Keep well away. All the promises are just "Con sale talk. When they promise so much like one can change a matress if it does not suit your requirements. What a load of codswallop, they have every talk out angle available. And then expect you to fork out some £500 for a new mattress after spending around £2000 on a totally new set up. My warning is keep away and look elsewhere for a company that offers a truthful reliable service. After sales service is disgustingas is the floor personell on the shop floor. Reminds me of the dicwy companies from the 1960's full of con artists.
