10 Best Waterbed Mattresses 2025 in the United States

The California King 90% Waveless Waterbed Mattress with Lumbar Support is designed to provide a comfortable sleeping experience, particularly for those who prefer the unique feel of a waterbed. One of its key strengths is the 8 Layer Mid-Body Support System, which offers solid lumbar support, making it a good choice for individuals who need extra back support. The 22 Mil Premium Aqua Marine Vinyl used for the cover enhances durability and water resistance, ensuring that the mattress is less prone to punctures or leaks.

In terms of size, it fits perfectly in a California King hardside waterbed frame, which is great for users looking for spacious sleeping arrangements. The inclusion of a fill and drain kit adds convenience, making setup and maintenance easier.

There are some considerations to keep in mind. While the waveless design significantly reduces motion transfer, it may still not offer the same level of stability as a traditional mattress. Additionally, depending on personal preferences, some users may find the firmness level less adjustable compared to other types of mattresses. It is also important to consider the heating system; while it doesn't mention a built-in heater, those who enjoy warmth may want to invest in a separate heating pad. The 20-year limited warranty provides a sense of security, but potential buyers should carefully read the terms to understand what is covered. This mattress is ideal for anyone looking for a spacious waterbed option with good back support, but it’s essential to weigh the benefits against individual comfort preferences.

The California King 72 x 84 Semi Waveless Waterbed Mattress is designed for those who prefer a traditional waterbed experience with moderate wave reduction.

This mattress is semi-waveless, meaning it has about 8-10 seconds of movement, which is suitable for users who enjoy a bit of the classic waterbed feel but with some motion control. With its size, it fits perfectly into Cal King hardside waterbed frames, offering ample space for sleepers. The reinforced corners add durability, ensuring the mattress holds up well over time.

Made from vinyl or polyvinyl chloride, the material quality is standard and designed to be soft and contouring, providing a comfortable sleep surface. A notable feature is the included 4oz bottle of Premium Clear Bottle Conditioner & Fill Kit, which helps maintain the mattress. However, the mattress only has one layer of fiber for wave reduction, which means it might not be the best choice for those looking for significant motion dampening. Additionally, the heating system is not included, so users will need to purchase one separately if desired. The hand-wash-only care instructions could be a bit inconvenient for some.

This product is particularly suitable for individuals who appreciate a bit of motion in their waterbed but still want some level of support and firmness.

The Free Flow WATERBED Mattress KIT (Queen 60x84 1FFS2) by INNOMAX is designed for those who prefer a traditional waterbed experience. One of the notable strengths is its comprehensive kit that includes a stand-up safety liner and a Blue Magic fill and drain kit with conditioner, making it easier to set up and maintain. The vinyl cover material is durable and should withstand regular use. The mattress measures 84 inches long by 60 inches wide, providing ample space for a queen-sized bed frame. At 10 inches thick, it offers a substantial level of comfort and support.

As a free-flow waterbed, it may not provide significant wave reduction, which can result in more motion transfer compared to other waterbed types. This could be a drawback for those who are sensitive to movement during sleep. The mattress is marketed as having possible motion isolation, yet the effectiveness of this feature is likely limited given the free-flow design. There's no mention of an included heating system, which is a common feature for waterbeds to provide consistent warmth. This might require an additional purchase of a compatible heater. This product is best suited for users who are familiar with and enjoy the unique feel of a traditional free-flow waterbed, and who don’t mind the potential for extra movement.
