We are on burber (spelling?)carpet and the pad is so soft the chair creates deep marks in the pad which take a great amount of time to raise back up. The old one I purchased from your store about 10 years ago was fine---it held its shape like it should. This one will not last very long.
Material is soft so I am hoping that means it won't crack like the last protector I had but the softness makes it difficult to roll your chair on when seated as your weight creates dents in the surface.
Once down and in position it works well at just lying there. Unrolling that prickly monster without inpaling your fingers is impossible. You must fetch the Blackberry pruning gloves and then have a go. GOOD LUCK
