Will VITTSJÖ Shelf unit, black-brown/glass, 39 3/8x68 7/8 " fit in a Mercedes Benz A-Class 2019?

The A-Class gives you a hatchback boot with a modest mouth, 37″ wide and 28¾″ tall. The floor runs 32¼″ with the seats up and nearly doubles to 59½″ folded, a 27⅛″ gain that is this boot's strongest card. It narrows to 39″ at the back, so wide flat-packs sit better on the diagonal. The load lip is fairly high at 25⅝″ with a 4⅜″ drop to the floor, so lift heavy boxes in rather than drag them. Short and medium cartons go in seats up; long bed and wardrobe frames need the fold, and the very longest need a roof rack. Fold the seats before you load.

VITTSJÖ ships as one long, flat carton, 79¼″ × 15¼″ × 3½″ and 60 lb 12 oz. The length is the awkward part: a rigid flat-pack just under 80 inches that will not bend around a tight boot mouth, and there is glass inside, so the box does not forgive a hard knock. A car that takes it easily is an estate, an SUV, or a hatchback with the rear seats folded flat. In anything smaller, load it diagonally from a folded seat back toward the boot, longest edge leading, and rest it on a blanket. Keep it printed side up so the glass shelves stay flat, and slide it in rather than drop it.
