Product Overview: Blush Pink Postura+ Chair (430mm, Ages 11–14)

The Blush Pink Postura+ 430mm chair combines a calming, modern aesthetic with the rugged durability required for high-traffic environments. Perfectly sized for pupils aged 11–14, it offers a welcoming alternative to standard colours, enhancing engagement in secondary classrooms, breakout zones, and community spaces.

Ergonomic Design for Growing Students

  • 430mm seat height matched to DfE size mark 5 for ages 11–14
  • Curved backrest promotes healthy, upright posture during lessons
  • Soft waterfall seat edge improves circulation and reduces fidgeting

Built for High-Demand Environments

  • One-piece polypropylene mould eliminates loose screws or joints
  • Gas-injected legs provide superior strength and anti-rock stability
  • Tested to a 204kg load rating for dependable long-term performance

Calming, Contemporary Blush Pink Finish

The Blush Pink colourway offers a softer, more sophisticated look than traditional primary colours. It is particularly effective in creating calm breakout areas, modern libraries, or welcoming waiting rooms where reducing visual stress is a priority.
