The VOILA chair comes with a three dimensional knit back that distributes weight evenly in all directions. This allows the knit back to self-adjust and take the shape of the users. The VOILÀ seat is available in a variety of regular and recycled fabrics, PVC free synthetic leather or in leather. The back is offered in 8 knit colors. The VOILÀ is offered with a fixed or adjustable back, 3 seat sizes, 4 cylinder heights and many types of mechanisms, from the simple swivel to the multi-function, with or w/o a seat slider. Optional lumbar and visco-elastic foam on the seat add to the comfort of the chair. Many models of fixed or adjustable arms (height/width, pivoting, retractable) are available, as well as a choice of resin or aluminum bases and various casters. All models are available in black or polished aluminum finish.
