Like Mr James Burrows, we too ordered a memory foam mattress which after 2 days showed signs of severe sagging. We were told it was normal settlement ! after several months it was worse and again Bensons sent out their inspector who looked at our frame and declared that the springs were too far apart to support the mattress. Admittedly this a beast of a mattress is heavier than the sealy orthopedic ones we had over 20 years, but apparently Bensons declare this as accidental damage and for the price we paid, would have expected batter from them and not have more expense to pay our own inspector ! would never buy anything there ever again
