Trade terms for professionals and design studios
Every corner office has two spokespeople: the person and the chair. Visitors read the second one first. Jera Chair by Las Mobili, designed by Orlandini Design, is written for that reading — a modern executive chair, comfortable and enveloping, its clear, decisive shapes enhanced, in the manufacturer's words, by smooth upholstery or sewn bands. The quilted version layers a padded resin pad with 150 g/m² velvet backing under the cover and finishes it with hand-crafted, tone-on-tone stitching — tailoring you can sit in.
The range is a hierarchy in two back heights: high for the presidential desk — the Jera desk it was drawn to sit behind — with an optional headrest, low for meeting tables. Both share one enveloping monocoque — internal metal structure, cold-foamed flexible polyurethane at 70 ±5 kg/m³, CFC- and HCFC-free, flame-retardant Class 1 per manufacturer data — on a polished die-cast aluminum five-star base Ø 670 mm with self-braking Ø 50 mm twin-tread casters. Two mechanisms decide how it moves: GOL, free-floating tilt with gas lift and 360° swivel, or GOA, lockable in 4 positions with crank-adjusted tension and anti-shock release. Gas columns conform to DIN 4550 above level 4 — manufacturer data.
The family beyond the desk
Jera furnishes the whole executive floor: visitor chairs carry the same low-back shell on a die-cast pyramid base (520 x 520 mm, 360° swivel plate) or a chromed Ø 11 mm steel sled; the tub version serves the boardroom with a laterally hinged seat that tips up 93° for row stacking and an optional right-hand writing tablet with anti-panic joint. Upholstery comes from the LAS colour folder: eleven options across fabrics, Ecopelle and leather. Product certificates can be downloaded on this page.

Think of the three heights as registers. High back reads presidential and ships with the padded seat cushion as standard; medium back is the everyday leadership chair — same cushion, plus it is the only one that accepts the optional upholstered headrest; low back works meeting tables, where the person should be taller than the chair. One monocoque language across all three lets a floor state hierarchy without mixing furniture families.
GOL is the no-settings chair: free-floating tilt with no intermediate or final locks, gas height adjustment, 360° swivel — you sit, it follows. GOA is for people who tune their seat: tilt lockable in 4 positions, tension set by crank, lock and release by lever with anti-shock system. Both use gas columns that conform to DIN 4550 above level 4, per manufacturer data.
A metal structure inside cold-foamed flexible polyurethane at 70 ±5 kg/m³ — CFC- and HCFC-free, flame-retardant Class 1, manufacturer data — plus a 35 mm seat cushion at 55 kg/m³. The quilted version interposes a padded resin layer with 150 g/m² velvet backing and finishes with hand-crafted tone-on-tone stitching. The enveloping softness has an engineered skeleton.
Yes — that is Jera's brief. Visitor chairs put the same low-back shell on a pyramid die-cast base with 360° swivel plate or on a chromed steel sled; the tub version lines the council room, its seat tipping up 93° on lateral hinges so rows can be stacked, with an optional anti-panic writing tablet for note-taking. The hierarchy is told by back heights, not by different chairs.
Fourteen coverings from the LAS colour folder — Poli, Ecopelle, Crepe, Stretch, Melange, Trevi, Lana, the Gabriel and Flukso fabric families, leather — plus customer's own material for projects with their own textile identity. Decide smooth versus quilted, then match casters to floors: hard on carpet, soft on stone or tile. Physical samples are available and their cost is fully credited at order confirmation.
For facility managers and designers: five Jera Chair decisions from the corner office to the boardroom.
High back for the presidential office, medium for everyday leadership — and the headrest option — low for meeting tables. The monocoque stays the same; the height does the talking.
GOL free tilt for the no-settings executive; GOA with 4 locking positions, crank tension and anti-shock lever for those who tune their chair. Gas columns conform to DIN 4550 above level 4 — manufacturer data.
Pyramid-base or sled visitor chairs in front of the desk; the tub version in the boardroom, with its 93° tip-up seat for row stacking and the optional anti-panic writing tablet for sessions that need notes.
Smooth or quilted — the quilted with velvet-backed padding and tone-on-tone stitching — across fourteen coverings including leather and customer's own fabric. Then pick casters by floor: hard on carpet, soft on hard surfaces.
Approve physical samples under your own lighting — their cost is fully credited at order confirmation — then lock back heights, mechanisms, coverings and caster types in writing before production.
