What's the best way to keep my ergonomic chair from scratching hardwood or LVP floors?

Swapping to soft-roll polyurethane casters (80A Shore hardness, 2.5-inch diameter) is the most effective floor protection — they roll smoothly on hard surfaces without digging in, and most ergonomic chairs accept a universal 7/16" stem replacement. Chair mats work too, though they can curl at edges and create a tripping hazard over time. If you're not sure which casters fit your chair, bring the model name when you call — we can match the right part. Find floor-safe seating options at FindOfficeFurniture.com or call 888-719-4960.
