Hi HockeyGoalie29,
I think that the specs you posted were probably from a previous version which were different from the current PLB versions (and they will likely change once again very soon).
As you mentioned though … there are no lower quality materials or weak links in any of their versions so if the mattress was a good match for you in terms of PPP and it also compared well to the other mattresses you were considering based on all the other parts of your personal value equation that are important to you then you certainly made a good quality/value choice :).
