Will SLATTUM Upholstered bed frame, Vissle dark gray, Queen fit in a Volvo XC60 2022?

The XC60 gives you a wide, flat, square boot rather than a deep cave. The opening is 44⅛″ wide and 29⅛″ tall, and the floor runs 37¾″ with the rear seats up. Fold them and it nearly doubles to 70⅛″, a gain of 32¼″, so the seats-up length is the real limit on anything long. The floor stays a wide 43¾″ across at its narrowest, which suits flat boxes and multi-package loads. The lip is 28⅜″ off the ground but level with the floor inside, so you slide loads in rather than lift them over a step. For long flat-packs, fold the bench first and load down the middle.

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.
