tres épais mais laisse tout de même des traces des a l emplacement des roues de ma chaise

Good value and does the job.

It works. Takes a bit to fully roll it out and get it flattened. The spikes are pretty sharp so be careful unrolling it, keep your face away in case it springs back. Might be a two person job for some people.

Its pretty good and decent, not flimsy at all for the price.

The size is perfect. they could be a bit stiffer as the casters of my chair sink in a little to the carpet and makes it more difficult to roll

Quality good. Giving 4 stars because it is very difficult to unroll and flatten. You need 2-4 people to unroll it. Instructions tell you to put something heavy on corners and it will be read to use in 4 hours. We had to put all kinds of heavy items not only on the corners but all over so it would flatten out but it took 3 DAYS before we could use and over a week later, still not completely flat.
