5. Tuxedo Sofa
Borrowing its name from the town of Tuxedo Park in New York, the tuxedo sofa is considered one of the hints signaling modernism in the 1920s. The style is defined by arms the same height as the back (usually taller than other sofa designs mentioned in this post), inspiring glamor and elegance.
The first versions of the sofa came with a single row of tufts and exposed legs. Pillows are optional but add comfort, especially to a couch with high arms.
