Hardwood floors require caster wheel types that will not damage the floor, either by marring or marking. Choose selections with soft treads; use thermoplastic rubber (TPR), urethane wheels, neoprene or polyurethane for optimum floor protection. This group of wheels is also highly recommended for laminate floors, vinyl and linoleum floors, and tile floor surfaces. When unsure of whether a caster will be used primarily on carpet or hardwood, it is best to choose a soft rubber wheel caster which will prevent costly damage to hardwood and laminate flooring. Also, our valued customers tell us that these casters work great on floors with epoxy coatings, especially the Softech models, which are tops in the industry for soft rubber chair casters.
