Sorry to sound silly , but are you talking about the Buggy board? The attachment that a toddler can stand on?

If so, my sister used hers with her Maclaren Quest stroller. I have no idea if hers has the double attachment though! Maybe you could take it into the shop with you to try it out?

Depending on your budget, I highly recommend Maclaren strollers! I have two Maclaren Quests, one for the car and one for walks to the park and I love them . I bought mine second hand so I didn't pay a fortune
