Great to hear you are still enjoying our products, the good news is that the Astral, Mercury and Galaxy car seats are all compatible with your frame. For the Astral you will need the V2 adapters (you might still have them from your first purchase), and for the Mercury and Galaxy you will need Stomp universal adapters.
Car seats can be found here:
Stomp Universal adapters can be found here:
If you don't have the V2 adapters and would like them you will need to open a new ticket on the contact us form as we no longer list them on the website.
