Diagram of a side sleeper seen from behind: on a flat pillow the head drops below the line of the spine; on the butterfly-shaped pillow it stays level. off level

It might not be your age. It might be your pillow.

Why flat pillows leave side sleepers' necks bent all night, and the butterfly pillow built to fill the gap.

Your shoulder makes a gap.

Lie on your side and your shoulder lifts your head off the mattress. A flat pillow can't fill that space, so your head tips down and your neck stays bent for hours.

So you fold it in half.

Folded, it's too high and your head tilts up. Flat, it's too low. Either way, by morning it has squashed back down.

A shape made for the gap.

Derila Ergo is memory foam cut in a butterfly shape: raised where your neck needs filling, lower where your head rests. Your head stays in line with your spine.

Wake up without the 2 a.m. pillow fight.

No folding, no stacking, no second pillow. One shape that stays put from lights out to alarm.

How do you sleep?

Pick the way you usually wake up. We'll tell you straight whether this pillow fits.

Side sleepers: this is who it's built for.

Your shoulder sets the height. The raised outer edge fills the space between your ear and the mattress, so your head stays level instead of tipping down.

Back sleepers: use the middle.

The centre dips to cradle the back of your head and the curved front edge sits under your neck. No stack of pillows pushing your chin to your chest.

Switchers: roll without rearranging.

The butterfly cutouts give your arms somewhere to go, so you can turn from your back to your side without punching the pillow back into shape.

Stomach sleepers: honestly, probably not.

Face down, almost any raised pillow twists your neck to one side. A very thin pillow, or none at all, usually works better. We'd rather tell you now.

What you're actually getting.

A hand pressing into the light blue memory foam pillow, leaving a slow imprint

Memory foam that holds its shape.

It sinks slowly under your head and comes back once you lift it. It won't go flat by the end of the night the way a fiber pillow does.

Wings for your arms.

The cutouts on each side make room for an arm under the pillow, the way many side sleepers already lie.

Firm, not fluffy.

If you love sinking into a soft, cloud-like pillow, this will feel different. Most people need a few nights to settle in.

Straight answers.

Is this the official store?

No. The Rested Home is an independent guide. The pillow is sold on its maker's official store, and we may earn a commission if you buy through our links. It doesn't change your price.

Will it fix my neck or my snoring?

It's a pillow, not a medical device, and we won't promise it treats anything. If you have ongoing neck pain, numbness or loud snoring, see a doctor. What it does is keep your head at a steadier height while you sleep.

How long does it take to get used to?

A new shape usually feels odd for the first few nights. Give it about a week before you decide.

What does it cost?

It depends on the pack: bigger packs bring the price per pillow down. A shipping charge is added at checkout, and you see the full total before you pay.

What if it isn't for me?

Orders are covered by the seller's money-back guarantee. The window and how to return are shown on the order page.
