Purchased a pillow top mattress just over 2 years ago, it has now dipped over 3 inches on both sides. After several complaints, we finally received advice, sleep in the middle! How do 2 adults sleep in the middle, who sleeps on top? Further complaints, to be told we will have to pay for an independent inspection at a cost of £48 to confirm if a manufacturer fault, they will only then discuss our options! Absolutely disgusted! They advise a mattress has an 8 year life, clearly not! I will never purchase from this company or recommend and advise everyone to go elsewhere!
