Product Overview: Jet Black Postura+ Chair (460mm, Ages 14+)

The Jet Black Postura+ (460mm) is the mature choice for adult learning environments. Tailored for the adult physique (14+), it signifies a step up from lower school education, offering a sleek, neutral aesthetic that fits perfectly in higher education hubs, performance arts spaces, and professional meeting rooms.

Ergonomics for Adult Users

  • 460mm seat height fits standard adult desks and conference tables (710-760mm)
  • Sculpted lumbar curvature promotes an upright, professional posture
  • Waterfall seat edge ensures circulation is maintained during long lectures or exams

Certified for Severe Use

  • Achieves BS EN 16139 Level 2 – independently tested to withstand severe use in public venues
  • Gas-injected legs ensure rigid stability for user weights up to 204kg
  • Single-piece construction eliminates the squeaks and maintenance of metal-framed chairs

Performance & Practicality

Black is essential for drama studios as it does not reflect stage lighting. In general use, it is the ultimate low-maintenance finish, hiding scuffs, ink, and daily wear better than any other colour.
