A- The original Max sofa has a thick feather insert. This means that it needs more maintenance than regular feather cushions. The sofa looks best when it is nicely patted and Velcro in covers are pulled tight.
If there is a severe maintenance issues with feather inserts, then you could try replacing all seat cushion inserts to V2 which is foam. This will change the comfort though by being a bit firmer. One of the reason for the changes were incorporated for this maintenance issue.
