration. Office chairs evolved to be more comfortable and also adjustable. However, one major factor still gets largely overlooked today… ….People and their infinite range of sizes!

4. How much do you interact with your office chair?

5. Would you wear shoes that didn’t fit you? “there is now a wealth of evidence based on research into ergonomics in the workplace over the past 40 years suggesting that a huge number of musculo-skeletal disorders can be eased or potentially even avoided by using a correctly fitting office chair” The very basis of Ergonomics centres around ‘fit’ between humans and the objects we interact with Which is why, at Ergochair, nine years ago, we decided it was time to start measuring people in order to fit the office chair around them

6. 1) Thigh length 2) Shoulder height 3) Lumbar height 4) Hip width 5) Knee height 6) Back Width

7. Ensuring that the basic size of the chair template conforms to the individual is vital... Using these dimensions, the chair is ‘Cut to Fit’ 1) Seat depth – optimum support to thigh length 2) Backrest height – check thoracic support 3) Lumbar support - coincides with the individual 4) Seat pad width and armrest width 5) Seat height in relation to desk height 6) Backrest Width – no squeezing!
