Will MARKUS Office chair, Vissle dark grey, Medium fit in a Skoda Octavia Combi 2025?

This is a proper estate boot, built around length. The opening is 103 cm wide and 78 cm tall, the floor runs 109 cm with the seats up, and folding the bench stretches it to 186 cm, a gain of 77 cm that changes what the car carries. Between the arches you keep 100 cm of width, so long flat-pack boxes lie flat instead of riding at an angle. The limit is the 78 cm opening height: tall boxes go in lying down or not at all. The sill sits 64 cm up with a 10 cm drop to the floor, so slide heavy boxes over the lip rather than lifting them clear of it.

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.
