Chairs & Seating - Sitting Techniques That Support Productivity and Health
By choosing appropriate chairs, you can maintain concentration even during long desk work and reduce physical strain.
Chair Selection Determines Work Efficiency and Health
Modern knowledge workers spend most of their day sitting in chairs. Choosing appropriate chairs is not just a matter of comfort but an important investment directly connected to work productivity and long-term health.
The human body is not designed to maintain the same posture for long periods. Continuing to sit in inappropriate chairs causes various symptoms like back pain, shoulder stiffness, and neck pain. These symptoms invite decreased concentration and significantly impair work quality and efficiency.
The Importance of Ergonomic Chairs
Chairs designed based on ergonomics (human engineering) provide support that follows the body's natural curves. Appropriate lumbar support, adjustable armrests, and seat height adjustment functions enable optimal sitting posture adjusted to individual body types.
Initial investment may be expensive, but considering medical cost reduction and productivity improvement, there's sufficient value in the long term. Chairs are tools used for several hours daily, and considering that products that last over 10 years are common, daily cost becomes very low.
