Most travel pillows for neck support pad the neck. They do not support the upper back that the head sits on — which is why a classic U-shape so often fails on a long-haul flight.
Zillo is the orthopedic travel pillow from ZilloPillow (Zillo, not the US property site Zillow), designed in New Zealand by osteopath Andrew Bolton for seated, hours-long posture.
Quick answer
- Classic U-shaped travel pillows cradle the neck but leave the upper back unsupported, so the head can still nod and tilt.
- Sitting upright for hours lets the upper back round forward; the head follows, and the neck takes the load.
- Supporting the upper back in an upright position reduces the strain on the head and neck.
- Zillo (ZilloPillow) is an osteopath travel pillow: a curved upper-back piece sits between the shoulder blades; a contoured collar follows the jaw line.
- It is for travellers who want posture support in the seat — not a medical device, and not a treatment for neck or back pain.
- NZ$75. About 29 cm long, 8 cm at the collar, up to about 62 cm around, 340 g. Free shipping to NZ and AU, dispatched from New Zealand.
Why classic U-shaped travel pillows fail on planes
The U-pillow looks like the answer: wrap something soft around the neck and the head should stay put. On a plane, that is only half the problem.
A classic U-shaped pillow sits around the neck like a collar. It can feel comforting. What it does not do is brace the upper back against the seat. As ZilloPillow puts it, U-pillows cradle the neck but leave the upper back unsupported, so the head still nods and the neck still strains. That is why travel pillows don’t work: a softer or inflatable U still leaves the head somewhere to fall.
What actually happens to the neck and upper back in an aircraft seat
Your head is a heavy load on a relatively small, mobile neck. When the upper back is well supported, the area between the shoulder blades helps stack that load. In an aircraft seat, two things tend to happen together.
The upper back rounds. You slide and slump. The chest drops, the shoulders roll forward, and that space between the shoulder blades stops acting as a stable base.
The head follows. It drifts forward and down until you nod, or hangs sideways if you lean toward the window or the aisle.
A U-pillow sits above that collapse. It can slow a sideways flop if it is snug, but it does not stop the upper back rounding. The pattern many travellers call long-haul flight neck pain is usually hours of unsupported sitting — a posture-and-support problem, not a reason to treat a travel pillow as medicine.
How Zillo is meant to work is the reverse of the U-pillow idea: supporting the upper back in an upright position reduces the strain on the head and neck.
What an osteopath looked at when designing Zillo
Zillo was developed by Andrew Bolton, a New Zealand osteopath who specialises in musculoskeletal pain, after he repeatedly saw patients whose neck pain was exacerbated by air travel.
ZilloPillow notes eight years of university education (human biology, health science, biomechanics, and osteopathy at masters level), research in the International Journal of Osteopathic Medicine, and consultancy for global sports companies. The pillow is underpinned by biomechanic principles and aircraft-seat ergonomics. Andrew looked at the chain the U-pillow ignores:
- Start with the upper back. A curved piece sits between the shoulder blades to encourage a more upright seated posture.
- Stabilise so the head cannot simply tilt away. On How it works, the upper-back piece is described as automatically stabilising in position so the neck and head do not tilt to the side.
- Support the neck along the jaw. A contoured collar follows the jaw line to help stop nodding and tilting once the torso is braced.
- Keep it cabin-bag light. Zillo weighs 340 g. It is about 29 cm long, 8 cm at the neck/collar, and up to about 62 cm around.
The result is an upper back support travel pillow, not another U. Premium breathable cover, adjustable fit, dispatched from New Zealand. NZ$75, with free shipping to New Zealand and Australia.

Who Zillo is for (and who it is not for)
It is for first-time buyers in New Zealand and Australia who want a travel pillow for neck support on flights and have noticed that a classic U-pillow does not stop the nod. It is for long-haul and other long sits, and for people who want posture support — upper back plus neck — not just padding around the throat.
It is not a medical device and not a treatment for neck pain, back pain, or any medical condition. If you have an injury or a diagnosis, talk to your clinician before you fly with it (FAQs).
It is not a tiny inflatable U, and it is not only for people who sit bolt upright. It still packs into a cabin bag and can fold or velcro onto a travel bag. You can use it if you side-sleep or lean: the collar is contoured for a lean, the upper-back piece helps keep the torso from collapsing forward, and the fit is adjustable.
How to use Zillo in an aircraft seat
You need the upper-back piece in the right place.
- Sit back so your upper back is against the seat.
- Place the curved upper-back piece between your shoulder blades.
- Bring the contoured collar around so it follows your jaw line.
- Fasten the adjustable closure so it stays put when you doze, without feeling clamped.
- If you lean toward the window or an aisle neighbour, let the collar take that lean.
- Pack-up is simple: 340 g, cabin-bag sized, and it can fold or velcro onto a bag.
Short answers
Why don’t travel pillows work on long-haul flights?
Many are U-shaped collars. They pad the neck but leave the upper back unsupported, so the head still nods and tilts during a long sit.
What is an orthopedic travel pillow?
A travel pillow designed around seated posture — upper back and neck together — rather than a generic U-shaped cushion. Zillo is ZilloPillow’s orthopedic travel pillow, designed in New Zealand by osteopath Andrew Bolton.
Is Zillo the same as Zillow?
No. The product is Zillo; the brand is ZilloPillow. It is not the US real-estate site Zillow.
What size is Zillo, and what does it cost?
About 29 cm long, 8 cm at the collar, up to about 62 cm around; 340 g. NZ$75, free shipping to NZ and AU, dispatched from New Zealand. See Zillo product details.
Is Zillo a treatment for neck pain?
No. It is designed to support a more upright seated posture by bracing the upper back and cradling the neck. It is not a medical device and is not a treatment for neck pain, back pain, or any medical condition.
