Hi All, Just back from a short stay in Paris, no feet left ! Anyhow my OH and I travelled by Euro star ( fantastic ) and were most impressed with the headrests used. Now there is no way you could fit rests that size into my baby, but it got me into thinking about making something a bit more laterally supportive. So here is the question, is there any technical or legal reason to stop me from altering the existing rests ?
