Our Low Back Stool range merges industrial-grade resilience with space-saving British engineering. Dispatched with Free UK Mainland Delivery, this 685mm Red model is the definitive choice for facilities requiring a bold, high-visibility finish at adult workbench heights.

Indestructible One-Piece Build

  • Structural Unity: Moulded as a single, solid unit of high-impact polypropylene, this stool contains no mechanical fixings, ensuring it remains silent and stable for decades of intensive use.
  • Advanced Hygiene: The jointless construction and non-porous material withstand chemical spills and allow for total sanitisation, making it perfect for science, research, and clinical suites.
  • High-Density Storage: Features an innovative nesting design that allows up to 16 stools to be stacked safely in a vertical column just 2 metres high, clearing floor space instantly.

Safety & Posture Focused

  • Anti-Tilt Engineering: Sleek skid rails widen the base of support to prevent users from rocking back or tipping—a vital safety feature for seating at elevated bench heights.
  • Circulation Support: A built-in 40mm footrest and waterfall front seat edge work in tandem to improve blood flow and reduce leg fatigue during long technical practicals.
  • Severe Use Certified: Independently verified to BS EN16139 Level 2, this stool is rated for "severe contract" use, meeting the highest institutional strength standards.

FAQs: Professional Laboratory Stools

Q: When is the 685mm height the best choice for our studio?

A: The 685mm seat height is specifically dimensioned for workstations that are approximately 900mm to 1000mm high. This is the industry standard for university laboratories, clinical studios, and professional workshop environments.

Q: How does the anti-tilt frame safeguard adult learners?

A: The skid-rail base increases the stool's contact area with the floor. Unlike four-legged stools, this architecture makes it very difficult to rock backwards, maintaining a safer and more stable environment at height.

Q: Will the red finish fade or stain in a lab environment?

A: No. High-impact polypropylene is through-coloured and naturally resistant to the majority of chemicals, acids, and alkalis. The vibrant red finish is UV-stable and can be wiped clean effortlessly.

Q: How stable is a stack of 16 stools?

A: The precision nesting design ensures that each stool locks into the one below it. This creates a highly stable vertical column that won't lean or tip even at its maximum 16-high capacity.

Q: Does the stool require any mechanical maintenance?

A: No. Every stool is delivered fully moulded and ready for use. This jointless design eliminates the need to check or tighten screws over time, reducing long-term maintenance costs for your facility.

Q: Why choose the low-back model over the high-back version?

A: The low-back model is specifically designed for space-efficiency. It provides enough support to keep the spine correctly aligned while remaining compact enough to slide fully under work benches when not in use.

Q: Are these stools environmentally sustainable?

A: Yes. They are 100% responsibly recyclable at the end of their life. Furthermore, their UK manufacture means they carry a significantly smaller carbon footprint compared to furniture imported from overseas.

Q: Why should we purchase our lab seating from Cobolt?

A: With over 50 years of heritage, we are a trusted partner to UK education. We offer Free UK Mainland Delivery and products that are proven to survive the demands of professional academic life.
