As the aging population continues to grow rapidly, maintaining the health and quality of life for the elderly has become more important than ever—especially for those who rely on wheelchairs in their daily lives.
MATSUNAGA, a leading brand from Japan with over 50 years of experience in wheelchair design and manufacturing, has developed an innovative solution that redefines the standard of seating comfort—aimed at promoting better health and well-being for older adults.

3D SHEET Backrest: An Innovation for Spinal Health

One of the most common issues among the elderly is spinal curvature (kyphosis), which affects posture, mobility, and overall health.
With a deep understanding of these challenges, the MATSUNAGA development team created the 3D SHEET backrest—designed to contour to the individual’s body shape, providing optimal spinal support and enhancing comfort in everyday use.

Key Features of the 3D SHEET Backrest

Naturally supports the body’s posture, helping users sit correctly and reducing pressure points that can lead to spinal issues.

Provides proper weight distribution and support, allowing for longer sitting periods without fatigue or discomfort.

Enhances daily comfort by supporting natural movement and improving overall mobility during everyday activities.

Reduces the long-term risk of spinal curvature (kyphosis) and related musculoskeletal problems.

MATSUNAGA — More Than a Wheelchair, It’s a Commitment to Health
