Benefits of technology

[0006] It is a main object of the invention to provide an improvement on a chair seat to overcome the above-mentioned problems. The chair seat of the present invention includes an upper metallic covering sheet, a lower covering sheet, and a main body. The main body is held in the upper covering sheet, and the upper covering sheet is pressed at a lower circumferential portion thereof to form a compressed step-shaped section, which closely touches and grips the main body. The lower covering sheet has a holding portion, in which the compressed step-shaped section of the upper covering sheet is tightly fitted; thus, the main body is wrapped, and the upper covering sheet is separable from the lower covering sheet for replacement.

Problems solved by technology

It takes relatively much time and labor to assemble the chair seat because screws are used to fix the lower covering sheet to the main body.
And, the seat can't be rapidly dismantled for replacement and repair of its parts.
