I have a sliding table that goes over my bed. I have my computer on it. A few books. Water. It’s not an office chair I sit on. So this light sheet of vinyl over carpet does the job fine. I don’t recommend it for putting a daily office chair over it as that won’t hold up.
This was totally not what I expected. The mat is too soft and the chair wheels sinks into the carpet. Chair still won't move or roll! Look for a better item!!!
