Buro Quantum, mesh back with arms

One Chair, Two Backs

The Quantum is Buro's adjustable task chair for busy workplaces and home offices. A synchronised seat and back tilt, a ratchet height-adjustable back, adjustable lumbar support and a depth-adjustable seat slide let each user set their own position, and the polyurethane moulded seat has a memory-foam layer to cushion long sittings.

Choose a breathable black mesh back, the same mesh back with Buro's height-adjustable headrest, or a black upholstered back. Buro states the Quantum is endorsed by the Australian Physiotherapy Association, meets ANSI/BIFMA x5.1-2017 and holds GREENGUARD Gold certification.

The Details

The tilt, the adjustable back, the seat, the headrest option and the certifications.

Back and Lumbar You Can Set

The back height adjusts on a ratchet and the lumbar support is adjustable, so the curve sits where your lower back is.

A polyurethane moulded seat with a memory-foam layer, 530 mm wide, in black fabric.

Back, Headrest and Arms

This Listing

This listing brings together Buro's two Quantum models. Choose the back: Mesh (Buro codes 169-M3, or 169A-M3 with arms), Mesh with headrest (the same chair supplied with Buro's 169-HDREST height-adjustable headrest), or Upholstered (169-63, or 169A-63 with arms). Then choose with or without arms; Buro describes the arms as height, width and depth adjustable. All versions are black, on a black nylon base.

Comparing? The Buro Axon ergonomic office chair swaps the adjustable back for a flex-back that moves with you, and the Buro Mentor mesh office chair is Buro's mesh chair available with a nylon or polished aluminium base.

Why We Chose Buro

Buro Seating was founded in Auckland in 1994 and has been part of ACCO Brands since 1 March 2025. It publishes a specification sheet, line drawings and certification details for its chairs, so the figures on this page are Buro's own rather than ours.

Chair Dinkum is an authorised Buro dealer. You can sit in Buro chairs at our Sydney showroom (Shop 1, 209 Harris Street, Pyrmont NSW 2009, by appointment, Mon–Fri 9am–5pm), and we quote whole floors through our commercial fit-out team on 02 9640 0642.

All figures are Buro Seating's, from the Quantum Mesh Back and Upholstered Back product pages and specification sheets. Buro's page lists a 140 kg weight rating; its specification sheet states AFRDI 142 approval for users up to and including 135 kg in single-shift use, so we quote 135 kg as the certified figure. Guarantee terms are on Buro's guarantee page and our warranty page.

Frequently Asked Questions

Buro's specification sheet states the Quantum is AFRDI 142 approved for users up to and including 135 kg in single-shift use. Buro's product page also shows a 140 kg weight rating, which is Buro's own figure rather than the certified load. Read how office chair weight ratings work in Australia for what the ratings mean.

No. Buro offers the height-adjustable headrest (169-HDREST) for the mesh back only, so it appears here as the Mesh with headrest option.

Mesh breathes and suits warm rooms and long days; the upholstered back is softer and more traditional in look. Mechanism, seat, arms and adjustments are the same on both.

The Quantum's back adjusts for height and its lumbar is adjustable. The Buro Axon has a fixed-height flex-back that moves with you and fixed lumbar support. Both have a synchro tilt, a seat slide and a memory-foam seat. The Buro Force mesh office chair is another option with height-adjustable lumbar.

Yes. Book a time at our Sydney showroom in Pyrmont (Mon–Fri 9am–5pm, by appointment) or call 02 9640 0642.
