An adjustable connection joint has a partially shaped spherical member attached to a first member to be adjusted with respect to a second member. A slidable base member slides in a bushing which is attached to the second member. A bolt extends through a washer that spreads a slotted end of the slidable base member against the bushing. Tightening the bolt pulls a locking member against an inside of the partially spherically shaped member and pulls it against a conical cavity on an end of the slidable member. Tightening the bolt concurrently locks the slidable member in the bushing and locks a position of the partially shaped cylindrical member in the conical cavity at the end of the slidable member.

A seating device includes a headrest movably connected to a seat body. An adjustment mechanism is provided to adjust the position of the headrest relative to the seat body. An operating unit has a driving member to actuate the adjustment mechanism, and a handle portion bending from the driving member. The driving member is movable between non-operative and operative positions. In the non-operative position, the handle portion abuts against the headrest. In the operative position, the handle portion protrudes outward from the headrest.
