Let me actually answer this a little better; it’s important to note that the seats don’t fold forward and stay there like in a normal SUV (or the Air). They fold forward and then slide *down* into the subfloor of the Gravity. That is what allows you to fold both sets of seats down and get a literally completely flat cabin, with no bumps.
But: those seats have to go somewhere, and they’re not tiny. So, when the seats are *up*, the space in the trunk where they normally stow is storage space for bags, etc. If they’re down, you can place the bags on top of them. If they’re up, place them where the seats were when they were down. The number of configurations and places to find additional cargo space feels like magic. The whole car feels like they designed a massive shell on the inside, and then just built the car around that. Of course that’s not true, but the amount of space really does make it feel cavernous.
For comparison, when we were in the EQS SUV, one of the other owners was trying to get out of the third row, where his knees were already splayed and out. It turns out in order to let him out, you need to move the second row forward — standard enough. Only it turns out that to move the second row forward, the passenger riding shotgun needs to get out and move the passenger seat forward, so you can move the second row and let the third row out. There was no way to do it otherwise. Nearly the whole car must exit, except the driver.
I almost lost my mind.
