Some very famous people were involved in the creation of the first office chairs. Thomas Jefferson, the famous American inventor, was the first to add a swivel option to his office chair. Sometime later, Charles Darwin, the renowned scientist, added wheels to his chair so he could roll around the office.
Today, an average office worker spends about 10 hours every workday sitting in an office chair. That’s why any malfunction on the chair the worker is using can be a consistent cause of irritation.
We here at Boke Furniture are very aware of this and consider this fact when manufacturing our products. Most office furniture manufacturers use a similar approach, but let us take you through our process.
Step One: Creating the Chair Structure
The first step we go through is the creation of the chair’s structure. That is the base for the chair, to which we later add elements that make it more comfortable.
The manufacturer uses hydraulics to bend 14 gauge steel tubes to create the base for the cushion. The steel bars are then welded together with the middle of the base, and they serve as a frame for the mechanism that adjusts the chair’s position.
S-shaped springs are added from the front to the back of the base hooks, which serve as a web of suspension that provides flexibility to the chair base. The base is completed after the springs are clipped to the steel rods.
The back frame is created by combining the chair’s pine to the armrests and, depending on the design, other attachments.
Finally, the worker grinds the spurs to ensure they are smooth and attaches the back frame to the base.
Step Two: Creating the Upholstery for the Chair
The upholstery is created in a separate department of the factory to conserve time. The material designated for the particular chair design is cut to fit the measurements provided. With a cardboard template, the worker ensures that the material is cut with precision.
When all the pieces have been prepared, the cushions for the backrest and the base are cut to fit the design. The foam’s density will depend on which part of the chair it’s supposed to be fitted to.
After this, slits are added to the foam, and the material is marked using chalk to ensure it corresponds to the slits in the foam.
The chalk lines are then aligned with the material as it is sewed together.
Step Three: Chair Assembly and Packaging
At this point, the worker adds a plastic cover to the back of the chair and attaches the sliding plate to the base.
After this comes the installation of the hydraulic cylinders, which gives the height adjustment feature to the chair. It also allows the chair to rotate in a full circle both in the left and right direction.
The cylinder is then attached to the base of the chair.
This is the basic process, and there are other steps involved for chairs that have more complex designs.
