Best Lumbar Support Cushions in Australia (2026)

A lumbar support cushion fills the gap between your lower back and the chair, helping you keep the natural inward curve of your spine when you sit for long periods. It is one of the cheapest and simplest ways to make an office chair or car seat more supportive. We compared the top-rated lumbar cushions, pillows and rolls available on Amazon Australia, including memory foam, gel and inflatable designs.

What to look for in a lumbar cushion

Fill and firmness. Memory foam is the most common and moulds slowly to your back. Gel layers add cooling, while inflatable pillows let you adjust firmness but do not hold a fixed contour. Firmer foam generally holds your posture better over a long day.

Size and shape. A lumbar cushion should sit in the curve of your lower back, not behind your shoulders. Wide cushions cover more of the back, narrow ones suit small or sports-style seats, and a wedge shape is common in car-focused models. Measure your backrest before buying.

Straps. Elastic or buckled straps keep the cushion from sliding down the chair. Check that the strap length suits your chair, especially on wide or mesh-backed designs.

Cover and cleaning. A removable, machine-washable cover matters for something that sits against your back all day. Mesh covers are cooler, while smooth fabric is easier to wipe.

Which one should you buy?

If you work at a desk, start with the FORTEM for value or the Samsonite for the most proven option. If you travel a lot or want something that packs small, the Therm-a-Rest or SmartTravel inflatable are easier to carry. For the car, the BYMECOST is built around driver seats. A cushion can make sitting more comfortable but it is not a medical treatment, so see a health professional if you have ongoing or severe back pain.

Frequently asked questions

Where should a lumbar cushion go?

Place it in the small of your back, where your lower back curves in, and adjust the height until it feels comfortable.

Can I use one in the car?

Yes, many come with a strap for car seats. Make sure it does not interfere with how your seatbelt fits or with your driving position.

How thick or firm should it be?

That is personal. Thicker and firmer cushions give more support but may push you forward on a shallow seat, so check the dimensions and buyer comments.

Will a lumbar cushion fix back pain?

It can make sitting more comfortable, but it is not a treatment. If you have ongoing pain, speak to a GP or physiotherapist.

Can I use one with a seat cushion?

Yes, many people use both. Try them together to make sure you are still sitting comfortably with your feet flat on the floor.
