Traditional innerspring mattresses have springs spaced regularly through them, with each spring providing a point of support. Waterbeds provide even support at all points, not just at some. This reduces pressure on both the skin and skeleton of sleepers, providing greater comfort.
The even pressure of waterbeds also reduces the risk of bedsores for people who are confined to their beds for long periods. The beds also provide relief to people with arthritis, rheumatism and back problems.
Waterbeds are also heated. This provides not only a pleasant warm sensation; it can even stimulate blood circulation. The level of heat can be adjusted to provide optimal comfort.
