Help to choose a supportive mattress that offers a luxurious feel

My wife and I have slept on a vispring elite mattress (firm/medium) on a slatted bed for over 10 years and think it’s time to replace. We want to purchase a divan and mattress but I am quite tall and heavy, 6ft 2” and 16-17 stone, my wife is 5ft 6” and about 11 stone.I have been looking at the artisan naturals and artisan luxury but I’m wondering if they would be too soft for my size, we want a mattress that is supportive but offers that luxurious feel.
Thanks
Paul
