Trade terms for professionals and design studios
Before the meeting starts, the room has already spoken — and the loudest object in it is the chair behind the desk. Jera Chair by Las Mobili, designed by Orlandini Design, gives that object the right vocabulary: a modern executive chair, comfortable and enveloping, with clear, decisive shapes enhanced — as the manufacturer puts it — by smooth upholstery or sewn bands. The quilted version adds a padded resin layer with 150 g/m² velvet backing and hand-crafted tone-on-tone stitching: the tailored register, built into the seat.
Three back heights write the hierarchy: high for the presidential cabin, medium for everyday leadership — the only version accepting the optional headrest — low for meeting tables. One enveloping monocoque underlies all three: internal metal structure in cold-foamed flexible polyurethane at 70 ±5 kg/m³, CFC- and HCFC-free, flame-retardant Class 1 (manufacturer data), on a polished die-cast aluminium five-star base Ø 670 mm with self-braking Ø 50 mm twin-tread castors. Movement is a choice of two mechanisms: GOL free-floating tilt with gas lift and 360° swivel, or GOA lockable in 4 positions with crank tension and anti-shock lever. Gas columns conform to DIN 4550 above level 4 — manufacturer data.
From the cabin to the boardroom
The family continues past the desk: visitor versions place 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, and the tub version equips the council room with a laterally hinged seat tipping up 93° for row stacking, plus an optional right-hand writing tablet with anti-panic joint. Upholstery spans fourteen options from the LAS colour folder — fabrics, Ecopelle, leather, and customer's own fabric. Product certificates can be downloaded on this page.

High back is the presidential register, with the padded seat cushion as standard; medium back serves everyday leadership — same cushion, and it is the only version that accepts the optional upholstered headrest; low back belongs at meeting tables, where the person should read taller than the chair. One monocoque family, three registers: the hierarchy is stated without changing design language.
GOL for executives who want zero settings: free-floating tilt without locks, gas height, 360° swivel. GOA for those who tune the chair: 4 locking positions, crank-adjusted tension, anti-shock lock/release lever. Both run on gas columns conforming to DIN 4550 above level 4, as declared by the manufacturer — specify per person, not per floor.

For admin heads and architects: five Jera Chair decisions from the corner cabin to the council room.

Pyramid or sled visitor chairs before the desk; tub chairs in the council room with 93° tip-up seats for row stacking and optional anti-panic writing tablets.
Fourteen coverings including leather and customer's own fabric; the quilted version adds velvet-backed padding with tone-on-tone stitching. Match castors to floors: hard on carpet, soft on hard surfaces.
