Help pls! Old Uppababy converts to double?

[principessa112]

Hi all
I'd really appreciate some advice. I have a 2 year old and another on the way very soon. We've bought an old Uppababy vista on eBay and it came with a toddler seat and bassinet. We asked if it would convert to a double and the seller said yes...but I can't find how to convert it. I've seen a few things online which say I need to buy a rumble seat to make it convert. I'd be gutted if that's true, as we can't afford to buy any more gear.
Is anyone able to help please?
Thank you so much X

I think you need to get a runble seat. Try ebay again?

I believe that is true. Maybe email Uppababy or ring John Lewis.

Oh dear! Thank you x

Yeah. You'll need a rumble seat to convert. Make sure it's suitable for the older uppababy as the chassis changed in 2015

Oh, and you can't use a rumble seat with the bassinet, just with toddler seat or car seat, so you may need a newborn insert for toddler seat too if you need to use that for the baby

But it is a fab pram btw!

Yes you need a rumble seat and as pp said it doesn't work with the bassinet so you also need the newborn "snug seat" to level out the baby's seat
