Product is OK. Customer Service and communication woeful. I bought a mattress well in advance of a move into a new property. I called rather than buying online and confirmed that they could deliver on a specific date a number of weeks in advance. I was told no problem. Miscommunication started then. I was bombaded with messages to say "on… Read more

it's way", "we have your parcel". Clearly not. When the day came for move, no sign of the mattress and no communication. About a week later I received a"sorry we are out of stock". Err, I bought and paid for this, so stock should have been put aside! A series of seriously patronising emails overflowing with platitudes "understanding my frustrations" followed. Two weeks later the mattress arrived. Simply not good enough.

Unfortunately the king mattress was about 7cm too small for my king bed frame. I waited 5 days for it to inflate but it didn’t. I sleep on the edge of the bed and I rolled off the side it provided no support unfortunately. I have initiated return process and the customer service has actually been seamless and amazing! But the mattress itself is absolutely terrible. Thin layer of memory foam and you can feel the springs all through the sides. Show details

The mattress is 7cm less width than Australian standard king Bed. The mattress is sunken on all sides. The filling is 5cms sagging on all sides. I have sent 6 emails stating that it is inferior quality. There is no point in my trialling it. If you sit anywhere near the side you slide onto the floor. the I am lucky to have an alternative mattress… Read more

to sleep on. The Emma company do not have a phone number. I get the same email reply. Answers nothing just says they are busy. I paid nearly a 1000 dollars. It was supposed to be a Black Friday special. It is just rubbish. I will post again with a photo of the sagging. I am sick of no response or having to do so much work to get a reply. A robot response. You have to go to a lot of work producing photos. Rulers to prove it is sagging. Taking the cover off. To bad if you live alone or are incapacitated. It is such a shocking experience. Worst online shopping experience I have ever had.

A quality bargain – Have owned the Emma Sleep Comfort King Mattress for about six months now. It is so comfortable and supportive - it’s helped alleviate back and hip problems that were exacerbated by my previous mattress. I am now consistently getting 7 hours sleep, where as before I would usually get around 4 before waking up. The mattress has maintained its… Read more ·  1

So comfortable! We love it! – We love this mattress. We bought it to replace the mattress in our caravan and every time we sleep on it, it becomes even more comfortable. We’ve found that we sleep better on this mattress than the one we have in our house and are planning to buy another one. I love that when my husband rolls over or has to get out of bed, I don’t feel the mattress move at all. Show details ·  1

I’m very disappointed with my Emma Comfort Adapt mattress. The king size I purchased is noticeably smaller than my king bed frame, which was the first issue. I tried several times to return the mattress, but customer service refused, insisting I… Read more

continue using it for a few more months to see if it would ‘settle.’ Unfortunately, the mattress has now started sagging, and because the 150‑day trial period has passed, I have no choice but to keep it. Overall, this has been a frustrating experience and I cannot recommend it.

 Follow-up  · After multiple email exchanges with Emma regarding my earlier concerns, I want to provide an update. Emma ultimately agreed to replace the mattress, which I appreciate and view as a positive step in handling the situation. However, given my experience so far, I chose not to accept a replacement and instead requested a return and refund. To Emma’s… Read more

So disappointed. Have 2 Emma mattresses in the family. Upgraded to a king. I was told that I can't order the comfort foam layer until my mattress arrives. Waited for it to arrive and ordered one straight away. Was told it will take 1-3 days to arrive. 3 days pass and nothing. I follow up and I was told 'good news your order has been placed'....… Read more

But then that they out of stock and none will be arriving for months. But not to worry- i get 14 days of a sleep trial to add on after it arrives. I wasn't happy as I was lied to when I was told my comfort foam layer was sent. And also what am I to do with a mattress I can't use for months? A 14 days sleep trial is also not enough. So I return the mattress. It's taking over 3 weeks to be collected (actually I think it is 6). So I have a king mattress sitting here that I have to somehow make sure stays spotless. And a massive box to discard. On the plus side I got a ikea matress and omg it is so much better (and cheaper). You can sleep at the ends so don't lose space. Plus it isn't hot. We still have 2 Emma beds in the house but after this time, I wouldn't waste a cent on another one.

No lumps in this King Comfort mattress! – This is my second Emma mattress, the first being a single Original Emma. I like the single mattress and the Comfort King mattress. There are no lumps, bumps or edges anywhere. Just foam. It is not as firm in the middle as the single Original mattress and it feels fine. My wife likes it (she suffers from back pain); I was a little worried it might… Read more ·  1

not be right for her. She doesn't like the soft edge when she sits to get into bed. Apart from that, she likes it. I like the firmer middle, hips are supported comfortably. A quirky thing is, if you sit on the mattress where is goes from less to more firmness, you tend to lean over a little. We both sleep well on the Comfort mattress, I had occasional neck issues on our previous mattress (not an Emma mattress). The Original foam mattress wasn't hot last summer so I'm not expecting the King Comfort to be either (better not). It's too early to comment on durability; the single Original, over 12mths, hasn't shown any weakness. Perhaps I'll be able to add to this review in the future.

Took some getting used to – The initial unboxing was a bit concerning - the mattress was left, flat on the ground and after 48hours of resting still had corners which were sunken in and not expanding. Emma were quick to respond to my queries and were happy to start the return process, however I honestly couldn’t be bothered. Left it longer and the corners started to take… Read more ·  1

shape.

Initial impressions were “meh, it’s fine”. Our last mattress was a very firm Avatar which I loved. However we were moving up from a queen.

I like a firm bed and my husband softer - so this was a decent compromise.

It took a couple of weeks for us to really start finding it exceptionally comfortable!

I found that my pins and needles from shoulder compression as a side sleeper disappeared. My husband no longer complained about the mattress being too hard.

Fast forward a year - and I absolutely love our Emma Mattress! Well priced and very comfortable. Love being able to remove the mattress cover for washing - so bloody handy after having the 8 year old vomit through sheets, mattress protector and down to the mattress cover. Would never buy a mattress without a removable cover.

The only real negative thing I’d have to add would be the fact that it feels quite soft right on the edges - so when you’re sitting on the edge you sink quite a lot. However when laying down and near the edge, even weight distribution seems to avoid this.

This is a quick review of the customer service received from Emma - we haven't had a chance to try the mattress out yet. Our experience with Emma was extremely good - out contact at Emma - Evan - answered all our questions before putting the order in and continued to help us throughout the order process and ensured that we received our mattress on time. He is a credit to Emma. Show details ·  1

It is not suitable for someone with any joint issues, it is so hard and cold! I reported this issue immediately, wanted to return it. Instead they sent a thin piece of foam “to make it softer” it seemed to improve a bit. It is still the worst mattress I have ever wasted money on. I would definitely NOT RECOMMEND Show details

Worst service – I ordered a King mattress and protector. Two months later I revive a Queen mattress and Double protector. There is no phone number or email to contact Emma Sleep, so I had to communicate with a Bot. I didn’t get a response and had to start conversing with the Bot from scratch for three weeks until I finally got an email. I was then asked to send… Read more

in photos proving I had the wrong order! Eight weeks later nothing and I heard nothing further until I fortunately got a call from Emma Sleep that I could pick up (they don’t leave a number so you can’t call back if you miss the call). I had to be forceful and threaten legal action until they finally agreed to issue a refund. I then had to arrange pick up of the items myself. Absolutely crap service.

Great value and quality, very firm feel – Supportive and zero partner disturbance, however, it is very firm. I've generally been a firm mattress guy but with no pillow top it does feel very firm particularly when on my side. Credit to Emma though, I've made contact to 'complain' and they are sending a complimentary soft topper so I'll see how that goes once it arrives. Show details ·  2

King Size EMMA! – This mattress was so easy to put on the bed. Since having the mattress, my back pain has reduced so much I don’t need to take medication to cover my pain before going to bed.
