Description

Technical Field

[0001] The utility model relates to a piece of furniture, more specifically, to a chair structure. Background Art

[0002] Chairs are common furniture in daily life. Chairs are designed with ergonomics, and people can relax and rest when lying on them. Therefore, chairs are widely used in hospital accompanying chairs, lunch break chairs, outdoor leisure chairs, etc. At present, many chairs are foldable, which are more flexible and practical, occupy less space, and are easy to carry. They are often used for travel and leisure, office naps, disaster relief and resettlement, etc. In order to improve the comfort of chairs, chairs are generally equipped with headrests. The common chair headrests on the market are connected to a long elastic rope, and the two ends of the elastic rope are sewn on the headrest. The headrest is put on the chair through the elastic rope. This method not only wastes materials, but also makes the headrest easy to slip off. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides a chair structure, in which the headrest is conveniently connected to the chair, the upper and lower positions of the headrest are conveniently adjusted, and it is not easy to slip off.
