Wheels

Points 50MM 60MM
Mobility Slightly less smooth movement, especially on carpets. Rolls more easily, requiring less force to move the chair.
Stability Lower to the ground, slightly more stable. Higher off the ground, which may make the chair feel a bit taller but not significantly less stable.
Durability Smaller wheels tend to wear out faster, especially on rough surfaces. Larger wheels generally last longer and handle different surfaces better.
Comfort Less shock absorption on hard floors. Provides better cushioning and smoother movement over bumps or uneven surfaces.
Floor Compatibility Work fine on hard floors but may struggle on carpets. Better for both hard floors and carpets due to larger contact area.
WHICH ONE TO CHOOSE ? For carpeted floors: 60mm wheels are better. For hard floors: Both work, but 60mm offers smoother movement. For durability and better mobility: 60mm is the better choice.
