Mattresses at Animal Kingdom Lodge

We returned a week ago from a stay at Animal Kingdom Lodge - Jambo House. I got the best sleep ever in my recent life (having Grandma at home managing overnight blood sugars for me on 2 of the 3 kids we have with diabetes surely helped).

Anybody know what mattress they currently use in their beds and how I could get a similar one?

I found this online, do you think this is up to date?

Is there a way to find a similar one from Simmons without the hefty Disney price tag? We need a king.

I personally have never stayed here but I think your best bet in finding out what mattress they use is to call the resort and ask them. Many hotels and resorts have there mattresses specially made for them but you never know they might be able to suggest something similar.
