Car Seat as Office Chair
Car seats can be modified into office chairs, with the Buick GL8 car seats and the middle-row seats of the Toyota Sienna being common modification choices.

Buick GL8 Car Seat Modification
After being removed from the car, Buick GL8 car seats can be easily modified into office chairs. Modification Method: By adding a base and caster wheels, smooth movement can be achieved, and the backrest can be adjusted to a flat position. Many netizens spend between 300 and 500 yuan to obtain a level of comfort comparable to that of a thousand-yuan ergonomic office chair. Seat Advantages: The GL8 seats are designed with a focus on comfort, typically featuring armrests on both sides. They are spacious and comfortable, conforming to ergonomic design principles and providing good support. Their spacious and comfortable nature has even earned them recognition as the seats for official vehicles in major diplomatic events. Modification Plans: There are multiple options. The most common one is to replace the middle-row seats with more powerful aviation seats that offer functions such as forward and backward movement, rotation, electric massage, ventilation, and heating. A simpler and more cost-effective plan is to focus on modifying the seats into home computer chairs or office chairs. The operation process usually involves obtaining the middle-row seats of the GL8, preparing an adapter plate (which can be purchased ready-made or made by drilling holes in a steel plate), and a swivel chair base with caster wheels. Finally, the adapter plate is fixed between the seat and the swivel chair base, and the wiring is connected (if the seat has functions such as USB charging). Modification Disadvantages: DIY modifications have some drawbacks. For example, the overall sitting height after modification may be relatively high. Some users have reported that the seat height reaches 53 centimeters after modification, and for a person who is 180 cm tall, their feet can barely touch the ground, which may affect their sitting posture.
Toyota Sienna Middle-Row Seat Modification
The middle-row seats of the Toyota Sienna come in fabric materials, and many people like to use them to assemble computer chairs. Although there is no detailed introduction to the modification process like that of the Buick GL8, it can be inferred that the modification idea is similar to that of the Buick GL8, that is, to transform them into seats suitable for office use by adding appropriate bases and components.
