It is a perfect size. It is a little thin in every day use. When I (140 lb male) am sitting in my chair the back edges will flair up & family members have caught their feet as they walked by.
What I don't like is when sitting in my chair the wheels put indents in the mat making it hard to move.
This mat says it was made for the thicker carpet per the description of product, it needs to be thicker to avoid the indent issue. I only weigh 168 pounds!
This is the perfect size for my dining room now home office. Chair moves easily without slipping away and it doesn’t leave dents in the carpet. I wish I had gotten it sooner.
