It might be more logical to think that a seat with all sorts of bells and whistles is going to be more comfortable and better for your posture; however, such is often not true and easily disproved by the T Chair. You could hardly physically reduce a chair any more than it has been in this design, yet it encourages you to sit in such a way that supports your back very well.
Natalia Coll used just two wooden components to construct this minimalist stool. One serves as a stand and it has two tabs in the top that can be fit neatly into the holes of the seat. The T Chair has a 15-degree slant to orient your hips for optimal ergonomics as your lower legs and feet fold side-by-side beneath you.
