The Evolution of Deep Fill Softside Waterbeds: From the 1970s to the 2025 Perfection
In the 1970s, the world of sleep was revolutionized by the introduction of waterbeds. These innovative sleep surfaces, filled with water, promised unparalleled comfort and a unique sleeping experience. Among the early innovations were Softside models designed to look like traditional mattresses. And while later designs varied into Shallow and Mid-Fill models which we’ll be addressing in Parts 3 & 4, early Softsides were designed to 9” Deep Fill specifications established for the original Hardside Wood Frame Waterbeds being produced at the time.
The Deep Fill Softside Waterbed Era: 1970

The 1970s were marked by a spirit of experimentation and a desire to break free from traditional norms. Waterbeds, with their fluid support and promise of a weightless sleep, fit perfectly into this zeitgeist. As the assembly processes of the first Deep Fill Softside Waterbeds were often fairly intricate, early designers often focused on simplifying product set up. Relative to this challenge I rendered the adjacent pencil illustration nearly 50 years ago promoting one solution. Albeit the concept looked good on paper, as King size models weighed up to 200 pounds and boxes were large and unwieldy (much like a refrigerator), in reality shipping and delivery required a sizable vehicle to transport a couple of stout delivery people to install. As complexities were continually resolved, Deep Fill Softside Waterbeds ultimately became a symbol of luxury and modernity. Often associated with the counterculture movement and appealing to those who sought an alternative lifestyle. The sensation of floating on water, combined with the bed’s ability to conform to the body’s contours captured the imagination of a generation seeking new ways to relax and rejuvenate making Deep Fill Softside Waterbeds a highly sought-after item in the 1970s.
The Evolution of Deep Fill Softside Waterbeds: 1980s-1990s
As the 1980s rolled in, the waterbed industry continued to innovate. The evolution of Deep Fill Softside waterbeds marked a significant shift. Unlike their Hardside counterparts which often included bruise inducing Wood Frames, Deep Fill Softside Waterbeds featured a water-filled mattress encased in a foam perimeter, which was then covered with a fabric casing. This design made the beds look more like traditional mattresses which facilitated the use of conventional size sheets and bedding, making them more appealing to a broader audience. Additionally Deep Fill Softside waterbeds were becoming easier to assemble and maintain as the assembly process was simplified.

The InnoMax Perfection: 2000s-Present

Fast forward to the present day, and the waterbed industry has continued to evolve. One of the standout designs in the modern era is the InnoMax Perfection Deep Fill Softside Waterbed. This design represents the culmination of decades of innovation, combining the best features of traditional waterbeds with modern technology and materials. The InnoMax Perfection is designed with user-friendliness in mind. The assembly process is straightforward, with clear instructions and fewer components. The bed features a deep fill water chamber, providing ergonomically designed internal support complemented by stretch top vinyl with fluid support like earlier models but with enhanced comfort and stability. The water chamber available with a variety of wave reduction options, is encased in an exclusive Memory Weave Interlocking M-Rail Power Edge that provides a smooth transition from foam perimeter to fluid support which is then covered with a Luxurious and Fashionable enclosure. One of the many key innovations in the InnoMax Perfection design is the use of advanced materials. The exclusive Memory Weave Interlocking M-Rail Power Edge is made from high-density foam and durable fabric providing contouring support from head to foot and side to side. The M-Rail design is also unique in that it does not require hardware, extraneous frame work or recessed foundation cavity, all of which amount to a simplified no-tools required set up installation. The Fashionable enclosure is made with a Luxurious Low Tension Stretch Knit Cover Panel, offering a soft, breathable surface that enhances comfort. And versus over-stuffed pillow tops, the Stretch top provides the original form fitting flotation benefits of pressure point reduction and temperature control thereby optimizing blood circulation for a deeper more rejuvenating sleep. Depending on support package the InnoMax Perfection waterbed may optionally come with dual heaters and digital or analog thermostat controls, allowing users to adjust their sleep environment to their personal preference for year-round comfort whatever the weather.
