Sleeping Duck Mach II vs Ecosa Mattress Comparison Overview

Sleeping Duck vs Ecosa Mattress

Need solutions right away? We understand that time is a luxury, therefore we’ve compiled the main distinctions into this convenient overview.

Construction – The Sleeping Duck takes pride in offering a hybrid construction that combines the advantages of both memory foam and pocket springs. On the other side, Ecosa is a mattress made entirely of foam.

Styles of Customization – The sleeping duck allows you to select the hardness for each region of the mattress (up to ten distinct “zones”) even though customization is only possible during the first 100 nights of ownership. Contrarily, Ecosa does not offer that modular, zone-specific design, but it does offer three firmness levels that may be switched out totally whenever you choose.

Price: At around $1849 for a queen size, Sleeping Duck is by far the most expensive mattress-in-a-box offered in Australia. In contrast, the cost of an Ecosa mattress is approximately half that of a sleeping Duck mattress, with a queen size costing between $800 and $900 (depending on current promotions).

Comfort & Feel: Sleeping ducks may be helpful for people that have certain pain locations, need firmness for a particular body part, or are in a relationship and have varied sleeping preferences. In contrast, Ecosa is a straightforward mattress made to fit the needs of the majority of sleepers. Additionally, Ecosa firmness can be adjusted to accommodate all different types of sleepers, ranging from velvety soft to extremely hard.

Brand Info – Sleeping Duck vs Ecosa

These two businesses, which were both established in Australia just one year apart (Ecosa in 2015 and Sleeping Duck in 2014), have grown into formidable rivals in the country’s mattress-in-a-box sector and have each won a number of awards. Three years running, the Sleeping Duck mattress was a CHOICE “top rated” pick, and in spite of all its flaws, it was given a Good Design award. Ecosa also received a Melbourne Design “Silver” award and the “Best Mattress for Couples” title from So both mattresses have received recognition, but how do they fare in the real world?

Construction – Sleeping Duck vs Ecosa

The Sleeping Duck Mach II mattress employs foams that are GECA approved, but the Ecosa mattress uses foams that are CertiPur certified and Oeko-Tex 100 certified. The bottom line is that both mattresses are fully safe for human exposure and free of any dangerous substances.

Now that we are aware of their safety, what else can these materials provide?

Sleeping Duck Mach II

Two foam layers atop a pocket spring base, all topped with a bamboo cover. In total, reaching 31cm high.

The bamboo cover, which is naturally antibacterial and permeable, offers cooling and comfort.

A layer of hyper-adaptive foam combines the ‘bounce’ of latex with the pressure-relieving properties of memory foam.

The high-density polyurethane foam, which is adaptable, controls the stiffness of the mattress—it can be medium or firm.


Three swappable foam layers and two covers (one removable), coming in at 25cm high.

The initial cover is machine washable and made of breathable Tencel.

German micro-filament technology was used to create the inside cover, which is waterproof and dust mite-resistant.

The first layer (by default) is G-7 memory foam that has been infused with gel to provide pressure relief and additional cooling characteristics. The ergonomic support foam that follows helps with spinal alignment and offers effective motion isolation.

Comfort, Firmness and Feel – Sleeping Duck vs Ecosa

Both mattresses are highly customizable, therefore it’s difficult to generalize about their hardness and feel because it all relies on the preferences of the buyer. However, in general, the Sleeping Duck’s pocket spring base provides a bouncy, more responsive sleeping experience, ranging from a “medium” to a “firm” sensation. ‘Medium’ and ‘Firm’ options are also available from Ecosa, as well as a ‘Medium-Firm’ choice in between the two. However, because of its three foam layers, it offers a slightly less springy sleeping experience overall.

Sleep Position Ratings – Sleeping Duck vs Ecosa

The Sleeping Duck mattress attempts to accommodate all sleeping positions with its two firmness levels, which range from around 6 to 8 on the mattress firmness scale. Back and front sleepers will generally choose the ‘hard’ option, while side sleepers would likely prefer the’medium’ option. Thanks to its responsive 5-zone pocket spring basis, even heavier sleepers will be comfortable here.

The Ecosa mattress is even superior to the Sleeping Duck mattress in terms of all sleeping positions. The Ecosa mattress has the added advantage of accommodating combination sleepers whose preferred sleeping position changes because it offers more firmness options and the flexibility to switch between them at will. The mattress is a fantastic choice for anyone with back pain difficulties because of its sturdy, all-foam construction.

Sinkage, Bounce, Edge Support and Motion Isolation – Sleeping Duck vs Ecosa

Bounce and Sinkage

Despite the fact that both mattresses are made of memory foam, which naturally has “sinking” characteristics, neither one of them commits too heavily to the sensation of being “swallowed up” by the mattress. In fact, the pocket spring base of Sleeping Duck and the “latex-like” ECO-Tex foam layer of Ecosa both provide a nice amount of bounce.

Edge Protection

The Sleeping Duck mattress is a clear winner in terms of edge support because to the steel gauge coils that surround the base of the mattress. Even while Ecosa’s foam is not worse in that regard, it just cannot compete.

Isolating motion

In sharp contrast to the edge support features offered by the various mattresses, Ecosa stands out as the winner in terms of motion isolation (as shown by the brand’s popular “wine glass” video). With its three foam layers, notably the thick support foam layer, you can expect an exceptionally stable and peaceful night’s sleep. Unfortunately, Sleeping Duck’s hybrid design falls short in this instance. Although individually pocketed springs perform better at motion isolation than standard springs, they can’t compete with foam’s triple threat.

While the Sleeping Duck is undoubtedly a superior option for heavier people and both mattresses provide excellent sleeping experiences that accommodate all sleeping positions, we can’t help but favor the Ecosa mattress overall. Unlike the Sleeping Duck, which only permits customization for the first 100 nights of use (the trial period), Ecosa’s mattress can be altered whenever you like with no trouble.

Five years into owning an Ecosa mattress and want a change? No issue! There is nothing preventing you from opening the outside cover and moving about. We are choosing the Ecosa mattress because of this as well as its unmatched motion isolation qualities.
