Anyone staying in Magnolia a Tribute Portfolio Hotel?

I stayed there last week, had the best sleep ever, but totally spaced on checking the mattress brand.

If you're there or heading there soon, could you do me a favor and sneak a peek at the brand for me? My back is begging for that mattress.

I tried looking on the Marriott website, but they've got a couple of options and I'm totally lost on which one it was.

Thanks a ton!
