If you just bought a contour pillow and the first night felt wrong, you’re not alone. Knowing how to use a contour pillow comes down to one thing most boxes don’t explain well: the two edges are two different heights, and you choose the edge for the position you sleep in. In comments under popular pillow videos, people say exactly this: “I just bought a cervical pillow and now I know why there’s low and high edges and when to use them.”
This is general guidance. Your pillow’s own label or instructions come first.
Why a contour pillow has a high side and a low side
When you lie on your side, your shoulder lifts your head, so the gap between your head and the mattress is large. When you lie on your back, that shoulder gap disappears and your head needs much less lift. The Sleep Foundation reflects this in its loft guidance: side sleepers generally prefer a high-loft pillow, above 5 inches (Sleep Foundation), while back sleepers usually do well with a mid-loft pillow between 3 and 5 inches thick (Sleep Foundation).
A contour pillow builds two heights into one shape. That is the whole point of the two edges.
How to use a contour pillow for side sleeping
Our rule of thumb: for side sleeping, put the higher edge under your neck, with your shoulder resting on the mattress just below the pillow. That fills the larger gap and keeps your head level with your spine.
One viewer described learning this from a demonstration: “I’ve used the low side under my neck whilst sleeping on my back but now understand why switching to the high side at the front is better for shoulder/side sleeping.”
Check it: lie on your side and ask someone to look from behind, or take a photo. Your nose, chin and breastbone should line up roughly with the middle of your body. If your head tilts up, try the lower edge; if it drops toward the mattress, the pillow may be too low for your shoulders.
Which side to use for back sleeping
Our rule of thumb: for back sleeping, use the lower edge under your neck. On your back, the higher edge can push your chin toward your chest. Your face should point straight up, not down at your feet.
The Sleep Foundation lists back and side sleeping as the best positions for people with neck pain, and suggests avoiding stomach sleeping (Sleep Foundation).
If you switch positions during the night
This is the hardest case for a fixed contour pillow, because one edge is under your neck when you roll over. Some people turn the pillow when they change position; others choose a shape built for switching. A buyer summed up the frustration: “I tend to move around a lot and cannot possibly keep my neck in that groove.”
If that’s you, look at our guide to the best pillow for side and back sleepers and the butterfly pillow, a shape designed around changing position.
Get the size right first
The edges only help if the pillow is the right overall height for your body. Some brands sell contour pillows in sizes. Tempur-Pedic, for its TEMPUR-Neck, says to place a ruler perpendicular to your neck, measure from the base of the neck to the outside edge of the shoulder, and choose the smaller size if you fall between two (Tempur-Pedic). Our pillow loft guide explains how to measure and how your mattress changes the height you need.
A common complaint goes the other way: “I’m a petite person and every neck pillow I buy is too high.” If both edges feel too tall, the pillow is probably the wrong size for you, not the wrong way round.
Give it time, then decide
A new shape can feel odd at first. One buyer wrote after the first night: “It was brutal…my neck this morning. I hope it’s just because my body has to get used to it.” Elviros, which makes contour pillows, recommends using its pillow for at least 30 nights to give your body time to adjust, within its 100-day return window (Elviros).
Return windows vary a lot between brands. Some don’t accept pillow returns at all, so check before you buy; our Melara Max vs TEMPUR-Neck comparison shows how different the rules can be.
When the pillow isn’t the problem
A pillow is a comfort product, not a treatment. If pain keeps coming back after you have fixed the edge, the height and your position, talk to a doctor or physical therapist. The Sleep Foundation advises seeing a health care provider promptly if neck pain comes with fever, headache, weakness or shortness of breath (Sleep Foundation).
How we put this guide together
We used the Sleep Foundation’s loft and sleep-position guidance, published information from Tempur-Pedic and Elviros, checked on November 10, 2026, and comments under popular pillow videos. We did not find an official industry rule on which edge to use, so the edge advice is our rule of thumb based on loft. Read how we review pillows.
