We got into Calgary late and after reviewing trip advisor booked at the Days Inn. Wasn't horrible (kind of grungy) but beds and pillows were terrible. Worst. Sleep. Ever. My cousin is having a back procedure done so we decided to find a different hotel for the next night. After more thorough research on trip advisor reviews, paying special attention to comments on bed comfort we booked at the Best Western Premier Freeport Inn & Suites. For $3 more per night we were blown away by the difference. It's kind of out of the city (close to airport) but worth it. Beautiful hotel. Great beds. Awesome pillows.
I will give Days Inn this: after explaining to the front desk about the back/bed situation the clerk even phoned a different hotel where she heard they had sleep number beds for us. She was super nice and helpful.
