In the UK, the average adult spends around 9.5 hours a day sitting down. That’s more time than most of us spend sleeping each night! So, it’s no surprise that one of the most common questions our seating specialists get is about improving and maintaining posture.
“Sit up straight, or you’ll get a bad back!” is a phrase almost everyone will have heard at some point in their life. But posture is about more than just your back. The whole body is involved in maintaining good posture and poor posture can lead to problems with everything from your breathing to your circulation. Plus, for people with disabilities especially, it’s not as simple as ‘sitting up straight’. Many people cannot sit upright without support or reposition themselves whilst seated.
In this guide, we look at what good posture really means and provide practical advice on how to maintain proper posture whilst sitting.

Good posture will mean different things for different people.
One reason UK adults spend so much time sitting is because many people work office jobs that require them to sit at a desk. For this reason, a lot of postural advice focuses on maintaining good postural whilst sitting at a desk:
The ideal sitting position for an office worker will:
However, someone with a spinal abnormality will not necessarily be able to achieve the same postural positioning as someone without any spinal issues.
To give an example, the ideal posture for someone with cerebral palsy who spends most of their day sitting in a care chair will not follow these guidelines written for an office worker sitting at their desk.
Bearing this in mind, Pauline Pope, a research physiotherapist, set three key criteria for determining good posture for an individual:
If you’re not an OT or physiotherapist that specialises in seating and posture, these criteria can seem quite complicated. But really, they just acknowledge that having one set standard for good posture won’t work for everyone.
Here are some questions you might ask when assessing someone’s posture using these criteria:
To sum it up, good posture is all about protecting the overall health and wellbeing of someone when they are sitting down.

Now let’s move onto some tips for improving and maintaining good posture whilst sitting!
At first, poor posture will present as discomfort, aching and sometimes a slight stoop or lean.
If caught early enough, this can often be corrected using physiotherapy exercises and supportive seating. For example:
You can get more advice on correcting mild postural problems on the NHS website.
Unfortunately, over time poor posture can develop into permanent spinal deformities and postural abnormalities. These cannot be corrected. Instead the focus will be on using specialist seating to prevent the problem from getting worse.
We have some guides to the best seating for different spinal abnormalities if you’re looking for more specific advice:
As the saying goes, prevention is better than cure. It might be a cliché but it’s definitely true when it comes to posture.
For many people, following the recommendations for proper sitting position (outlined in the first section of this guide) whilst at work and avoiding slouching on the sofa at home will be enough to maintain good posture.
However, for people with disabilities who are at risk of developing postural abnormalities, it is important that their OT and other care professionals work with them to find the right chair to help them maintain the correct seating position.
If someone cannot sit up without support or reposition themselves, then specialist seating which can be adjusted to fit their body is the best way to maintain their posture.
Here are some tips for providing the correct support for each part of the body whilst sitting:
Avoid neck ache by supporting their head properly whilst they’re sitting. This will allow them to breathe and swallow effortlessly.
If the user requires head support, ensure the neck is kept straight, and the chin slightly elevated, to make sure they are stable. This position also allows the user to interact with the environment comfortably. Make sure you consider the shape and firmness of the support.
Look for a headrest that you can adjust to accommodate someone’s head position i.e. by changing the shape of the head cushion or by resizing it by adding/removing padding.
Don’t be tempted to add another cushion to fill the gap between the neck and the headrest. This forces the head forward.
The chair’s armrests should fully support the user’s arms, without pushing up the shoulders. If the shoulders are pushed up, it indicates the armrests are too high.
You also need to avoid setting the armrests too low as this can cause the user to hunch forwards.
It is also important that the user does not have to control their trunk position with their arms for long periods of time, as this will put pressure on the neck and shoulders.
Make sure their back is resting fully against the back of the chair. Any gaps between the user and the chair back mean their weight will be concentrated onto smaller contact areas. This increases pressure, and means they will have to work harder to maintain the position they are sat in.
To avoid this, check for gaps behind the pelvis area, at the small of the back and under the shoulder blades. Adjust the size of the chair to fill the gaps, using lateral supports if necessary, to gain full contact with the chair.
People often think the back is the most important thing when it comes to posture. We’ve already discussed how the entire body determines your posture whilst sitting, but good posture actually starts with the pelvis!
If the pelvis isn’t positioned properly, then the whole body ends up misaligned. Ensuring the seat depth and width properly fit the user are key for supporting the pelvis.
For those with low body tone, it may be beneficial to start using supporting accessories such as belts, pommels, wedges and lateral supports, to ensure the patient maintains good posture and comfort.
A 4-point belt can be particularly helpful for keeping the pelvis aligned for someone at risk of sliding forward in their chair.
Positioning their legs in the right way will stabilise the pelvic position and improve circulation to the lower legs.
For best results, adjust the leg rest to keep knees at the same height as the hips. This increases stability and keeps the soft tissues on the underside of their thighs supported but not overly compressed.
The most important thing when it comes to foot support is ensuring the feet rest fully on the floor or a footplate. Without this support, their body weight will not be properly distributed.
Avoid putting too much pressure on their heels and support the calf muscles fully by resting their feet lightly on the footplate.
As you can see, there are many factors to consider when it comes to posture and seating!
We hope this guide has explained what good posture means and given you some ideas for improving and maintaining good posture.
However, each individual will have different needs which affect their posture and seating requirements. We always recommend getting a professional seating assessment.
