Hi Jzschmity,
Iām glad you found us ājust in the nick of timeā 
The first place I would start with your mattress research is post #1 here which has the basic information, steps, and guidelines you will need to make the best possible and most suitable choice and will hopefully help you avoid the chain stores and major brands (or any brands for that matter) that donāt disclose the quality of the materials that are in their mattresses.
Some of the better possibilities in the Saint Cloud area Iām aware of are listed in post #5 here and there is also a link to the better options in the general Minneapolis area which may carry some better value yet.
