MFI polyurethane vacuum molded, ergonomically designed to give great comfort to all.
Problem is that as MFI have not been involved in warship design before, it burns like buggery and gives off a toxic gas. Solved all crew members will have their own Breathing Apparatus. Officers will all get a personal Steward i.e. ABLOGSBAC to carry it for them.
Tons of room on those ships. All of the watchkeepers seating looks fairly comfy and the mess/WR seats look a little...erm... officey but should be okay, I imagine. Probably better [on the eyes/mind] than the old floral pattern stuff which adorns the 42 that I once went on.
As for if it'll be wrecked within 3 months...that's up to Jack.
