Lumpy

We purchased this mattress because the salesperson said it was treated in the factory to simulate pressure so all settling would occur before we received the mattress. Within 6 months of use, there were severe indentations in the bed, and the sides gave out. It almost feels as if you are being rolled out of the bed when you turn. We are normal sized people too. This mattress should last years, but we've had it for 3 and would prefer sleeping on the floor.
