The new mechanism allows the user to change the height of the chair by up to 11,5 cm/4,5 inches by making use of a lever under the seat. This allows the chair to be optimized both for different people in the household and to the nature of the task in hand. With desk-bound work often entailing up to eight hours of sitting a day, the combination of flexible movement and adjustable height allows for optimal posture and maximum comfort, minimizing lumbar stress and helping to improve focus.

The seats of the height-adjustable Beetle and Bat Chairs are set onto a black four-star swivel base in steel and aluminum – an elegant contrast to the five-star base common to commercial furniture. The base is available with either fixed gliders or castors, depending on whether the chair is to be used in one place, or wheeled around the home as required.
