Will MARKUS Office chair, Vissle dark gray, Medium fit in a Peugeot 5008 2021?

This trunk lives two lives. With all rows up the 5008 gives you a 13⅜″ shelf, groceries and not much more. Fold the seats and the floor runs 74″ deep, a +60⅝″ swing, behind an opening 44½″ wide × 31½″ tall. The floor stays 45¼″ across at its narrowest, wider than the mouth itself, so any box that clears the opening will sit flat inside. The liftover is 27⅛″ with a ⅜″ drop to the floor, close to flush, so you slide heavy boxes in instead of lowering them. Long flat packs are the easy case; tall cartons still have to duck under that 31½″ opening, so check height first on borderline boxes.

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.
