Chair armrests wrong height: Sit back and check whether your elbows and forearms rest comfortably while your shoulders stay relaxed. Armrests may be too high if you shrug to use them, or too low if your arms hang down without useful support.

Sitting back in the chair gives you a better starting point for checking the fit. If you live with a disability, use the chair’s designed adjustment where available, following its instructions. The aim is comfortable arm support without having to change your sitting position just to reach it.

Comfort while resting is only part of the check: the armrests also need to be useful when you sit down or stand up. That second job is easy to overlook. A setting that feels comfortable during a quiet sit still needs to suit how you get into and out of the chair.

1. Chair armrests wrong height: Notice what your shoulders and arms are doing

Settle into your usual supported sitting position before judging the armrests. Let your shoulders relax and notice where your elbows and forearms meet the supports. You are looking for a comfortable resting place, not a height that makes you hold your shoulders up or reach down.

Armrests that are too high may leave your shoulders hunched while your arms rest on them. Too-low armrests may leave your arms unsupported or your shoulders drooping towards them. These are useful signs of a possible mismatch, rather than proof that a particular injury or condition is developing.

Compare how you feel when you first settle with how you feel during a longer sit. Notice whether the armrests remain comfortable or whether you keep shifting to find support. A chair can seem suitable at first without being a good match for your usual sitting routine.

The height also needs to work with the rest of the chair. Raising or lowering the seat simply to reach the armrests changes your sitting position too. Keep the whole fit in mind rather than treating the armrests as a separate problem.

This guide to choosing a chair explains shoulder position, arm support and help with standing.

There is no single armrest measurement in this guidance that suits every person and chair. Your relaxed shoulder position, comfortable arm support and ability to use the chair are more useful checks than copying someone else’s setting.

2. Chair armrests wrong height: Adjust safely and check getting up too

With adjustable armrests, start with the adjustment the chair was designed to provide. Follow its instructions and check that the supports are secure and the chair remains stable before relying on them. Compare your arm and shoulder position again after changing the setting.

Then return to the overlooked detail: getting up and sitting down. Armrests should offer support for these movements as well as for resting. Consider your usual movement, but do not repeatedly practise a difficult transfer alone just to test a setting.

Fixed armrests offer fewer options. Loose padding, stacked cushions, homemade risers or changes to fixed supports are not a substitute for checking safety. A change that seems to solve the height problem may alter the chair’s fit or stability.

A different chair may be worth considering when fixed armrests cannot provide comfortable support. Before replacing a chair you rely on for mobility support, ask an occupational therapist to assess its fit. Persistent discomfort or difficulty getting up or sitting down also warrants that assessment.

An occupational therapist can look at your posture, how you move and the space around the chair. This guide to seating support explains comfortable arm support and seating assessment.

Related sitting difficulties may need different changes, rather than another armrest adjustment. Read about discomfort during longer sits when the problem extends beyond where your arms rest.

People Also Ask…

How can I tell whether my armrests are too high?

Raised or hunched shoulders while your arms rest on the supports suggest the armrests may be too high. Sit back and let your shoulders relax before checking. Where adjustment is available, follow the chair’s instructions and compare the support again rather than judging by appearance alone.

What suggests that my armrests are too low?

Arms that hang down without comfortable support, or shoulders that droop towards the armrests, suggest they may be too low. Notice whether you have to change your position to reach them. The aim is support for your elbows and forearms without having to reach down or lean towards it.

Can I add a cushion to correct the height?

A loose cushion is not a reliable way to correct an armrest-height problem. Raising your sitting position also changes how you meet the armrests and the rest of the chair. Avoid stacking cushions or improvising supports; ask an occupational therapist about a suitable adjustment when the built-in options do not help.

Should armrests help when I stand up?

Yes, suitable chair arms should provide support when you sit down or stand up, as well as while resting. Comfortable sitting alone does not confirm that the chair suits those movements. Difficulty using the armrests during transfers is a reason to ask an occupational therapist for a seating assessment.

Is a desk-chair armrest setting suitable for every chair?

No, desk use adds considerations that do not apply to every everyday chair. Armrests can restrict movement or stop you drawing close to a work surface. For an everyday supportive chair, focus on relaxed shoulders, comfortable arm support and how you sit down and stand up, rather than copying a desk setup.

When should I ask for a seating assessment?

Persistent discomfort or difficulty transferring is a good reason to ask an occupational therapist to assess your seating. An assessment is also useful when you depend on the chair for mobility support and its fit is uncertain. Explain what happens while resting and getting up, and which adjustments you have already tried.
