Purchase and delivery

How do I buy the Peace Lily Cot Mattress?

The Peace Lily Cot Mattress can be purchased online through the official Peace Lily website. Ordering is straightforward, and free shipping is available to most metro, regional, and rural locations throughout Australia.

Delivery times vary depending on your location. Metro customers generally receive their mattress within 1–5 business days of dispatch, regional deliveries typically arrive within 4–10 business days, and rural locations may take between 6–14 business days. Some regional and remote locations may also attract a delivery surcharge, depending on the delivery address.

Our cot mattress arrived in excellent condition inside a sturdy cardboard box. Unlike many adult mattresses, it is not compressed or vacuum packed, allowing it to retain its shape during transport. Inside the box, the mattress was protected by a neat fabric storage sleeve, which gave the overall presentation a premium feel.

At around 10kg, the mattress is easy to handle and unpack. Simply remove it from the packaging and place it directly into your cot – there is no waiting period for the mattress to expand before use.

As part of our standard testing process, we carefully inspected the mattress upon arrival before commencing our assessment.

Aesthetics and presentation

What does it look like in real life?

The Peace Lily Cot Mattress has a clean, natural appearance that suits modern nurseries particularly well. Its cream organic cotton cover gives it a premium look, while the neat quilting, quality stitching, and piped edges create a tidy, well-finished presentation.

At 10cm high, it has a slim profile that sits neatly within a standard Australian cot.

A thoughtful design feature is the embroidered labels on each sleeping surface. One side is clearly marked “Infant” and the other “Toddler”, making it quick and easy for parents to identify the correct side as their child grows.

Overall, the mattress presents as a high-quality product with excellent attention to detail and a finish that reflects its premium positioning.

Mattress construction

What’s inside the Peace Lily Cot Mattress?

The Peace Lily Cot Mattress features a thoughtfully designed all-latex construction using premium natural materials throughout.

Its dual-sided design allows the mattress to adapt as your child grows, with a firmer infant side and a slightly softer toddler side, while maintaining excellent breathability, durability, and support.

1. Certified Organic Cotton Cover

The outer cover is made from three layers of certified organic cotton, consisting of a knitted outer fabric, organic cotton wadding, and an organic cotton woven backing. The cover feels soft and breathable while remaining free from synthetic materials.

2. Infant Latex Layer

One side of the mattress features a 5cm layer of 100% regenerative natural latex designed specifically for infants. This firmer sleep surface provides the flat, supportive feel recommended for younger babies while remaining naturally breathable.

3. Toddler Latex Layer

The opposite side contains a second 5cm layer of regenerative natural latex with a slightly softer, medium-firm feel. This side is designed to provide additional comfort and pressure relief as children become more active during their toddler years, while still maintaining excellent spinal support.

4. Bonded Construction

The cotton cover is bonded directly to the latex core using a natural latex adhesive. This anti-pooling construction helps maintain a taut, flat sleeping surface and contributes to the mattress’s long-term durability.

Firmness adjustment

How does the dual-sided design work?

The Peace Lily Cot Mattress features a dual-sided design that allows it to grow with your child. Rather than requiring a new mattress as your child gets older, you simply flip the mattress over to use the appropriate sleeping surface.

The infant side provides a firmer feel that is designed to meet the needs of younger babies (e.g. 6 to 18 months), offering a flat and supportive sleep surface. Once your child reaches the appropriate age (e.g. 18 months onwards), the mattress can be flipped to the toddler side, which has a slightly softer, medium-firm feel for added comfort while still providing excellent support.

A nice practical touch is the embroidered “Infant” and “Toddler” labels on each side of the mattress, making it quick and easy to identify which side should be facing up. The process takes only a few moments and is a simple way to extend the usable life of the mattress as your child grows.

Comfort and support

What’s it like to sleep on the Peace Lily Cot Mattress?

Before discussing the two sleeping surfaces, it’s worth mentioning the quality of the organic cotton cover. It feels soft, breathable, and quite premium, creating a comfortable sleep surface that complements the natural latex core.

Infant Side

The infant side of the Peace Lily Cot Mattress provides a firm, supportive sleeping surface that is appropriate for younger babies. While it has a reassuringly firm feel, there is still a modest level of comfort thanks to the natural latex.

By majority vote, we rated the infant side as 8 / 10 on the firmness scale, with 10 being the firmest.

Infant Side

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.

Toddler Side

The toddler side offers a slightly softer feel while still maintaining excellent overall support. It provides a little more cushioning and comfort than the infant side, making it well suited to growing toddlers without compromising the supportive characteristics of the mattress.

By majority vote, we rated the toddler side as 7 / 10 on the firmness scale, with 10 being the firmest.

Toddler Side

Overall spinal support is excellent across both sleeping surfaces. Despite its relatively slim 10cm profile, the natural latex core feels robust and highly supportive, providing a stable sleeping surface that should comfortably support children throughout their infant and toddler years.

The natural latex also gives the mattress a pleasantly responsive feel. It isn’t excessively bouncy, but it responds well to normal sleep movements without feeling restrictive. To this point, we rated the responsiveness of the Peace Lily Cot Mattress in the optimal zone.

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 Peace Lily Cot Mattress is exceptionally well made. The stitching is neat and consistent, the materials feel genuinely premium, and the overall finish reflects a high level of craftsmanship.

Despite its relatively simple construction, it feels robust and durable, giving confidence that it should comfortably withstand many years of everyday use.

At approximately 10kg, the mattress is also easy to handle. Most parents should have no trouble lifting, rotating, or flipping it between the infant and toddler sides without assistance, making the dual-sided design practical for everyday use.

Edge support is excellent on both sides of the mattress. The natural latex maintains its shape right through to the perimeter, with very little compression around the edges. This creates a consistently supportive sleep surface across the entire mattress and helps maximise the usable sleeping area.

One of the standout aspects of the Peace Lily Cot Mattress is its impressive range of certifications and natural materials. The latex is certified to the Regenerative Latex Standard (RLS), providing full traceability from plantation to finished product, and is sourced from Regenagri-certified farming practices that promote regenerative agriculture.

The mattress also has a partnership with Asthma Australia, complies with the AS/NZS 8811.1:2013 infant sleep surface firmness standard, and meets the ACCC’s 2024 infant product information requirements.

Collectively, these certifications provide an additional level of confidence regarding the mattress’s materials, safety, and environmental credentials.

Other details

The Peace Lily Cot Mattress is designed to fit standard Australian cots that accommodate a standard 130cm × 69cm cot mattress. As with any cot mattress, achieving a snug fit within the cot is essential for both safety and performance.

When the mattress is correctly positioned in the centre of the cot, the gap between the mattress and the cot sides should not exceed 2cm. If the mattress is pushed fully to one side, the gap on the opposite side should not exceed 4cm. These recommendations align with the Australian/New Zealand Standard AS/NZS 2172 for household cots.

The mattress should always be used on a firm, flat cot base in good condition. It should sit evenly within the cot without bowing or leaving excessive gaps around the perimeter.

Finally, remember to use the appropriate side of the mattress for your child’s stage of development. The embroidered “Infant” and “Toddler” labels make it quick and easy to identify the correct sleeping surface before placing the mattress in the cot.

Trial period and warranty

What happens if I don’t like it?

The Peace Lily Cot Mattress comes with a 100-night trial period, giving parents plenty of time to assess the mattress at home and ensure it suits their child’s needs. Peace Lily recommends using the mattress for at least 30 days before making a decision, allowing sufficient time to properly experience its comfort and support.

If you aren’t satisfied with the product, Peace Lily’s customer service team will assist with the return process. Where possible, returned mattresses are donated to charity rather than sent to landfill, giving them a second life while helping local communities. Please note that the trial is subject to Peace Lily’s terms and conditions.

The Peace Lily Cot Mattress is backed by a 10-year limited warranty, reflecting the company’s confidence in the durability of its regenerative natural latex construction. The warranty covers manufacturing defects and faulty workmanship, subject to the company’s warranty terms and conditions.

As with any mattress purchase, we recommend reviewing these terms before buying so you understand the coverage and any applicable exclusions.

Available sizes

What size options are available?

The Peace Lily Cot Mattress is available in one standard Australian cot mattress size – 130cm × 69cm. This size is designed to fit standard Australian cots that accommodate a standard cot mattress.

As this is the standard cot mattress size used throughout Australia, it should be suitable for most infant and toddler sleeping arrangements. As always, we recommend confirming your cot’s internal dimensions before purchasing to ensure the mattress provides a snug and safe fit.

Price

How much does the Peace Lily Cot Mattress cost?

The Peace Lily Cot Mattress is available in one standard cot size and is priced at $699. Unlike many mattress brands, Peace Lily does not run frequent sales or promotional discounts, so this is generally the standard year-round retail price.

While it sits at the premium end of the cot mattress market, the use of 100% regenerative natural latex, certified organic cotton, dual-sided infant and toddler firmness, and a 10-year warranty help justify the higher price point.

For parents looking for a long-lasting cot mattress made from natural materials, it represents good value despite the higher initial investment.

Did you know?

Peace Lily specialises in natural latex bedding

Peace Lily also offers two other mattresses within its range.

The original Peace Lily Latex Mattress remains the company’s flagship all-latex mattress, while the Peace Lily Hybrid Mattress combines natural latex with a pocket spring support system to provide a slightly different feel.

Both mattresses continue the brand’s focus on premium natural materials and sustainable manufacturing.

Final verdict

Is this the right mattress for you?

The Peace Lily Cot Mattress is a premium cot mattress that combines high-quality natural materials with a thoughtful dual-sided design.

The infant and toddler sleeping surfaces provide excellent support as your child grows, while the regenerative natural latex and certified organic cotton contribute to a comfortable and breathable sleep environment.

We were also impressed by the extensive range of health, safety, and environmental certifications, which reinforce the quality of the materials and construction. While it sits at the premium end of the market, we believe the Peace Lily Cot Mattress is an excellent product and one of the best natural cot mattresses currently available in Australia.
