There are 3 types of mats in the market; 1. Cork 2. Cotton 3. Plastic. 1. Cork is considered the best material as it provides very good cushioning. If you buy a quality mat, the grip is taken care of. Also, it is a natural material. 2. Cotton Mat - Cotton is also a very good material, but is recommended only for light to moderate practices. And beginners face problem with it due to lack of cushioning. 3. Plastic - Most widely used mats. But avoidable for three reasons - Carcinogenic material, heats up with long practice sessions and is not an environment-friendly alternative.
