I appreciate your input, ill buy one this weekend. These floors are newly finished and it would be a total bummer to ruin them. Thanks for picking up on this!
can I make a recommendation sir?
I also have a hardwood floor.. I also have an office chair with plastic wheels - just like yours.
get a mat on that floor ASAP! those plastic wheels chew thru the varnish quicker than you care to think & before you know it, the nice floor will need a re-sand & seal. I talk from experience - took my chair only ~12 months to make the floor look like crap.. @ 18 months it pretty much was down to bare wood
