Read a review that this was incredibly hard to unroll but cannot relate, unrolled like any other floor mat and gets flat over time.

It's terrible, it's barely thick enough to support a chair, the wheels make dents in it and they get stuck there, but the worst thing is the smell, 10 days I have had it and it still stinks the room out, you can smell it in the hallway at night, it smells like dirty rubber gloves, I am going to throw it away soon if it doesn't stop

Mat was thick and a little bit tough to roll out initially but I just needed to add weights to hold it down. Thick and solid feeling, my chair doesn't roll as much as I expected – but I mostly got it it is to protect my carpet and I think it will do the job.

Arrived on time which was great. Thought it would be easier to slide my chair on rather than carpet but it's pretty much the same. But still good. Depends on carpet you have I guess.

Wait for a sunny day and leave out for about 3 hours. That will leave the mat flat as a pancake. Good quality and doesn’t smell like rubber.
