Ecosa vs Emma Diamond Hybrid Mattress Comparison

Sleepers who want to adjust their firmness level between medium and firm will love the Ecosa mattress, as will anyone who wants the support of memory foam. With its lack of partner disturbance, it’s good for co-sleepers and the midrange price makes it a good guest or child option.

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.

The Ecosa mattress is a great mattress in a box. This is especially because of the customisation it offers. With flippable firmness layers, you can choose whether it feels medium, medium-firm or firm. It’s also got a waterproof and dust mite resistant cover that you can remove and wash for easy care. Plus, Ecosa gets bonus points for being Australia’s first certified carbon neutral mattress company.

• Wide range of sizes, from single all the way up to super king.
• Flippable firmness layers so you can choose from anywhere from medium to firm.
• Proudly Aussie company that’s certified carbon neutral.
• Removable and washable cover.

‍

• No handles (although the Ecosa mattress doesn’t need rotating or flipping).
• Some sleepers find it too firm, even on the medium feel.
• Returns can be hit and miss.

• 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 Ecosa mattress is an all foam mattress, with 3 layers:

1. G-7 gel memory foam that’s designed to be supportive and cooling.
2. ECO-Tex memory foam with an open cell design for breathability.
3. Ergonomic support foam for correct spinal alignment and to reduce partner movements.

The Ecosa mattress has an inner cover that’s waterproof and also helps keep out dust mites.  All these layers are encased in a removable, washable cover that’s 40% Tencel and 60% poly.

All the materials in the Ecosa mattress, including the foams and covers, are certified free of harmful chemicals and other nasties.

Unlike the Emma Comfort, the Emma Diamond is a hybrid mattress. This means it’s got both foam and springs in 4 layers:

1. Diamond Degree graphite foam which helps prevent heat build up and reduces partner disturbance.
2. Adaptive comfort foam which is pressure relieving and responds as you move for all-night comfort.
3. Pocket springs which increase air flow for a cool night’s sleep and minimise partner movements.
4. 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.

You can try the Ecosa mattress for 100 nights. You do need to try it for a minimum of 14 nights before returning it. To arrange a return, you contact Ecosa via email, online chat or online form. Ecosa will then arrange a free pick up for you, through their charitable partners, like The Salvation Army. This can take up to 10 business days.

If you live outside cities, returns are a little trickier and Ecosa may ask you to return the mattress to your local pick up spot, at your own cost and time. Once the mattress has been picked up or dropped off, Ecosa will process your full refund. There are a few recent customers who have struggled with the returns process. Mainly this is long pick up times and being unable to get in touch with the Ecosa customer service team.

The Ecosa mattress comes with a 15-year warranty which covers visible dents that are deeper than 2cm; split or cracked foam; or a manufacturing defect of the cover. Ecosa is keen to promote that this mattress can sit happily on any firm, flat surface, including the floor.

But they do also point out that you need to stand the mattress regularly to breathe and ideally air and vacuum the area beneath the mattress. That’s because they won’t accept returns or warranty claims for mould or mould-related problems. This is much better the Noa mattress warranty that’s void if you don’t use a bed frame, although they state the mattresses can be used on the floor.

Like most mattresses in a box brands, Ecosa seems to be struggling with deliveries lately with lots of complaints about deliveries not turning up when they’re supposed to.

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.
