Delta Sleep Mattress Review


Before dissecting the attributes of the Delta Sleep mattress in detail, let’s get cosy and comfortable on it. Can you feel its many supportive layers cushioning your body? On that note, let us highlight the best bits about this mattress, providing an insight into its popular features. 

  • Intellicool technology for breathability and airflow
  • Soft, moisture-wicking Tencel cover 
  • Adaptive comfort technology for support 
  • Soothes the joints 
  • Zero partner disturbance for sound sleep 
  • Made from Australian materials and eco-friendly 
  • 120-night trial period 
  • 10-year guarantee 
  • Anti-sag and GECA-certified 
  • Three support layers 
  • Ultra-Fresh antimicrobial coating 

How Does The Delta Sleep Mattress Feel To Sleep On?

The most important thing while choosing a mattress is how it feels to sleep on, and this Delta Sleep mattress doesn’t disappoint, thanks to its adaptive comfort technology. Comprising three layers, consumers can enjoy a night of peaceful sleep with the top layer cushioning their bodies. 

It conforms to a person’s natural alignment, reducing the chances of body aches when you wake up the next day. Moreover, this high-density foam-top support layer eliminates partner disturbance, perfect for people who share the bed with restless sleepers. You won’t feel disturbed even if your partner keeps tossing and turning through the night. 

The best part is that the mattress stays cool in summer and warm in winter, which brings us to its Intellicool technology. This Australian technology ensures greater airflow even on humid nights. Thus, it’s suitable for hot sleepers, guaranteeing greater breathability by releasing excess heat from the body to create a comfortable sleep environment. 

And adding to the breathable nature is the Tencel foam cover, made from environment-friendly and sustainably-sourced materials. All these factors result in the mattress having soft, breathable and moisture-wicking properties.

Naturally, most people wake up energised after sleeping on the Delta Sleep mattress. But that’s not all, as the brand has researched mattresses from rival brands to avoid shortfalls like sagging. You’ll find that this product prevents neck, hip, and spine pain due to its anti-sagging properties. 

What’s The Delta Sleep Mattress Made From? 

A. Natural Materials 

A mattress that allows you to sleep well will surely have quality materials, but the Delta Sleep mattress has gone a step further by using sustainable raw materials. As a result, it’s completely eco-friendly and doesn’t use any solvents or harsh chemicals, while allowing the manufacturer to design three comfort layers. 

B. Comfort Layers 

The topmost layer comprises high-density foam, while the middle layer has foam-top comfort support for the mattress to retain shape and withstand pressure. But especially pleasing is the Tencel removable cover with its breathable fabric, resulting in smooth airflow to lull you to sleep. 

C. No Springs, Only Foam

Its solid core layer prevents bending and doesn’t have springs since it’s a foam mattress. 

D. Antimicrobial Coating 

The brand has used an Ultra-Fresh antimicrobial coating to prevent bacterial growth so that you can sleep healthier while maintaining a hygienic environment. This is particularly beneficial for people having allergies or asthma. 

E. Adaptive Comfort Technology

People can get a sound sleep with its Adaptive Comfort technology supporting the body and joints to help you wake up refreshed. This 7 cm top layer reduces pain in the shoulders, neck, and back, and has moisture-wicking properties to make temperature adjustments. 

Dimensions And Thickness 

If you’ve liked what you read so far, consider getting this mattress for a comfortable sleeping experience. To help you make a more refined choice, here’s a list of its dimensions and thickness. 

Single: 250 mm thick and measures 915 x 1,880 mm

King Single: The king single measures 1,065 x 2,030 mm, having a thickness of 250 mm 

From the above dimensions, it’s pretty clear that the brand doesn’t make any alterations to the thickness to retain its integrity and deliver maximum comfort. The length and width change slightly with each variety, making it suitable for different bed types.

Bonus Features 

Yes, you read that right – this mattress comes with certain bonus features, such as a free trial period and long-term warranty, making it worth the investment. 

For starters, the brand offers a 10-year warranty (no strings attached) so that consumers can repair the mattress if there are issues like sagging. We have also made sure that there are no hidden charges, saving you the hassle of costly maintenance. 

But the best part is the 120-night free trial period, whereby consumers can use the mattress and test whether it’s suitable for cushioning the joints or relaxing the muscles. If you’re unsatisfied, it’s easy to return the product, and the company will pick it up promptly, without charging shipping fees. 

What’s more impressive is that you can return old mattresses to the company and it will donate them to charity instead of throwing them away. This is part of the brand’s policy to give back to the community and help Aussies in need. 

Other Mattresses Accessories 

If you’re slightly disappointed after using the Delta Sleep mattress, don’t return it just yet. We might be able to offer a solution and recommend that you read our review of the brand’s mattress topper

Mattress Topper

This mattress topper is available in all standard sizes, making it suitable for various mattresses while providing much-needed support from back pain. The brand website mentions that it helps people minimise body aches and improves the chances of deep sleep by 48%. 

We found that it features a 4 kg fibre-fill support which restores comfort and ensures that the mattress retains its shape even after heavy use. Plus, the high-density layers cushion the body, cradling your neck, spine, and shoulders. 

It also has a cotton outer layer that’s extremely soft to touch and doesn’t trap heat, guaranteeing a much calmer and cooler experience. But before purchasing, you can opt for the 30-day free trial period, following which you can return it for a full refund if it fails to have the desired effect. 

Is This The Right Mattress For You?

Considering all the features of the Delta Sleep mattress, we feel that it scores a 7 out of 10, thanks to its comfortable, soft, and antimicrobial layers. However, what might be a bit worrying for some is the absence of springs. While the foam construction retains its shape, it may lack the back support that heavier individuals need. 

But we think it shouldn’t be too much of an issue since you can install sturdy bases and use the mattress with different bed types or a mattress topper. It also maintains ideal sleep temperatures and cradles the pressure points so that you wake up feeling refreshed. 

We believe that it’s a suitable option for most people, and even more so for consumers on a budget, because you won’t find better products in this price range. 

Final Verdict

That’s all there is to know about the Delta Sleep mattress; hopefully, you can now decide whether it’s the sleep accessory you need. 

We loved the innovative construction that will provide respite during the scorching Australian summer while also trapping heat when the mercury falls. Also, if they can adjust to the foam support, lightweight and heavy sleepers will enjoy the optimum airflow and moisture-wicking nature for a comfortable experience. 

Go through our guide again if you’re in doubt, and we’re sure you’ll make the right call.
