I only weigh 150 lb and I am using a executive chair with 5 rollers. the weight of the chair on the mat causes depressions making it difficult to roll around on the mat.
Bought to use over plush carpet for home office. I only weigh about 135 lbs. but my chair sinks into the mat making it very difficult to move the chair. I think if this product were thicker or made of stiffer material the chair would glide easier. Perhaps it would work better over commercial grade carpet without a pad. Overall not very happy with this product.
pretty good price still comes up to [$] which is not cheap !but so far so good chair slides pretty easy not perfect.you can get those cheaper at [...] for like [$] i think.
