Hi picklepot,
The better options or possibilities I’m aware of in and around the Portland, OR area including Salem (subject to making sure that any mattress you are considering meets the quality/value guidelines here ) are listed in post #2 here . I did go through the list and update some of the information and add a few more stores.
As for latex on that list, initially I would phone these businesses and see if they have any items available that you may wish to try out:
Mulligan
Mattress Lot
Bedtime
Cotton Cloud – a few
Parklane. Few all latex and latex/memory foam. Not sure if can do custom latex products.
I don’t know if any of these stores will offer the specific style of customizable mattress you’re considering.
Those combinations certainly would “generally” be suitable for what you described, but I would still take the time for a detailed phone conversation before placing any order with SleepEZ.
