Bought a new mistress in 2013, we told repeatedly that due to the type and value the mattress did not need turning or flipping. We were told to ignore the instruction book which, as this would cause damage to the mattress. 4 years down the line we the mattress is beginning to wear and Bensons will do nothing as we have been negligent. Had we been told we would be done the care, as were told not too we did not. Also new item when they sent FIRA, the slates have to be no more the 6cm apart.... our at 10. Shame the neglected to tell us this as the time of purchase
