Buro x PowerA Sentinel in a gaming setup
An Ergonomic Gaming Chair Built Like an Office Chair
The Sentinel is the mesh-backed chair in the Buro x PowerA gaming range. It pairs a breathable, ergonomically shaped mesh back with a height and depth adjustable headrest, body weight activated lumbar support and what Buro calls 5D armrests with soft PU arm pads. Under it sits Buro Dynamic Intelligence™, the mechanism Buro describes as supporting active posture and natural movement, with cable controls for seat height and seat depth.
It is certified to the same office-chair standard as Buro's task chairs (ANSI/BIFMA X5.1-2017), GREENGUARD Gold certified and endorsed by the Australian Physiotherapy Association. If you are after a gaming chair in Australia that will also hold up to a working day at the desk, that is the point of it.

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 and dimensioned line drawings for each chair, and states its certifications, weight rating and guarantee model by model.
We sell the Buro x PowerA chairs because they carry the same paperwork as Buro's office range: ANSI/BIFMA X5.1-2017 certification, GREENGUARD Gold and Australian Physiotherapy Association endorsement.
