Hi Mittb,
I would agree and even though my knowledge of the UK market is very limited … based on what I have seen John Ryan beds would certainly be among my top choices.
You certainly have some good options to choose from including pocket coils with natural fibers, pocket coil latex hybrids, and all latex mattresses but the choice between each of them would really be a preference choice rather than a “better/worse” choice and would depend on which one your testing indicated was the best “match” for you. There is also more information about latex/pocket coil hybrids vs all latex mattresses in post #13 here and the posts it links to.
