When design geta in the way of safety

When i was flying from hong kong to london i met A brave mother was travelling alone with her two kids - one 3 yrs old, the other 7 months. I noticed the way she set up her inflight cot. One of the safety straps was left undone because it retricted the baby's movement, as well as the interaction between her and her child. Needless to say the safety of the baby was comprised but in the eyes of the mother, it was worth it. This is a fine example of a poorly designed piece of furniture. May be the cot and the table should have some kind of interlock, may be the table should fold out as a cot. Whatever the solution is, there is a better way.
