Ortho mattress £350, delivered with sagging all along centre of mattress. I was advised the filling takes time to settle and it needs turning every two weeks. After four weeks it is worse. I cannot sleep on the soft saggy mattress as it is nothing like the firm mattress we ordered from the store. Customer Service asked for photos of it, which we did, they said they could see the base was not from Bensons for Beds and therefore it is our fault not theirs, if the space between the wooden slats is more than 7 cm then it is definitely our fault! Nobody had said anything about this when I bought it from the store, despite my telling them I had a wooden bed frame and the last mattress was good on it for ten year. They think it is a comfort issue not a fault with the mattress and an independent inspector will be calling soon to verify this. Customer Services were extremely rude and unhelpful. We shall see what the technician from their independent company says. I can see many other customers have had this same problem with their reject mattresses, is it a scam?
