Psychology says people who constantly adjust their office chair may be highly sensitive to their physical environment

For some office workers, sitting down is only the beginning. Within minutes, they may raise the chair, lower it, move the seat forward, lean the backrest, change the lumbar support and then adjust everything again after an hour. To colleagues, this can look like fussiness or an inability to settle. But psychology and ergonomics suggest something more interesting may be happening. People continuously respond to physical comfort, posture, bodily sensations, task demands and perceived control over their environment. Research has found that physical comfort and the desire to change posture are important reasons people adjust office chairs, while cognitive barriers can determine whether workers know how and when to make those adjustments.

Psychology Says Chair Adjustments Can Be About Perceived Control

One useful psychological concept is perceived control, the belief that you can influence what happens around you.

In a workplace, employees cannot control every external factor. They may not choose the office temperature, noise levels, lighting, desk position or who sits nearby. But an adjustable chair offers something they can control immediately.


Research on office environments has found that personal control over physical workplace features can influence how employees experience distractions and perceive their job performance. This means repeatedly adjusting a chair may sometimes provide a small but meaningful sense of environmental control.

A worker who cannot change a noisy office might at least change the chair height or backrest and create a position that feels more manageable.

Ergonomics Explains Why People Keep Searching For The Right Position

There is also a straightforward physical explanation. Sitting is not a completely static activity. The body continuously responds to pressure, muscle fatigue, posture and movement. Research examining office-chair design has found that different seat and backrest configurations can affect comfort, posture and adjustment preferences.

A 2019 study of office workers found that physical needs such as increased comfort and postural change were strong drivers of previous chair-adjustment behaviour. Interestingly, many workers knew about only a small proportion of the adjustable functions available on their chairs.

So someone who keeps changing the chair may simply be responding to the physical feedback coming from their body.

Body Awareness Can Make Small Discomforts Harder To Ignore

Some people appear particularly attentive to small changes in physical comfort. This can be understood through interoception and body awareness, although it would be too strong to diagnose someone from chair behaviour alone.

Interoception refers broadly to the perception and interpretation of signals arising from inside the body. In an office setting, subtle sensations such as pressure behind the thighs, tension around the lower back or an uncomfortable shoulder position can become signals that prompt a person to move.

For example, one employee may continue working despite a slightly awkward sitting position. Another may immediately notice it and adjust the chair.

Neither response automatically indicates a personality trait. They may simply differ in how strongly they notice or respond to bodily discomfort.

Psychology Says Frequent Adjustments Can Become A Habit

Repeated chair adjustments can also become habitual behaviour.

If someone routinely changes the chair after arriving at work, the sequence can eventually become part of their normal workplace routine. The cue may be sitting down; the behaviour is adjusting the chair; and the immediate consequence is a temporary feeling of greater comfort or control. This creates a simple behavioural loop.

The person may eventually reach for the chair controls almost automatically rather than consciously deciding, “I need to adjust my chair now.”

That also explains why someone may adjust the chair repeatedly even when the difference between settings is relatively small.

Task Demands Can Change What Feels Comfortable

The “perfect” chair position may also depend on what a person is doing.

Someone typing for hours may prefer a different position from someone reading documents, attending a meeting or leaning toward a second monitor. Research examining chair characteristics and different office tasks has found that task type can influence preferred backrest movement and chair settings. This makes repeated adjustment less mysterious.

A journalist typing rapidly may move closer to the desk. During a video meeting, they may lean back. While reading a long document, they might change the backrest angle again.

The chair is responding to the person's changing relationship with the task.

Adjusting The Chair Can Actually Improve Comfort

There is an important reason not to dismiss this behaviour as unnecessary. A 2022 randomized controlled trial found that workstation adjustments reduced postural exposure and perceived discomfort among office workers.

Another ergonomics intervention study found that training combined with an adjustable chair increased workers' perceived control over their physical work environment and improved ergonomic behaviour compared with controls.

So the colleague who spends several minutes adjusting the chair may actually be doing something useful.

At the same time, research on chair design shows that even improved posture does not necessarily eliminate all sitting-related pain or discomfort.

It Does Not Automatically Mean Someone Is A Perfectionist

It is tempting to say that a person who constantly adjusts their chair must be a perfectionist, controlling or unusually particular. Psychology does not support such a simple conclusion.

The behaviour could reflect physical discomfort, task demands, habit, body awareness, ergonomics or a preference for environmental control. In some people, several of these factors may operate simultaneously.

The more revealing question is therefore not, “Why can't this person leave the chair alone?”

It may be: “What is the person trying to regulate, their body, their comfort, their environment or their sense of control?”

That makes the seemingly mundane act of adjusting an office chair a surprisingly interesting example of how psychological and physical processes interact at work.

FAQs

Why do some people keep adjusting their office chair?

They may be responding to discomfort, posture, changing work tasks, body sensations or a desire for greater control over their physical environment. Research specifically identifies comfort and postural change as important reasons for chair adjustment.

Can adjusting an office chair actually improve comfort?

Yes. Research has found that workstation adjustments can reduce postural exposure and perceived discomfort among office workers.
