Mat is not strong enough to support standard desk chair.

Mat wrinkles and chair won't roll on it

I do not recommend this mat for medium or deep pile carpet.

This is not going to be a smooth mat to move around on.

this mat is junk I would never buy again!

My carpet might be too fluffy or this mat is too soft

More like a mat from a bathtub

The mat is so soft and malleable that an office chair leaves indents without a person even sitting in the chair

This mat is perfect for protecting the carpet under my step-daughter's art table
