Frequently Asked Questions

What makes the Tri-Core Water Pillow different from a regular pillow?

The Tri-Core Water Pillow combines ergonomic cervical support with a water-adjustable base. You can add or remove water to fine-tune the pillow’s feel - from firmer and more supportive to softer and more cushioned - while still benefiting from the Tri-Core’s contour design that supports proper neck alignment.

How do I adjust Tri-Core Water Pillow's water level for comfort?

Adjusting the water level is simple: fill the water pouch to your desired firmness and then zip the pillow closed. Less water creates a softer feel, while more water makes it firmer and more supportive. This lets you personalize your sleep experience night after night.

Will the water inside the Tri-Core Water Pillow stay in place when I move?

Yes, the Tri-Core Water Pillow's water chamber is designed to stay secure and minimize movement as you shift during sleep. You’ll enjoy stable support without sloshing or disruption, so the pillow stays comfortable throughout the night.

Can the Tri-Core Water Pillow help with neck pain or stiffness?

Many sleepers find that the Tri-Core Water Pillow helps relieve neck pain and tension by supporting the natural curve of the neck while sleeping. Proper alignment and personalized firmness can make a meaningful difference in comfort, especially for back and side sleepers.

How do I care for the Tri-Core Water Pillow?

Caring for the Tri-Core Water Pillow is simple and convenient. The water chamber is removable, making filling and maintenance easy, and features a recessed, threaded fill port with a secure screw-on cap to help prevent leaks - so you can rest easy knowing your pillow will stay dry. For laundering, just remove the water chamber and place the remainder of the pillow in the washing machine.

Why is this pillow being folded/ compressed?

We fold and compress this pillow as part of our commitment to reducing our carbon footprint. Compact packaging helps minimize the environmental impact of shipping while keeping your pillow protected during transit.

Although it may look different when first unpacked, the quality and integrity of the pillow are not affected. After removal from the packaging, it may take 5–7 days to fully regain its shape and performance. With a little patience, it will return to the supportive comfort it was designed to provide. Trust the process - it’s worth the wait!
