Will POÄNG Armchair, birch veneer/Knisa light beige 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 POÄNG armchair ships as one flat box, 29 inches by 26 1/4 inches and only 2 3/4 inches thick, so it behaves like a large stiff panel rather than a bulky load. At 18 lb 1 oz it is light enough to carry one-handed, and the thin profile slides behind a front seat or flat across most boots. The awkward part is the width, not the weight: the panel will not flex, so do not wedge it into a curve. Lay it flat, protect the corners, and almost any hatchback or estate takes it without folding a seat.
