DuoBack Xenium Basic Chair

The DuoBack Xenium Basic chair delivers advanced ergonomic support for modern workspaces. Its standout feature is the unique split backrest, which moves independently on each side. This design relieves pressure on the spine by up to 50%, making it ideal for users with back pain or spinal conditions. Each backrest pad adjusts separately, ensuring the chair hugs your back and supports your natural posture.

Transitioning between tasks feels effortless, thanks to the multi-lock synchronous mechanism. This feature allows the seat and backrest to move together, promoting dynamic sitting and reducing fatigue. You can tailor the seat depth to your leg length, ensuring proper circulation and comfort throughout the day. The gas-assisted seat height adjustment lets you find your optimal sitting position quickly.

Armrest options include 2D and 3D adjustments for height, width, and depth. This flexibility supports your arms during typing or meetings, reducing shoulder strain. The chair’s height-adjustable backrest ensures the lumbar support aligns perfectly with your lower back. For extra comfort, you can choose memory foam or a coccyx relief zone in the seat cushion.

The Xenium Basic accommodates users from 5’4″ to 6’4″ and supports weights up to 110 kg. Its robust five-star base and smooth-rolling castors ensure stability and easy movement on any floor type. The chair comes in stylish black or grey finishes, blending seamlessly into any office or home environment.

Ergonomics Live: How a Floor Walk Delivered Immediate Impact

The Challenge

A technical team operates in a highly controlled indoor environment, undertaking a combination of intensive screen work and physical tasks involving delicate materials.

Despite having adjustable desks, ergonomic seating, regular DSE assessments and manual handling training, management wanted an independent review to ensure that workstation setups and working habits had not drifted over time.

Our Approach

Osmond Ergonomics & Wellbeing delivered a half-day Ergonomics in Practice Floor Walk, combining:

  • A practical workshop on posture, fatigue and workstation setup
  • One-to-one workstation reviews carried out in the live working environment

Advice was tailored to the team’s specialist equipment, space limitations and physical demands.

The Impact

Out of 14 staff, approximately 50% of workstations were adjusted on the day.

These small but critical changes, including chair height, screen position, and input device placement, immediately reduced strain and improved comfort. The session also refreshed awareness of good working habits, helping prevent the slow return of poor posture that leads to musculoskeletal issues.

Client Feedback

“The session was perfectly pitched for the team. The preparation beforehand made it highly relevant, which is why the team were so engaged.”

Why This Matters

Even in well-managed workplaces, ergonomic drift is common. A simple floor walk delivers quick, measurable improvements that protect wellbeing, reduce injury risk, and boost productivity.

As many services move towards virtual delivery for speed and convenience, this case also highlights the enduring value of being physically present in the working environment. Observing people at work and providing live, individualised feedback allows for nuanced, practical adjustments that simply cannot be replicated remotely.

That’s what makes our floor walking service so valuable and impactful for both individuals and organisations.
