Will SLATTUM Upholstered bed frame, Vissle dark gray, Queen fit in a BMW X1 2024?

The X1 gives you a compact SUV boot with a fairly wide mouth, 42⅛″ across and 28⅜″ tall, but a short floor of 35⅜″ with the rear seats up. Fold them and it nearly doubles to 64⅝″, a gain of 29⅛″, which is where this boot earns its keep. It takes medium boxes and multi-package loads well, though the longest flat-packs, tall wardrobe frames and full bed rails, will not clear whether the seats are up or down. The floor narrows to 39¾″ at the back, so load the widest item first. The lip sits 28″ up with only a 1⅛″ drop to the floor, so expect a high lift then a flat slide.

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.
