Artisan Luxury or Artisan Bespoke 002 for me?

Hi, I am 5'2" tall, weigh 7st 12lbs and want a very soft mattress to support my body weight naturally (I.e. Accommodate all joints without undue pressure in any area). I have an antique metal bed frame in the small double size with a half and half fixed wooden base. Which of the above two mattresses would you recommend for me? And what is the lead time from date of order placement?
With many thanks,
Veronica.
