Will MARKUS Office chair, Vissle dark grey, Medium fit in a Volvo XC40 2023?

The XC40 boot is an upright, square space rather than a long one. Seats up, you get 91 cm of floor behind an opening 106 cm wide and 73 cm tall, so wide boxes slide in but long ones stall. Its best trait is the fold: drop the rear bench and the floor stretches to 168 cm, a gain of 77 cm. The floor narrows to 101 cm at its narrowest, so tall flat boxes suit it better than very wide loads. The sill sits at 75 cm with no drop to the floor, so you push loads straight in at sill height instead of lifting over a lip.

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.
