The Water Pillow by Mediflow

Wake up without the stiff neck.

Mediflow water pillows support your neck with a water base you fill yourself. Soft, medium or firm, your call.

Shop pillows How it works

Most pillows lose their shape before morning.

Foam and fiber compress under the weight of your head, so your neck spends hours out of line.

Water does not compress. The support you set at bedtime is still there when you wake up.

Water underneath. Comfort on top.

Every Mediflow pillow is built the same way, whichever comfort layer you choose.

  1. The comfort layer

    Memory foam, cooling gel foam, down, down alternative or fiber. Pick the feel you like against your cheek.

  2. The sealed water pouch

    Fully sealed and insulated, it sits under the comfort layer. The water shifts as you move and reshapes around your head and neck.

  3. Your fill level

    Add water for more height and firmness, or pour some out for less. Change it any night you like.

Fill guide

Find your starting fill.

Mediflow suggests about 2 liters for soft, 3 for medium and 4 to 5 for firm. Start here, then fine-tune over a few nights.

Suggested starting fill

3 to 4 L

Side sleeping leaves the widest gap between your shoulder and head, so most side sleepers want more height.

The research

In a Johns Hopkins study of people with chronic neck pain, a water-based pillow was linked to less morning pain and better sleep than their usual pillow.

Lavin, Pappagallo and Kuhlemeier, “Cervical pain: a comparison of three pillows,” Archives of Physical Medicine and Rehabilitation, 1997. Results vary from person to person, and a pillow is not a treatment for any medical condition.

Read every answer
How much water should I add?

Mediflow suggests about 2 liters (2 quarts) for soft support, 3 for medium and 4 to 5 for firm. Most people start around 3 liters and adjust over a few nights until the height feels right.

What is the difference between Original and Elite?

Both use the same adjustable water base. Elite pillows add a 100% cotton, 300 thread count shell, durable corded edges and extra-ventilated foams. The Elite Memory Foam pillow also has a zip-off case for easy washing.

Will the water feel cold or sloshy?

The pouch is insulated and sits beneath the comfort layer, so you feel the foam, down or fiber against your face rather than the water itself.

What pillowcase fits?

Both sizes fit standard and queen pillowcases. Foam and down pillows measure 18 x 26 inches. Fiber and down-alternative pillows measure 20 x 28 inches.

Can I return a pillow?

Unopened pillows in their original packaging can be returned within 30 days of delivery. For hygiene reasons we cannot accept pillows that have been opened or filled with water, unless they arrive damaged or defective. See the returns policy for details.
