Product catalog summary
Introduction to Ergonomics
Humans are not naturally suited for prolonged sitting, which was initially a temporary relief from standing. Klöber focuses on ergonomic seating solutions that prioritize human needs, avoiding standard solutions to alleviate strain during extended sitting periods.
History of Sitting
Sitting evolved from sitting on the ground to using monoxylic chairs and thrones, with significant developments like Goethe's ergonomic insights and Margarete Klöber's 1935 "Polstergleich" spring technology enhancing seating comfort.
The Problem of Sitting
Static sitting is associated with back problems, leading to significant economic costs due to lost working days. The spine's structure supports movement, but static sitting can cause issues like slipped discs, especially in the lumbar region.
Sitting Positions
Dynamic sitting, involving regular posture changes, is recommended for back health. Klöber chairs support dynamic sitting with mechanisms that accommodate various positions, reducing strain on intervertebral discs and enhancing well-being.
What a Swivel Chair Needs
Klöber chairs include synchronized mechanisms that adapt to body movements, providing ergonomic support. Features like adjustable seat depth, lumbar support, and armrests help reduce neck and shoulder strain. The Point-Synchronized Mechanism allows automatic weight adjustment, promoting healthy, dynamic sitting.
Conclusion
Klöber's ergonomic solutions emphasize dynamic sitting to prevent the negative effects of static postures. Their chairs are designed to support various sitting positions, ensuring comfort and promoting workplace health.
Introduction
This document analyzes ergonomic seating solutions, focusing on the physiological benefits of various chair features. It highlights the importance of moisture and heat exchange for comfort and outlines the advantages of specific design elements.
Specifications and Features
  • Upholstery and Foam: Open-cell foam without adhesives allows air and moisture to pass freely, dissipating body heat and perspiration for a comfortable seating experience.
  • Backrest Height: A high backrest supports the entire back, preventing muscle fatigue and pain, recommended for prolonged sitting.
  • Seat Tilt: A basic seat tilt of 0° with an opening angle of 92° or 90° ensures even pressure distribution and reduces pressure on intervertebral discs. A negative seat tilt of max. -3° encourages an upright posture.
  • Headrest: An optional height-adjustable and tilting headrest adapts to head shape, relieving shoulder and neck muscle strain.
  • Seat Depth Adjustment: Adjusting seat depth to thigh length avoids knee pressure and improves blood circulation.
  • Lumbar Support: Optional lumbar support adapts to individual back shapes, relieving lumbar strain and preventing hunched posture.
Mechanisms and Systems
  • Seat Tilt Adjustment: Allows individual adjustment to maintain optimal pelvis position and support circulation.
  • Procomfort-Synchronized Mechanism: Ensures constant contact with the pelvis, preventing the "shirt-dragging" effect.
  • Celligence® System: A patented system in the seat and backrest that supports the lower pelvis and thighs, regulates seat surface hardness, and improves blood circulation and posture.
Ergonomic Recommendations
  • Dynamic Sitting: Alternating between forward, middle, and backward positions relieves disc strain and improves well-being.
  • Correct Body Weight Setting: Adjusting backrest counter-pressure to body weight is crucial for good sitting.
  • Seat Height and Depth: Proper adjustments ensure a 90° angle between thighs and calves and prevent knee pressure.
  • Armrest Setting: Armrests should form a 90° angle with arms to relieve spine and muscle strain.
Health and Nutrition
  • Dietary Recommendations: Emphasizes a wholefood diet rich in fruits, vegetables, and whole grains, with moderate meat and dairy consumption.
  • Exercise: Daily exercises strengthen the back and improve intervertebral disc function.
Conclusion
The document underscores the importance of ergonomic design in seating solutions for enhanced comfort, health, and productivity. It provides detailed specifications and recommendations for optimal seating posture and lifestyle choices.
