Bada is a chair designed to encourage regular changes in sitting posture. Long periods of sitting place added pressure on the lower back. When a user leans into a bent posture, the seat plate rotates and creates an inclination of about eight degrees. The body then slides slowly, so the user is prompted to sit upright again. The body of the chair is made of solid white oak, and the connecting bar is made of stainless steel. Curved forms express the rotation and sliding of the seat. The chair measures 500 mm in width, 580 mm in depth and 750 mm in height.

- Unique Properties
- A chair that allows you to fix your posture through the discomfort
-
Bada is a chair that allows its users to sit by changing their posture regularly through discomfort. Obviously, it is uncomfortable when the users’ sitting positions are changed involuntarily. However, on the other hand, this designed discomfort can keep them healthy and maintain the correct posture. - Dimensions & Packaging
- W500mm x D580mm x H750 mm

- Rotation & Slide
The crooked posture rotates the seat plate and creates an inclination. Hence, the inclination created by the rotation gradually lowers the user's position. This leaves the user no choice but to change their sitting posture.

Material
-
White oak solid (body)
Stainless steel (CD-Bar) - Design Challenge
- The entire shape of the chair is designed in a way that the curves meet each other with a purpose to metaphorically express the process of the seat rotation leading to slope and sliding.It was particularly difficult because it was the first time to make a chair using wood, and there were many trials and errors because it was possible to make a form only by knowing the properties of the material.
- Project Duration
- The project began in Korea in March 2021 and was completed in Korea in November 2021.
- Operation Flow
- Modern people spend a lot of time sitting. Sitting for a long period of time causes various lower back problems. Therefore, you need to change your posture regularly while you are sitting. Bada is a chair that allows you to be able to fix your posture through discomfort. As the users’ sitting positions turn into a bad posture, their bodies will slide slowly, then they will be forced to change their posture. As a result, the designed discomfort feeling is able to help the users stay in a healthy and correct sitting posture.
- Research
- We needed to figure out the appropriate slope to make the posture uncomfortable when the posture is bent, although it is usually not uncomfortable. We found an appropriate slope while producing prototypes using isopink and prototypes using wood.Based on the seat with a height of W450 mm × D450 mm × H450 mm, the slope of 8 degrees was judged to be the most appropriate and the result was significant.
- Inspiration
- The increasing sitting time
-
Modern people spend a lot of time sitting everyday. Compared to the standing position, sitting down on the chair causes twice the pressure on the lower back, which is a major cause of lumbar disk disease(herniated disks). During COVID-19, as the time spent at home increased, sitting for a long time has become a routine. To avoid sitting on a chair for an extended period of time with a sloppy posture, a change in your sitting posture periodically is needed.
