Bought this 2 year protection plan and come to find out it doesn't even cover simple stuff like our mattress losing it's shape and stability. A mattress should last longer than 1 1/2 years before it starts caving in and the foam and springs start to give. So disappointed. Asurion Protection is a waste of money.
