I have an odd shaped desk. This worked perfectly with a small modification made with some strong scissors. Great to buy from the store and get it set at my desk the same day.
Returned item to the store 2 days later. Was too thin chair made grooves and got stuck. Tried to buy next thickness up same size but was not available in the Patchogue store
It did what it was supposed to do however it is thinner than I thought and as a result of that it dimples easily so it does create divots and you have to work to move around. If it were a little thicker that may be corrected
