THONET cantilever chair with armrests • S 55 Evo range
A comfortable, elegant all-rounder based on the construction principle of the cantilever chair. With its continuous seat shell, it offers the highest comfort, is formally clear in design and made in the finest Thonet quality. Its range of use extends from conference and meeting rooms, through training and seminar rooms, to the living area. The model is made in two different backrest heights, as a swivel chair variant and also in a stackable version.
The S 55 PF Evo cantilever chair is the fully upholstered Evo version of the range: its shell made of moulded plywood has a lumbar support and is upholstered all around, either with a simple seam or a French seam. The frame is made of chrome-plated tubular steel, the armrests of elastomer plastic, optionally with nappa leather for an additional charge. It is 88 cm high, the seat height is 47 cm and the armrest height is 67 cm. POM plastic glides and felt glides are available for an additional charge.

Full upholstery: With full upholstery, the seat shell is covered all around with fabric or leather, including the back. The wood surface is then no longer visible. This makes the chair appear softer, calmer and more homely than in the mirror-upholstered version.
Lumbar support: The lumbar support is a targeted shaping of the backrest at the level of the lumbar vertebrae. It supports the lower back exactly where it has its natural curve, relieving it during longer periods of sitting – without the need for additional mechanisms or adjustments.
Elastomer plastic: Elastomers are plastics that retain their shape but yield slightly under pressure. Thonet uses them for the armrests: they feel pleasantly warm to the touch – unlike bare metal – give a little when leaned on, and are highly resistant to daily use.
