With TPU cases it's usually a hit or miss.  With this one, my Nexus 7 is a happy tablet.  The back area has a flat, slick, X area while most of the sides retain a textured area that works very well when holding in your hand.  I often surf the web or watch videos while in bed and have had no problems with the case being slippy.  For the money this is a great case and probably the best you will get under $10.
