Abstract
A tube-type watermattress has a plurality of elongated tubes disposed in a head-to-toe direction in the mattress. A wave dampening insert enclosed in each tube has a center portion which is substantially thicker than the rest of the insert to provide additional firmness and 'lumbar' support in the area of the mattress where the lower back or 'lumbar' of a person resting on the mattress is usually disposed.
