Koala Mattress Review 2026
One of Australia’s best-known mattresses. 4.8 from 1,500+ ProductReview owners, B-Corp certified, 4-hour metro delivery, flippable firmness, and that famous wine glass test. But does popularity equal quality? Here’s our honest take.
Koala is Australia’s best-selling mattress for a reason — it does most things well without being the best at any single thing. The flippable Kloudcell comfort layer gives you medium-firm or firm options, the “zero disturbance” foam genuinely isolates partner movement, and the 4-hour metro delivery is the fastest in Australia. Add B-Corp certification, 1% for the Planet membership, and $4.9M+ donated to koala conservation, and you have a brand that’s easy to support. The trade-offs: it’s all-foam (no springs), edge support is average, it’s not the coolest sleeper, and at $999 for a Queen it’s not the cheapest option. But as a reliable, well-rounded all-rounder that’s easy to buy and easy to live with, Koala earned its popularity.
SKIP IF: You want the cheapest option, need springs, sleep very hot, or weigh over 100kg
Our Rating
Koala launched in 2015 in Sydney and became a household name almost overnight after their viral wine glass test video — someone jumped onto a Koala mattress next to a full glass of wine, and the wine didn’t spill. It demonstrated the mattress’s motion isolation and launched a brand that says it now has 50,000+ five-star reviews across its range and is one of Australia’s most recognised consumer brands. Koala is a certified B-Corp (meeting rigorous social and environmental standards) and donates 1% of revenue to environmental causes through 1% for the Planet. They’ve donated over $4.9 million to koala and wildlife conservation.
Their current mattress range includes the SE (entry, ~$950 Queen), Koala Mattress (mid-range, this review, $999 Queen), Plus (advanced cooling, $1,320 Queen), Polar+ (ultimate cooling), and Luxe (premium, ~$1,990 Queen). They also sell bed frames, sofa beds, furniture, and bedding. This review covers the flagship Koala Mattress — the one that made them famous.
This is what makes Koala unique among its price competitors. The top comfort layer can be flipped to choose between medium-firm (softer side up) or firm (firmer side up). It takes about 5 minutes — unzip the cover, flip the layer, zip back up. This gives you 2 firmness options in one mattress. Not as granular as Ecosa (3 settings) or Sleeping Duck (5+), but simpler and quicker to adjust. If firm is what you are after, compare it with our best firm mattress picks.
Koala’s proprietary foam technology. Unlike memory foam (slow-sinking), Kloudcell is responsive — it bounces back quickly, making it easy to change sleeping positions. 7cm of Kloudcell provides pressure relief without the “stuck in the mattress” feel. CertiPUR-US certified (no harmful chemicals).
A cooling yarn cover designed to feel cool to the touch and wick moisture. It helps with initial heat dissipation, though the all-foam construction still retains more heat than hybrid mattresses. Not removable for washing — a drawback compared to Ecosa, Emma, and Sleeping Duck.
High-density foam base with 5 support zones — firmer under the hips and lumbar, softer at the shoulders. This is the layer responsible for spinal alignment and preventing sagging over time. Provides the structural foundation for the mattress’s 10-year warranty.
Koala Mattress sits at medium-firm (~6.5/10) on the softer side, and firm (~7.5/10) on the flipped side. Most people start on the medium-firm side and stay there — it’s the more versatile setting. The Kloudcell foam is noticeably different from memory foam: it’s responsive and bouncy rather than slow-sinking. You don’t get that “stuck in the mattress” feeling. This makes it easier to change sleeping positions during the night.
For back sleepers: Good on both settings. Medium-firm provides balanced comfort; firm gives extra lumbar support. For side sleepers: Good on medium-firm — adequate pressure relief at shoulders and hips. Not as plush as Emma, but sufficient for most. For stomach sleepers: Good on firm setting — prevents hip sinking. For couples: This is Koala’s strongest category. The zero disturbance foam is genuinely excellent — the viral wine glass test isn’t just marketing. Partner movement is absorbed by the foam so the other person barely feels it.
