Derila Fit Guide

Quick Answer

Use the nose-to-chest test to check fit: your nose should align with the center of your chest in your sleep position.

The Derila suits side and back sleepers well; stomach sleepers should think twice given the fixed 13cm height.

The nose-to-chest test

Lying in your primary sleep position, your nose should roughly align with the center of your chest. If it tilts upward, your pillow is too high; if it tilts downward, too low. This is the quickest sanity check once your Derila arrives.

Match loft to your frame

Broad-shouldered side sleepers generally need a higher loft (roughly 4–6 inches) to keep the head from tilting toward the mattress. Smaller or narrower frames often find a mid-loft more comfortable. At 5.1 inches, the Derila sits toward the higher end of this range.

Consider your mattress

A soft mattress lets your body sink deeper, requiring less pillow height. A firmer mattress keeps you higher on top, requiring a taller, more structured pillow like the Derila to properly bridge the distance to your shoulder.

Position-by-position breakdown

Best fit

Side Sleepers

The side wings fill the shoulder-to-ear gap directly — this is the position the design is most specifically built for.

Good fit

Back Sleepers

The central cradle supports the neck curve well, helping maintain a neutral spine position.

Likely poor fit

Stomach Sleepers

The fixed 13cm height can force the neck into an unnatural upward arch, potentially causing strain rather than relief.

A practical note: if you regularly switch between back/side sleeping and stomach sleeping through the night, weigh this honestly before ordering — the pillow's strengths are real for its intended positions, but it is not a universal fit. See our full article on this mismatch.
