Will MARKUS Office chair, Vissle dark grey, Medium fit in an Alfa Romeo Brera 2008?

The Brera gives you a letterbox: the opening is 99 cm wide but only 61 cm tall. Behind the seats you get 95 cm of floor, and folding the rear seats takes that to 152 cm, a gain of 57 cm. The floor narrows to 84 cm at its tightest, so a wide flat box has to go in at an angle. This boot handles long low loads better than tall ones. Plan for the sill: it sits 90 cm off the ground with a 28 cm drop to the floor, so lift high, rest the box on the sill, then let it down.

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.
