Choosing the right caster depends on floor type, chair stem size, and load. - Floor protection: PU wheels guard floors from scratches on wood, tile, or carpet - Stem fit: verify 7/16" diameter and 7/8" length for compatibility with common chair sockets - Load rating: ensure total capacity meets or exceeds your chair setup
