Shop the Mattress Sale for a Better Night's Sleep

The right mattress comes down to how you sleep and who you share with. Start with size, from singles and doubles for solo sleepers and smaller rooms up to queen and king for couples and anyone who likes room to move. Then think about feel, since side sleepers, back sleepers and hot sleepers all want something slightly different. Measure your bedroom before you buy, and line your new mattress up with a bed frame to match.

Every Koala mattress is built around a Kloudcell® comfort layer, with zoned support that eases pressure on your shoulders and hips while keeping your spine aligned, and adjustable firmness on selected models so you can set it up the way you sleep. It's designed and tested by our Sydney R&D team, delivered free to your door, and backed by our 120 day trial and 10-year warranty. That means months to actually sleep on it before you decide, not five minutes in a showroom. With up to 25% off from Monday 10th August, it's the easy time to upgrade the thing you spend a third of your life on.

FAQ About the Mattress Sale

What's in the Afterpay Day Mattress Sale?

Mattresses in every size at up to 25% off, as part of Koala's wider Afterpay Day Sale. Discounts vary from product to product, so have a scroll through the collection above to see what's on offer.

When does the Mattress Sale run, and can I shop it in store?

It's on from Monday 17th August 2026 for a limited time, while stock lasts. The sale is mainly online at au.koala.com with free delivery to your door, and it also applies to in-person purchases at our Moore Park Showroom in Sydney.

What size mattress should I get?

Match it to who's sleeping and the room it's going in. Singles and doubles suit kids, solo sleepers and smaller rooms, while queens and kings give couples more space to spread out. Measure your bedroom first, then our mattress size guide breaks down every size and its dimensions.

Can I try a Koala mattress before I commit?

Yep. Every Koala mattress comes with our 120 day trial, so you can sleep on it at home for months rather than test it for a few minutes in store. If it's not right, get in touch and we'll sort a return, with free pickup on mattresses in most metro areas.

Are Koala mattresses firm or soft?

Koala mattresses are built with a Kloudcell® comfort layer and zoned support, with adjustable firmness on selected models so you can set it firmer or softer to suit how you sleep. The 120 day trial gives you plenty of time to get the feel right at home.
