Peter Opsvik

The balans® concept

At the very beginning of 1976 Hans Christian Mengshoel (1946) initiated a study that set out to answer how we could sit in more balanced and ergonomic ways. Through observation and research, Mengshoel found that a seat which was tilted slightly forward, encouraged a natural posture which provided greater mobility and relieved unwanted pressure while seated. The idea of shin support was introduced to keep the user from sliding off the seat while simultaneously maintaining an open hip angle. With this, Mengshoel initiated the concept of the kneeling posture in Norway and set the mark for a truly experimental time in Norwegian design history. Shortly after Peter Opsvik designed and devloped what was to become the first widely used and sold kneeling chair, the Varier Variable.

Peter Opsvik

One of the most common constraints on product development is that people think too conventionally.
When we dream, these kinds of checks are switched off, and thoughts, ideas and experiences mingle freely without being overridden by restrictions or conventions.
Often when I wake up early in the morning, I find that I can tap this creative capacity that is released during dreaming. I lie in bed; half awake, and think through the difficulties that need to be resolved in the course of the day. Often, I go back to sleep and let my dreams work on this reality.
The result can be a burst of creativity that often results in imaginative and unexpected connections between stored experiences. Indeed, very often the idea for new solutions is born from this seemingly unstructured dream impulse.

Varier Gravity

This is the ultimate ergonomic chair for relaxation. It is extremely comfortable and gives the best possible support when reclining. The Gravity recliner meets almost every seating requirement for exceptional ergonomics without strain.

Leaning forward, the Gravity Balans chair can be used as a kneeling chair. Shift your weight slightly backwards for an upright position, placing your feet on either the floor or shin cushions for variation. To assume a reclined position, gently push away from the ground.

We believe the Thatsit is the ultimate ergonomic kneeling chair because it allows the most movement and offers the greatest support:

  • Adjustable ergonomic backrest depth / angle
  • Great lumbar support
  • Adjustable backrest height
  • Adjustable leg supports to adjust for leg length: (5ft to 6ft4in)
  • Sprung, flexible shin pads to prevent shin pressure and allow extra movement
  • Elbow rests - to support the weight of the arms when sitting against the backrest
  • Suitable for a standard height desk / dining table (71-76cm)
  • 8-10hrs sitting thanks to high quality injection-molded foam + lots of movement + back support for tired moments

The Hag Creed

HAG Creed

There is nothing else quite like it... The HAG Creed is based on two of our most loved originals: the H04 and H05.

These two office chairs were both so wonderful we could never really choose which we liked best. Now we don't have to:
The HAG Creed is a beautiful hybrid of the two.
