Will MULIG Drying rack, indoor/outdoor, white fit in an Audi A4 Avant 2022?

The A4 Avant pairs a wide mouth with real height: the opening measures 40⅛″ across and 33½″ tall, so upright boxes pass through without a tilt. The floor gives you 41⅜″ with the rear seats up and 72″ once they fold, a gain of 30¾″, with 39″ between the wheel arches at the tightest point. The lift-over sits at 24¾″ and the floor is only 2″ below it, almost level, so long boxes slide in instead of dropping in. Tall furniture cartons and long flat packs both do well here; extra-wide boxes meet the 39″ pinch first. Slide heavy loads across the sill on a blanket rather than lifting them over.

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.
