- a head restraint comprising a body and a first and second post extending from the body;
- a first guide sleeve adapted to engage the first post, wherein the first guide sleeve comprises:
- a generally cylindrical sidewall including an undeformed portion and a plurality of wave structures protruding radially from the undeformed portion, and wherein the generally cylindrical sidewall comprises a unitary structure including a metal substrate and a low friction polymer layer;
- and
- a locking mechanism adapted to selectively secure the first post relative to the first guide sleeve, wherein the locking mechanism is detachably coupled to the generally cylindrical sidewall;
- and
