Hi Tessa,
Congratulations on your new mattress 
I think you did some great research and ended up making a great choice for a mattress that “fits” your criteria and I’m really looking forward to your feedback when you receive it and have had the chance to sleep on it for a bit.
I also found that they were very knowledgeable and helpful when I talked with them on the phone (see my comments in post #3 here).
