Will MARKUS Office chair, Vissle dark grey, Medium fit in an Alfa Romeo Giulietta Turismo 2010?

The Giulietta Turismo boot is wider inside than it is at the door: 102 cm across the floor, but an opening of 81 cm wide by 76 cm tall. That mismatch is the thing to plan around, because anything that suits the floor still has to pass the mouth. Behind the seats you have 77 cm of length, which is a shopping boot. Fold the bench and you get 147 cm, a gain of 70 cm. Medium boxes and soft loads suit it best. Feed a long flat pack through the narrow mouth at an angle, corner first.

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.
