I am 6'4" and weigh 100kg/16stone - I play rugby/basketball and go to the gym regularly (weights mainly). I have some back issues - mainly from sports and find my current mattress lacks support (6 Year old hybrid medium/Firm silent night 1400 spring hybrid). I wake most mornings with tight stiff muscles through my mid-back and my chiropractor thinks my mattress is to blame. I sleep on both my side and back so had been considering a firm tension mattress with a latex topper. I see you recommend firm tension for 17 stone upwards. Given I am not far off weight wise and with my back issues would firm e.g. Artisan Bespoke 004 be suitable for me?
