Teleworking and lower back pain: how your chair is destroying your back (and how to fix it)

Télétravail et douleurs lombaires : comment votre siège détruit votre dos (et comment y remédier)

Introduction

In Switzerland, more than one in two workers telecommutes at least one day a week. And with it has settled a silent epidemic: chronic lower back pain.

Not because working from home is more intense — but because the chairs we work on at home are not designed for 6 to 8-hour sessions. The dining room chair, the sofa, even the 200 CHF office chair from the supermarket: none of these solutions offer the lumbar support the body needs to maintain correct posture for extended periods.

The result? Pain that millions of people accept as inevitable — when it is not.

 

What Sitting Actually Does to Your Back

Sitting is not a natural position for the human body. It places significant stress on the spine — particularly in the lumbar region (the last five vertebrae, L1 to L5).

Disc Pressure

When standing, the pressure on the lumbar intervertebral discs is approximately 100%. When sitting unsupported, it rises to 140-150%. Maintained for hours, this pressure compresses the discs, reduces their hydration, and promotes their progressive degeneration.

Pelvic Tilt

Sitting on a standard chair, the pelvis tends to tilt backward (retroversion). This tilt flattens the natural curve of the lumbar region (lordosis), places the vertebrae in a suboptimal alignment, and keeps the paravertebral muscles under constant tension.

The Chain of Tension

Lower back pain is rarely isolated. A poorly positioned pelvis leads to cervical compensation; the head projects forward to keep the eyes level with the screen, creating cervical tension and headaches. Then the shoulders tense up, and the wrists get tired. It's a cascading postural chain.

 

The 5 Signs Your Workstation Is Harming You

1. Lower back pain at the end of the day: gradually appearing throughout the workday
2. Neck pain and headaches: particularly in the early afternoon
3. Numbness in legs or buttocks: nerve compression due to poor seating
4. Shoulder tension: consequence of compensatory cervical posture
5. Abnormal fatigue at the end of the day: the body expends energy to maintain posture

 

The 30-Second Test to Assess Your Posture

How to do the test:

Sit at your usual workstation and observe your natural position, without intentionally straightening up.

Check the following points:
- Are your knees at the same height as your hips or slightly below?
- Is your back in contact with the backrest of your chair?
- Do your feet rest entirely flat on the floor?
- Is your screen at eye level without you having to lower or raise your head?
- Are your shoulders low and relaxed?

If you answered "no" to two or more of these points, your sitting posture is likely generating muscular tension that accumulates daily.

 

Why Most Home Office Chairs Are Unsuitable

A professional ergonomic office chair, the type used in large companies, costs between 800 and 2,000 CHF. It is adjustable in height, seat depth, lumbar support, armrest height, and backrest tilt. It has been designed by ergonomists to maintain the body in correct alignment for long hours.

The average home chair has none of this. Its seat is flat (it doesn't slightly tilt the pelvis forward), its backrest has no integrated lumbar support, and its height is rarely adapted to the user's body shape.

Changing chairs is the ideal solution, but it is expensive and impractical for the majority of teleworkers.

 

The Accessible Solution: The Ergonomic Cushion

A quality ergonomic cushion can transform any chair into an ergonomically correct seat, for a fraction of the price of a professional chair.

It addresses two critical points of sitting posture:

1. The coccyx/hip seating: a memory foam cushion with a coccyx cut-out restores the natural tilt of the pelvis, allowing the lumbar lordosis to be maintained without muscular effort. The coccyx cut-out also relieves pressure on the tailbone, particularly important for people with injuries or suffering from coccydynia.

2. Lumbar support: a lumbar cushion placed between the lower back and the chair's backrest maintains the natural curve of the lumbar region. It compensates for the lack of integrated lumbar support in the chair and significantly reduces disc pressure.

 

The Sōmna Seat Cushion Set: Two Cushions, One Corrected Posture

This is a two-piece set designed to correct the two critical points of sitting posture in a single solution.

The seat cushion (41×31×8 cm) in memory foam with a coccyx cut-out naturally repositions the pelvis in slight anteversion, restoring lumbar lordosis without conscious effort. Its breathable scuba knit fabric cover prevents heat and discomfort during long sessions.

The lumbar cushion (40×40×7 cm), placed against the chair's backrest at lumbar height, maintains the natural curve of the lower back and reduces tension in the paravertebral muscles.

The two cushions work together but are also effective separately depending on your needs. Their covers are removable and machine washable.

 

Beyond the Cushion: Other Essential Adjustments

A good cushion solves seating-related problems. But optimal posture also requires a few additional adjustments:

Screen height: the top of the screen should be at eye level. If your screen is too low, you lean forward, creating cascading cervical tension. A simple screen stand costing a few francs can solve this problem.

Distance to the screen: your screen should be about 60-70 cm from your eyes. Too close, you strain your neck forward.

Active breaks: even with the best cushion, prolonged sitting generates tension. A 5-minute break every 60-90 minutes: standing, walking, or stretching, significantly reduces the accumulation of muscle fatigue.

Foot placement: your feet should rest entirely flat on the floor. If your chair is too high, a simple footrest (or even a ream of paper) can correct this immediately.

 

Expected Results

People who adopt a quality ergonomic cushion generally report:

- A reduction in lower back pain at the end of the day from the first week
- A decrease in cervical tension after 10 to 15 days
- Improved concentration and energy in the afternoon; postural fatigue consumes cognitive energy
- Better sleep quality; muscle tension accumulated during the day disturbs nighttime sleep

 

Conclusion

Lower back pain related to telework is not inevitable. It is a direct consequence of a mismatch between the human body and the surfaces we spend our days on. And this mismatch can be corrected simply, quickly, and without significant expense.

A well-chosen ergonomic cushion is one of the most cost-effective investments for your daily well-being: a few francs that transform your posture, relieve your pain, and indirectly improve the quality of your sleep.

At Sōmna, we have selected the Sōmna Seat Cushion Set precisely for this reason. Because well-being doesn't stop when you go to bed; it begins with the position you maintain throughout your day.
