Bests & Worsts Reviews from Amazon

I rarely write reviews for things, but I couldn't in good faith let this mislead anyone else into buying it. My purpose for the purchase: I wanted a sturdy mat for my desk and gaming chair that looked nice and protected my newly installed carpet. Considerations: - My height (6'0") - My weight (230lbs) - My gaming chair's weight (66lbs) - I'm a writer and gamer so I will be stationary for long periods of time (hours). - The carpet is medium plush density and brand new. Issues with product: - Chair sinks significantly into the mat (about 1/4 inch) - Chair doesn't roll smoothly due to it sinking into the mat. - Mat moves whenever I move my chair. This is also because the chair wheels sink into the mat. - The mat lifts at the edges when the chair wheel is roughly 6" away from the edge, thus the surface area you can roll your chair is reduced by 6" on all sides. Caveats: - Combined weight of myself and my chair is just under 300lbs. - Carpet has a medium plush density. - I'm stationary for long periods. Theory - It's possible that the mat is not designed to hold this much weight. Test Theory: - Had 5 year old sit in chair for 30 minutes. - 5 year old weights 34 lbs. - Chair weighs 66lbs) - Sat and played Sesame Street games for 10 minutes. Result: The chair had significantly sunk into the mat from a combined total of 100lbs, stationary for 30 minutes. Conclusion: The mat deforms from 100lbs within 10 minutes. Personal Opinion: Don't buy it. Doesn't perform the function intended. Even if I attempted to reuse it for storage purposes, it will deform and sink into the carpet with only 100lbs.
