Things to Consider

A water pillow can seriously change your life. It can bring comfort and ease of pain, leaving you refreshed and even happier. To help you find the best water pillow, take a look at our buying guide so you know what to expect.

How does a water pillow work?

Water Pillow 1

A water pillow works because of the inner water pouch. There is also a filling material such as memory foam or polyester fill. You can add as much or as little water as you would like, depending on what type of firmness you desire.

When you lay down on a water pillow, the water pouch supports your entire head and neck. There are no pressure points and you don’t have to worry about fluffing your pillow during the night.

Advantages and disadvantages of a water pillow

A water pillow is a newer invention and is perfect for those who suffer from back pain, are recovering from surgery, or have chronic headaches. It gives unparalleled support and allows you to wake up feeling refreshed.

Unfortunately, water pillows tend to make a fair bit of noise at night. If you want a softer support, then less water will be used. This, however, increases the room for sloshing and it can take a few nights to get used to the sound.

Key features of a water pillow to consider

Before you purchase a water pillow, take a look at the possible features they can come with.

Pillow size

Water pillows are usually a standard 20 x 28 inches in size, which is a Queen size pillow. There are others that are smaller, such as the Mediflow Travel Size Water Pillow which measures 13 x 21 inches.

Filling material

Most water pillows, such as MODERNJOE’S Premium Water Base Pillow are filled with polyester fiber. Other more premium water pillows, such as the Mediflow Memory Foam Water Pillow, are made with memory foam. As is to be expected, memory foam water-based pillows have a higher price point.

Cover

A cover for a water pillow is very important because the insides aren’t machine washable. A cover should be soft for added comfort. The Mediflow Fiber Water Pillow is a nice product because it has a few options for covers. You can purchase a standard pillow and cover. You can also purchase a hypoallergenic cover.

Warranty

There are a few water-based pillows, such as the Mediflow Fiber Water Pillow, that come with a three-year warranty. Others, like the MODERNJOE’S Premium Water Base Pillow only have a one-year warranty. The travel-size Mediflow Travel Size Water Pillow does not list a warranty length.

It’s also nice if the company offers a 30-day trial period, which the Mediflow company does.

How to use a water pillow

Water Pillow 2

After purchase, your water pillow needs to be filled with water. This is the tricky part. You will want to play around with the amount of water used to determine the desired firmness. It is usually easier to fill a water pillow up than it is to empty the water.

FAQ

Can I adjust the firmness of my water pillow?

Yes, the beauty of a water pillow is that it can be adjusted. Less water means less firm. It just might take a bit of trial and error to find the right firmness.

Can a water pillow help with neck pain?

Yes, a water pillow can help with neck pain. The pillow works to better support your neck area, allowing the whole spine to be cradled in the right position.

Can a water pillow be washed in a washing machine?

Most water pillows will have removable covers that can be placed in the washing machine. The inner water pouch, however, is not machine washable.

What is the maximum amount of water usually allowed in a water pillow?

The maximum amount of water in a water pillow is 4 or 5 liters.

Does a water pillow keep you cool?

A water pillow can keep you cool. The material used alongside it, such as memory foam, will also keep you cool.

Does the water inside a water pillow make noise?

The less water there is in a water pillow, the more opportunity it has to slosh around and make a noise. It can take a bit getting used to, but usually after a few nights you get used to the noise.
