Though called the Ortho soft, this mattress is not soft at all but extremley supportive and rather firm but just a little softer that the Relaxsan Original Mattress. The Orthosoft is around 17cm thick.
These mattresses are reccomended by certain spinal injuries clinics for people with severe back injuries.
The Orthosoft Vision is the same as the standard Orthsoft but has a Coolmax Cover
The Orthosoft Vision Deluxe is the same as the Orthosoft Vision but thicker at 22cm
Just that bit plusher and more comfortable than the standard Orthosoft for those who want to invest a little more in their sleep
