Hi cburgess625,
Congratulations on your new mattress 
It sounds like you made some great choices and I’m looking forward to hearing your feedback about how both of you like it when you’ve received everything and had the chance to sleep on your new sleeping system for a bit.
The only thing I would suggest is that you check under your steel bedframe to check that the mattress isn’t sagging into the gaps between the wires too much (see post #10 here).
Thanks for letting us know what you ended up deciding!
Phoenix
