This mattress has far exceeded our expectations on comfort and support. We both suffer from back issues from time to time so it was important we had a good mattress. Having had Relyon before we were looking for a similar product to replace our old mattress. We both expected a settling in period to get used to it but this was not the case a perfect nights sleep from day one. Our only bug bear is it could do with handles at the end as well as the sides as its very heavy to turn around and being fairly deep too its hard to handle when you have got it half way round with nothing to hold onto.
