How do I protect hardwood or luxury vinyl floors from ergonomic chair casters?

Hard floor protection specification at OfficeFurniture2go.com uses soft-roll polyurethane casters as the primary solution — 80A Shore hardness, 2.5-inch diameter, universal 7/16\" stem. We specify this caster type automatically for all orders where hard floor installation is indicated. Chair mats are a secondary option for users who prefer not to change casters. We include floor type in our order specification checklist — don't discover the wrong casters after installation. Call 1-800-460-0858.
