I bought this product to go to football games, the Hollywood bowl (outdoor theater) and I love that its not cheap material.  the corners are reinforced and the blanket is a plus.  The reason why i dropped it down from a 5 to a 3 is because 1 it is a little pricey for not having a little more cushion.  They could have used a condensed foam to  keep the slip design and provided the comfort.   I actually have to use the blanket they provide as a cushion and bring another blanket if its a cold night
