Best Seat Cushions in Australia (2026)

A good seat cushion takes pressure off your tailbone and hips and can make a hard office chair or car seat far more comfortable for long sitting. The right shape depends on how you sit and why you need it: U-shaped cutouts relieve tailbone pressure, gel designs run cooler, and wedges tilt the pelvis forward. We compared the top-rated seat cushions available on Amazon Australia.

What to look for in a seat cushion

Shape. A U-shaped or butterfly cutout reduces pressure on the tailbone. A wedge tilts the pelvis, and a flat contoured pad spreads weight across the thighs. Choose the shape that matches where your discomfort is.

Memory foam or gel. Memory foam moulds to your shape and gives the most contouring but can feel warm. Gel and honeycomb designs stay cooler and bouncier but contour less. Gel-infused foam tries to combine both.

Size and thickness. Most cushions are around 18 inches wide. Wider seats need larger models, while thinner cushions suit chairs where you do not want to raise your seat height much. Thicker pads of around 3 inches cushion more deeply.

Cover and grip. A removable washable cover and a non-slip base are worth having so the cushion stays put and can be cleaned. A carry handle helps if you move the cushion between a desk and the car.

More individual reviews

Which one should you buy?

If you want a dependable all-rounder, start with the Sleepavo or FORTEM. If you run hot, look at the gel options (OMCOZY, KYSMOTIC or the gel-infused Everlasting Comfort). Large sitters or wide seats suit the KYSMOTIC. The very high-priced cushions have the biggest review bases, but cheaper cushions rate about as well. A cushion can make sitting more comfortable but it is not a medical treatment, so see a health professional if you have ongoing tailbone or back pain.

Frequently asked questions

What types of seat cushion are there?

The main types are gel, memory foam and honeycomb gel cushions. Many also have a cut-out at the back for the tailbone.

Do I need a tailbone cut-out?

Some people like a cut-out because it keeps pressure off the tailbone, while others prefer a solid cushion. It comes down to personal comfort.

Will it fit my office chair?

Check the cushion size against your seat, and look for a non-slip base and a strap if you want it to stay put. Dimensions are on each product page.

Gel or memory foam: which is better?

Memory foam moulds to you and gel tends to stay cooler. Many cushions combine the two.

How do I clean a seat cushion?

Many have a removable, washable cover. Follow the care instructions on the product.
