Could one be buried in a position other than flat on one's back?

My life is all about comfort, and I’d like my death to be, too. I plan to be buried in jeans and tennis shoes, thankyouverymuch. I would never lay flat on my back with my arms crossed over my chest in life, and I see no reason to do so in the grave, either. Could I be buried on my side, in my typical sleeping position, if I wanted to? Maybe with all my pillows, too. What do you think?
