RYTHMES & SONS SOPHIA^®, High & adjustable Orchestra Chair with round seat

Ideal chair for percussionist / stage manager / technician

It is equipped with a synchronous mechanism offering a coordinated and simultaneous adjustment of the inclination of the seat and backrest to obtain an optimized angle of comfort.

The adjustment is made using 2 levers located on one and the same side (right side) to facilitate changes. This system offers daily comfort in the use of the chair. The levers are easily located. The user can trigger the mechanisms with just one hand without having to put down his instrument.

The height adjustment is carried out by means of a hydropneumatic cylinder.

The height and inclination adjustable footrest allows the user to find balance as well as a suitable posture when sitting-standing, or even sitting.

This chair is guaranteed without squeaks and extraneous noise thanks to a good quality in the conception and in the making.
The manufacturing quality guarantees a 10 years lifetime minimum.
