Before anyone sits down, the arms have already done their work. On Not Guilty they are rounded and turn slightly outwards, so the seat appears to open towards whoever comes round the desk; Quinti, based at Cesa near Arezzo, says simply that they invite you to sit. Cristian Gori drew them into the body instead of fixing them on: across all five versions the armrests are integrated, never an extra to be ordered separately.

Of all our executive office chairs, this is one where the tall model and its smaller companions share a single drawing. The tall one, QX222700S, stands 120/128 cm (47.2/50.4 in), lets the seat travel between 46 and 54 cm (18.1 and 21.3 in) and covers 72 × 72 cm (28.3 × 28.3 in) of floor. It turns on a Skill five-star base in polished aluminium, Ø 70 cm (27.6 inches), on castors, and arrives with the M5 tilt mechanism as standard; an M3 or M4 can replace it. Inside, a load-bearing rigid polyurethane frame is coupled with cold-cured foam, which Quinti says keeps disposal after use quick and low in impact.

Height sorts the four armchairs. Two can be raised: the Skill version, on four aluminium spokes with glides, and the Leggera, on a four-spoke polished star 680 mm (26.8 in) wide with glides (4P) or castors (4R), each 80/88 cm (31.5/34.6 in) tall and swivelling. Two keep a set height of 80 cm (31.5 inches): one swivels on four spokes of painted wood in walnut, natural, moka or open-pore black, the other stands on four tapered legs, black V6 or a Quinti colour from four pieces. We place them opposite the desk for visitors and along the table of an executive office suite. La Mercanti places the high back beside one armchair, for the client to compare the pair ahead of the order.

FAQ

From floor to top, how tall does the high-back model stand?

Between 120 and 128 cm (47.2 and 50.4 in), according to the seat setting. Only the QX222700S has a high back; the four armchairs in the series are considerably lower. The figure is printed in Quinti’s price list for 2026.

What kind of support carries the Not Guilty desk chair?

A Skill five-star base in polished aluminium, 70 cm (27.6 in) across, running on castors. Quinti fits that five-star version to the high-back model only, and it comes as standard with the QX222700S code.

Which wood finishes can be ordered for the swivel version?

Four, all painted: walnut (NC), natural (RN), moka (RT) and black with an open-pore finish (NP). They apply to the QX223V00S, the Not Guilty armchair that turns on a four-spoke wooden base.

Can Not Guilty be ordered in a faux leather finish?

Yes: Ecopelle Soul, listed in category 3 of the Quinti covering card. Its surface is 100% polyurethane, and Quinti declares more than 100,000 cycles in the EN ISO 5470-2 test for this material.

At the end of its working life, what happens to a Not Guilty chair?

It comes apart. Quinti designed the series to be disassembled when its life is over, so that parts and components can be reused, recycled or recovered instead of being discarded together.

Furnishing a private office around Not Guilty

The tall chair on the desk side, the lower chairs facing it, shared bases and one cover category: five steps built on figures from Quinti’s 2026 list.

Not Guilty on the desk side

On the desk side goes the QX222700S, on its Skill five-star base with castors. It takes 72 × 72 cm (28.3 × 28.3 in) of floor, with a seat 50 cm (19.7 in) wide and 45 cm (17.7 in) deep.

Lower chairs across from it

Facing it go the armchairs: 80/88 cm (31.5/34.6 in) for the swivel versions with height adjustment, on Skill or Leggera bases, and 80 cm (31.5 in) for the wooden base and the tapered legs. Each weighs 15 kg (33.1 lb).

Glides or castors on the Leggera

The QX223R00S comes with glides (4P) or castors (4R) under a four-spoke polished base 680 mm (26.8 in) across. Both swivel and adjust, with the seat between 50 and 62 cm (19.7 and 24.4 in).

Tapered legs in black or colour

The QX223100S stands on four tapered legs: a frame painted black (V6), or one of the Quinti colours (VQ) with a minimum order of four pieces. Height 80 cm (31.5 in), seat at 45 cm (17.7 in).

One cover category for all

The tall chair and the armchairs are ordered from the same price-list categories, 2, 3, 5, 7, 8 and IM, so they can share one fabric or one leather. Crepè, Laser, Chili, Melange, category 6 leather and Horo are not available.
