Hi ShellyS,
Welcome to the Mattress Forum! :cheer:
The better options or possibilities I’m aware of in the general Ft Lauderdale / Miami / Palm Beach Gardens areas that would also include Delray Beach (subject to making sure that any mattress you are considering meets your criteria and the quality/value guidelines here) are listed in post #2 here.
The better options and possibilities I’m aware of in the Stuart / West Palm Beach areas are listed in post #2 here.
Fox Mattress is a member of this site which means that I think very highly of them and that I believe that they compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency.
I look forward to hearing about what you end up purchasing.
