Why Seventeen Twenty-One

A sofa built to
outlast the question.

Most sofas are replaced within seven years. The Comma is designed so that never has to happen. Here is exactly why.

Seventeen Twenty-One

Designed to adapt.
Built to stay.

Move homes. Rework your layout. Add a seat. Swap a cover. The Comma is designed so your sofa changes with your life, not against it.

Fast furniture brands

Built for a single setup. Replaced on a cycle.

Fixed form, fixed fabric. When life changes, the answer is usually a new sofa. That cycle is expensive and almost always unnecessary.

01Modularity that actually means something
Seventeen Twenty-One

Arms detach. Seats reconfigure. Buy a 2 Seater today and add a module next year. Every module is upholstered on all sides, so it works anywhere in the room.

Fully reconfigurable system
Typical modular sofas

Choose your layout at purchase. Arms stay fixed. Reconfiguring is not on the table after delivery day.

02Covers that wash, refresh and replace
Seventeen Twenty-One

Velcro off. Machine wash, every fabric. Back on in minutes. Replacement covers are sold individually, so a worn fabric is never a reason to replace the whole sofa.

370 recycled bottles per Bouclé sofa
Typical sofas

Fixed upholstery. A spill is a cleaning bill. A style change is a reupholstery quote. A worn cover is a new sofa.

03Foam density that proves the comfort claim
Seventeen Twenty-One

The Comma uses 42kg/m³ foam, built in multiple layers. The premium residential benchmark is 32 to 35. The Australian market average is around 19. That difference is what you feel after three years of daily use.

Most Australian sofas

Foam density is rarely listed on a product page. That omission is itself the answer. Sofas that flatten in two years were never built to last.

04A solid larch frame, finished on every side
Seventeen Twenty-One

Solid larch frame. Alligator clips lock the modules together firmly and stay out of sight. Unclip, move, reclip, no tools needed. Backed by a 10 year frame warranty.

Typical modular sofas

Exposed connectors and unfinished backs. The sofa only looks right one way round, pushed against one wall.
