UPPAbaby Vista Lower Adapters - used to create more space between seats in a double stroller configuration. They are compatible with UPPAbaby Vista strollers from 2015 onwards. The adapters allow for the attachment of a second seat, bassinet, or car seat in the lower position. Excellent condition, just minor signs of use P.S. these were used with Uppababy Vista adapters which I sell separately; happy to combine postage if you need both
