Sleep Republic ES Mattress

Purchase and delivery

How do I buy the Sleep Republic ES Mattress?

Like other products in the Sleep Republic range, the ES Mattress can be purchased online via the Sleep Republic website. The order process is quick and user-friendly, and delivery is free Australia-wide.

Delivery to metro areas typically takes 1–3 business days. For regional and remote areas, delivery timeframes may extend to 3–7 business days depending on location.

The mattress arrives compressed in a box and includes an information card outlining key setup and care instructions. We recommend allowing 24 hours for the mattress to decompress fully before use.

Aesthetics and Presentation

What does it look like in real life?

The Sleep Republic ES Mattress looks clean and modern. It features a soft, smooth Tencel™ cover with a white and charcoal colour scheme. The side panels are made from breathable mesh-style fabric (similar to sports apparel), which adds a touch of performance styling while promoting airflow.

Sleep Republic ES Mattress

A Sleep Republic brand tag is stitched onto the side of the mattress. There are also two side handles on each side, stitched horizontally and spaced well for grip. These handles feel secure and sturdy – helpful for lifting or rotating the mattress.

The overall profile stands at 28cm high, which is consistent with most standard fitted sheets.

Mattress construction

What’s inside the Sleep Republic ES Mattress?

The Sleep Republic ES Mattress combines high-quality foams with a sophisticated pocket spring system:

1. Tencel™ Fabric Cover

The soft, breathable cover helps regulate sleep temperature and provides a cool, comfortable surface for sleeping.

Sleep Republic ES Mattress

2. FirmCore™ High-Density Foam

This comfort layer offers gentle contouring and pressure relief without compromising support. It’s lightweight, breathable, and designed to cushion the body evenly.

3-Zone High-Definition Pocket Springs

The support core consists of up to 2,500 individually wrapped springs, divided into three ergonomic zones:

  • Head & Shoulder Zone – softer springs for light cradling

  • Back & Hip Zone – firmer springs for spinal support

  • Leg & Foot Zone – softer springs for pressure relief

This zoning helps maintain healthy spinal alignment and promotes comfort in all sleep positions.

4. Dynamic Edge Support

The perimeter of the mattress includes higher-tension springs, helping to prevent sagging and enhance usable sleeping surface area.

Comfort and support

What’s it like to sleep on the Sleep Republic ES Mattress?

The top surface of the mattress feels smooth, soft, and breathable. The quality of this fabric is impressive in context of price.

The mattress absorbed body weight smoothly and evenly. Furthermore, it cradled the shoulders and legs gently while keeping the hips well supported. Essentially, the mattress offers a very nice balance of comfort and support.

All of our expert reviewers agreed on the firmness level, with a consensus rating of 7.5 / 10 on the firmness scale (with 10 being the firmest). We would classify this mattress as ‘medium-firm’.

Firmness rating

This firmness profile should suit a wide range of sleepers, including side, back, and stomach sleepers. Heavier individuals may find the mattress slightly softer due to deeper sink, but it should still offer solid support and comfort.

Please note that our firmness ratings are just a guide and they do not necessarily relate to comfort.

Furthermore, our firmness ratings are assigned based on Bedbuyer’s testing process and these may differ from firmness ratings given by individual companies. Mattress firmness will also vary depending on the type of bed base used.

We tested the Sleep Republic ES Mattress on the Chiropedic Bed Base which is a good quality bed base with rigid slats.

The Sleep Republic ES Mattress responds well to normal sleep movements and we rated its responsiveness as optimal. In basic terms, this means that changing sleep positions (and intimate activities) shouldn’t require much effort.

Responsiveness

Please note that our responsiveness scales are just a guide and preferred responsiveness levels will vary between individuals. It’s worth noting also that innerspring mattresses are generally more responsive than foam mattresses.

The finer details

What else should I know?

The build quality of the Sleep Republic ES Mattress is excellent, particularly at this price point. It feels well-made and the materials appear durable.

Motion isolation was admirable. Partner disturbance was low during testing, and any movement from one side of the bed was not overly noticeable on the other.

With that said, motion transfer may vary. A larger mattress (e.g. king size) will usually involve lower amounts of motion transfer. Partner disturbance will also depend on the size of the occupants of the bed.

The mattress absorbed body weight smoothly and evenly.

The mattress feels stable and supportive across the entire surface, with no roll-off sensation near the edge – a good indicator of effective edge support.

We didn’t detect any abnormal heat retention during our testing. The breathable Tencel™ cover and open spring system allowed for good airflow, which should help prevent the mattress from sleeping hot.

Keep in mind though that sleep temperature can be complex and involves many factors (e.g. type of mattress, pillow, clothing, sheets, room temperature, humidity, medical conditions, occupants of the bed etc).

Furthermore, soft mattresses tend to be warmer (than firm mattresses) as the thick layers of foam can trap heat during sleep.

The mattress includes four horizontal side handles (two per side), which are stitched securely and provide ample grip.

Bed base compatibility

What type of bed base should I use?

As with most mattresses, we recommend the Sleep Republic ES Mattress to be used on a bed base with flat panel slats such as the Koala Paddington Bed Base.

A bed base with solid slats such as the Chiropedic Bed Base, would also be very suitable.

Koala Paddington Bed Base

We would advise against using a bed base with flexible (posture) slats as this type of base may not provide adequate support. Ultimately, the use of an unsupportive mattress foundation will void the mattress warranty.

We don’t recommend the Sleep Republic ES Mattress be used with an adjustable (electric) bed base. as this may cause damage to the mattress components. Here is our full list of mattresses that are compatible with an adjustable bed base.

It’s worth noting here that mattress firmness, performance, and durability will vary with different bed bases.

Trial period and warranty

What happens if I don’t like it?

The Sleep Republic ES Mattress comes with a 150 night trial period, which is superior to a typical trial period (of 100 nights) in the online mattress market.

Sleep Republic does ask that you try the mattress for at least 14 days to allow your body to adjust to the new mattress.

This trial period means that you can return the mattress for a refund if you are not satisfied. Conditions do apply though, for example regional and rural customers may be charged a return shipping fee which will be deducted from your refund.

This mattress also comes with a 12 year warranty to cover any faulty materials or workmanship. This is also a superior warranty period compared with similarly priced competitors.

Available sizes

What size options are available?

This mattress is available in 3 sizes (king, queen, and double) so it should accommodate most sleeping arrangements.

The graphic below includes all of Australia’s standard bed (mattress) sizes in 2025. Again please note that the Sleep Republic ES Mattress is available in 3 of these sizes.

Competitor Comparison

How does the Sleep Republic ES Mattress compare to other top mattresses?

Here’s how it stacks up against some of its main competitors in the Australian market:

vs. Sleeping Duck Mattress

  • Firmness options: Sleeping Duck offers adjustable firmness via interchangeable foam layers, while Sleep Republic ES has a fixed medium-firm feel.

  • Support system: Sleeping Duck uses a multi-zone spring base with foam layers on top. Sleep Republic ES uses a high-definition 3-zone pocket spring system with responsive comfort foam.

  • Price: Sleeping Duck (queen) starts at $1,649, significantly more than the cost of the Sleep Republic ES Mattress.

  • Edge support: Both offer strong edge support, but Sleep Republic’s use of firmer perimeter springs gives it an edge at this price point.

  • Trial & warranty: Sleep Republic – 150 night trial, 12 year warranty. Sleeping Duck – 100-night trial and 10 year warranty.

vs. Koala Mattress

  • Construction: Koala is an all-foam mattress with adjustable firmness, while Sleep Republic ES is a hybrid with springs and foam.

  • Feel: Koala may feel more spongy and absorbent; Sleep Republic ES offers more bounce and airflow due to the spring unit.

  • Motion isolation: Koala performs very well here. Sleep Republic ES also minimises partner disturbance, but not quite to the same extent due to its spring system.

  • Edge support: Sleep Republic ES provides better edge support with dedicated perimeter springs.

  • Price: Depending on sales, both mattresses are similar in price.

Koala Mattress

vs. Emma Comfort Mattress

  • Firmness: Emma Comfort has a single medium feel (around 5/10); Sleep Republic ES is firmer (7.5/10).

  • Motion isolation: Emma Comfort performs very well thanks to its all-foam design. Sleep Republic ES offers a bit more bounce and airflow.

  • Construction: Emma Comfort is all-foam; Sleep Republic ES uses zoned pocket springs for improved spinal alignment and airflow.

  • Price: Depending on sales, both mattresses are similar in price.

  • Trial & warranty: Sleep Republic – 150 night trial, 12 year warranty. Emma – 150 night trial and 10 year warranty.

Customer feedback

What are real Aussie customers saying?

As of August 2025, the Sleep Republic ES Mattress is still relatively new to market and broad-based customer feedback is still emerging. That said, early impressions from customers and Bedbuyer’s expert team have been very positive – particularly in terms of support, edge strength, and overall value.

We’ll continue to monitor consumer feedback and update this section as more verified reviews become available.
