I've searched, and there are lots of threads about mattresses but I can't find any references to this brand.
It's a mattress-in-a-box one, memory foam with adjustable firmness made up of three layers you can put on in a different order.
What appeals is that it's very green and doesn't have chemical fire retardants added.
Our current mattress* is sprung and I don't have any experience of memory foam.
We are stupidly busy and live a stupid distance from the sort of shop where you can go and lie on lots of mattresses to try them out so I fear we are going to have to do online.
*our current mattress is also 20 years old and DH claims it's fine.....
