Mattress Type help

Hello, typically we have gone for a firm mattress and really like your Artisan Tailored Pocket 2000 but at less than 11 stone each will this feel too soft?

Also, I would rather put funds into a better mattress than replacing the bed base which is still perfectly fine, this has a solid ventilated base and I just wanted to confirm this will be okay with the Artisan range (or suggested alternative).

Can you advise the best mattress type please for us?
