I used a similar cold pac while taking physical therapy for a pinched nerve. After I would do the exercises prescribed for me they would have me lay on the cold pack for 12 to 15 min. I would almost go to sleep lying there on the table. I love the size because your whole back gets the same treatment. I store mine in the refrigerator (not freezer). It is plenty cold, lasts for a long time and is soft and pliable. What I mean is, it is always ready to go. I just take it out of the fridge and place it under my back and relax! It is very sturdy too. Should last me a lifetime. I am careful to not pick it up by the edge. Pick it up in the middle, fold it in half and back to its storage spot in the fridge.
