Resilience Mattress not available in double bed size?

Good evening, I am a 20 stone 6 foot 1 guy and i sleep in a double bed 135 x 190.
I am very interested in the support your Resilience Mattresses offers the heavier sleeper, but notice there are no double bed size options for this mattress.
Would i get the same support from either the Hybrid 4 or Hybrid 5 mattresses?
Many Thanks
