Will MULIG Drying rack, indoor/outdoor, white 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 MULIG drying rack ships as one flat box, 47¼″ × 22½″ × 3″, and at 9 lb 9 oz you can carry it under one arm. This is about as easy as IKEA transport gets: a single package, barely any weight, just a wide flat rectangle. Almost any car takes it, back seat included, and most trunks swallow it without folding anything. The one dimension to respect is the 22½″ width, which meets a narrow opening at an angle rather than head on. Slide it in like a tray, corner first, and keep the box flat so the cardboard does not crease across the rails.
