Coccyx Cushions: What Are They and How Do You Use Them?
Sitting on a hard or unsupportive chair for hours is uncomfortable for most people. But for some, the discomfort centres specifically on the tailbone area, that small pointed bone right at the base of the spine that takes direct pressure every time you sit down.
A coccyx cushion is designed around that specific problem. It's not a complicated product, but there's a right and wrong way to use one, and knowing the difference is what makes it actually useful rather than just another thing sitting on your chair.
Here's everything you need to know.
What is a coccyx cushion?
A coccyx cushion is a seat cushion with a cut-out section at the rear. The cut-out is usually U-shaped or wedge-shaped, and its job is simple: to remove direct contact between the seat surface and the tailbone when you sit down.
On a standard flat cushion or chair seat, your tailbone takes pressure the whole time you're sitting. That pressure builds over long sessions and makes sitting uncomfortable, especially on hard chairs or in fixed positions for extended periods.
The cut-out design of a coccyx cushion suspends the tailbone in the open space rather than pressing it against a surface. The rest of the seat area still supports your weight through the sit bones on either side.
That's the core idea. Simple, but effective for the right person in the right situation.
What's the difference between a regular seat cushion and a coccyx cushion?
A regular seat cushion adds softness or structure across the whole seat. It helps with general sitting comfort but doesn't specifically address the tailbone area.
A coccyx cushion does both. It supports the seat area the same way a regular cushion does, but removes pressure from the specific spot where the tailbone sits.
| Feature | Regular Seat Cushion | Coccyx Cushion |
|---|---|---|
| Tailbone pressure | Same as chair | Reduced via cut-out |
| General seat comfort | Yes | Yes |
| Airflow (honeycomb gel) | Yes | Yes |
| Works on any chair | Yes | Yes |
| Car use | Yes | Yes |
| Best for | General desk comfort | Tailbone discomfort during sitting |
The Pain Free Aussies Honeycomb Gel Seat Cushion combines the open-cell honeycomb gel structure with a coccyx cut-out design. That means you get the airflow benefits of the gel alongside the tailbone relief of the cut-out, in one cushion. Currently available as a BOGO pack of two for $89.99 AUD with free shipping across Australia.
Who uses coccyx cushions?
More people than you'd think. Coccyx cushions aren't just for people recovering from a specific injury. They're a practical everyday comfort product for anyone who finds long-term sitting uncomfortable around the tailbone area.
They tend to suit:
- Desk workers who sit for 6 to 8 hours and notice discomfort building through the day
- Drivers who spend long hours behind the wheel, whether for work or long-distance travel
- Students in lecture theatres or hard university seating
- People who work from home on chairs that aren't designed for full working-day use
- Older adults who find hard seating increasingly uncomfortable over time
- Anyone returning to regular sitting after a period of reduced activity
It's a comfort product for everyday use. If you have any existing tailbone injury, spinal condition, or health concern affecting your sitting comfort, speak with your GP or physio before relying on a cushion as your primary approach.
How to use a coccyx cushion correctly
This is where most people go wrong. Placing the cushion incorrectly on the chair means the cut-out isn't doing its job.
Step 1: Position the cut-out at the back The U-shaped or wedge cut-out should face the rear of the chair, not the front. It needs to align with where your tailbone actually sits when you're in a normal seated position.
Step 2: Sit back fully into the chair Don't perch at the front edge of your seat. Sit back so your hips are against the backrest. This positions your tailbone directly over the cut-out rather than sitting behind it.
Step 3: Check the cushion isn't too far forward If the cushion is sitting too far toward the front of the chair, slide it back until the cut-out lines up with the base of your spine. You'll feel the difference immediately when it's right.
Step 4: Use it on a chair with back support A coccyx cushion works best paired with a chair that supports your lower back. Without back support, you tend to slouch forward, which shifts weight off the cut-out and back onto the tailbone anyway.
Step 5: Give it a few days Sitting in a new position feels unusual at first. Give it 3 to 4 days before deciding whether the position is right. Most people find the correct placement within the first week.
Why honeycomb gel works well for a coccyx cushion
Most coccyx cushions are made from memory foam. Memory foam softens under body heat and compresses over time, which means the support it offers on day one is different to what it offers after 6 months of daily use.
Honeycomb gel holds its structure better under regular pressure. The open-cell design distributes weight across the peaks of the grid rather than compressing into a flat surface. And the airflow through the open cells keeps the seat from warming up the way a solid foam cushion does, which matters a lot for long desk sessions in Australian conditions.
The Pain Free Aussies Honeycomb Gel Seat Cushion has a washable cover, a non-slip base to stop it migrating on the chair, and a 4.8-star rating from 56 Australian reviews. The BOGO pack gives you two cushions for $89.99, which works well for splitting between a home desk and a car seat.
Long hours of sitting don't have to mean a sore tailbone by mid-afternoon. A coccyx cushion is a simple, practical comfort upgrade for any chair. Get the placement right, pair it with decent back support, and most people notice the difference within a few days.

Frequently Asked Questions
What is a coccyx cushion used for?
A coccyx cushion is a seat cushion designed with a U-shaped or wedge cut-out at the rear. The cut-out is designed to remove direct contact between the seat surface and the tailbone when sitting. It is a home comfort product and is not designed to treat any medical condition.
How do you sit on a coccyx cushion correctly?
Position the cut-out at the rear of the chair so it aligns with where your tailbone sits. Sit back fully into the chair with your hips against the backrest so your tailbone is directly over the cut-out, not behind it. Pairing it with a chair that has lower back support gives the best result from the cushion's design.
Is a gel cushion better than memory foam for the tailbone?
Gel honeycomb and memory foam coccyx cushions are designed differently. Memory foam softens under body heat and compresses over time, which changes how it feels with daily use. A honeycomb gel cushion uses an open-cell structure designed to hold its shape under regular pressure and allow airflow through the seat, which reduces heat build-up during long sitting sessions.
Who should use a coccyx cushion?
A coccyx cushion is designed for anyone who finds long-term sitting uncomfortable around the tailbone area. It tends to suit desk workers, drivers, students, and people working from home on chairs not designed for full working-day use. If you have an existing tailbone injury, spinal condition, or any health concern affecting your sitting comfort, speak with your GP or physio before use.
