What Is a Water Pillow?
Unlike traditional pillows, water pillows conform to the shape of your head and neck, reducing pressure points and promoting proper spinal alignment, thus improving sleep quality and comfort. One of the most significant benefits is their customizable support. Adjusting the water level lets you achieve the perfect firmness to suit your preferences and sleep position.
How to Choose a Water Pillow
Finding the right pillow can make all the difference in how well you sleep, and water pillows offer a unique blend of support and comfort. Whether you’re looking for something to ease neck pain or want a pillow that adapts to your preferred level of firmness, there’s a water pillow out there that can cater to your needs. Here’s what to consider when choosing the best water pillow for a good night’s rest.
Prioritize Comfort and Support
Look for Adjustable Water Levels to Customize Firmness
By adding or removing water, you can experiment with different levels of comfort until you find the ideal setting. This level of personalization ensures that your pillow adapts to your body's specific requirements, enhancing your overall sleep experience and reducing discomfort.
Choose the Fill Material for the Support You Want
Being used in a water pillow means that the fill material is one of many factors determining the overall firmness of the pillow. For those with other preferences, down is considered one of the softest fillers, while buckwheat hulls are one of the firmest. Of course, these are generalizations, and there can be differences between pillows filled with the same material and those from different makers.
Choose a Pillow Designed for Your Preferred Sleep Position
Back Sleepers Should Opt for a Medium Pillow
The pillow's height is essential; it should be just enough to fill the space between your head and mattress. A pillow that is too high can strain your neck, while one that is too low may not provide adequate support. Consider pillows with a contoured shape designed to support the cervical spine.
For Side Sleepers, Thicker Is Better
Look for pillows with a slightly angled design or those that offer additional support for the shoulder area. This can help alleviate pressure points and improve sleep quality.
Look for a Thinner Pillow if You Sleep on Your Stomach
Evaluate Durability and Longevity
Investing in a quality water pillow is essential for long-term comfort and satisfaction. While water pillows offer many benefits, durability should be a key consideration to ensure your investment lasts.
Look For High-Quality, Durable Materials That Will Stand Up to Nightly Use
Look for thick, reinforced seams to prevent leaks and ensure the chamber can withstand the pressures of nightly use. Additionally, the chamber should be flexible enough to allow for even water distribution and conform to your head and neck without compromising its structural integrity. Avoid low-quality PVC materials that are prone to leaks and deterioration.
Look For a Warranty for Added Peace of Mind
Look for Hypoallergic and Breathable Materials to Enhance Hygiene
A breathable water pillow is essential for maintaining a cool, dry, hygienic sleep environment. Opt for pillows with materials that allow air to circulate freely, preventing the accumulation of heat and humidity, which can contribute to an environment conducive to bacteria. A breathable pillow also enhances comfort by preventing clamminess and stickiness during sleep.
Prioritize Machine-Washable Pillow Covers for Easy Cleaning
A removable, machine-washable cover makes it easy to keep your pillow fresh and free from allergens, dust mites, and bacteria. Look for pillow covers made from soft and durable materials that allow for frequent washing without compromising comfort. A zippered closure is often preferred for easy removal and reattachment of the cover.
Match Size to Your Space
Selecting a water pillow that complements your sleeping space is crucial for optimal comfort. Consider your bed's dimensions and the space you prefer between you and your partner. A pillow that takes up a disproportionate amount of space can crowd your sleeping area (especially if you don't utilize the extra space while sleeping).
At the same time, one that is too small may not provide adequate support or allow enough movement while sleeping. Standard pillow sizes tend to be approximately 28x20 inches, but some manufacturers offer options to cater to specific needs by providing specialty sizes. Active sleepers in larger beds may prefer a larger pillow.

A Brief Background of Water Pillows
Water pillows are a relatively new innovation, with the original patent being granted in 1975 to Yuuichi Nakata (Water pillow (freepatentsonline.com)). The patent for the most common version of the water pillow was granted in 1990 to Maurice Bard (Water pillow (freepatentsonline.com)). Bard founded Mediflow in 1994 to manufacture his new pillow (Mediflow's Water Pillow: Clinically Proven to Reduce Pain and Improve Sleep (yahoo.com)).
Mediflow is one of, if not the biggest, brands in this segment, likely because it holds the patent for the current design. As such, its products are heavily represented on our product list. mybest has no affiliation with the brands or products presented.
Consider the Pillow’s Shape to Fit Your Sleep Style
Some individuals may prefer specialty-shaped pillows, such as wedges, which elevate, and ergonomic pillows, which cradle. Both provide additional support for the head and neck. When choosing a pillow shape, consider your preferred sleep position and any specific comfort needs you may have. Experimenting with different shapes can help you find the perfect fit.
