Hi Mrsbitterchef,
Welcome to the Mattress Forum! 
I switched your post to a new topic of its own since your question was outside the scope of the more general topic you originally posted in.
I don’t know the specifics of the materials inside the mattress you are asking about and they aren’t listed on their website but if you can find out the information listed here and post it on the forum I’d be happy to make some comments about the quality of the materials and the mattress “as a whole” and let you know if I can see any obvious weak links in the mattress that would be a cause for concern. Without this information and knowing the type and quality of the materials inside a mattress it’s not possible to make any meaningful comments about the mattress.
You may have seen this already but just in case you haven’t … the better options or possibilities I’m aware of in and around the Phoenix area (subject to making sure that any mattress you are considering meets the quality/value guidelines here) are listed in post #4 here.
