Hi zeff,
I would pass on the Zenbody even though it’s a nicer version than the Embody in the US (it’s all latex) but the latex is still lower quality and mostly synthetic.
You are fortunate though because there are more factory direct mattress manufacturers in and around Montreal (within about 100K) than any other city in North America that I know of and almost all of them produce latex mattresses as well as every other style and combination as well. There is a list in post #276 here (I added the cities so it would be easier to scan).
You have some great choices near you and I certainly wouldn’t be considering a major brand or a chain store (see the mattress shopping guidelines here) with so many high quality choices so close to you
