Hi hes56,
Jeff at Mattress-To-Go is one of the most knowledgeable people I know in the industry and would be one of the better options available in the Detroit area. You can read more about him in post #4 here and he is also one of the “expert” members of this forum and you can read some of his posts here (you can just click this). I frequently link to some of his beducation videos. He also ships the Pure Latex Bliss mattresses across the country.
Pure Latex Bliss makes a line of Talalay latex Mattresses which are very good quality and a frequent topic of discussion on the forum. A forum search on Pure Latex Bliss will bring up many posts and feedback about them. Of course it also helps that Jeff runs on lower margins than most other retailers in the industry.
