Another Passing Grade for i-stay

This past week, i-stay received another great review. We loaned out three of our laptop bags to an ergonomics tester, Axis Ergonomics. They subjected our strap to its most thorough test yet.

Their conclusions were:

  • The i-stay strap fulfils many of the good design features of a single shoulder strap
    identified in the ergonomics literature.
  • Testing of the strap in use shows that it does not slip off the shoulder when attached
    to a loaded bag as easily as a conventional shoulder strap. This is because of the
    combination of strap width, frictional properties of the material on the underside of the strap, and the shape, size and profile of the load-bearing aspect of the strap.
  • The design features of the strap mean the surface area in contact with the top of the
    shoulder is considerably larger than a conventional strap. This will reduce shoulder
    pressure and, most likely, spinal compression.
  • Since the strap is less likely to slip off the shoulder then the risk of a bag falling
    unexpectedly and being ‘snatched’ before it falls to the ground is reduced. In turn this reduces the risk of a manual handling injury sustained by catching a falling bag.
  • The use of the strap leaves both arms more free to be able to be used with a lesser
    risk of the bag falling from the shoulder.

Or in short:

Another professional commendation. Thank you Andy Nicholson and Axis!
