Are these safe for my hardwood floors?

Yes! Our chair caster wheels will prevent your hardwood floors from being damaged or scratched. We guarantee this because they are made from soft polyurethane rubber, which provides 100% protection for any hard surface. No scratches, smudges or any other marks. They are also perfect for laminates, engineered flooring, ceramic tiles, terracotta tiles, vinyl, and low pile Рoffice type carpet.
