The Peace Lily mattress is for anyone that’s concerned about the environmental impact of their mattress and the chemicals they might be bedding down with. The Peace Lily is a natural, cleaner, eco-friendly choice, which seems to be the main reason Aussie sleepers choose it.
You might also choose it if you’re after a supportive, supple and springy sleeping surface that provides excellent pressure relief. It’s got the widest range of sizes of any mattress we’ve reviewed, including long single, king single and super king. This means it suits a wide range of sleepers, including children.
Latex isn’t known for its ability to reduce partner disturbance so shift workers or particularly wriggly sleepers might need to look elsewhere.
Hot sleepers, people who have particularly wriggly co-sleepers or people who need extra back support will find a lot to enjoy in the Emma Diamond mattress. With prices starting from $2,499 this is definitely more a master bedroom mattress than a guest or kid’s one.
Ali reckons side and back sleepers who prefer a medium to firm mattress will love the Emma Diamond. Because it combines the hugging feel of foam with the support of springs, weight is distributed evenly making it a good choice for anyone with back pain.
We highly recommend the Peace Lily mattress, especially for its natural, eco-friendly focus. A good choice for back and side sleepers, it offers a flippable firmness level between medium and firm and great pressure relief. Springy, it provides a lovely cushioning feel that gently moulds to your body. With a 25-year warranty - one of the longest we’ve seen - this is a durable, long-lasting mattress. (Be sure to read the warranty carefully to understand Peace Lily’s requirements around a suitable bed base to prevent moisture build-up.)
- Flippable firmness layers so you can choose a medium or firm feel.
- Huge range of sizes which is the widest of all mattresses we’ve reviewed.
- The clean, green naturalness of the mattress, including its sustainable manufacturing.
- That it’s handcrafted.
- Heavy to move, lift and turn.
- Returns policy isn’t great with customers in non-metro areas having to arrange a charity pick up or drop off.
- Delivery timeframes are vague.
Emma Diamond Hybrid Mattress
- The pressure relieving feel of the mattress that moulds to your body.
- Great suitability for hot sleepers.
- None to very little motion transfer.
- Very little off-gassing smell.
- Even though Emma says it’s medium-soft, most sleepers find it firm especially for the first few weeks. Our sleep tester Ali reckons it’s medium to firm.
- Lack of edge support makes the sleepable area of the mattress feel smaller.
- Rope in someone to help you manoeuvre the mattress as it’s quite heavy.
The Peace Lily mattress has 5 layers of natural, certified organic materials:
- A 100% certified organic cotton handmade cover that’s soft, cool and moisture wicking.
- 100% certified organic cotton wadding for a breathable, luxe-feeling cover.
- A medium 5cm layer of 100% natural rubber latex.
- A 100% natural rubber latex core layer.
- A firm 5cm layer of 100% natural rubber latex.
The layers are encased in 100% certified organic cotton, complete with a cotton tape edge that’s double stitched for durability. The layers are glued together with a natural latex glue that’s adhesive and chemical free. There are no toxins, polyurethane foams, chemical adhesives or nasties of any kind in a Peace Lily mattress. This is backed by international certification bodies, including eco-INSTITUT, OEKO-TEX and the Global Organic Textile Standard (GOTS).
Unlike the Emma Comfort, the Emma Diamond is a hybrid mattress. This means it’s got both foam and springs in 4 layers:
- Diamond Degree graphite foam which helps prevent heat build up and reduces partner disturbance.
- Adaptive comfort foam which is pressure relieving and responds as you move for all-night comfort.
- Pocket springs which increase air flow for a cool night’s sleep and minimise partner movements.
- HRX foam for extra support, especially for your back.
The Emma Diamond mattress has a removable and washable cover that’s 99% polyester and 1% elastane. The bottom of the cover is 100% polyester, while the base is 87% polyester and 13% polypropylene.
Peace Lily offers a 100-night free trial. However, they do ask you to try your mattress for at least 30 nights. This gives your body time to adjust and also allows the mattress to fully decompress. If it’s still not for you, you need to email Peace Lily and follow their instructions. The mattress needs to be in good condition and clean with no stains or tears, etc. (Pro tip: use a mattress protector!)
If Peace Lily agrees it’s in good condition, they’ll arrange a local partnered charity organisation to pick up your mattress for free. Once it’s been accepted and picked up by the charity, then Peace Lily will process your refund.
Some Aussie customers haven’t had the best returns process, especially those in more rural areas with no partnered organisations nearby. In some cases, customers have been left to arrange their own charity pick up / drop off. This has involved contacting local charities and attempting to wrestle a heavy latex mattress into their vehicle for drop off. Honestly, the returns process sounds like a hassle unless you live in an urban area.
The Peace Lily mattress comes with a great 25-year warranty. Latex mattresses tend to be more durable and longer lasting than other mattress types. However, you must use a bed base with your mattress, otherwise the warranty is void. It’s worth taking a read of the warranty to understand what Peace Lily defines as a suitable bed base.
All orders are dispatched within 1-2 business days of ordering and can take up to 15 business days for rural deliveries. Compared to Koala, who contact you with the day and time slot for delivery so you can make sure you’re home, Peace Lily is a bit more hands-off. Although you’ll get a tracking link emailed to you, they highly recommend you choose the authority to leave delivery option. Given the price of these mattresses, you might not feel comfortable having your mattress left outside your home.
Peace Lily courier drivers don’t bring your mattress inside your home or up any stairs so expect to haul the box around by yourself.
You’ve got 100 nights to try the Diamond. If it’s not right for you within this time, you can send it back. Emma asks that you give it at least 3-4 weeks before returning it. Returning it involves emailing them to arrange a free pick-up. This only applies to customers within their delivery area. Customers outside these areas (which aren’t listed on their website) need to take the mattress to their nearest drop off location, at their own time and expense. Once Emma has the mattress, they refund you within 14 days.
The Emma Diamond mattress has a 10-year warranty. This warranty covers sags or dips that are greater than 2.5cm, cracks or hollows in the foam, a mattress that doesn't fully inflate within 2 weeks, and damage to the cover (but not normal wear and tear). Claiming under the warranty involves emailing Emma with photos of the problem.
Emma offers free shipping, Australia-wide. Delivery timeframes vary massively. For in stock Diamond mattresses, you’re looking at 1-7 business days. But for those on backorder, it can be between 6 to 9 weeks. Unfortunately this seems to be where Emma struggles. There are some unhappy Aussies complaining that shipping has either been massively delayed (way beyond 6-7 weeks and into 4-6 months) or simply hasn’t turned up. Communications with Emma have been reduced to automated emails telling customers their order is delayed. It’s a shame that these shipping issues seem to be detracting from a great mattress.
