ErgonomicsPeople are different; they have different bodies, different needs and different uses. Whatever type of person you are, we are sure that you will find your perfect chair partner in this collection. Like people, chairs are different too; shape, movement, style, colour, and size all contribute to whether or not a chair will suit an individual. If you think about who you are and what you do, selecting a chair can be easy.The BodyEvery body is different and in Australasia that is especially true. Biologists who study human measurements (anthropometrics) tell us that our diverse ethnic backgrounds combined with a rich lifestyle have led to one of the world's largest variances in body size, shape, weight and proportion. It is this anthropometric data which is the starting point for designing a great range of seating. It tells us that no matter how adjustable an office chair is, there is no such thing asa "one size fi ts all"" solution. In addition to differences in body shapes, studies in biomechanics(how we move) and ergonomics (how we work) show that we have different needs in terms of movement at work. Welcome to the science of great ergonomic seating design. In this collection of fine seating we have greatly enhanced the concept of families of chairs, allowing you to select one range to fit out your entire office with a consistent, coordinated or professional image.
