Office Chair Mat for Hardwood Floor, 48"×36" Clear Office Floor Mat, Computer&Desk Chair Mat, 2mm Thick PVC Heavy Duty Floor Protector Chair Mats for Rolling Chairs, Can't be Used on Carpet

First, as a floor mat under a chair on hardwood or tile, this would be excellent. It is flexible but good quality, clear, and works exactly as described in the listing. There are warnings all over the listing about it not being for carpet which is an excellent point to make, I had to put these on carpeted floor to uncurl them and they were very slippery so these are definitely not for use on carpet or rugs. I ordered two and they flattened out well overnight but to get the stubborn curl out of the ends I just used a hair dryer for a few minutes on the corners and ends and that did the trick well. I bought these to essentially add a front to two bookshelves to make them safe for some collectibles since my very cute but highly destructive Elkhound really enjoys stealing and wrecking things, especially expensive or rare things. I used large binder clips and outdoor Velcro to affix these mats to the front of the shelves and then trimmed them to the right length which was quite easy. I've had these attached for several weeks and no issues. I am really happy with my creative use of these mats that were a great value compared to similar brands and styles. As a floor mat, excellent. As a front for bookshelves to prevent my Funko collection from getting slobbered on and destroyed, priceless.

Overall, it’s acceptable. I can use it as a mat under my office chair. It arrived tightly rolled, so it took some time to flatten out. The thickness is just okay.

The mat arrives rolled up for efficient shipping, so you need to roll it in the opposite direction to remove the curves. Once you get it flat enough to lay flat on the floor with the weight of the chair on top, it will lay completely flat. On laminate wood flooring, the mat does not slip. It feels like it is made out of a plastic or silicone material that is a little soft and almost sticks to the floor. Maybe if the floor was made of glass and covered with water, then the mat would slide. But on normal flooring, I don't see any slippage. The mat is also thick and strong. My stupid chair has feet that gouge into the flooring, causing physical damage when sitting down. This mat protects the floor and resists damage to the mat from the chair.

Good, however it doesn't stay in place for me

Perfect in saving my vintage hardwood! Bonus, barely visible on the floor. You may need something heavy to make it lay flat for a few days but once its flat, it stays in place.
