Hi hoyt,
They are a manufacturing member here which means that I believe they compete well with the best in the industry in terms of quality, value, and service yes. They are well worth talking to.
They are very knowledgeable about all the materials and types of latex they use and will give you reliable information and guidance but there is also more information about the different types of latex in post #6 here.
You can see the Worlds Best Bed on their website here and the more detailed specs are listed in post #2 here.
