Hi Alpharalpha,
Subject to first confirming that any retailer or manufacturer on the list that you wish to visit is completely transparent ( see this article ) and to making sure that any mattress you are considering meets the quality/value guidelines here … the better options or possibilities I’m aware of in and around the Tampa/ Clearwater/St Petersburg areas are listed in post #143 here .
Of those listed, these stores show that they offer latex products:
Pittsburgh Mattress Factory
Bartow Mattress Factory
Matter Brothers (might make latex mattresses – you’d have to phone)
Innomax
BodyRest has one latex model
Orlando Mattress Company
810Beds
Somnis Sleep
Bed Pros
Design Interiors
Better Back Store
Mattress Avenue
Phoenix
