Derila is one of the more heavily-advertised cervical pillow brands, and its Standard butterfly pillow has a large review base of 6,490 ratings — but at 3.4★, it also has the most mixed feedback of any pillow in our comparison. We’re including it because the review volume is genuinely useful, and being upfront about the mixed results is more useful to you than pretending it’s uniformly loved.

What it’s like to sleep on

Derila ships vacuum-packed and takes several hours to expand into its full butterfly shape — several reviewers were initially alarmed that it looked misshapen straight out of the bag before it settled into the pictured shape over 4–5 hours. When it works, reviewers describe genuinely better sleep and reduced snoring. When it doesn’t, the complaints are specific and consistent: the pillow runs noticeably smaller than a standard pillow (several reviewers compare it to a kids’ pillow), standard pillowcases don’t fit it, and a handful received units with visible ridges or an uneven, defective shape.

The rating breakdown tells the story: 40% five-star reviews against 22% one-star, which is a much wider spread than any other pillow in this comparison. Reviewers who found it a good fit were genuinely enthusiastic; reviewers who found it too small or misshapen were equally vocal. It’s worth reading the size dimensions carefully before buying rather than assuming it’s a standard pillow size.

Large review base gives a genuine sample size to judge it by
Reviewers who found the fit right report real improvements in sleep and snoring

Cons

The most mixed rating of any pillow in our comparison — 22% one-star reviews

Who it’s best for

Worth considering only if you’ve checked the exact dimensions against your expectations and are comfortable with a wider-than-usual spread of outcomes — the brand recognition and review volume are real, but so is the inconsistency. Several of the other pillows in this comparison have a narrower, more predictable spread of reviews.
