Any type of sleeper who’s after a supportive, cradling night’s sleep might appreciate the Emma Comfort - especially if you prefer a firmer mattress. With its great ability to minimise partner disturbance, it’s ideal for co-sleepers.
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.
Thousands (literally) of Aussie sleepers reckon the Emma Comfort mattress is a very good mattress. Even CHOICE, Australia’s leading consumer advocacy group, named it as their top scoring mattress for 2021. This all-foam mattress is supportive and pressure relieving for all sleepers and sleeping positions, although some sleepers do find it very firm.
From our personal experience, we feel the Emma Comfort mattress is one of the best budget mattress buys on the market, just bear in mind it suits sleepers who like it firm.
- The removable, washable cover which is the only one we’ve found.
- It’s pretty light for a mattress in a box so it's easy to move.
- The lack of partner disturbance.
- Some sleepers (including Daniel, our tester) found it very firm (and borderline hard).
- The buying process isn’t the most streamlined.
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 foam Emma Comfort mattress has 2 layers:
- A layer of Airgocell foam which is intended to minimise partner disturbance and is also moisture wicking to keep you cool and dry all night long.
- A layer of supportive HRX foam to help your hips, shoulders and spine stay in their correct alignment. It’s also breathable to promote good airflow.
The Emma Comfort mattress has a removable and washable cover that’s 99% polyester and 1% elastane. It’s also got a side cover (100% polyester) and a bottom cover (87% polyester and 13% polypropylene).
Emma seems less bothered about environmental concerns than other brands, with information tucked away in the ‘quality mark’ accordion. There we found that every layer complies with OEKO-TEX® Standard 10 which means it’s free of harmful substances.
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.
Emma offers you 100 nights to try the Comfort in your home. They do ask that you try it for at least 3-4 weeks before deciding if it’s right for you. If it’s not, simply email them to arrange a free pick-up - as long as you live within their delivery area. If you’re outside these areas (not listed on their website), you’ll need to take it to your nearest drop off location. Once it’s been picked up (or dropped off), Emma will refund you within 14 days.
You need to wrap it in its original plastic packaging ready for collection and it needs to be free from mould, dirt, stains, smells and bed bugs.
The Emma Comfort comes with a 10-year warranty that 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). To claim under the warranty, you need to email Emma with photos of the problem.
Shipping is free, Australia-wide. If you live in metro areas (Sydney, Melbourne, Brisbane and Adelaide) and order before 10am on a weekday, you should get it between 2 and 6pm that same day. Otherwise you can expect it within 2-7 business days. Tracking information is provided via SMS for metro areas, and via email for everywhere else.
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.

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.
