I did not need anything special-just simple. The product is ok however it is too thin for the carpet that I have. Even though I measured the depth of my carpet that seemed very close to what was on the showroom floor and assured by sales staff that it will work with the chair that I had recently purchased at same Staples it has turned out to be a mistake. Dents developed on the mat from the chair within 2 days. I am assuming that my carpet is thicker than I thought. Therefore I likely purchased the incorrect type and need a thicker and stronger mat. Be careful and do not buy this cheaper model unless you have extremely thin carpet. A big mistake. It’s worth any extra expense to be right .
The Chair Mat is pretty flimsy. Definitely not for anything but a solid floor or flat carpet. I would have returned this but my kid grabbed it and started using it immediately (virtual learning). I don't expect the Mat to last long and maybe when I replace it there won't be a pandemic so I can actually inspect the materials for durability.
This chair mat is the only one that I found that is thick enough that works on thick carpet and holds the chair so it doesn't sink into it rendering is useless. Great buy and great product.
Purchased tis mat about 3 weeks ago. Says its for medium pile carpeting not at all accurate. After about 3-4 days of use the chair wheels started making impressions into the mat. Will be returning as soon as possible.
