The Scottsdale location was a little difficult to find, but I called in and they explained it well. It's right next to Posh restaurant, facing Scottsdale street. The parking garage is on Highland Rd, called Camel Village.
Leo greeted me at the door and was extremely friendly and welcoming. I couldn't decided between the AS2 and AS3, so he showed me the difference between the two and let me try them out. The AS3 was firmer than I expected for a mattresses classified under "soft" category, but I've always preferred firmer mattresses, so I still went with the AS2.
Leo was super helpful and helped me place the order immediately afterwards and explained the shipping/packaging too.
I highly recommend coming to this location and trying out the mattresses for yourself if you're not sure which one to buy.
