Will VÅGSTRANDA Pocket spring mattress, medium firm/white, 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.

VÅGSTRANDA ships as one box, and it is a heavy one: 65¾″ × 17¾″ × 17¼″ at 109 lb 6 oz. IKEA rolls and compresses the queen mattress, so instead of a floppy slab you get a short, dense block that two people can carry and one person will regret. The length is friendly; the weight is the problem, and the box gives you no handles. Most hatchbacks take it with the rear seats folded, and a wagon or SUV swallows it without drama. Load it last, on its side, so it slides straight out at home, and keep the wrapping sealed until the bedroom: once it expands, it never rolls back up.
