I doubt you'll get much from toys R us - try mentioning Trading Stadards to them! They should recall faulty/dangerous goods (which this obviously is), whether the warrenty has run out or not. My friend's buggy collapsed whilst her two year old daughter was in it. The incident was followed by 5 hours in the A&E cos her two year old had been partially scalped. If Toys R Us don't sort it, tell trading standards and they will.
