Unique Double stroller

I saw a double stroller being advertised a few weeks ago but i wasnt paying enough attention and didn't get the name. Its a double stroller but the front seat can be folded and slides underthe maijs seat. So i guess u can say it turns into a double strolleror it reverts into a double or single stroller. Ive been searching google trying a bunch or different word combinationsbut unfortunately no luck. If u think u know the stroller brand im talking.about plz leave the name
