Protect your hardwood floor from office chair damage that the casters (wheels) can do to the wood over time. When the wheels slide across your floor, they leave tiny scratches behind that may not be immediately visible to you, but if left unattended this could cause very unattractive blemishes to form on your floor. There are a few ways you can protect your hardwood floor from the wheels of an office chair.
Put a commercial-grade area rug down on your floor beneath the office chair. The commercial-grade carpet is thin and tightly looped, making it easier to slide around. Purchase a rug sized at about 3-by-4 feet to allow you room to move around.
Buy an office chair mat. This is a thick piece of rubber that goes down on your floor in front of a desk. It is important that the mat is rubber so that it will cling to the hardwood floor—if it is plastic the mat will slide with your chair.
Adhere a large piece of cardboard to your floor if you are trying to save the cost of buying a mat or area rug. Cut one corner of a large box and lay it flat in front of the desk. Use an adhesive putty that is safe for wood surfaces. Place a small piece of the putty under each corner of the box to keep it attached to the floor.
Replace your chair's regular nylon wheel casters with hardwood floor casters. These are made with rubber wheels to roll safely across hardwood floors. Simply pull the old caster out from the bottom and insert the new ones.
