Chairs should be made of steel that meets ASTM A36 or ASTM A572 Grade 50. Strength: Materials should have a minimum yield strength of ) and a minimum tensile strength of 2. Geometry and Dimensions To make chairs better, rigidity is key. Minimum Height: A minimum chair height ( is recommended, but for improved stability, use if the base plate is or thinner.

: These plates are typically welded to the top plate and the shell. They must have a minimum thickness (often the greater of 0.5 inches or ) to prevent buckling.
