Hole In Plastic Stools Explained: Design helps stacking, lifting, drainage; shows smart engineering

The small opening in plastic stools boasts multiple design advantages. It helps in releasing trapped air when stools are stacked, making them easier to separate. This hole doubles as a handy handle for lifting and moving purposes. Additionally, it promotes water drainage, avoiding seat pooling. On top of that, the design minimizes material use, resulting in a lighter stool overall.
