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

The Orange Postura+ 430mm chair is designed to make a statement. Combining the proven ergonomic benefits of the Postura+ range with a high-visibility, energetic colourway, it is the ideal furniture choice for stimulating creativity in secondary school art rooms, tech hubs, and busy refectories.

Ergonomics for Active Learners

  • 430mm seat height (DfE Size 6) supports the rapid growth phase of 11–14 year olds
  • Curved lumbar design promotes better posture during focused creative work
  • Waterfall seat edge ensures comfort and circulation during double periods

Durability Meets Design

  • Impact-resistant polypropylene withstands the rigours of daily institutional use
  • Gas-injected legs provide immense strength without the need for metal frames
  • UV stabilised colour ensures the vibrant orange hue resists fading in sunlit rooms

Zoning & Wayfinding

Orange is a powerful tool for zoning. Use it to designate creative wings, signify 'collaboration zones' in libraries, or simply to add warmth and appetite appeal to school canteens and breakout areas.

The Cobolt Promise

  • Free UK Mainland Delivery: We absorb the shipping costs to give you the best possible value per unit
  • Reliable Supply: UK manufacturing ensures consistent stock levels and shorter lead times
  • Project Coordination: Our team manages the logistics, ensuring delivery fits your timetable

Where is this Orange stacking chair used?

The Orange Postura+ is chosen by facility managers who want to break away from clinical greys and blues. It is widely specified for Performing Arts centres, design technology labs, student unions, and modern cafeteria spaces. Its vibrant tone helps stimulate social interaction and creativity, while its rugged build survives the high footfall of these busy areas.

Key Features

  • Ergonomic Size 6 – The 430mm seat height is the BS EN 1729 standard for Key Stage 3 (11-14 years), ensuring compliance.

  • Zero Maintenance – Single-piece moulding means no screws to tighten and no metalwork to rust or chip.
  • UV Stabilised – Essential for bright colours; the UV filter prevents the orange from chalking or fading in direct sunlight.
  • Safety First – The anti-rock design prevents tipping, reducing accidents in active classroom environments.
  • Easy Hygiene – The smooth surface is impervious to stains and easy to wipe down—perfect for dining and art messes.
  • Eco-Conscious – Made in the UK from 30% recycled materials and fully recyclable at end-of-life.
  • Lightweight Strength – At just 3.6kg, it is easy for students to move, yet rated to support 204kg.
