Office Health and Safety laws govern employers to be responsible for not only the safety of staff in the workplace but also their health. While covering a multitude of guidelines for varying scenarios, it also includes the understanding ergonomics in the workplace.
What is Ergonomics?
Ergonomics is the science concerning the ‘fit’ between people and their work, it’s there to make sure that people and their health comes first.
Now don’t panic, this isn’t going to be a complete Health and Safety post… we’re just offering some advice to help improve your working day by explaining the correct desk and seating heights.
In turn, this should start to improve your posture, relieve some back stress, and help you relax and enjoy your work a little bit more.
The Perfect Sitting Position
This is a little deep but worth the read! In 2006, researchers at Scotland’s Woodend Hospital used motion MRI scanning on volunteers to try an identify the best and worst seating positions for our backs.
Unlike a normal MRI scan where you’re not allowed to move, this one was designed to scan the moving patient in a seating position. During the scanning process they were asked to sit in 3 alternative positions:
- Slouching (that’s me) – hunched forward, feet touching the floor
- Upright (not me) – 90 degree angle, feet flat on the floor
- Relaxed (err… never), reclined backwards at 135 degress, feet flat on the floor
The scan measured their spinal angles, spinal disk heights and movements during and between the different positions. The research looked at strain on spinal disks as undue strain causes a disk to move and sometimes set it out of place.

The results found that:
- Slouching – caused less disk movement than upright, high rate of wear and tear
- Upright (90 degrees) – caused the disks to move the most
- Relaxed (135 degrees) – caused the least disk movement
In short then, sitting upright is worst while sitting relaxed at 135 degrees is best for our backs!
The reality check is that doing anything in excess is bad for you and that obviously includes sitting down for long periods whatever the angle! Best practice is to get up and move around, but we already know that don’t we?
Need a 135 Degree Capable Office Chair?

For example, this Axia Operator Chair (now SOLD!) at £125.00 is elegant yet robust and offers an array of dynamic seating adjustments allowing the user to fully adapt it to their personal comfort.
Or, how about the classic Steelcase Leap Chair (now SOLD!) at £120.00, one of the most ergonomic office chairs in the market today?
These are and feature a dynamic seat that relieves the pressure from your lumbar vertebrae when reclined ensuring your back is fully supported at all times.
Setting The Perfect Office Desk Height
An incorrect desk height is also unhealthy for us and a simple way to find the perfect desk height is to carry out these steps:
- When sat at your desk, rest your arms, keeping your elbows at a 90 degree angle
- If your hands rest neatly on the desk and they are comfortable then your desk is at the perfect height
- If your elbows are raised too high or they hang too low then you need to readjust your position because it’s not right!
