fyt

Return to work, and stay well in work

Objective insight that helps people return to work, and stay there.

Fyt sits quietly in your work chair. It gives continuous, low-friction insight into sitting tolerance, static load and movement variety, so you can pace your return, notice early when work is getting harder, and change the job as well as your habits.

A simple truth

Returning is harder than leaving

People don't leave work because they lack motivation. They leave because work has become physically or mentally unsustainable.

Back pain, surgery, long COVID, fatigue and other long-term conditions can all reduce how long someone can sit and work. Stamina and confidence drop with it.

Without objective support for pacing, people commonly overdo it on a good day, relapse, and end up off work again. 148.8 million working days were lost to sickness or injury in the UK in 2025.

The missing data layer

People track heart rate, sleep and exercise. Nobody measures work tolerance.

What we measure

Not posture. Not perfect sitting. Work tolerance.

Sitting tolerance

How long you can sustain desk work, tracked day by day and week by week.

Static load

Unbroken periods without movement, which build strain during recovery.

Movement variety

Micro-movements and position changes while you sit.

Early warning

When your tolerance starts falling below your usual, so you and your supporter can act before a setback or absence.

  1. The thin Fyt sensor mat on an office chair seat

    Sit as normal

    The slim mat fits your existing office chair. Pressure and motion sensors pick up weight shift and movement. There's nothing to wear, no calibration and no exercise programme.

  2. The Fyt Today screen on the work computer

    Get gentle, just-in-time prompts

    When static load rises, a supportive prompt suggests a change of position or a short break. Prompts are easy to dismiss, and you choose the style.

  3. The Fyt progress screen with job adjustments marked on the trend

    Change the job, and see what helps

    With your consent, your practitioner sees high-level trends. Together you plan hours, breaks and workstation changes, log them, and see whether they worked.

The dashboard

One picture, shared by the people supporting a return.

Today screen: seated spells through the day, current spell against the plan, movement variety, an optional day check-in and sharing status

Today

  • Every seated spell, coloured as static load builds
  • The current spell against your agreed plan
  • An early warning when tolerance dips below your usual
  • An optional one-tap check-in: good, OK or hard day

Principles

What Fyt is, and what it isn't

Functional recovery, not generic wellness

The goal is sustainable return to work and job retention, not engagement scores or posture perfection.

Passive and low-friction

No manual calibration, required exercises or high-motivation app. It works in the background.

Objective pacing data

Continuous insight gives a clearer picture than self-report alone.

Inclusive and non-stigmatising

Designed for different bodies, conditions and confidence levels. Private by default, with no "good" or "bad" posture.

Complements clinical care

Fyt supports pacing. It doesn't replace physiotherapy, occupational therapy, medical care or structured rehabilitation.

Fyt is not

  • A treatment, or a clinical rehabilitation programme.
  • A posture-correction or "perfect sitting" product.
  • An exercise or physiotherapy video library.
  • A wellness app with streaks, points or leaderboards.
  • A way for employers to monitor staff.
  • Built for manual or standing work. Fyt is for desk-based and seated roles.
Who it's for

At work, or working from home

A home office with a desk, laptop and an office chair fitted with Fyt

People recovering or struggling at work

Gentle, private support that helps you rebuild sitting tolerance at a sustainable pace, so you can get back to work without overdoing it.

Occupational health and vocational rehabilitation

Objective, continuous data on sitting tolerance and pacing to support a safer graded return to desk work, without adding appointment burden.

Employers

Help people who've been off with MSK or related conditions return and stay in work. Evidence to adjust the job, not just the person: breaks, workstation and how the day is structured.

Insurers and income protection

Support better return-to-work outcomes and reduce repeat absence, with low-friction tools and visible pacing insight during recovery.

NHS and community pathways

Treat work as a health outcome, with trends that inform conversations between appointments.

Government programmes

A practical, inclusive tool that supports work capacity and sustained employment for people with health conditions affecting desk work.

Privacy

Your data belongs to you.

Fear of being monitored stops people saying they're struggling. So Fyt is built around the individual.

Sensor signals are processed on your own computer, and only compact summaries are uploaded. Shared views exist only while your consent is active, are limited to agreed trend summaries, and can be revoked at any time.

If you want to ask for an adjustment, you and your practitioner can choose to write a short note for your manager together. It says what would help, never your data, and only you decide whether to hand it over.

Where we are now

Looking for pilot partners in return-to-work settings.

We're planning an independently evaluated pilot for 2027 with an NHS in-work support service and university partners, subject to funding. It will test whether pacing data helps people sustain their working hours, and publish what does and doesn't work.

Today

Support return to work and sustained employment.

Tomorrow

Support every desk worker who needs better pacing.

Eventually

Every office chair can help people stay well in work.

Partner with us

Help us rebuild how people return to work.

We're looking for occupational health providers, vocational and in-work support services, insurers and employers who want to pilot Fyt, and for partners who want to help build it.
