Thank you for your enquiry.  The firmness will be very similar, the 100% natural is ever so slightly more responsive and a little bit softer. It all depends on how sensitive you are. Some people can feel the difference others state there's little difference.

With 100% natural latex such as our Fusion 3 in our latex range, they are the highest quality latex blends you can get. If budget is your main driver then we offer the 80% natural blend to try and meet this price point. The 80% latex blend is still far higher than the average 'Natural Latex mattress' in retailers which at most is usually 60% natural latex in our experience. Sometimes it's only 20%!!

Hope that helps, if you would like any further information please do not hesitate to contact the office on 0161 437 4419.

Kind Regards
