The Visco Heaven is a beauty. It is comfortable, stable, and offers good spinal support. Partner disturbance also seems minimal. The cool gel infused memory foam should also keep you cool in summer. Feels and looks very well built. A great bed at a competitive price. Definitely give it a try.
Visco Cool 1000
As you lie on the Visco Cool 1000 you get that immediate soft, sinking feeling. It may be comfortable for some but the spinal support would be questionable. Look elsewhere.
Cool Gel 2000
The Cool Gel 2000 contains the cool gel technology to help keep the heat away if your room is not temperature controlled. It offers very good spinal support and comfort.
