I'm very disappointed in the quality of the mattress I bought. More so that I paid £250 for the mattress l. If I had paid £150 I would have not complained. I have seen better quality of mattresses cheaper. it is atrocious. The customer service is not existent. It's like talking to a robot. Instead of responding to your complaint you get a generic cut and paste email which does not even respond to your query. I would not buy from this company ever again based on their customer service. If they had compromised I would be happy to pay more and get a better replacement. Apparently firmness is subjective. I know in a week the mattress will have a dent in it because of the quality but it's got a 5 year gurantee. I know when I complain it's falling apart they will just fob me off. We will see...
