I believe i have mate, got it a couple of years ago because the other half believed it was very good. My first thoughts were it was a hard mattress but I soon got used to it. I have no issues sleeping on it. Partners daughter in oz bought one of those Emma memory foam mattresses as she thought they would be as good as simba. She sent that one back.
Anyway you don't have to take anyone's word as they offer a 100-night trial or return I believe.
