Bed guarantees, the Vi Spring Devonshire vs the Artisan Luxury?

The Artisan Luxury is classed as being like the Vi Spring Devonshire. The guarantee however differs (10 vs 30 years). What would you say about this? I like the idea of not having to buy another bed if it lasts for 30 years (I’m 62)! Will the Artisan be any good after 10 years?
