True - if you are going to use it on a thicker carpet at home for example This is not the perfect chair mat - The cleats are too short and the chair will leave "dents" where its wheels are and where you sit. However the dents pretty much bounce back. The mats made for thicker carpets are twice the cost so this solution certainly works if you cannot afford the others. Rolling an office chair around is much easier now with this mat than without.
No different from the one I paid $24 for but this one cost [$]. After a few weeks use there are already indentations from my desk chair. Avoid this product!
Initially ordered the larger one which took up way too much space. I have just put in new hardwood floors and wanted to ensure the wood was not destroyed by my office chair wheels. This does the job more than adequately and it was a good price.
Unfortunately it will not stay where we put it. It is on a very old smooth commercial floor covering. We have had to tape it down or it migrates and develops a high ripple when furniture stops its movement. That ripple has resulted in serious some serious trips.
