Sealy Sydney Mattress

We bought this Sealy mattress in 2011 it was damaged and Bensons for beds did replace it. After just under three years we moved it to decorate and water poured out of it ruining the carpet. Bensons sent someone to see it and the report said it was not faulty. We dried it out in a very sunny open window which took three days. Since then I have had numerous problems including aches and pains, waking up very stiff and not sleeping well with a dry throat. My husband has had a cough and numerous nose bleeds. We decided to buy a new mattress after five months it had to be a cheap one as We could not afford another £1000 and the problems seem have gone. The mattress did the same again and is soaking wet. I rang bensons again and they did send the same person again who, after seeing how wet it is and admitting it smells damp has said it is not faulty. I am appauled by their comment as the sales assistant told me it would last for twenty years not three. We think this is a manufacuring problem that they should be recalled. DO NOT PURCHASE THIS UNDER ANY CIRCUMSTANCES. We are very upset and disappointed
