Cooling · Side-sleeper · Cervical
If you sleep on your side, a firmer pillow was never the fix. Quill is shaped to cradle your neck and free the arm you're lying on, so you stop waking at 3 a.m. shaking it back to life.
Quill started with a simple truth: side sleepers were never the problem — their pillow was. So we engineered a butterfly-shaped cervical pillow that cradles the neck and frees the arm you're lying on, wrapped in breathable ice-silk that stays cool all night. This isn't just a pillow. It's the end of the 3 a.m. dead arm.
It was never about a firmer pillow, it was the shape. Quill makes room for the arm you're lying on and keeps your neck neutral, so you wake up and notice what's missing: no ache, no stiffness, no 3 a.m. arm‑shake.
You didn't imagine the numb arm, the kinked neck, or the 3 a.m. wake-ups. Sleep researchers have spent decades documenting exactly what happens to a side sleeper on the wrong pillow, and what changes when the shape finally fits. Quill was built around those findings, not around more foam.
Of adult sleep time is spent on the side, the position most pillows are not designed for.
Adults regularly wake with neck pain or stiffness that research links directly to pillow type and height.
Trials comparing pillow designs found neck-support shapes outperformed flat and firmer pillows for waking pain.
Raised sleep-surface temperature measurably increases night waking and cuts deep, restorative sleep.
Findings summarised from published sleep-posture and thermal-environment research, including Gordon & Grimmer-Somers (Physiotherapy Canada, 2011), Persson & Moritz (J Manipulative Physiol Ther, 1998), Jeon et al. (Tohoku J Exp Med, 2014) and Okamoto-Mizuno & Mizuno (J Physiological Anthropology, 2012).
Sleep on it, or get your money back.
Over three months to sleep on it properly. Give it the first few nights to adjust, since your neck has been compensating for a long time. If you're still waking up stiff, sore, or shaking your arm back to life, send it back for a complete refund. No questions, no restocking fee, no keeping one more pillow you don't use.
Real side sleepers, real first nights. Watch what changed.
Before You Decide
You've bought pillows before. Here's what's different, and what happens if it isn't.
No, and that's the whole point. Most cervical pillows try to fix side sleeping with more firmness, which is why they feel like a shoebox. Quill fixes it with shape instead. The butterfly cutout creates a channel for your arm and shoulder, so the foam doesn't need to be rigid to keep your neck neutral. It gives where your head sits and holds where your neck needs it.
This is the complaint we designed around. The cover is a breathable ice-silk that stays cool to the touch and moves heat away instead of trapping it, and the foam is ventilated rather than solid. Practically: no flipping it over at 2 a.m. hunting for the cold side.
Cheap contour pillows copy the silhouette without the geometry. Wrong loft, wrong cutout depth, and low-density foam that flattens within weeks, which puts your neck right back where it started. Quill holds its shape night after night, and comes with a 100-night guarantee, so you're not gambling. If it doesn't work, you're not out the money.
Usually that's a height mismatch. A pillow built for back sleepers puts a side sleeper's neck at an angle all night. Quill is shaped for side sleeping first, and every pillow ships with a removable 0.8" pad so you can drop the loft to match your shoulder width rather than being stuck with one height. Give it about five nights: if your neck has been compensating for years, the first couple can feel unfamiliar before it settles.
Fair question, and the only honest answer is that you shouldn't have to take our word for it. That's what the 100-night guarantee is for. Sleep on it for three months, and if you're still waking up stiff or shaking your arm out, send it back for a full refund. The risk sits with us, not you.
Then you send it back and get your money back, with no restocking fee and no interrogation. You've already got a closet full of pillows that didn't work. We're not asking you to add another one at your own expense.
