[0024]The head and neck support structure 1 can be directly affixed to the top side of the backrest of a chair. Alternatively, the head and neck support structure 1 can be vertically adjustably mounted at the backrest of a chair, as shown in FIGS. 7-9. According to this second embodiment, two side rails 3 are respectively affixed to two opposite lateral sides of the backrest 21 of the chair 2 and protruding over the top side of the backrest 21. Each side rail 3 defines therein a longitudinal sliding groove 31, and a plurality of recessed locating portions 32 longitudinally spaced in the longitudinal sliding groove 31. The head and neck support structure 1 is slidably coupled between the two side rails 3 above the backrest 21 of the chair 2, comprising two slides 13 respectively coupled to the longitudinal sliding grooves 31 of the two side rails 3, two spring members 15 respectively affixed to the slides 13, and two positioning balls 14 respectively supported on the spring members 1...
