Will MARKUS Office chair, Vissle dark grey, Medium fit in a VW T-Roc 2023?

The T-Roc gives you a short but usable boot that transforms when you fold it. With the rear seats up the floor runs 78 cm deep behind an opening 113 cm wide and 86 cm tall, so it takes the weekly shop and a couple of cases, not long loads. Drop the rear bench and the floor stretches to 148 cm, a gain of 70 cm that lets flat-pack furniture in. The floor narrows to 101 cm at the back, and the sill sits 77 cm up with a 22 cm drop to the floor below. Load heavy boxes onto the sill first, then slide them forward over that drop.

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.
