So far so good. It has taken us a few weeks to adjust to having a new mattress. The mattress is comfortable and was delivered promptly.

Visited the Doncaster Showroom, asked a few questions, got good answers, tried a memory foam mattress out. Put a deposit on it and collected it rather than having delivery which was free ( it's for our new purchase in Northumberland).
