Hi Thrasher,
I would echo jankdc’s comments 
The information you need to assess a mattress and identify any potential weak links or make meaningful comparisons with other similar mattresses is in post #4 here. If you can find out the specifics from them and post them here I’d be happy to help you identify any possible weak links or make some comments that may be helpful.
If you’ve spent a couple of hours with the tutorial post and the information it links to you will likely know more meaningful information about mattresses and materials than about 90% of the salespeople in the mainstream industry … as sad as that may be.
