Design & Construction

Sleeping Duck:

The Sleeping Duck Mattress begins with a cover made of a bamboo fabric called ‘BreathTech.’ This is the first layer of the mattress. A unique design for ventilation and comfort, this garment feels soft & durable while still being sturdy. Besides being detachable and washable, this cover is also an essential component of the customization process.

This BreathTech cover is placed over an ‘AntiGravity Surface Foam’ and a ‘ComponentAdapt Customisation’ layer, both located beneath the surface foam. In this mattress, the ComponentAdapt layer is responsible for controlling the firmness of the mattress, but it is this layer that can be customized.

These comfort layers are placed on top of a multi-zoned pocket spring system (the ‘Motherboard’) that should accommodate people of all body types. This spring unit has a solid and responsive feel to it, and it provides excellent spinal support throughout all sleeping positions, including side sleeping.

Ergoflex Mattress:

Designed with excellent components that work together to create the most supportive, comfortable, and pressure-relieving mattress we have ever built, the ErgoflexTM 5-layer memory foam mattress is a great investment.

The outside cover of TENCEL® is luxuriant, natural, and breathable, while the inner layer covers and protects the whole mattress core of mattress.

A 9cm top layer of genuine high-density visco-elastic memory foam offers support while minimizing partner disturbance, ensuring undisturbed sleep for both users. n It is supported by our resistant foundation layer, which provides appropriately weighted support for the higher layers and long-term performance. The ErgoflexTM 5cm Cool-SleepTM airflow system provides for airflow as well as temperature management at the mattress’s core, and this is supported by our resistant foundation layer.

In the Ergoflex Mattress, there is a natural component.

Every Ergoflex Mattress is beautifully wrapped in a TENCEL® cover to protect it from the elements. When it comes to moisture-wicking and breathability, TENCEL® outperforms organic cotton as well as the most high-tech synthetics available. In spite of the fact that it is very powerful and long-lasting, it is also delightfully smooth and silky to the touch.

With its moisture-wicking and quick-drying characteristics, TENCELenhanced ® provides a cool, comfortable surface that allows you to sleep undisturbed and blissfully throughout the night, every night of the year.

TENCEL is naturally anti-bacterial owing to its cellular integrity, and it provides much better sanitary performance when compared to synthetics that do not need the use of chemical additives to function. TENCEL® is an excellent material for Ergoflex Mattress because of its combination of usefulness and purity.

Firmness & Feel

Sleeping Duck:

The medium-firm version of the Sleeping Duck Mattress provides excellent pressure relief and is well-balanced in its overall feel. Even though it is a little softer than some of the other medium versions that we have tested, it still provides a great deal of support.

On the firmness scale, we gave the medium version a rating of 5.5 out of 10. (where 10 is the firmest). Please remember that our firmness ratings are only intended to serve as a guide and do not necessarily correlate to comfort.

The version in the middle

As you might expect, the firmer version is firmer than the soft version (than the medium option). It maintains a good balance between comfort and support, and it responds well to changes in body position. It does a good job of maintaining body position and does not show any signs of dipping or sinking. On the firmness scale, we gave the film version a score of 7.5 out of 10.

Firm Version is the most recent version of a software program that is used to perform a task.

If neither the firm nor the medium firmness options are to your liking, you can request ‘extra firm’ or ‘soft’ foam layers to be added to the mattress to make it firmer to your liking. A noticeable difference can be felt when choosing the extra firm option, which is generally more suitable for back sleepers.

On a firmness scale of 1 to 10, we gave the extra-firm version an 8.5 out of 10. It is important to remember that our firmness ratings are merely suggestions, and they do not necessarily correlate to comfort.

Extra-Firm (Extra-firm) Version

The soft variant provides a great deal of pressure alleviation and will usually be more suitable for people who exclusively sleep on their side or stomach. On the firmness scale, we gave the gentle variant a rating of 4.5 out of 10.

The version in Soft Format

Irrespective of whatever firmness choice (or options) you choose, the Sleeping Duck Mattress provides great back support. A pocket spring structure (known as the “Motherboard”) provides a solid feeling while allowing for good spinal alignment. A restless spouse should not be an issue since relationship disruption is at an absolute minimum.

Ergoflex Mattress:

In terms of back support, the Ergoflex Mattress is unrivalled in the industry. When lying down, there should be no apparent lowering or bending, and the mattress should maintain correct spinal alignment in all positions.

Furthermore, the Ergoflex Mattress offers a feel that is similar to many TempurTM mattresses, making it a realistic option for customers who want the feel of a Tempur mattress but do not want to spend hundreds of dollars on a Tempur mattress.

The finer points are as follows:

The Ergoflex Mattress is well-constructed and seems to be of long-lasting quality. It has a consistent vibe about it, and partner disturbance is minimal. Because of the nature of memory foam, it does not have the typical “bounce” of traditional spring mattresses, which usually aids in the reduction of motion transmission between people.

This mattress has been tested and found to be non-toxic, so you can feel confident in bringing it into your home. With a simple 30-day free trial and a 10-year warranty, you’ll have plenty of confidence in your purchase. Another point worth noting is that this mattress is ideal for use with adjustable bases.

Frequently Asked Questions

Is there a cover for the Sleeping Duck Mattress?

The Sleeping Duck is covered in a natural bamboo fabric that is breathable, smooth, and antimicrobial— ideal for the changing bedroom climate. Bamboo is becoming increasingly popular among the health-conscious because it is a terrific natural fibre with a low environmental impact. Most modern brands are at the very least considering how to incorporate it into their manufacturing where it makes sense.

Is a Base Required for a Sleeping Duck Mattress?

The Sleeping Duck mattress can be used on any flat, firm surface. If you're utilizing a slatted base, the gap between the slats should be less than 8 cm, according to Sleeping Duck. The reason for this is that the pocket springs require support to work properly, and any gaps larger than 8 cm will leave a significant number of springs unsupported, hurting the mattress's comfort and life.

Is there a smell to a Sleeping Duck Mattress?

Yes, there is a scent associated with the mattress at first, but it normally goes away after a few nights.

What is the reason why ErgoflexTM does not have any displays in stores?

One of the most important parts of our initial goal was to change the conventional mattress-buying process, which we were well aware did not function well for customers. Due to the fact that we do not have physical stores, we are able to save money on the many overheads associated with them, which we can then pass on to our consumers. All of our major rivals, who were immediately following our example, started with the same strategy, but none of them has been able to keep it.

Why haven't I seen any advertisements for ErgoflexTM?

ErgoFlexTM does not utilize venture money or outside shareholder investment to finance large-scale marketing efforts since this kind of spending invariably results in a higher cost to the consumer. In reality, we've discovered from the beginning that the most effective promotion for our product and brand comes from satisfied consumers. Take a peek at some of our reviews for some inspiration.

What makes the ErgoflexTM memory foam mattress a superior option is as follows?

ErgoflexTM is the first mattress in a box brand in Australia and the United Kingdom, and we have built a reputation for providing high-quality goods and excellent customer service in the thirteen years that we have been in business. Our memory foam mattress has a material specification that is much greater than any other rival in this price range. We continue to be the only brand in our category to have been in business for a length of time greater than our guarantee term, which is a testimony to our mattresses' ability to deliver on their promises in the real world.
