Scientific research has proven that back pain can be aggravated by sleeping on a flat surface. The flat surface creates a suspension bridge between the hips and shoulders, keeping them from fully relaxing, and often creating a domino effect in the body as muscles pull into spasm, which then pulls the spinal column out of alignment –- all of which ultimately affects vertebrae, nerves and discs.

Klass Vaki's™ original contoured foam design supports your body while at rest by means of a unique and patented support system specifically constructed to comfort the dorsal and related muscles as well as the lower back, allowing for all of your muscles to completely relax, evenly, while you sleep. The orthopedic body support is simply placed on top of your conventional mattress.

Because Klass Vaki's™ design is well-balanced and offers gentle support for the muscles on either side of the spinal column, all of your muscles have the opportunity to fully relax while at rest - breaking your cycle of pain, and restoring proper blood circulation and oxygen to the affected areas. In addition, when sleeping on a Klass Vaki™, pressure does not build up between you, and your sleeping surface, allowing for your complete relaxation, and therefore much more restful sleep. This effect was examined in a number of scientific studies, and a notable reduction in both the muscle activity and the heart rate of people sleeping on a Klass Vaki™ was documented.

Klass Vaki™ is not a mattress in the ordinary sense of the word. It is simply placed on top of your regular mattress (which must be firm and not sagging) and under a sheet. Then, simply place your pillow on top of the Klass Vaki™, lie down and make yourself comfortable. Know that you can easily turn on your side.
