Has anyone tried an Emma Sleep Mattress? Or Koala? Ecosa?
I got a quote from Harvey Norman (urgh) for a King Koli mattress and tested it. It felt nice, but if I can avoid giving them money I will happily do so. But online ones and online reviews are hard to trust.
Many of them have a trial policy, where you can return within x days if you don’t like it. So it’s pretty low risk. It’s a different feel to a sprung mattress, which will come down to personal preference and if you have any back or body issues. I personally like the foam mattresses, have a koala one and so far it is fine. Although from what people say it seems sleeping duck ones are a bit better.
I've got a Sleeping Duck mattress and it's the best one I've ever owned. You can easily change the top foam layer from soft/medium/firm if you order a mattress that's not the right firmness for you. And you can return it for refund if it's not right for you at all (100 day trial currently). So basically no risk to you to try it out.
