Comfort & Feel
Both mattresses deliver strong comfort for most sleepers, but approach it differently. The Ergoflex uses Memory Foam construction with a Medium-Firm feel. The Koala offers Foam construction with a Medium feel. For most Australian sleepers, both provide adequate pressure relief — where they differ is in feel and adaptability.
Cooling & Temperature
Both mattresses use foam construction. Neither has a strong cooling advantage — though open-cell foam formulations from both brands improve breathability compared to traditional dense memory foam.
For very hot sleepers, pairing either mattress with breathable linen or bamboo bedding makes a significant difference regardless of the mattress itself.
Price & Value in Australia
The Ergoflex 5G Memory Foam is priced at $1,395 AUD for a Queen. The Koala Original Mattress comes in at $1,050 AUD. Both brands run major promotional events — EOFY, Black Friday, and Click Frenzy typically offer 15–40% off. Check our deals page before buying either.
Our Verdict
Koala wins for most buyers — $345 cheaper, longer trial, longer warranty, better cooling, higher rating. But if a physio has told you to prioritise lumbar alignment above everything else, Ergoflex's specialist high-density memory foam delivers targeted support Koala doesn't match.
