I was recommended to buy a certain mattress by dreams staff due to my back condition, I had an issue after a few weeks qhere the bed sinks. As I complained they told me I had to keep rotating the mattress over for a few months. They sent me a new mattress to rotate this one instead which I had insured for 4 years guarantee. So after 2 years I didn't want to complain but it really hurts my back and I called the engineer but he said there is nothing wrong with the bed. The bed looks fine but after 15 minutes it sinks and they don't want to do anything about it. They told me to call the engineer in 6 months time again. Which is ridiculous as they are just trying to deal the warranty out. I asked and would pay for a better one but they don't want to do that.
