A 200lb weight on a 5-wheeled office chair is too much for this mat. It does protect the carpet from the deep wheel marks; however the chair wheels create depressions in the mat. Hindsight tells me I should have opted for the heavy pile carpet (I am currently working on ~3/8" pile carpet)
I am pleased. This May seems sturdier than my previous one. Also the delivery was a major help. I’m a senior who would not have been able to transport it from the store. Thanks
