What a great idea and product, takes the hassle out of the elder child wanting to be carried when they become tired miles from home.......this was all found out once i'd worked out how to fit it!! A word of warning.....if like us you have a Mclaren Techno XT, the way the picture on the box shows fitting to the frame makes it totally impractical. It can't be fitted just above the folding mechanism because the chair then won't fold and it can't be fitted just below it because then the board cannot be folded up while temporarily not being used.
I found the best way to fit it is literally just above the rear wheels with the connecting points facing towards the front wheels. Then folding both the chair away and folding the board up when not in use can both be done with ease!! Don't follow the box as is totally misleading and even uses the mclaren chair as the example!
