A Sparco race car seat is the model of the R100S office chair. For optimal comfort, the seat of the office chair is wider and lower.
The back may be adjusted for lumbar support and recline. The chair includes a mechanism that prevents the back from reclining farther than 150°, which keeps it from toppling over.
It also includes a polished aluminium base, five robust wheels, a rocking mechanism, and a piston verified by SGS, BIFMAX5.1, and EN1335.
