Sci-fi has such great tales and ideas to tell 
It's a nice idea, from a certain perspective.
However, I can see if such a technology were possible it would be the preserve of the rich. Creating tiers of society based on time 'awake' and time 'asleep' being decided on by wealth, power, or usefulness.
The upshot would be successive dynasties far outliving the ordinary man, who might be able to afford a couple of years sleeptime here and there, ensuring their position and wealth for ages untold.
Imagine only waking once every 50 years or so to manage your affairs, then leaving the running to trusted servitors, whilst your less well off family age around you. Or perhaps sleeping even longer, outliving your great-grandchildren or business rivals.
Naturally such a society would have to have a top down government secure in its position of wealth and power to enforce this new caste system.
Now imagine those who feel that this long sleep life extender renders out of us what makes our humanity so precious - our social bonds, our loves and desires, passions... all undone by the cold of artificial sleep to prolong life. What conflict would be waged by those tired and jaundiced by such a universal detachment from themselves?
