Will MARKUS Office chair, Vissle dark grey, Medium fit in an Opel Astra 2022?

The Astra gives you a compact hatchback boot built around a 95 cm wide by 71 cm tall opening. With the rear seats up the floor is only 73 cm deep, so it handles shopping, cases and shorter flat boxes rather than long loads. Fold the bench and the floor grows to 154 cm, a gain of 81 cm, which is where this boot does its best work on an IKEA run. The floor narrows to 102 cm across the back, and the lip sits 69 cm off the ground with a 13 cm drop to the floor. Anything long goes in on the diagonal through that 95 cm opening, so measure the opening first, not just the boot.

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.
