Will POÄNG Armchair, birch veneer/Knisa light beige fit in a Mazda CX-5 2023?

The CX-5's cargo opening measures 41¾″ wide by 31⅛″ tall, with 37¾″ of floor behind it when the seats are up. Fold the bench and the floor stretches to 66⅞″, a gain of 29⅛″, which is what makes longer loads possible at all. The floor holds 41⅜″ at its narrowest, so wide flat boxes lie level instead of wedging. Short, boxy loads fit fine seats up; anything long depends entirely on folding. The liftover sits at 29⅞″ with a 2″ drop to the floor, so lift heavier boxes clear of the sill rather than dragging them across it.

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.
