UPPAbaby VISTA Lower Adapter

The lower adaptors fit the mesa car seat and bassinet ONLY. Will work just fine if you plan on putting the car seat or bassinet at the bottom, however I purchased thinking it would fit my toddler seat. I purchased upper adapters for the car seat which does work with the car seat, bassinet or toddler seat. Turns out that if you want to make a double stroller and don’t want toddler on the top and car seat on the bottom, you will need 1) a RUMBLE seat (different from toddler seat which came with the stroller) and 2) lower Rumble seat adapters. You will then be able to have baby on top and toddler on the bottom.

I got the adaptors to give myself the option to put another bassinet on the stroller. Works great.

Works for being able to attach bassinet to bottom position. You will also need upper adapters to enable the bassinet and seat to be used at the same time. They really should be sold as a set of both upper and lower as both are needed for them to be used. A little tricky to attach but not too bad.

bought this for our stroller so it can hold the car seat and the regular stroller seat as well and it has worked has described

Doesn't fit with the toddler seat even though it says it does on the instruction manual? Very silly. Shipped very quickly though
