Comparable John Ryan mattress to Somnus Senza Jewel 5000

In my furnished rented flat I slept on a Somnus Senza Pocket Plus Jewel 5000 regular. Great mattress: Soft, responsive, supportive. Now that I’ve bought a flat I’m looking to buy something similar. Which John Ryan mattress would be comparable? I’m 5’9’’, 14 stone, side sleeper.
