Advice for heavy sleeper

Help on choosing the right mattress?
- 130 Kgs
- 187 cm
- Two main ways of sleeping: on the right hand side side and on the back
- When sleeping on the back : back pain sacro-illiac joint (RHS)
- When sleeping on the side: Shoulder pain and shoulder blade (Rhomboid) pain
- The mattress will be used on an electrical bed. This is important.
- room temperature is hot but sleeping with air conditioner all year
I was considering to buy a Tempur 22 cm (Sensation Deluxe Mattress) I understood that there is 21 cm which is based on the original mattress and 1 cm of soft padding
I am presently sleeping on a Simmons Beuuty rest I believe with springs/" title="pocket spring">pocket spring and a soft padding at the top.
So I was looking for your advice to buy probably some type of memory foam / latex type of mattress. Or a combination of that.
Do I go hybrid?
I was looking at your heavy sleepers mattresses but I am a bit scared that the 5 cm latex or 7.5 cm laygel topper would not provide sufficient cushioning.
What do you think?
If I buy your resilience mattresses and an additional topper. Can I swap the top when need be?
What I try to increase either the latex or laygel size to provide additional cushion?
 
I just wrote a previous post about heavy sleeper.
I forgot to mention that I am also willing to purchase the Bespoke 002.
What I am scared of is not to have enough cushion. And this is why I am considering latex /memory foam.
Which is best in your opinion.
Finally, can you use electrical bedding with any of your mattresses, included pocket springs?
