Benefits of technology

The present invention is a chair with an armrest that has a function adjusting space underneath the seat. The chair has multiple seat support frames that extend from a center portion of a leg support post towards the seat, with the seat being supported at its edges and at its corners. The function adjusting space can be easily incorporated without interfering with the armrest, and the chair is designed to be easily operated and see the position of the operating part. The chair is also transparent or translucent to improve operationality and allow for easy viewing of the operating part. The chair is secure and comfortable, and can be easily adjusted for different users.

Problems solved by technology

However, if a bulky seat support using a block or a link locates under the seat, there is a problem that it is difficult to secure a space to arrange an operating lever to be mounted on the seat support.
In addition, since this chair is so arranged that a shell or a frame covers most part of a bottom of the seat and an operating lever is completely covered by the seat when seated, there is a problem that it is difficult to see a position of the operating lever.
