What to measure

When measuring for a chair mat, it is important to consider: 

  •  the size of your chair base

  • Side to side movements along your desk

  • Back and forth movements when standing and sitting

  • The area under your desk where you rest your feet 

Chair roll area

Your roll area includes:

  • Sideways movements made when retrieving items from drawers and collaborating with colleagues,

  • Backwards and forward movements made standing, sitting and tucking the office chair under your desk.

  • The space under the desk where you rest your feet - a chair mat can also protect floors from dirt and damage caused by footwear.
