Derila Ergo for Side Sleepers

Side sleepers often need enough effective loft to fill the head-to-mattress gap created by the shoulder. Derila's fixed contour may suit some side sleepers, but shoulder width and mattress sink change the required height.

What the seller instructs

Derila's official guide includes a position-specific setup for side, back and stomach sleeping. That shows the intended use, but it does not prove the same 12 cm contour will fit every body and mattress.

What to check yourself

• Compare the published height with your current pillow.
• Consider mattress firmness and how far your body sinks.
• Pay attention to comfort rather than chasing a “perfect alignment” claim.
