Two of Australia's most popular foam mattresses go head to head. Here's how the Sleeping Duck Mach II and the Ecosa Mattress compare on comfort, support, cooling, value and after-sales service.

Comfort & Feel

The Sleeping Duck Mach II uses a micro-coil layer beneath foam, giving it a slightly more responsive, hybrid feel compared to the Ecosa's all-foam construction. The Ecosa uses a layered foam system where you can physically rearrange the internal foam layers to change the firmness — a unique feature at this price point.

Value for Money

The Ecosa is significantly cheaper and often goes on sale for $599–$699. For budget-conscious buyers, it represents exceptional value. The Sleeping Duck commands a premium but delivers a more premium in-sleep experience for back and stomach sleepers who need firmer support.

Who Should Buy Each

Sleeping Duck Mach II suits back sleepers, stomach sleepers and anyone who runs hot at night (the micro-coil layer improves airflow).

Ecosa suits side sleepers, couples with different preferences (you can adjust each side), and buyers watching their budget.
