Hi danielp,
Thanks for sharing your comments and feedback about Dixie Foam in the other topic you were posting in here.
I switched your last post to a new topic because it was beginning to drift outside the scope of the original topic you were posting in.
The better options or possibilities I’m aware of in and around the Vancouver area (subject to making sure that any mattress you are considering meet your criteria and the quality/value guidelines here) are listed in post #2 here.
While some of them would probably carry a 6" latex mattress … I don’t know if any of them use zoned latex so you will probably need to check their websites or make a few phone calls to find out which if any of them make a mattress that would “approximate” the Dixie Foam mattress you used to own.
