I bought this only because description said it could be used on all carpet -- actually says on the package that it is for low carpet, just like all the others.
I have been using it for a week and it is soft and bumpy under the chair - won't last long before it tears I'm sure.
How accurate was the sizing? Close but not exact 36"x45"
Please tell us about the quality of the product. Fair--rather bumpy on medium pile carpet
Was the product free of any manufacturer defects? yes
