As a neutral evaluative customer I can recommend to all who like myself suffer for years from back pain with a clear conscience this mattress. The sleeping comfort is excellent. The adaptation of the mattress to the body is optimal, but is important that the body weight corresponding hardness is selected. This is obviously very well balanced at this mattress. Climate behavior is also excellent, the mattress is neither too cool nor warm it up too much. A total of definite recommendation if you want to wake up in the morning as an older person without major back problems.
