Diffrient Smart

We believe it’s important to understand features that make each chair unique so you can find what works best for your needs and preferences. Get to know the ergonomic benefits of each feature and how it relates to your work style.
Diffrient Smart
  • Back Support
    • This chair instantly gives you the right amount of back support with its pivoting backrest that automatically adjusts as your spine moves. Its reclining capabilities reduce stress on your back and encourage movement throughout your workday.
  • Lumbar Support
    • Form-sensing mesh provides additional lower back support. This feature mimics the natural curve of your spine to provide the greatest amount of lower back support when seated, which is important if the chair is used frequently or as a primary task chair.
  • Armrest Support
    • Armrests offer extra support throughout the workday to reduce strain on your upper arms and neck. Height-adjustable armrests complement the chair’s design and provide the right amount of support.
  • Seat Cushion
    • This chair’s contoured foam cushion helps minimize pressure on your thighs and knees to ensure lasting comfort and proper circulation in your legs.
  • Adjustable Seat Depth
    • Adjusting your seat depth to thigh length provides a comfortable, healthy sit. This is a helpful feature if the chair will be used by more than one person.
  • Back Tension
    • Self-adjusting tension control automatically regulates the effort required to recline. This is an especially helpful feature if the chair will be used by multiple people, as it automatically adjusts to accommodate personal preferences.
  • Adjustable Seat Height
    • This is a great feature if the chair will be used by multiple people or at more than one work surface. Position your seat height so thighs are parallel to the floor and feet are flat for healthy circulation in your legs.
  • Casters
    • This chair features hard plastic casters that are ideal for carpeted floors. Soft plastic casters, best for hard floors, can be ordered. Contact us for details.
