Hi ... Really disappointed that both original and replacement Uppababy Vista in mica grey have become horribly watermarked by rain (look like sweat marks) despite always using rain covers. We always store carrycot or seat indoors and only leave chassis in garage. Has anyone else had this problem ???. Uppababy suggested (via John Lewis) that we wash fabric after use but with four month old baby I don't have time and we would never have bought vista if we knew this was necessary. Strangely, uppababy claimed they had never heard of the problem yet they gave same washing advice to mum with same problem via their Facebook page!?! So dreadfully disappointed as waited ages for baby and now feel so embarrassed when pushing lovely daughter in stained pushchair. John Lewis kept suggesting that we swap to another brand and seemed keen that we buy a bugaboo but we chose uppababy vista after much research and so really don't want to have to go back to the drawing board and choose whole new pushchair as have matching cosy toes etc and other than rain marks we are really happy with vista. We have been speaking to john Lewis about the problem since before Christmas but still no satisfactory resolution not least because uppababy not acknowledging problem. Would love to hear if others have same problem.
