Instead of a backrest, a low pelvic support stabilises the hips and encourages the pelvis to rotate forward, leaving the rest of the body free to move above and below it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eActive sitting, with the resistance set to you\u003c\/strong\u003e – The motion resistance is individually adjustable, so the amount of work the chair asks of you is a setting rather than a fixed characteristic.
