Description
- 1. Technical Field
- The invention relates to chairs, particularly to a width-adjustable chair.
- 2. Related Art
- Chairs are necessary in our everyday lives. Comfortivity of chairs is a very important factor, especially for those people who sit on chairs in a long time.
- Conventional chairs always provide an adjustable function for backs, armrests or stands. But a width-adjustable chair does not appear in the market. However, some specific users such as a person in a hairdressing salon or an invalid in a hospital must sit on a chair with adjustment and restriction of width to prevent them from moving. Furthermore, a chair will provide better support and comfort when the chair can closely encompass a user's breech.
- An object of the invention is to provide a width-adjustable chair, which can provide better support and comfort.
- To accomplish the above object, the chair of the invention includes a stand, a first seat and a second seat. The stand includes a mount and a supporting bar horizontally connected thereto. The first seat connects to a side of the supporting bar. The second seat connects to the other side of the supporting bar to associate with the first seat. The first seat and the second seat can be horizontally moved to adjust a distance therebetween.
