Lancaster Home 45" x 53" Carpet Chair Mat with Scuff and Slip Resistant Textured Top

This is exactly what I was looking for - a perfect dimension to fit between my desk legs, without the unnecessary "tongue" and a heavy weight carpet protector. A bit difficult to slide into place (since it doesn't slide as it's design intent- those little protrusions on the bottom are sharp) so I used a couple wooden dowels, slid it into place and pulled out the dowel rods (pieces of cardboard would work). It did come in the mail rolled in a cardboard box and I had to lie it flat with heavy books to flatten it as the directions indicated - took a day or so but now lies perfectly flat. Nice product.

Rcv'd within 2 days. I like how it is a rectangular mat without the 'tongue'. I had one previously that was too thin for my weight (240) and the wheels of my chair kept sinking in so the chair would not roll easily. No problems with this one.
