You get what you pay for. This immediately started getting indentations on it from when we sit in the chair that is placed on it. It might be better to spend more money & get a better one. I got this one because the one I had before had cracked in several places. I imagine this one will also.
This works good enough and is good enough for the price the only issue I have with it is that it gets dents in the mat that my chair keeps wanting to roll into. I am a small person my chair is a small task chair and my carpet is very low pile... so I'm not sure why this plastic gets deep wheel dents. 🤔
