Six tips for your children’s backpack

  • “The weight of the contents should not be disproportionate to that of the child.” The ISPEL, Institute for prevention and safety at work, gives this indication: the weight of the backpack should not exceed 10% of the weight of the wearer.
  • The backpacks should contain only the essentials for the school day and must be filled bottom to top, with the heavier objects resting on the bottom of the backpack.
  • The backrest should always be rigid and padded.
  • It is better to wear backpacks with wide shoulder straps which will distribute the weight evenly on the kids shoulder.
  • “The backpack should always be worn with both shoulder straps, never carry it on one shoulder. When worn correctly, it helps to keep the back straight and the shoulders even.”
  • “Trolley backpacks can be chosen for convenience, however it is still a burden to the child if it must be dragged for several meters, every day.”
