Will MARKUS Office chair, Vissle dark grey, Medium fit in an Aiways U6 2023?

The U6 gives you a long, level boot. The opening is 100 cm wide by 68 cm tall, the floor runs 100 cm with the rear seats up and 181 cm folded, and the width between the arches is 102 cm. The trait worth knowing is the sill: it sits 75 cm up with only a 1 cm drop to the floor, so the load bed stays flat from the bumper inwards. That suits heavy boxes you would rather slide than lift, and long flat loads once the bench is down. Fold the seats before you start loading, not halfway through.

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.
