I flew from Chicago to Mumbai with a layover in Doha through Qatar airways and stayed in business class. I don't know that I can ever go back to coach when flying internationally again. The staff was extremely attentive, friendly, and helpful. The food was very good (for airline food), and the business class pods were extremely comfortable. The movie selection and screen was very good, and it made flying a pleasure.
The seats go pure horizontal in business class so that you can sleep easily and they gave you comfortable blankets and two pillows to use. The seats are padded reasonably well, so while not quite as comfy as a bed, they are still very comfortable overall.
