Will MARKUS Office chair, Vissle dark grey, Medium fit in a Mercedes Benz A-Class 2019?

The A-Class gives you a hatchback boot with a modest mouth, 94 cm wide and 73 cm tall. The floor runs 82 cm with the seats up and nearly doubles to 151 cm folded, a 69 cm gain that is this boot's strongest card. It narrows to 99 cm at the back, so wide flat-packs sit better on the diagonal. The load lip is fairly high at 65 cm with an 11 cm 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.

MARKUS ships as a single box of 98 cm × 59 cm × 23 cm: short by flat-pack standards but deep, closer to a stout crate than the usual thin slab. At 22.36 kg it is a one-person carry if you keep it close to your body, though the depth makes it awkward to hug through a doorway. Nearly any car takes a box like this with one rear seat folded, and bigger boots manage it without folding anything, which makes this one of the simpler IKEA collections you will do. Slide it in flat on its 59 cm side rather than upright, and load it last: a 23 cm thick box blocks more of the aperture than you expect.
