Will SLATTUM Upholstered bed frame, Vissle dark gray, Queen 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.

SLATTUM in Queen packs the whole upholstered frame into one long flat box: 65½″ × 29″ × 4″, weighing 81 lb 13 oz. The shape is the difficulty: over 65″ long, wide enough to argue with most trunk openings, and heavy enough that the thin box flexes when carried by the ends. It suits an SUV, a wagon, or any car with the rear seats folded flat. Feed it in low corner first on the diagonal and support the middle as you slide: the packaging gives up at the handholds long before the frame inside is at risk.
