Onebed vs Emma Diamond Hybrid Mattress Comparison

Sleepers looking for a firm mattress that combines quality materials, including memory foam and latex, will love the Onebed Original. With flippable firmness levels, it provides a supportive, comfortable sleep that suits all sleeping styles. Effective at minimising partner disturbance, it’s great 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.

According to thousands of happy Aussie sleepers, the Onebed Original is very good. This quality latex, memory foam, and foam mattress offers customisable firmness from medium through to medium-firm and firm. Known for its support and firmness, the Onebed Original is also great at minimising partner disturbance and sleeping cool.

• The adjustable firmness levels, from medium through to medium-firm and firm.
• The removable, washable cover to keep things smelling sweet.
• Quality materials, including latex and memory foam.
• Thousands of happy Aussie sleepers.

• Lack of details, including shipping and basic stuff like weight.

• 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 Onebed Original mattress is an all-foam mattress with 3 layers:

1. A 4cm latex top layer for a cool, somewhat bouncy sleep.
2. A 4cm memory foam layer for cushioning support that moulds to your body, plus pressure relief.
3. A 17cm polyurethane foam layer for a stable, quality support base.

It’s also got a removable, washable polyester cover. All materials in the OneBed Original are certified free of harmful chemicals and other nasties by independent testing organisations.

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.

The Onebed Original comes with a 125-night trial. Onebed asks that you try it for at least 30 nights before returning it. If it’s not right for you, you can email them to arrange a free pick up. Once it’s been picked up, you’ll be fully refunded - within 30 days. Onebed also promises that it’ll be picked up within 30 days. So you could be looking at up to 60 days or around 2 months for your refund to be issued.

You have a 15-year warranty with a Onebed Original. This warranty covers any indentation that’s deeper than 2cm; a flaw that causes the foam or latex to split or crack; and failure of the mattress zipper or tearing of the outer cover. If the cover develops a fault, only the cover is repaired or replaced. The warranty is void if you don’t use a suitable bed base so don’t use the mattress on the floor.

No shipping information is provided beyond it being ‘fast and free’.

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.
