Will MARKUS Office chair, Vissle dark gray, Medium fit in a Toyota Corolla 2019?

The Corolla gives you a saloon boot: long once you fold, but pinched at the back. The opening is 39″ wide × 30⅜″ tall, and the floor runs 31⅞″ with the seats up, reaching 59⅞″ folded, a gain of 28″. The catch is the narrow point of 26⅜″, where the wheel arches close in, so wide boxes can jam even when the length is fine. The sill sits at 28¾″ with a 7½″ drop. It takes suitcases and medium boxes happily, long flat-packs only with the rear seats down. Load the widest item first, before the space narrows.

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.
