Im Gegensatz zur Konkurrenz wie Embraer oder Bombardier, welche mit einer 2+2 Bestuhlung unterwegs sind, verfügt der Superjet über eine 3+2 Bestuhlung. Dies wurde durch einen breiteren und höheren Rumpf erreicht. Dadurch verfügt der SSJ100 auch über einen breiteren Gang (508mm|20"), sowie bequeme Sitze (462mm|18.2"), eine grosszügige Ganghöhe (2121mm | 83,53") und grosse Ablagefächer.
Weiter wurde ein LED-Lichtsystem eingebaut, welches die Farbe ändern kann und dimmbar ist. Insgesamt hat der Superjet so ca. 20% mehr Platz wie seine Mitkonkurrenten.
Bis heute wurde der Superjet in Versionen von 87 bis 103 Sitzen ausgeliefert. Hauptausstatter ist die amerikansiche Firma B/E Aerospace Inc. Dabei setzt man auf das Modell "Spectrum" und für die Buisness Class das Modell "Spectrum 1". Die Endmontage findet bei Aviastar-SP in Uljanowsk statt.
Interjet bevorzugte ein neues Design und so wurde mit Pininfarina ein komplett neues Interieur entwickelt. Das Design erhielt 2013 den "red dot design award"! Die Ausstattung wird in Tessera hergestellt und beim Sitz von SJI in Venedig endmontiert!
