Will POÄNG Armchair, birch veneer/Knisa light beige fit in a Seat Ibiza 2022?

The Ibiza's cargo area is compact and honest about it: the opening is 34⅝″ wide by 32¼″ tall, the floor gives you 26¾″ with the rear bench up, and folding it opens 55½″, a gain of 28¾″. Between the wheel arches you keep 39″, more than the opening is wide, so a box that clears the mouth can settle flat inside. It handles short stacked boxes well and long flat packs poorly; most rejections happen at the opening, not on the floor. The liftover sits 27⅛″ high with a 7½″ drop inside, so rest a heavy box on the sill edge and lower it in instead of pushing.

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.
