Short answer: no, you don’t always need a formal diagnosis to get an ergonomic chair — especially if your back pain is affecting your ability to work.
Longer answer: it depends on how your pain affects you at work, not just what it’s called.
Let’s break it down.
Back pain at work: diagnosis vs impact
A lot of people delay asking for help because they think:
“I can’t ask for an ergonomic chair unless I’ve been diagnosed with something serious.”
That’s not usually true.
In work and ergonomics contexts, impact matters more than labels.
You might experience:
-
Lower back pain from sitting for long periods
-
Pain that builds after 20–30 minutes at a desk
-
Sciatica or nerve pain made worse by sitting
-
Fatigue or stiffness that affects concentration
-
Pain that eases when you stand, move, or change posture
None of these require a formal diagnosis to be real — or to justify better seating.
Your answer at this point lies in Emotion Office who offer a free chair assessment from a qualified professional Ergonomic Assessor. This is a 15-20 min Whattsapp video call, we will then recommend a chair based on the outcome.
When you don’t need a diagnosis
You often do not need a diagnosis if:
-
Your pain is clearly linked to prolonged sitting or desk work
-
Your current chair lacks adjustability or proper lumbar support
-
The pain affects how long you can sit or work comfortably
-
Adjustments would reduce pain and improve productivity
In many workplaces, an ergonomic chair is considered a reasonable adjustment, not a medical intervention.
Employers are usually allowed to act on:
-
Reported symptoms
-
Occupational health advice
-
Ergonomic assessments
-
Functional difficulties (what you struggle to do)
Not just medical paperwork.
When a diagnosis might help
A diagnosis can be helpful — but it’s not always essential.
It may strengthen your case if:
-
You have a long-term or fluctuating condition
-
Your symptoms are complex or severe
-
You’re applying for funding (e.g. Access to Work)
-
Your employer requests additional evidence
Common diagnoses that often come up include:
-
Chronic lower back pain
-
Sciatica
-
Disc issues
-
Arthritis
-
Musculoskeletal conditions
But again: the key factor is how the condition affects your work, not the diagnosis itself.
Do you need a diagnosis for an Access to Work ergonomic chair?
This is one of the most searched questions — and one of the most misunderstood.
The important bit:
👉 Access to Work does not always require a formal diagnosis. The whole point of access to work is to get people working, so if you unable to work or your work is impaired then you can contact ATW on 0800 121 7479.
What they focus on is:
-
Whether you have a disability or health condition (including long-term pain)
-
How it affects your ability to do your job
-
Whether support (like an ergonomic chair) would reduce disadvantage at work
In assessments, the language that matters is functional, for example:
-
“Pain increases after prolonged sitting”
-
“Current chair does not support sustained desk-based work”
-
“Symptoms reduce with appropriate lumbar support”
-
“Discomfort impacts concentration and stamina”
A GP note, physio letter, or occupational health report can help — but a diagnostic label is not always required.
Ergonomic chairs: prevention vs treatment
Another common myth is that ergonomic chairs are only for people with diagnosed conditions.
In reality, ergonomic chairs are often recommended to:
-
Prevent worsening pain
-
Reduce flare-ups
-
Support sustained sitting
-
Improve posture and movement variety
Waiting until pain becomes severe or formally diagnosed can actually make things worse.
Early ergonomic support is often seen as reasonable, proportionate, and preventative.
Ergonomic chairs have many different functions that can be used to support you, such as memory foam seats and backs, sacral pumps, thoracic pumps, coccyx cout-outs, the list goes on. Bespoke sized office chairs can be purchased from Emotion Office.
What matters more than a diagnosis
Whether you’re talking to your employer, an assessor, or applying for Access to Work, these things usually matter more than a diagnosis:
-
How long you can sit comfortably
-
What tasks make pain worse
-
What adjustments reduce symptoms
-
Whether your current chair is adjustable and suitable
-
How pain affects productivity, focus, or fatigue
An ergonomic assessment (formal or informal) is often more useful than a medical label.
Key takeaway
You do not usually need a diagnosis just to get an ergonomic chair, you can start with a free assessment and explain your issues.
What you do need is:
-
A clear explanation of how sitting affects your pain
-
Evidence that your current setup isn’t suitable
-
A reasonable link between the chair and improved ability to work
If pain is affecting your work, that’s enough to start the conversation.
