This is a bar stool from my flat.  They are a great example of moments and compressive force together.  Unfortunately they are completely hopeless.  No back support and poor area of contact with the ground.  The forces tend to be almost always biased wherever I am sat on it, making the stool feel unbalanced, the force applied on the foot rest only make things worse.

Moreover the poor choice of materials make the seat very uncomfortable as the padding is extremely thin combined with reactive force from the stool.  They have been repaired several times within the last 6 months.

At least they make great miniature tables for having dinner on.
