Overview Of Differences

1. Mattress Design

Since the Sleeping Duck hybrid mattress uses a mixture of several elements, you can find the foam element with a pocket spring design. With Koala, polyester or polyurethane foam is used to make this high-quality mattress. It does not have springs for added structure, but it does have two sides – one firm and one medium firm.

2. Body Support 

Sleeping Duck mattress is designed to ease pressure from the main pressure points, especially if you select the firm option. On the other hand, Koala mattresses have a balanced approach and can be used by anybody.

3. Impact On The Environment

Koala is actively involved in various environmental charities, and one of its ways of supporting these causes is by donating 1% of all its proceeds. Partnering with WWF, incorporating sustainable production practices, and using clean raw materials make Koala an incredibly responsible brand.

Brand Info 

Sleeping Duck is one mattress brand that can boast about receiving multiple awards due to its research, trial, and lab testing efforts. 

In hindsight, you can best describe Koala as a brand for the people and planet because of its caring approach towards customers and the environment alike. It should come as no surprise that Koala was awarded the Canstar Blue “Most Satisfied Customers” award in 2019 and 2021 for the mattress category.

Construction And Materials

Koala uses a high-grade foam material to construct a soft yet supportive mattress. Mainly, it uses polyurethane foam as the filling, while the smooth top fabric consists of 65% polyester and 35% TENCEL Lyocell fibres. 

Sleeping Duck uses Airgrown polyurethane foam to provide extra density to the mattress. The porous and breathable material feels cushiony, providing the sleeper comfort in all sleeping positions. It also uses twice-tempered steel springs that support specific zones of the body. 

Comfort, Firmness And Feel

Since the Koala mattress has an anti-slip base fabric and pure foam construction, the mattress feels soft and super comfortable to sleep on. It also gives you the option to select the firmness level by flipping the mattress, and we think this caters to a wide range of sleepers. 

Alternatively, the Sleeping Duck mattress feels soft and cool to sleep on, thanks to the breathable bamboo cover.

Finer Details

A. Shipping, Trials, Returns And Warranties 

Koala offers quick, free shipping of its products with a 10-year warranty. Before you commit to the mattress, the makers offer 120 nights as a free trial to help you make a decision. While Sleeping Duck offers a similar warranty, its trial period lasts for 100 days only. 

B. Sinkage, Bounce, Edge Support And Motion Isolation

Both the options provided exceptional motion isolation and adequate bounce while sleeping. The Sleeping Duck mattress is better at delivering edge support due to the pocket springs that hold the structure in place. 

The Koala mattress has a firm support base that prevents the body from sinking. Similarly, the Sleeping Duck handles body weight evenly due to its hybrid nature. 

Buyer Feedback

Most buyers said that Koala was a comfy mattress that felt just right in terms of bounce and balance. People who were starting to make conscious decisions to buy eco-friendly products preferred Koala over any other brand. 

There was one thing, however, that many reviewers mentioned about the Sleeping Duck mattress – the fact that it caused minimal partner disturbance by containing movements of an active sleeper.

Final Verdict on Sleeping Duck vs Koala

After going through all these details about the two mattresses, we concluded that both options are different and will appeal to particular demographics.

However, Koala mattresses are more popular, affordable, and accessible to most people. Sleeping Duck, on the other hand, has good quality products, but they are expensive and may not appeal to all.
