Large chair mat (Benton, east of downtown)

Large chair mat/platform, very sturdy, great for office roller chair on carpet.

Approximately 4’ wide by 5’6” long, laminate flooring on plywood. Not exactly professionally built, but served me well.

Second picture also shows comparison with plastic chair mat, 3’ by 4’, which I can throw in if desired. It was labeled “heavy duty”, but doesn’t perform nearly as well (hence the custom-built platform).
