Best Waterbed Mattresses – Top Picks and Buyer’s Guide

Written by Tuck Staff

Quick Overview

Waterbeds were a popular bedroom fad during the latter half of the 20th century, but today they are not as common. However, many sleepers continue to enjoy the unique sensation of lying on water and many brands continue to manufacture these beds.

Waterbeds come in two common types. Hardside models have a wooden frame to contain the water chamber; they are often heavy and spacious, but also relatively inexpensive. Softside waterbeds contain the water chamber within a frame padded with foam and fiber padding; they typically look and feel like standard mattresses, and have higher price-points to reflect that.

Waterbed buyers can also choose between free-flow, semi-waveless, and waveless designs. Free-flow beds produce dramatic undulations at the surface, resulting in a wave-like sensation that many sleepers enjoy; others, on the other hand, dislike the sensation and many feel seasick as a result. Semi-waveless beds have more subtle undulations, resulting in a more balanced sensation, while most waveless waterbeds live up to their name and do not produce any undulations whatsoever.

Read on to learn more about waterbed types and features, buying tips, and warranty considerations. Below we’ve listed our top four picks for waterbeds sold today. Our choices are based on a combination of verified customer and owner reviews and intensive product research and analysis.

Hardside waterbeds offering a waveless surface are somewhat rare. The INNOMAX Genesis 800 eliminates waves with a complex, four-layer reduction system of foam bolsters and gravity suspension, resulting in a tranquil sleep surface with excellent motion isolation. The waterbed is also constructed with a foam pad that runs across the midsection, resulting in isolated support to the sleeper’s lumbar region.

The INNOMAX Genesis 800 also includes a contoured, 24-millimeter vinyl cover, which makes the bed resistant to scratches and tears in the surface. However, the surface offers close contact to the water, allowing sleepers to experience the therapeutic floating sensation of classic waterbeds.

Another benefit of the Pillow-top Softside Waterbed is its sophisticated, digital heating system.

Buying Guide – Shopping for the Best Waterbed

The waterbed was a bedroom staple during the 1960s, 1970s, and 1980s. In recent years, many sleepers have switched to more traditional mattresses. Beds made with springs, foam, and latex tend to provide better overall support and pressure relief. They also isolate motion transfer to a more noticeable extent and are much easier to maintain. However, many sleepers enjoy the undulating sensation of sleeping on a waterbed. Waterbeds also carry certain advantages over other mattress types, such as low prices and shorter break-in periods.

Read on to learn about common waterbed types and their components. This guide also includes important considerations for shoppers, maintenance tips, cost analyses, and some additional resources.

Common Waterbed Types and Features

Most waterbeds sold today fall into one of two categories based on how the water is contained:

  • Hardside waterbeds have water chambers held inside durable wooden frames, which help the bed maintain a consistent shape. Despite the name, a hardside frame may be made of softwood or hardwood. Hardside waterbeds are exceptionally heavy with or without water; on average, they are also the least expensive of the two waterbed types. Some waterbeds designed for hardside frames do not come with frames of their own.
  • Softside waterbeds contain the water chamber within a frame made of foam and fabric upholstery; at first glance, these waterbeds often look like conventional mattresses. The top is often padded with foam and other comfort materials, as well.

Beyond the frame material, waterbeds also differ in terms of the surface feel and wave level. For this criteria, waterbeds usually fall into one of three categories:

  • Free-flow: The water billows and undulates, resulting in noticeable waves. No bolsters or baffles are used.
  • Semi-waveless: Small foam bolsters and/or baffles contain the water chamber, resulting in very subtle wave movements – but sleepers still feel the undulations to some extent.
  • Waveless: Thick foam bolsters, baffles, and/or fiber padding completely contain the water chamber; as the name implies, sleepers do not experience any wave movements.

The table below illustrates some key differences between hardside and softside waterbeds.

How Do Waterbeds Feel?

As we mentioned above, waterbeds may be free-flow, semi-waveless, or waveless.

Free-flow waterbeds are ideal for people who essentially want to sleep on water. Some find the waves therapeutic and helpful for sleep onset. Because free-flow waterbeds are typically hardside models with thin covers, sleepers also feel the water very closely. However, free-flow waterbeds offer very poor motion isolation compared to other waterbed types, and all mattresses overall. Whenever someone gets into/out of bed or switches positions, their sleep partner will likely notice due to the waves generated by motion transfer. Generally speaking, free-flow waterbeds are not ideal for sleepers seeking a conventional mattress feel.

Semi-waveless waterbeds offer a good balance of the characteristic wave sensation of waterbeds and a standard mattress surface. Sleepers are somewhat close to the water, which can benefit those who enjoy that sensation. Semi-waveless waterbeds also isolate more motion than free-flow models, though sleepers may notice some slight undulations when their partner moves.

For all intents and purposes, waveless waterbeds feel like standard mattresses. Sleepers may sink deeply or slightly, depending on the comfort padding materials, but they will not experience any undulations; if they do, there may be a defect with the bed. That being said, waveless mattresses still use a fair amount of energy and are time-consuming to maintain. Sleepers who do not want to experience any waves may find that a conventional innerspring, memory foam, latex, hybrid, or airbed mattress is a more practical, low-maintenance option.

Other Important Considerations

In addition to the overall feel of the waterbed, shoppers should take the following factors into account:

  • Firmness: All waterbeds offer adjustable firmness because adding or removing water will affect how the mattress feels. Generally, filling the chamber to capacity will result in the firmest setting. Removing some water will soften the waterbed to an extent; however, underfilling will also result in a firmer feel.
  • Temperature control: Hardside waterbeds come with high-watt heaters that are very effective at raising the water to a comfortable temperature. Softside waterbeds, on the other hand, have low-watt heaters; they may not raise the water temperature as quickly or effectively. When the heater isn’t used, waterbeds tend to sleep cool – too cool, for many.
  • Sex: Hardside, free-flow waterbeds are the most responsive waterbed types. However, many couples find that the undulations interfere with sex. Semi-waveless and waveless waterbeds do not produce waves at the same level, but they are not as responsive either. Many couples liken semi-waveless and waveless waterbeds to memory foam mattresses, which lack responsiveness and may lead to uncomfortable sinkage during sex.
  • Odor potential: Hardside waterbeds have the highest odor potential, since vinyl is associated with strong initial off-gassing, and smells tend to linger for a long time. Softside waterbeds emit less odor, but owners may notice some initial off-gassing.
  • Noise: Waterbed heaters can produce some noise, but it is often a gentle whirring that some sleepers equate to white noise, which can help them fall asleep. Additionally, the water may slosh loudly if the chamber is not filled to capacity or near-capacity.
  • Bedding: A waterbed may necessitate a new sheet set if the bed’s size differs from the owner’s previous mattress. Hardside waterbeds usually require new sheet sets due to their unique dimensions (unless the bed is a California King, which corresponds with other mattresses in this size).
  • Assembly: Waterbeds usually take time to properly assemble. Some waterbed sellers offer in-home assembly at an extra charge to assist customers.
  • Break-in: Other mattress types are made with foams, coils, and other components that require breaking in, allowing them to adapt to the sleeper’s body. This is not the case with waterbeds; most require a very minimal (if any) break-in period.
  • Maintenance and costs: Waterbeds with temperature control heaters can cause the owner’s utility bills to increase by a considerable margin. Waterbeds – particularly hardside models – can also be expensive to maintain because they are susceptible to leaks and malfunctions. Maintaining waterbeds can be a challenge, as well. In the next section, we’ll provide some tips for caring for a waterbed.

Maintaining a Waterbed

Waterbed Lifespan and Warranty Considerations

If properly maintained, waterbeds can perform for seven years or longer. This gives them comparable lifespans to more durable mattress types, such as latex, hybrid, and airbed models. However, waterbeds are uniquely vulnerable to certain issues – such as water leaks and heater malfunctions – that can shorten their lifespan by a considerable margin.

Hardside waterbeds are considered the least durable because there is less padding and material to protect the water chamber. Any sharp object can cause a puncture; pet claws are especially problematic, meaning cats and dogs should never be allowed onto a hardside waterbed. Softside models are more durable overall. However, leaks can be harder to address if they develop due to their thick frames.

Because they are heavy and difficult to ship and assemble, most waterbed manufacturers do not offer a sleep trial of any kind. Instead, most brands offer longer-than-average warranties – typically 15 to 20 years minimum. Common defects covered under a waterbed warranty include splits or tears at the seams that cause leaks, and issues with waterbed zippers. Softside waterbeds with foam comfort layers may also warrant against excessive sagging or indentations, much like the warranties for standard mattresses.

Because waterbed warranties are longer, shoppers should pay close attention to the nonprorated vs. prorated schedule. During the nonprorated period, waterbed owners pay nothing for repairs or replacements if a defect develops except for shipping and handling charges. However, once the prorated phase kicks in owners must pay a certain percentage of the original product price. This percentage often increases with each year of ownership.

For instance, let’s say a $1,000 waterbed is covered under a 20-year warranty with 10 years of nonprorated coverage. In year 11, when prorated coverage kicks in, the owner must pay 5% of the original price for each year of ownership to replace the mattress; because it’s year 11, this percentage is 55%, or $550. In year 12, it will increase to 60%, or $600. As a result, prorated warranties can lead to extra owner costs down the road.

Another factor to consider is separate warranties for specific components. Commonly, the waterbed cover will be covered separately – for only one to two years, in some cases. Heaters may also be covered under separate warranties. If a defect does not develop with these components during their individual warranty period, then the overall waterbed warranty will not cover the issues.

Important Questions for Waterbed Shoppers

  • How much do you want to spend on a waterbed? Hardside waterbeds are generally much cheaper than softside models. By the same token, free-flow waterbeds tend to be less expensive than semi-waveless and waveless models.
  • Do you enjoy wave sensations? If yes, then a free-flow waterbed should be your ideal choice. These beds offer semi-intense to intense waves and close contact with the water. If no, then a waveless waterbed will be suitable. Those who like some waves may want to opt for a semi-waveless waterbed.
  • What bed size do you prefer? Both hardside and softside waterbeds are available in limited sizes compared to other mattress types, though softside sizes offer more options. Keep in mind that hardside waterbeds usually require new sheet sets, whereas softside models do not.
  • Do you experience back pain? Waterbeds with lumbar support are much better for sleepers with back pain. Those that do not have supportive components may exacerbate discomfort.
  • Do you sleep with a partner? If you share your bed with someone and you tend to wake up due to motion transfer, then a semi-waveless or waveless waterbed will probably be the best option. Free-flow waterbeds do not isolate very much motion, leading to frequent sleep disruptions.
  • What are your bedroom dimensions? Hardside waterbeds take up much more room than softside beds; regardless of which type you’d like to purchase, be sure to measure your room to ensure the bed will fit.
  • What’s your ideal sleep temperature? If you like a little warmth while you sleep, a hardside bed with a high-watt heater will be the best option; these beds heat the water quickly and effectively, though they use a fair amount of power. If you prefer to sleep cool, then a softside waterbed with a slower low-watt heater may be sufficient. If you like to sleep exceptionally cold, then you may not need the heater at all.
  • Are you sensitive to smell? Waterbeds tend to produce more off-gassing odor than other mattresses. This is especially true for hardside waterbeds with vinyl covers. Waterbed smells may be excessively strong and persist for longer periods of time.
  • Do you have an outside faucets? If no, you may want to reconsider getting a waterbed. Draining a water chamber is much easier with outside faucets and lowers the risk of damaging indoor spills.
