What Causes Tailbone Pain?

Tailbone pain, known clinically as coccydynia, is more common than many people realise, especially among older Australians and anyone who spends long hours seated. The good news is that the right cushion can make a genuine difference to your day.
Understanding what's behind your pain helps you choose the right type of cushion. The causes vary, but the solution is often the same: take direct pressure off the tailbone while you sit.
Common causes: fracture, bruising, arthritis, and prolonged sitting
The coccyx (tailbone) is the small triangular bone at the very base of your spine. It can become painful for several reasons:
- A fall or direct impact — landing hard on a firm surface is one of the most common causes
- Fracture or bruising — even a minor fracture takes weeks to heal, and sitting is uncomfortable throughout that time
- Degenerative joint changes — arthritis around the coccyx becomes more common with age
- Childbirth — the tailbone can be stressed or displaced during delivery
- Prolonged sitting on hard or poorly cushioned surfaces — this is where a good cushion does the most work
If your pain is severe, persistent, or came on after a fall, it's worth checking in with your GP before buying a cushion. For most people managing mild to moderate discomfort, a well-chosen coccyx cushion is a practical first step.

Why sitting makes it worse
When you sit on a flat surface, your body weight concentrates directly on your tailbone and the surrounding tissue. Even a soft chair provides little protection if there's no specific relief for the coccyx area. A purpose-designed cushion changes that entirely.
How a Coccyx Cushion Works

A coccyx cushion is specifically shaped to suspend your tailbone in the air while you sit, so it carries no weight at all. Once you understand the design, it's easy to see why it works so well.
The cut-out design and why it matters
Most coccyx cushions feature a U-shaped or horseshoe cut-out at the back of the cushion. When you sit down, your sitting bones (ischial tuberosities) carry your weight on the main cushion body, while your tailbone hangs free in the cut-out space.
This removes direct pressure entirely. It's not about making the seat softer — it's about making part of the seat disappear for the tailbone.
Many designs also include a gentle forward wedge angle (typically around 9 degrees). This encourages a more natural pelvic tilt, which takes stress off the lower back and lumbar discs at the same time.
Coccyx cushion vs standard pressure cushion: what's the difference?
A standard pressure-relief cushion, the kind used to prevent pressure sores, distributes weight evenly across a larger area. It reduces peak pressure across the whole seat. That's useful for people who are at risk of skin breakdown.
A coccyx cushion does something different: it removes pressure from one specific point. It's designed for pain relief at the tailbone, not whole-seat pressure redistribution.
Some people need both. If you're managing tailbone pain and you're also at risk of pressure injuries (for example, after a long hospital stay or with limited mobility), it's worth talking to your healthcare provider about which type suits your situation best.

Gel cushions vs foam cut-out cushions
You'll find two main material types:
- Memory foam with a cut-out — conforms to your shape, provides good support, and is usually more affordable. Most coccyx cushions fall into this category.
- Gel or gel-foam hybrid — gel adds a cooling, pressure-dispersing layer on top of the foam. Some gel cushions can relieve coccyx pain even without a cut-out, because the gel redistributes weight so effectively. Gel options tend to sit in the $80–$150 AUD range.
For most people managing mild to moderate tailbone pain, a quality foam cushion with a proper cut-out is the most practical starting point.
A note on donut/ring cushions
You may have seen round donut-shaped or ring cushions at pharmacies. These look like they'd relieve tailbone pressure, and for some people they do provide short-term comfort.
However, they are generally not recommended for pressure sore prevention or active tissue damage, because the ring design can restrict blood flow around the edges and create new pressure points. If you're managing a pressure injury as well as tailbone pain, a standard coccyx cut-out cushion or a clinical-grade pressure cushion is the better choice. A donut cushion is fine for occasional, temporary relief, but it's less suitable as an everyday seated solution.
What to Look For When Buying

Not all coccyx cushions are equal. Here's what to check before you buy.
Cut-out shape: U-shape, horseshoe, wedge
The depth and width of the cut-out matters. A deeper, wider cut-out provides more suspension and is better suited to significant tailbone pain. A shallower cut-out gives lighter relief and may be more comfortable if your discomfort is mild.
Wedge-shaped cushions tilt the pelvis forward without a cut-out. These are better for posture correction and lower back support than for direct coccyx pain relief. Make sure you're buying the right design for your specific need.
Foam density and material
Denser foam holds its shape longer and provides consistent support. Softer foam may feel comfortable at first but can compress too much over time, which reduces the effectiveness of the cut-out. Look for high-density memory foam or quality orthopaedic foam with a washable cover.
Non-slip base and portability
A non-slip base keeps the cushion in place on slippery chair surfaces, which is especially important on office chairs or smooth dining chairs. If you want to use your cushion in a car, at a desk, and at home, look for a portable design with a carry handle or a cover that zips off for washing.
Price range in Australia ($40–$150 AUD)
Coccyx cushions in Australia generally range from around $40 for a basic foam option up to $150 for a gel-foam hybrid or a medical-grade design. Most people will find a well-made foam cushion in the $60–$90 range covers their needs comfortably.
A word on price: spending a little more on a cushion with good foam density and a proper cut-out usually means better long-term support. A very low-cost option may compress and lose its shape within weeks.
Chemist Warehouse vs a proper medical cushion: when each is right
It's no surprise that "tailbone cushion chemist warehouse" is one of the most-searched terms for this product in Australia. Pharmacy options are convenient, reasonably priced, and fine for many people managing mild, occasional tailbone discomfort.
A pharmacy cushion is a good choice if:
- Your pain is mild and came on after a period of prolonged sitting
- You need temporary relief (for example, during post-injury recovery)
- You want something you can pick up over the counter quickly
A purpose-designed medical-grade coccyx cushion is worth considering if:
- You're managing chronic tailbone pain or coccydynia
- You sit for extended periods daily (office work, wheelchair use, long drives)
- You need NDIS or Home Care Package compatibility
- You've tried a pharmacy option and found it didn't provide enough relief
We stock foam, gel, and gel-foam coccyx cushions across a range of price points, all available with Australia-wide delivery. Browse our full coccyx cushion range to find the right fit for your situation.
Key takeaways:
- A coccyx cushion suspends the tailbone in a cut-out, removing pressure rather than softening the surface
- Memory foam cut-out cushions work well for most people; gel options add extra pressure distribution
- Donut/ring cushions are not ideal for pressure sore prevention or daily use
- Pharmacy cushions suit mild, occasional pain; medical-grade options are better for chronic or daily use
- Expect to spend $40–$150 AUD, with the $60–$90 range covering most needs
