Hi Alan,
I changed the title and created a new thread to make it easier for others in your area to find this thread 
You are fortunate in that there are several quality independent factory direct manufacturers near you. They are …
http://foxmattress.com/ Holly Hill, FL. They are a local factory direct manufacturer that makes all types of mattresses. I have had some great conversations with Rick the owner and he is exceptionally helpful and knowledgeable. They are also a member here which means that I believe they compete well with the best in the industry in terms of their quality, value, service, and transparency. They would be well worth a drive to Holly Hill to include them in your research.
http://www.orlandomattresscompany.com/ and http://atlasmattressfactory.com/ Lake Hamilton, FL. They are local manufacturers who are working in partnership and make a range of good quality mattresses. They generally make commercial mattresses for hotels and cruise liners but they also sell direct to customers at the Atlas Mattress showroom. They make traditional mattresses (innerspring/polyfoam using a wide range of foam densities depending on budget), latex, memory foam, and microcoils and are transparent about the type and quality of the materials that they use. Both Orlando Mattress and Atlas Mattress can provide information about the materials inside any of their mattresses but at the Atlas Mattress Factory showroom their first language is Spanish so while they can certainly answer general questions … for more technical questions it may be a good idea to call Orlando Mattress if you don’t speak Spanish. They can also custom build.
Denver Mattress® - The Easiest Way to Get the Right Mattress Daytona Beach, FL. Regional factory direct manufacturer who makes a wide range of traditional innerspring mattresses including some with latex in the comfort layers and their iChoice which is a mostly latex mattress with either a latex or memory foam topper. Some good quality and value.
Find an Original Mattress Factory Store Orlando, Ocoee, Kissimmee, Apopka, Lake Mary, FL. They are a regional factory direct that manufactures all types of mattresses. Their mattresses include a two sided latex hybrid and memory foam models as well as traditional innerspring mattresses. They have some good quality and good value choices.
http://www.relaxincomfort.com/ Winter Park, Sanford, The Villages, Windermere, FL. They carry Savvy Rest mattresses which are a line of high quality component latex mattresses that give you a choice between organic Dunlop and 100% natural Talalay latex but I would also make some careful value comparisons here because they are also in higher budget ranges than other similar mattresses.
