A 3-legged stool will never wobble, even if the floor surface is uneven, because all 3 legs rest upon the surface where it stands.
Can be used as a side table.
No assembly required.
Stackable, so you can have a few on the side for extra guests without taking up too much space.
Can also be used in bathrooms and other damp areas indoors.
Easy to clean and maintain, since it’s made of polypropylene plastic.
