While I was originally sceptical about the cost - but this was 110% worth the investment. Just used with my 2.5 year old toddler to get from Australia to Europe, and it was great. She could lay down to nap, play with her toys without losing them all under the seat in the first 10 seconds, and just generally stretch out.
Bonus, mum even got to share it and put her feet up too, might not work for all but my short legs came in handy!.
Looking forwar to using this for the next several years of adventures, and can't wait to see how it does next on some long train trips!
