Short answer: the available evidence does not establish that the Derila butterfly pillow ends neck pain or adds 40 minutes of REM sleep. Derila markets its Ergo pillow for head and neck support, but the retrieved sources do not provide a controlled Derila-specific trial behind either outcome. A 2021 review of pillow research found some benefits for certain pain outcomes with rubber or spring pillows, but did not find a significant sleep-quality effect in people with chronic neck pain.
What is the Derila butterfly pillow?
Derila describes the Derila Ergo as a butterfly-shaped pillow intended to cradle the head and support the neck. That is the product’s design and marketing position, not proof that it treats neck pain or changes sleep stages. See Derila’s product page.
Does it end neck pain or add 40 minutes of REM sleep?
Those outcomes are not established by the sources available here. A Gadget Review article uses the claims in its headline and key takeaways, but the retrieved passage does not identify a Derila clinical trial or controlled measurement supporting them. Derila’s own research page says it could not find an independent, published clinical study testing the named product. That is the brand’s stated search result, not proof that no study exists anywhere.
In particular, the retrieved evidence does not supply a product-specific study measuring REM sleep or showing that Derila relieves neck pain. Customer ratings and testimonials, even when genuine, cannot establish an average clinical effect or a quantified change in sleep stages.

What does the broader pillow research show?
A 2021 systematic review and meta-analysis examined pillow designs and outcomes including neck pain, waking symptoms, disability, sleep quality, and alignment. Its authors included 35 articles; nine higher-quality studies involved 555 participants. They reported benefits favoring rubber pillows for neck pain, and rubber or spring pillows for some waking-pain and disability outcomes. These findings concern pillow categories, not Derila or butterfly-shaped pillows specifically.
For sleep quality among patients with chronic neck pain, the review reported no significant effect from pillow design (SMD 0.047, P=0.703). That outcome is not the same as a direct measurement of REM sleep, and it does not support a claim of 40 additional minutes. The authors’ abstract concludes that “The use of spring and rubber pillows are effective in reducing neck pain, waking symptoms, and disability and enhancing pillow satisfaction in patients with chronic neck pain.” The population and materials matter: the statement is about patients with chronic neck pain and spring or rubber pillows, not a Derila product trial.

Do the 4.5 stars and 11,000 reviews check out?
The headline’s “11K 4.5-Star Reviews” statistic is not verified by the retrieved sources: they do not establish which platform or date it refers to. Derila’s product page displayed a 4.5 rating, while its Trustpilot company page displayed 46,024 reviews and a 4.1 TrustScore when retrieved. These are different platform-specific measures, and review counts and scores can change. Neither rating verifies a pain-relief or REM-sleep claim.

A pillow is a fit choice, not a guaranteed treatment. The 2021 review notes that pillow shape and height may affect cervical alignment, but that does not show that one contour works for everyone. Compare options against practical criteria rather than relying on a product’s shape or headline claim:
