The 42" Square Glass Chair Mat is individually packaged with Styrofoam protection inside a cardboard carton to help ensure safe arrival.

Round glass chair mat protecting the floor of a home office

Protect your floor without covering up its natural beauty.

A glass chair mat brings a clean, modern look to home offices and professional workspaces, while its clear design lets hardwood, tile, and other flooring remain visible beneath your chair.

Every mat is 1/4" tempered safety glass with a flat polished edge, so it stays rigid under a loaded chair and rolls easily, year after year.

Tempered glass is 4-5 times stronger, and more heat and scratch resistant than standard annealed glass.

The tempering process strengthens the glass, and if broken, tempered glass crumbles into small granular pieces, eliminating the danger of sharp edges.

Invisible Shield nano-scale glass coating packets

Every mat ships with an Invisible Shield coating, clear rubber bumpons and clear plastic discs — nothing else to buy.
