The development of the RAY chair was based on a Ph.d thesis about ergonomic school furniture made by Simon Dennehy from the National College of Art & Design in Dublin.

The range of innovative school furniture shall contribute to a more dynamic learning process in primary schools and support active learning. We need to minimize the static and seated learning and provide space for physical activity.

The RAY chair focuses primarily on the seat pan design. Research has shown that traditional ‘right-angle’ sitting encourages poor back alignment, atrophy of the core muscle group and many long term, ‘lifestyle’ illnesses. The most effective way to sit for students is with an open angle between thighs and torso and with hip abduction. This allows the users’ pelvis to rotate forward, until the spine is neutrally balanced and able to support the upper body.

In close collaboration with Irish schools, prototypes of the new school furniture were tested over a long period of time and video recorded for hundreds of hours. Prior to this research, various complex physical tests were performed at the Cork Institute of Technology as comparative tests with standard school furniture. These tests are some of the most comprehensive studies of sitting postures and their consequences.

The choice of materials points to the future and the seat is made of a new and special plastic material that can withstand many deflections. The result is a very comfortable, lightweight chair that is robust for use in schools.

“Creativity is the variety of impressions, which are combined with memories and associations, and filtered through the individual view,” says designer Hans Thyge Raunkjær (* 1957). After training at the Danish Design School in Copenhagen, he worked as a stage designer of a theatre group. He then lived for seven years in Milan, where he also worked as a freelancer for the George Sowden studios. In 1991 he founded his own design studio.

Hans Thyge & Co. works with furniture-, concept- and product design. In addition, the company has a division dealing with 3D graphics, interior design, exhibition design and communications design.

For Labofa Hans Thyge designed the REEF Collection as well as the SHARK and GROOVY programmes – and in cooperation with Hans Sandgren Jakobsen – the COBRA products.
