This isn’t anything electronic, but I’m sure that anyone who’s been using a laptop in any room of his/her house, for instance, would find it convenient to place the mandatory cup of coffee or, why not, a mouse. (Personally, my touchpad is sometimes a nuisance, and moving a mouse on the arm of a sofa isn’t very convenient.) This is clearly not the primary use of that sofa hanger created by German manufacturer VANPEY, allright; I’m just being my over-creative self again, which is my opinion part of the fun in toying with new things.
Nevertheless, whether this item is a good idea, an incentive to snack too much, or an accident waiting to happen (ten-thumbed people like me know that a tea cup can be a dangerous involuntary weapon), it will be what we make of it, and it may be pretty convenient to have that mug of coffee under the hand all the same, or, why not, leave a book on it. It doesn’t necessarily have to do with food at any cost, does it?
