Hi clogsdon,
As you can see in the quality/durability guidelines here … quilting layers that aren’t more than “about an inch or so” thick won’t have a meaningful effect on the durability or useful life of a mattress. The BestMattressEver uses all high quality high quality and durable materials and as you can also see in my comments in post #2 in the topic we are posting in (and unlike some of the other simplified choice mattresses) there are no lower quality materials or weak links in the mattress that would compromise the durability or useful life of the mattress even relative to higher weight ranges than yours.
