The GREENGUARD Certification Program (formerly known as GREENGUARD Indoor Air Quality Certification) gives assurance that products designed for use in indoor spaces meet strict chemical emissions limits, which contribute to the creation of healthier interiors. Achieving GREENGUARD Certification gives credence to manufacturers’ sustainability claims, backing them with empirical scientific data from an unbiased, third-party organization.

GREENGUARD Gold Certification (formerly known as GREENGUARD Children & Schools Certification) offers stricter certification criteria, considers safety factors to account for sensitive individuals (such as children and the elderly), and ensures that a product is acceptable for use in environments such as schools and healthcare facilities. It is referenced by both The Collaborative for High Performance Schools (CHPS) and the Leadership in Energy and Environmental Design (LEED) Building Rating System.

The workplace has evolved and so did our work tools: D Chair is a highly individualized performance task chair that is both comfortable and versatile. Contemporary and minimalistic, it is a proven choice for all work areas; from executive offices to home-offices and front desks.

  • Adjustable backrest tilt, seat depth and armrests (with Pro-Support® and Dyna-Support®).
  • Optional high or low backrest and lumbar support (with Pro-Support®).
  • High or low backrest with fine mesh; wide color and material (fabric, leather or eco-leather) options.
  • Complies with international workplace health and safety standards.


Backrest Tilt

Researches have concluded that chair design has the greatest effect on the pressure distribution on our bodies while seated. We design for dynamic sitting and the right posture before all. A balanced, stress-free sitting and correct weight distribution leads to a healthy posture and improved circulation. 



Seat Slide

By fine tuning the seat depth, a more natural and supportive sitting experience becomes achievable. Adjustable seat slide mechanism allows easy back and forward adjustment of the seat pan. It also helps users with different upper leg lengths to effectively find their most comfortable seated position. 


Lumbar Support

D Chair’s lumbar support is adjusted according to different body sizes, helping the user to gain correct sitting habits.

Armrest Width

Minimize articular disturbances caused by long hours of work. Reduce accumulating fatigue in the shoulders and the neck by customizing the armrest width to your body and your task.



Armrest Height

Easily and individually adjust each armrests’ height to minimize the risk of discomfort. Ideally, the work surface should be at level with or a rest a little lower than your elbow. Adjusting armrests to your task in this way helps reduce the recurrence of repetitive strain injuries like tennis elbow or CTS (carpal tunnel syndrome).
