Do I need the deluxe or super-deluxe version, or is the original fine?

The reddit threads we read are split: some users say the super-deluxe's added back support and firmer front are worth it for long feeding sessions and larger babies, while others report the standard deluxe is plenty firm and the upgrade isn't necessary. If you have a longer torso or anticipate cluster feeding, the firmer/taller versions get more recommendations.
