POSTURE IS EVERYTHING!
Research confirms that slouching and similar seated postures can cause backache, headaches, fatigue and poor concentration
The key to healthy posture is lumbar and pelvic support. Lumbar support alone is not enough.
Ergonomic principles state that your chair should fit you. With Lumbar and Pelvic support, your chair can be optimally adjusted to fit you, not you posturing yourself to fit the chair.
