The main feature of waterbed mattresses is the use of liquid for support, just like air is used in air/dial mattresses. The main benefits are a their unique feel, temperature control and firmness/softness control with some models. With latest improvements in construction and durability of waterbeds there is very low risk of puncturing or bladder leakage.
Most of the past problems have been eliminated but there are still concerns with initial odor, possible noise, weight and maneuverability, and necessary assembly and maintenance.
