NOT FIT FOR PURPOSE! We purchased a pillow top mattress just over 2 years ago and it is now the most uncomfortable mattress I have ever slept on. It has dipped on both sides by over 3 inches, leaving a ridge down the middle. After several complaints, the only advice given, was to sleep in the middle!! Absolutely ridiculous, how do 2 adults sleep in the middle! After further complaints we have now been told we have to get an independent inspection at a cost of £48 to confirm its a manufacturer fault, the photos and video clearly show this. REALLY BAD CUSTOMER SERVICE! I will never purchase or recommend this company again! Totally unacceptable customer service, and unsatisfactory goods!
