Sleeping Duck MACH II Mattress Review

Although the Sleeping Duck founders were unsuccessful in landing a deal on Shark Tank Australia (back in 2017), they continued to expand their online mattress-in-a-box business entirely on their own funds, generating over A$30 million in sales in FY21.

What a motivating tale! I’ll now get to the review itself:

The updated Sleeping Duck mattress is known as the Sleeping Duck Mach II (or SD Mach II). Similar to its predecessor, it features a distinctive, modular design and a hybrid pocket coil with firmness adjustability that can be swapped out and altered as needed to create the ideal sleeping arrangement. But is Sleeping Duck’s new mattress just “quack” or is it the cutting-edge, intelligent bed that Australians have been waiting for?

We set out to provide a conclusive response to that query.

Sleeping Duck MACH II Mattress Review

Sleeping Duck Mach II Mattress Review Summary​

There aren’t many bed-in-a-box companies that provide hybrid mattresses, and even fewer that do. The only company in Australia that offers all three seems to do so well: Sleeping Duck. However, SD Mach II is quite expensive compared to other online mattress brands, with prices starting at $999.

With low sinkage, the SD Mach II mattress provides you the sensation of sleeping “on” rather than “in” the mattress. Some people may enjoy the sensation, particularly those switching from innerspring mattresses, but if you’re looking for a mattress to sink into or intense pressure alleviation, this is not going to be it.

You can first order all-firm, all-medium, or half-and-half (one side firm, one side medium). After a 21-day break-in period, if you’re not satisfied with the firmness, you can ask to exchange the layers or decide between an extra firm and a soft layer. This mattress’ modular construction, which enables you to switch out any of the six foam pads on either side and precisely alter the hardness to your preference, is its standout feature.

On a scale of firmness, the firm felt like 7.5/10, while the medium felt like 6. For reference, the medium-firm industry norm is 6.5. Therefore, neither the medium nor the firm options are excessively soft or rigid.

The mattress effectively relieves pressure points while offering even body support. The zoned construction would be appreciated by those who have pain or discomfort in their shoulders, hips, or back as they sleep, and they may also experience pressure alleviation (talk to your doctor for more detailed advice).

Back sleepers, stomach sleepers of light to medium weight, side sleepers of average to heavy weight, and combination sleepers may all benefit greatly from the SD Mach II. Larger side and stomach sleepers, however, can discover that their hips sag too far in either position.

You won’t likely feel your partner’s movements if you share a bed because the motion isolation is fairly good. It has decent edge support, so you may sit or sleep on the side of the bed without worrying that you’ll fall off. The mattress may trap too much heat for some people. Additionally, the mattress is difficult to assemble, move around, or change the sheets due to its weight (52 kg for a queen).

Like any other online mattress brand, SD Mach II includes a 100-day trial, a 10-year warranty, and free shipping.

Who may love the mattress?

  • Those seeking a hybrid mattress that is both supportive and springy.
  • Those who value customization (six modular pads) or prefer options for firmness (medium or firm).
  • Couples: The half-half design enables separate customization of each side of the bed.
  • It would be simple for combination sleepers to change positions throughout the night.
  • This mattress can be appealing to those seeking pain treatment.
  • Those seeking a sturdy mattress at a reasonable cost.

Who may not love the mattress?

  • Those trying to find a cheap mattress.
  • Individuals seeking a nice mattress.
  • Stomach and side sleepers who are heavier.
  • The hot sleepers.

Sleeping Duck MACH II

Sleeping Duck MACH II

You have a lot of customization choices with SD Mach II. an excellent mattress for people who need support in particular places or are searching for a bed that is supportive overall.

Firmness & Feel

Let’s examine the firmness settings that are offered and how the SD Mach II truly feels on various body types and sleeping positions.

How firm is the SD Mach II mattress?​

Our testing revealed that the medium setting has a 6/10 feel, making it marginally softer than medium-firm. The firm choice felt about a 7 out of 10. The mattress is neither a true medium nor a true firm mattress, with the industry average for medium-firm being 6.5 and firm being at 8.

Additionally, Sleeping Duck provides extra hard and soft pads, which you can order for free for the duration of the trial and for $150 after that. Since they are not a component of a typical mattress, we were unable to test them.

Both configurations retain the same soft top antigravity foam layer. The transition layer, which is stiffer than the componentAdapt foam that follows, is where you can replace the firmness strip or the individual pads. The coil at the bottom layer is quite supportive and robust. Overall, the mattress has little sinkage and strikes a decent mix between comfort and support.

Of course, we use the mattress firmness scale as a benchmark, but a mattress’s feel is still entirely arbitrary. One individual may sense that a 7/10 is hard, while another may feel that it is “soft”. These rankings should only be used as general recommendations, not as exact measurements.

Sleeping on the SD Mach II mattress

We had a decent blend of support and comfort while sleeping on our backs in the firm configuration. While the foundation coil layers provided ample of lumbar support, the top layer caused our hips to slightly sink in. Back sleepers might favor the firm setting over the medium setting.

We had some slight pressure around the hips while side sleeping in the medium setting, but nothing major. In comparison to heavier sleepers, light- and average-weight sleepers would benefit from superior pressure reduction around the hips and shoulders. In general, side sleepers might not be comfortable in the firm arrangement.

We experienced reasonable support in the firm setup when stomach sleeping. However, in either position, our heavier tester felt their hips dipping into the mattress. Thus, SD Mach II may be more comfortable for lighter and average-weight stomach sleepers than for heavier ones.

What Does The SD Mach II Feel Like?​

The Sleeping Mach II’s surface is springy and sensitive. Being more “on top” of the mattress as opposed to “in it” when you sleep makes it simple to move around on the bed. Although it’s not overly fluffy, the top layer has a touch that is similar to a pillow top.

Average Weight Sleepers (60-100 kg)

We believe that the two firmness options would provide adequate support for average-weight individuals in a variety of sleeping positions. The mattress would provide a comfortable blend of comfort and pressure reduction for people of average weight. Back and stomach sleepers may wish to choose the harder side, while average-weight side sleepers may prefer the medium side.

Heavyweight Sleepers – (above 100 kg)

The mattress can be a perfect fit for back sleeping for heavy people. Side sleepers may not experience the ideal pressure alleviation at the hips and shoulders in this weight range and may feel squished. Similar to this, heavy people who sleep on their stomachs could not find the mattress to be sufficiently supportive, resulting in their hips bowing into the mattress.

Lightweight Sleepers (40-60 kg)

Lightweight sleepers should do well on the mattress in the majority of sleeping positions. This category would offer ample of pressure relief for side sleepers, a supporting surface for stomach sleepers, and a decent balance of support and comfort for back sleepers.

Construction

Construction

It feels just like a rocket ship given the names Sleeping Duck gave to the many layers that make up the mattress! The motherboard base layer, componentAdapt transition layer, antigravity foam layer, and yes, the mattress is called Mach II are all present. But resist feeling overpowered. Although there are many customization choices, the process is rather simple.

Let’s take a look inside it to discover what each layer does for the mattress as a whole.

Construction

Cover (Breathetech)

The SD Mach II has a knitted bamboo fabric cover on top that is breathable, elastic, soft, and encourages airflow. Additionally, it is robust, antibacterial, and hypoallergenic by nature. Its outer cover has a zipper, making it simple to unzip and take off for cleaning or washing.

Antigravity foam layer

That is a fancy name, huh? The 5 cm thick special antigravity foam layer from SD gives the softness of memory foam without the quicksand sensation or heat, as well as bounce and responsiveness similar to latex. The layer is allegedly exceptionally sag-resistant, porous, and breathable.

When touched, it has a neutral, balanced feel that is neither too stiff nor too soft.

The foam is sturdy to keep you in place while being flexible to allow you toss and turn without encountering any resistance. This layer was created in Australia and has GECA approval. The layer, according to the manufacturer, is also very sag-resistant.

The layer’s function is to provide some pressure relief and contouring before the transition layer—where the true support is—takes over.

ComponentAdapt Transition Layer

This is the removable layer that contains the foams with adjustable and varied firmness. Twelve rectangular polyurethane foam pads of varying firmness make up the center layer, which is available in firm, medium, or half-half settings, with six for each half of the bed. By unzipping the lid, you may switch these out and rearrange them anyway you like. Need the shoulders to be a little firmer?

You will receive a “firm” panel insert from Sleeping Duck for the mattress’ shoulder area. That just applies on your side; your spouse can choose the hardness of their shoulders as they see fit. During the first 100 nights of ownership, you can really get a new half side or fresh foam cushions; just phone customer service to make the request. In comparison to SD Mach I, switching out the foams is now considerably simpler. You can get gentle and extra firm pads in addition to medium-firm and firm pads during the trial time and purchase them later.

Motherboard (Base support layer)

What distinguishes the Sleeping Duck mattress as a “hybrid” is the final layer of pocket springs. The brand states that the steel coils are practically unbreakable and have undergone two tempering processes.

Each steel spring is contained in its own pocket, allowing them to act independently and respond to the pressure you provide throughout the course of the night. Additionally, pocket springs balance off some of the hardness from the foam, giving the mattress a better “all-rounder” that can accommodate a variety of sleepers’ needs. Last but not least, the pocket spring layer’s 5 zone support feature allows the five zones of the sleeping body—head and shoulders, back and spine, hips and lower back, legs and knees, and feet and ankles—to receive customized support. In order to provide better edge support and keep you from rolling off, the mattress’ perimeter has been significantly reinforced.

Mattress Height

The SD Mach II mattress is thicker than typical all-foam beds at 12″, or 31 cm, which is standard for hybrid mattresses.

SD Mach II Price & Size Options

Without a doubt, the SD Mach II mattress is a high-end item with a price tag to match. Single starting at $999 and King at $1,999. Keep in mind that the price of ordering substitute foam panels during the first 100 nights is also covered; you are not responsible for paying Sleeping Duck for the replacement panels, and you are not required to send back the ones you don’t need.

Mattress Performance

After learning about the variety of customization possibilities, let’s examine the mattress’ capabilities in terms of temperature regulation, edge support, motion isolation, and durability.

Sleep temperature

Due to the substantial space for ventilation provided by the pocket coil layer, hybrid mattresses often sleep cooler than foam beds. The larger comfort and transition layers did, however, cause us to feel as though the mattress did trap some heat. The SD Mach II might not be the best choice if you have a warm sleeper.

Motion Isolation for Couples

Unexpectedly, the Sleeping Duck performed a fantastic job of minimizing movement throughout the surface for a hybrid mattress. This is attributed to the substantial comfort and transition layer, which is effective in localizing motion. Nevertheless, compared to all-foam mattresses like the Emma or Koala, the motion transmission was still greater.

When we pressed down on the mattress and placed a glass of water on one side, the glass did wobble somewhat, but not enough to spill any liquid. Keep in mind, especially if you’re a light sleeper, that partners might be able to detect movement on the mattress.

Edge Support

In our tests, we found that the Sleeping Duck provides sturdy edge support all the way around. It is simpler to get into and out of bed thanks to the strengthened pocket springs’ effective prevention of sinkage and roll-off.

The comfort layers may somewhat sag when you sit or sleep towards the borders, but the base coil layer is highly sturdy and keeps you from feeling like you’re about to fall off.

Compared to all-foam mattresses like the Koala, Ecosa, or Emma, the SD Mach II provides stronger edge support overall. But while the comfort and transition layer is thicker than typical, it falls short when compared to hybrid mattresses.

Noise

We moved around on the mattress without hearing any creaking or squeaking noises. The larger comfort and transition layers helped the mattress maintain a rather peaceful surface, despite the fact that pocket coils are slightly louder than all-foam mattresses. However, with time, the noise produced by the pocket coils can increase.

Sex Comfort

Intimate sleeping couples typically like a mattress that is responsive, bouncy, and easy to move about on. The balanced foam feel and hybrid composition make it an excellent complement for sexual partners.

Off-Gassing

When we initially opened the Sleeping Duck’s box, we did detect an initial chemical odor, as is typical of most mattress-in-a-box products. However, after letting it air out for 24 hours, the smell vanished entirely.

Durability

The Sleeping Mach II appears to be well-made and incredibly robust when examining the foam layers and solid steel coils. With the right upkeep, the mattress should last between seven and ten years.

The mattress also underwent a simulated 8-year test of wear and tear, and it did rather well.

Company Policies

It’s crucial to completely comprehend the retailer’s return, warranty, and shipping procedures before purchasing a new mattress. Let’s examine Sleeping Duck’s performance in these areas.

Warranty:

Every layer of the mattress in the SD Mach II is covered by a 10-year guarantee (covering sagging of 8% or more of each layer). The Sleeping Duck will replace any layers that droop more than the acceptable amount without charging you anything.

The guarantee does, however, come with some restrictions (as is customary in this sector). The guarantee only applies to mattresses that are put on suitable bases (not spring bases or adjustable bed bases), and you must provide photographic proof in order to be eligible for it. Furthermore, the warranty cannot be transferred. In light of this, it’s critical to care the Sleeping Duck mattress properly to secure ongoing support from the business.

Sleep Trial:

You may thoroughly try the Sleeping Duck mattress in the comfort of your own home for a full 100 nights thanks to the mattress’ free trial offer. After the 21-day break-in period, you can ask for a free switch to the softer or stiffer version of the same mattress if you’re not satisfied with the firmness. You can return the mattress for a complete refund if you’re still unsatisfied.

Shipping and Delivery:

Sydney, Melbourne, Brisbane, Adelaide, and Perth are just a few of the main Australian cities where Sleeping Duck provides free shipping and next-day delivery. The delivery may need up to eight days if you reside in a rural place.

It’s a good idea to have assistance while opening and putting up the mattress because the box is somewhat hefty. After being opened, it takes many hours for it to unfold and acquire shape.

For an extra fee, Sleeping Duck also provides white-glove delivery, which takes care of both mattress removal and setup in your room. In a few parts of Sydney, Melbourne, Geelong, and the Surf Coast, white-glove delivery is offered.

How Does The Sleeping Duck Mach II Compare To Other Mattresses?

Mattress purchasing may be challenging, but doing some comparison shopping can always be helpful. The Sleeping Duck II was put up against Ecosa and Koala, two of the most well-known internet mattress manufacturers in Australia.

Sleeping Duck Mach II vs Ecosa.

The Sleeping Duch Mach II and Ecosa are built very differently. The SD Mach II is a hybrid mattress with pocket coils, in contrast to the Ecosa, which is a foam mattress. Therefore, it cannot be compared apples to apples. However, both mattresses come with the usual bed-in-a-box features, such as free shipping and returns, a 100-day trial period, and the ability to change the firmness.

Soft, medium, and hard stiffness variations are available in Ecosa. The layers can be rearranged to fulfill all three goals. Contrarily, the Sleeping Duck Mach II is only offered in two hardness levels: medium and firm, or half-half design.

Ecosa and SD Mach II feel quite similar to one another. Both exude a feeling of warmth and responsiveness. However, due to the modular construction of SD Mach II, you may adjust the stiffness at the sectional level (six on each side). Ecosa just has one feel the entire time.

Having said that, Ecosa may be a wonderful substitute for Sleeping Duck Mach II unless you’re a larger person, require half-half design, or have certain regions where you need specialized support (medium or firm). Additionally, Queen size Ecosa is $720 less expensive than SD Mach II. Therefore, the Ecosa mattress is something to think about if money is a concern.

Sleeping Duck Mach II vs Koala.

The SD Mach II is a hybrid mattress, whereas the New Koala is an all-foam mattress like Ecosa. Koala and SD Mach II both have the ability to change the hardness setting between firm and medium. Only Sleeping Duck Mach II has a half-half design, though. The medium and firm sides of the new Koala mattress are softer than those of the SD Mach II.

If you want a somewhat plush mattress or require more pressure relief, the new Koala is a fantastic choice. The SD Mach II is a good option for larger people, couples who want varying levels of hardness, or anyone searching for a supportive mattress.

Similar to Ecosa, Koala is roughly $500 less expensive than the SD Mach II (Queen size).

Buyer Feedback & Complaints

In order to do extensive research, we combed the web, analyzing more than 200 real reviews from Australian customers, and understanding the real Sleeping Duck customer experience. The average customer rating across all platforms was 4.5 out of 5.

  • 82% of customers gave the mattress a 4.5+ (out of 5) rating and expressed complete satisfaction.
  • The majority of customers were pleased with the customer service.
  • For 5% of the sleepers, the mattress was overly heavy, making getting into bed difficult.
  • 8% of customers reported sleeping overheated while on the mattress.
  • 14% of customers said they liked how firm the mattress was.
  • In the first six months, 4% of consumers reported that the mattress started to droop.
  • 6% of the sleepers complained that the quality was subpar given the cost.

Although there are occasional case-specific complaints, the vast majority of consumers are satisfied with their Sleeping duck mattresses.

Bottomline

You have more customization possibilities with SD Mach II than with any other mattress on the Australian market. Yes, finding the various firmness pads requires some back and forth, and installing them is not the easiest process, but if you need that additional touch of customization for your mattress, it can be worth the extra work. Naturally, all of this costs more than the majority of internet mattress brands. The Ecosa mattress is a good option if you’re on a tight budget and don’t want modularity, while the New Koala is a respectable substitute if you require something plusher or softer.
