Although our bed is just 3 years old, it is sagging very badly both sides, despite frequently turning the mattress. Neither my wife or myself are of a heavy stature so having bought a premium bed and mattress (£2450) we would have thought that this should have lasted at least the eight years recommended between replacing the mattress. The staff at the store were extremely helpful and guided us through the steps of submitting our concerns, along with photo evidence. I wish before buying the bed from Bensons, I had read the reviews as I would have given them a very wide birth. Despite submitting the photos, they said that this is to be expected and said they would review the situation from an independent expert of their recommendation, which would no doubt be biased, therefore wasting my time and money even further. I see that other reviews have had similar experiences.
