Smaller size is preferable for a home office. The other two models available at Staples may be great for a commercial business office but the smaller one is perfect for my smaller home office.
As I added under "cons" If chair has small wheels mat will crack over time. This is the 3rd mat I've purchased due to this. Larger wider wheels would negate the situation so the problem is not necessarily with the mat!
The warranty is only 3 years Not lifetime as stated. Your out after 3 years if it cracks. Look elsewhere where there is a real lifetime warranty and you can get proper service..
This mat is excellent in protecting my hardwood floor. It does not slide and has a slightly textured surface. The mat is so transparent that at certain angles it is almost invisible which allows the beautiful hardwood finish to be seen.[...] Much less expensive than the in-store mat and way less than at other retail business supply stores (am I allowed to say [...]?) or online. [...] was twice the price.
Chair rollers dig in to the mat making holes and making rolling/moving around difficult. The chair gets stuck in the holes. You can see the seat roller holes although the holes seem to fill back in later after usage. This does not help while using and moving the chair around though. Suggest making the mat sturdier using stronger material.
