Sleep Republic ES Mattress Review
The Sleep Republic ES Mattress is an innerspring mattress designed to offer everyday comfort and targeted support. With high-definition pocket springs and premium foams, it delivers impressive value in a well-rounded sleep system.
The Sleep Republic ES Mattress also classifies as a true ‘hybrid’ mattress, meaning that it contains a combination of foam layers and springs in one cohesive unit – without a distinguishable pillow top.

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.
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.
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.
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.
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.
