Hi jonesenberg,
As you probably know from your reading here you certainly made a great quality/value choice … and congratulations on your new mattress 
Based on the “averages” your choice was probably more suitable than the firmer Aria and I’m looking forward to your comments and feedback once you’ve received it and have had the chance to sleep on it for a bit.
It would also be a more durable choice than most of the hotel mattresses you have probably slept on as well (see post #3 here about hotel mattresses).
