Hi hridenoure,
Here are the better options I know about that are in reasonable driving distance of the Springdale, Arkansas area …
Harness Mattress 3rd generation local manufacturer in Harrison who makes mainly innerspring/polyfoam mattresses. He probably doesn’t make old style innerspring/natural fiber mattresses or latex mattresses but would be worth a call to make sure.
Denver Mattress® - The Easiest Way to Get the Right Mattress Regional manufacturer with outlets in Fayetteville, Little Rock, AR, Tulsa, OK, and Joplin and Springfield, MO. They are a regional factory direct manufacturer that makes a range of mattresses including their iChoice which is a “mostly latex” mattress with either a memory foam or latex topper. They disclose all the information about the materials they use in their mattresses and are typically good quality and value (and certainly better than mainstream brands). I would avoid the major brands they also carry.
http://www.yellowpages.com/rogers-ar/mip/ideal-mattress-mfg-co-14228660 Local manufacturer in Fayetteville and Rogers, AR. Talked with her and they’ve been making mattresses for 68 years. Makes mostly 2 sided polyfoam but can make latex and memory foam as well. Said she has a 40 year old piece of latex that people can try if they want but nothing on the floor because its too expensive. No web presence and the location in Rogers is the head office.
http://joplimo.com/ Rogers, Fayetteville, AR. They carry a range of innerspring, memory foam, and latex mattresses that they designed and are made by the Restonic factory in Springfield. They also carry Sleeptronic mattresses. They will also provide any information their customers need about the materials in their mattresses and can also do custom builds.
http://www.mountainairorganicbeds.com/ Springdale, AR. Carries a line of component latex mattresses that use 100% natural latex in several thicknesses and with various layering options available.
http://www.brashears.com/Our_Locations/ Springdale, Berryville, Branson, AR. They are a retailer that carries Jamison mattresses which are high quality mattresses and include latex and latex hybrid models that may be worth testing.
A little further away … the better options or possibilities I’m aware of in the Tulsa, OK area are listed in post #2 here.
Post #4 here also includes the better options I’m aware of in the Fort Smith area.
Post #4 here includes the list for the Neosho/Springfield, MO area.
If none of these are suitable … then an online purchase from one of the manufacturers mentioned earlier would likely be your best source of good quality and value.
