I also have a secondhand Duet! The seat fabric on mine is super worn and no longer holds even my youngest's weight without gradually (and this is happening faster and faster!) unzipping and unpopping until my kid is hanging rather lower than she should if I'm not quite on top of constantly adjusting it... I thought about trying to patch it up but it's really frayed and my sewing skills are not that good so I'm not confident I could do it. I can't find any replacement seat fabric for any of the older versions and I'm really struggling to find any info re. compatibility - why do they not add this info to the blurb on all their spare parts?!
So, my question is, will the Mountain Buggy Duet V3 seat fabric fit (I think) a V2 frame?
Thanks in advance!
