Latex mattress with medium feel

Hello, Ive been looking for a mattress, after a lot of research have considered the Simba but the Fusion 3 looks better even though it is more expensive. Both me and my husband suffer with the aches and pains of a typical 60 year old and I am fidgeting all through the night and also get a bit hot ( probably why I,m waking up ) I weigh 11 stone and my husband is about 12 stone. We have a good solid divan base but the mattress is getting old and I feel after trying in the showrooms memory foam mattress seemed ok but after research are too hot and Simba is synthetic rather than natural latex like the Fusion range , can you advise please
