⚡ Quick Verdict
Ecosa wins for solo sleepers and budget buyers — excellent value with adjustable firmness and a 15-year warranty.
Sleeping Duck is better for couples needing split firmness per side, and hot sleepers wanting hybrid airflow.
Overview
Both Ecosa and Sleeping Duck offer adjustable firmness — but that's where the similarity ends. Ecosa is all-foam at a budget price; Sleeping Duck is a premium hybrid at nearly double the cost.

Comfort & Feel
Both mattresses deliver strong comfort for most sleepers, but approach it differently. The Ecosa uses Foam construction with a Adjustable feel. The Sleeping Duck offers Hybrid construction with a Adjustable feel. For most Australian sleepers, both provide adequate pressure relief — where they differ is in feel and adaptability.
Cooling & Temperature
Between these two, Sleeping Duck wins on cooling. The pocket spring base creates natural airflow channels that all-foam mattresses simply cannot replicate. In Australia's summer heat, this is a real advantage.
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 Ecosa Mattress is priced at $799 AUD for a Queen. The Sleeping Duck Mach II comes in at $1,399 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
Ecosa wins easily for solo sleepers — $600 less, 15-year warranty, adjustable firmness. Sleeping Duck Mach II is worth every extra dollar for couples — per-side split firmness is a feature no other Australian mattress offers, and the hybrid construction runs genuinely cooler.
You want solo sleepers and budget buyers — excellent value with adjustable firmness and a 15-year warranty.
