Will MARKUS Office chair, Vissle dark grey, Medium fit in an Audi Q3 2019?

The Audi Q3 gives you a wide, square boot mouth: 112 cm across and 78 cm tall, so most flat-pack cartons clear the opening with the seats up. Behind them the floor runs 90 cm, and folding the rear bench stretches that to 166 cm, a gain of 76 cm that turns a school-run boot into a proper load bay. The floor stays 100 cm wide at its narrowest, so wide boxes sit flat. The catch is the lip: at 75 cm the sill is a high lift, with a 9 cm drop to the floor. Slide heavy boxes in on their edge rather than lowering them straight 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.
