Elegant white or black acrylic shells cradle the most stylish of executive chairs – the Xenon. The shell swoops down from the generously proportioned backrest to integral slim, shaped, arms which fold around to the underside of the seat shell. A high quality knee tilt ensures maximum comfort and avoids discomfort through upper leg blood vessel constriction. High density moulded foams and an integral contoured lumbar support add to the easy-seating package. A brushed aluminium five star base continues the focus onsophisticated styling at ground level. In chemistry Xenon is a member of the noble gas family – in seating it is a member of the style and comfort family.Product Features:• Quality knee tilt mechanism with tilt tension • High density moulded foam seat and backrest • One piece seat, backrest and arms • Integral contoured lumbar support • Nylon fixed armrests • Brushed aluminium 5 star base
