Had a faulty mattress replaced three years ago, was upgraded due to numerous issues with the previous mattress and failed delivery/service. Replacement mattress has developed a fault where the side wall has collapsed after 3 years. Numerous texts, calls and messages later they have agreed has fault but are trying to deduct the upgrade and provide me with the price of the original mattress which was 8 years old (with a 10 year guarantee) when replaced 3 years ago. Impossible to deal with, I am issuing a court summons as had enough with this kind of service. Don't use them!!
