This office chair mat for hardwood floors was perfect because although I don’t have hardwood floors, I have tile and the grout lines make it really hard for my computer chair to move around. Once I put this down, I no longer had a problem with the wheels on the computer chair, getting stuck in between the tiles. It was night and day difference and made it such a smooth transition, moving forward and backwards. The mat was hard to unroll, but not impossible for one person and I did have to stack heavy things on it per the instructions so I just used books to flatten it out. As you can see from the pictures, the size was perfect and it was just thick enough!
