I bought a Super King, Kingsdown, Sleep to live Mattress from Bensons for Beds in 2007, I am now on my fourth Mattress! My problem is, My first mattress was huge, I was not present when it was delivered, I was in hospital So I never got to sleep in it till a week later. When I got home I could not get up on the bed, my partner had to get me a step because it was that high, now that the mattress has been replaced it has dropped a good 4 inches in height. I laso bought a headboard costing £500.00 to match the first mattress height. now im on the fourth, none of these mattresses are the same size, colour or lasted more than 4 weeks without sagging. now I am being told my original bed has been discontinued and a new model has been designed, so my argument is that my old base is not compatable with the new model mattresses and not the same size; i.e width wise. I have written to customer services about this and they have stated that I would yet again be getting a new mattress and a new matress only. This is very frustrating because I am now having to sleep in my daughters bottom bunk for comfort as I suffer too much pain and discomfort and sleep deprivsm.
