Definitions

  • the present invention relates generally to a furniture and more particularly, to a base seat adapted for being used with a bed or a chair.
  • Conventional bedsteads and chairs have generally a stationary structure. With continuous improvement to people's living standards, more and more beds and chairs having various swing functions are developed and commercially available to provide more comfortable and relaxing user experience.
  • rocking chairs or swingable beds encountered many technical challenges. For example, as an article carrying body weight, a swingable design may be more complicated in structure and weak in structural strength than a stationary structural design, resulting in that not only the problem of low life span but also the problem of high operation noise caused by movements of elements need to be resolved. Further, the design of swing mode is also important. A swing mode that is not ergonomic may cause discomfort, such as dizziness, to user.
  • the conventional rocking chairs or swingable beds usually provide a reciprocating swing motion in a single direction, inevitably resulting in that user may feel mental fatigue and even physical fatigue after using the conventional rocking chair or swingable bed for a certain period of time.
  • the present invention has been accomplished in view of the above-noted circumstances. It is an objective of the present invention to provide a base seat for being used with a bed or chair, which has an ergonomic swing function to make a user feel more comfortable and relaxing.
  • Another objective of the present invention is to provide a base seat for being used with a bed or a chair, which has a firm and stable structure, a long life span, and a low noise in operation.
