Looking to purchase a medium feel hand side stitched mattress

Dear sirs,
We are in need of initially a mattress, but maybe a full bed, can you please assist?
We currently have a bed purchased ~15yrs ago from Furnitureland, although I believe the company as it was no longer exists. It is from the Rendezvous range in the Savoy style. It is a 1450 pocket sprung, medium firmness, hand-stitched sides, with edge-sprung base.
It has lasted us well and we are very pleased with it.
Ideally, we would like something similar, or better.
Can you please recommend for us?
Many thanks.
