Will MARKUS Office chair, Vissle dark gray, Medium fit in a Peugeot 3008 2025?

The 3008 gives you a wide, square cargo area. The liftgate opening measures 40⅛″ wide × 30¾″ tall and the floor stays 39¾″ across at its narrowest, so you keep almost full width right to the back. With the rear seats up you get 39″ of floor, which suits boxed appliances and shorter flat packs. Fold the bench and you gain 26¾″, taking the floor to 65¾″, the biggest single change you can make here. The load lip sits 31½″ off the ground with a 4⅜″ drop to the floor, so lift high, then slide down and forward.

The MARKUS chair travels as a single box of 38½″ × 24¼″ × 9½″, short enough to lie flat in most trunks without folding a seat. The catch is density: 49 lb 6 oz packed into that footprint, so the box is far heavier than its size suggests. There is no long dimension to fight, which makes this an easy load for a sedan or hatchback, and an SUV will not notice it. Treat it as a two-person lift anyway, slide it over the sill on its long edge instead of carrying it flat, and load it last so the weight sits near the opening when you unload.
