Shelf units usually arrive as a frame plus a bag of panels you assemble in the dark. The Stella keeps both tiers permanently linked to the frame, so a 7 cm flat slab opens in one motion into a three-level stand with nothing loose to lose - and folds back just as flat into the carry bag that ships with it. You end up with four working surfaces instead of a tabletop: a top plate at 71 cm with a 1.0-unit IGT space cut into it, two full shelves underneath for crates and cookware, and a side table that folds out at 55 cm. That 55 cm is deliberate - it is set to meet a camp table, so you can butt the Stella against yours and run one surface across both.
