发明名称 Chair Having Legs That Are Adjustable Independently and in a Coordinated Manner
摘要 A chair is provided that permits a chair user to configure the chair to accommodate uneven terrain. The chair user manually grasps a strap, additionally grasps the chair at another location, and moves the strap toward the top of the chair. The strap movement releases in a coordinated manner a group of telescoping leg posts from their fixed securement, whereupon the telescoping leg posts individually adjust to respective heights such that a seating portion of the chair is supported at a level disposition.
