What Is Derila?
The Derila Ergo Pillow is a butterfly-shaped, 13cm-tall memory-foam pillow with a central head cradle and raised side wings.
Its fixed height suits side and back sleepers well but is a poor match for stomach sleepers - worth knowing before you order.
A butterfly-shaped ergonomic memory-foam pillow
The Derila Ergo Pillow is a high-density memory-foam pillow measuring approximately 54 x 36 x 13 cm, built around a central head-cradle and raised side “wings.” It's designed to encourage natural spinal alignment, primarily for side and back sleepers dealing with morning neck stiffness.
See the full sleep-position fit guide before ordering — the fixed 13cm height is a genuinely important detail.
Two things worth knowing upfront
First, most buyers should expect a 3–7 night breaking-in period as the firmer support feels unfamiliar at first. Second, the pillow's height is specifically tuned for side and back sleeping — dedicated stomach sleepers commonly find it too tall.
Who it's designed for
Side and back sleepers, average to tall frames, dealing with morning neck or shoulder stiffness. Read next: how Derila works.
