Overview Of Differences- Ikea Vs Sleeping Duck Vs Koala

Before we take you through the detailed comparison of these mattresses, here’s a quick summary of some important factors to keep in mind while choosing between them.

1. Body Support

The spring mattresses from Ikea help with proper body support and even body weight distribution so that you get optimum comfort. Besides, the latter plays a crucial role in prolonging the life of mattresses. And there’s at least one layer of foam in the spring mattress for extra comfort.

Likewise, the foam and latex mattresses can be ideal for people looking for something that can adapt well to their body contours without compromising support or comfort. Finally, the hybrid mattresses use a combination of spring and foam for enhanced pressure relief and sturdiness.

Talking about the Sleeping Duck SD Mach II mattress, its hybrid construction gives users a feeling of weightlessness while ensuring proper support to their pressure points. On the other hand, the Koala mattress has a more targeted support system, primarily below the hip, to keep the sleeper from sinking.

2. Movement Resistance

All kinds of mattresses from Ikea offer movement resistance to a certain extent. For instance, the spring mattresses have at least one layer of foam to absorb body shocks, while the memory and latex mattresses provide enhanced movement resistance by adapting to the body contour of the sleepers.

Coming to the Sleeping Duck SD Mach II mattress, its bamboo knitted cover and anti-gravity surface foam work together to provide “delayed” movement transfer. This means you may still experience motion transfer, especially if your sleeping partner loves tossing and turning around.

However, the Koala mattress is a better choice in terms of movement resistance as its zero disturbance technology completely negates motion transfer.

Brand Info

With over six decades of operation on the global market, Ikea is one of the top names for affordable and practical home-use products. Today, it has more than 600 physical stores in North America, Asia, Europe, Africa, the Middle East, and Oceania. 

Besides, Ikea has been the proud recipient of many prestigious awards, like the Red Dot award for product design and the Circular Economy Award for its sustainable practices.

Sleeping Duck started operations in 2014 and is the manufacturer of the world’s first fully customisable mattress. But that’s not the only thing that sets this brand apart from a lot of its peers. It has also been recognised for its top-notch customer service, making it the winner of the Australia Post Orias award for the best customer service in 2020.

Koala also started in 2015, but it has already won praise for its high-quality and sustainable products. Its mattress line, in particular, has been the winner of the Canstar Blue “most satisfied customers” category in 2019 and 2021. Moreover, it’s committed to helping the Koala population of the country thrive by planting and protecting two billion trees.

Construction And Materials


The construction and materials of the Ikea mattresses will depend on the exact model you opt for. 

For instance, you will find both pocket spring and innerspring mattresses in the spring mattress category. While the former has individually wrapped springs for more targeted support, the latter comes with a uniform spring system for proper weight distribution. In addition, there’s a soft filling that renders uninterrupted comfort and support.

The mattresses also have a stretch fabric as the topmost layer, which adapts to your body movement so that you can easily change your sleeping position.

Aside from that, the latex and memory (including memory foam) mattresses are designed with body contouring in mind. These soft and flexible yet durable mattresses provide the desired support and comfort, no matter your sleeping position. Moreover, the knitted ticking cover provides directed support to your neck, shoulders and hips for significant stress relief.

Sleeping Duck

The Sleeping Duck SD Mach II mattress has four distinct layers, the first of which is the BreatheTech cover. Made from vortex-spun bamboo fabric, its silky soft texture is extremely breathable and gentle on the skin. 

Next is the high-density, porous AirGrown polyurethane anti-gravity surface foam layer, which serves the dual purpose of aiding breathability and making the mattress lightweight.

The third layer is also made from the same material and comes in medium or firm options so that sleepers can choose one according to the desired feel. 

Lastly, the motherboard multi-zoned system comprises twice-tempered steel springs, which provide concentrated support and make the edges sturdier to sleep on. This essentially increases the sleeping surface of the mattress, and the edges don’t sink even with prolonged use. 

Koala Mattress

The Koala mattress has a relatively simple construction, consisting of two layers of foam and a Tencel Lyocell cover. Its highlight is the double-sided comfort layer that can be unzipped and flipped to choose between medium-firm and firm support.

Besides, the firm support base helps maintain the right sleeping posture, irrespective of your sleeping position. The mattress design rests on a 100% polyester fabric base with integrated anti-slip PVC dots, which prevent it from sliding around.

Comfort, Firmness And Feel


The diverse range of Ikea mattresses allows buyers to choose the right option according to their comfort and firmness preferences. While the spring mattresses offer better body support, the foam and latex mattresses excel in body contouring and movement shock absorption.

Plus, you can choose from different firmness levels according to your needs.

Sleeping Duck

The BreatheTech cover makes the mattress soft to sleep on, while the anti-gravity surface foam provides a lightweight feel. This means you can sleep comfortably without experiencing any sinking. And its biggest advantage is the customisable firmness option, where buyers can choose either a firm or medium-firm variant and customise it to their liking.


Much like the SD Mach II, the Koala mattress can be used to receive firm or medium-firm support. In either case, the sturdy support base keeps your lower body in the right position to aid pressure relief and prevent sinking.

Moreover, the Tencel Lyocell fabric simultaneously absorbs and wicks moisture to ensure a cool and soothing sleep surface.

Ikea mattresses are available in queen, king, twin, and full sizes. The best part is the prices won’t burn a hole in your pocket, making them ideal for almost all budgets.

Sinkage And Bounce

The spring, foam and latex mattresses from Ikea perform a decent job in keeping your body properly positioned to prevent you from sinking in. However, the shock absorption of the foam and latex mattresses may not offer too much bounce.

The Sleeping Duck SD Mach II mattress doesn’t have any significant sinkage either, but the pocket springs at the bottom make it more reactive than its peers. And the Koala mattress is neutral, meaning there’s no considerable sinkage or bounce.

Edge Support

When it comes to edge support, the Sleeping Duck SD Mach II beats both Koala and Ikea with its steel springs, which provide reinforced edge support.

Customer Feedback

Ikea mattresses are preferred by people who want affordable options, irrespective of the material and firmness level. However, both the Sleeping Duck and Koala mattresses have been praised by sleepers who want to target specific problems like pressure relief, breathability and proper edge support.

Ikea or Koala mattress

Ikea and Koala cater to different needs in the mattress market. Ikea offers a wide range of affordable mattresses, including latex, foam, and spring options, known for their durability and variety. They provide a 10-year warranty and a 90-night trial, with additional shipping costs. Koala, an Australian brand, stands out with innovative designs like zero disturbance technology and a three-zone support system in their mattresses, priced at $1,099 for a queen size.

They also offer a longer 120-night trial, a 10-year warranty, and free delivery. While Ikea is ideal for budget-conscious buyers seeking variety, Koala appeals to those looking for advanced, eco-friendly mattress technology with enhanced comfort.

Ikea or Sleeping Duck mattress

Ikea and Sleeping Duck present unique offerings in the mattress sector. Ikea stands out for its affordable, diverse range including latex and foam options, backed by a 10-year warranty and a 90-night trial, though shipping costs extra. Sleeping Duck, on the other hand, specializes in customizable mattresses like the SD Mach II, priced at $1,649 for a queen, with free shipping, a 100-night trial, and a 10-year warranty.

While Ikea appeals to those seeking variety and value, Sleeping Duck caters to customers looking for personalised comfort and innovative design in their mattresses.

Final Verdict

The Ikea mattresses may be better suited for people who don’t want to splurge much on bedding. And the Koala mattress is worth considering if you want to switch between firmness levels without changing the mattress.

The Sleeping Duck SD Mach II mattress is great if you want customisable firmness and better edge support without sinking in or bouncing around. However, it comes at a price. 

If you want a mattress that sits in the middle of the price range but offers excellent comfort, stick with the Koala mattress
