the mat is probably fine for berber or short-hair carpet. I had it for thick carpet and it is not working well. It keeps moving and I need to adjust it daily
This is the second mat of this type we have purchased from Staples in the last five years. The first one cracked in the middle where the chair was rolled to and from the desk on a daily basis. Each day it was in use for business from 8:30 am to 3:00 pm by the administrative assistant for the business which was run from the home. The rest of the time it was used by the family of three who lived in the house including a young child and her friends while they played games. I believe the cracking was due to the weight of the adult during the day and two children or one adult plus a child using the chair during the evening hours.
When this mat said it was for only 1/4 inch carpet it was actually stretching. This mat is so light weight that it does not give a firm surface for a roll around office chair. It was a waste of money. I am sad I spent the time and money to purchase it. I am thinking about returning it to the store. Not very useful in my office.
The floor protector is a thinner plastic but does what it is suppose to. You can see the indentation of the office chair but it is protecting the floor.
