Inertia +Plus by Allseating gives the Inertia task-chair family a larger seat and back specification. Available with a mesh or upholstered back, this configuration combines a 22-inch-wide seat with a 24-inch-high back for school offices and staff workstations where a more generous chair size is preferred.

The +Plus is a separate dimensional choice, rather than simply an arm or fabric upgrade to the standard Inertia chair. Its Synchro Tilt control is standard, and the visual model selector distinguishes the mesh and upholstered versions before the relevant finish choices appear. Compare the seat and back dimensions with the intended user and available desk clearance.

Seat dimensions: 22 inches wide × 20.5 inches deep.
