Born from a dream to bring high quality, satisfying sleep to people, Dr. Casey D'Arcy began exploring the inception of One Sheep. With nearly a decade spent studying spinal biomechanics, she was poised to architect a pillow that would actually conform to the cervical curve. Motivated by passion and the drive to help others, Casey believes the quality of one’s sleeping hours is an invaluable component to living a happy and healthy life. One Sheep is dedicated to developing thoughtfully engineered products to ensure a more meaningful sleep experience is achieved.

Hi! I’m Casey, founder of OneSheep. I care a lot about sleep—not just “eyes closed, lying in bed” sleep, but deeply restorative, wake-up-a-new-person sleep. I also care a lot about the human spine.

During my eight years in private practice, nearly everyone I met asked me what pillow I recommended. And honestly? I didn’t have a good answer—because most pillows out there seemed to do more harm than good. In fact, I often told my patients to remove their pillows entirely to help with pain. It was my go-to answer, but even that had its downsides. Sure, it helped eliminate the 5” anterior head posture, but it also left the head rotated all night.

I used to joke with my patients that I’d have to invent my own pillow someday. And after closing my practice in 2021, I finally went to the drawing board—literally. Three years (and an unrelenting obsession with getting it just right) later, that pillow is finally here.

My hope? To bring the essence of real sleep into your life. The kind where you fall asleep fast and wake up pain-free. Because when you sleep better, everything gets better.
