Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Full fit in a BMW X3 2022?

The X3 gives you a wide, level cargo bay. The hatch opens 44⅛ inches across and 31⅛ inches tall, and the floor holds 43¼ inches at its narrowest, so wide boxes that snag in smaller SUVs slide through here. Length is the catch: 37⅜ inches behind the seats, 70⅛ inches once they fold, a gain of +32⅝ inches. The floor sits level with the 27½ inch liftover, no drop on the far side, so a heavy carton pushes straight in. Save long flat-packs for seats-down trips; upright, the bay favors short, wide, stackable boxes. Slide heavy loads in across the sill and spare your back.

The Full size VÅGSTRANDA ships as one roll-packed package, 58¾″ × 18¼″ × 17¼″, so the challenge is bulk rather than length: a dense bundle weighing 90 lb 3 oz. Under 59″ long, it fits across most folded rear seats and into most SUV cargo areas, but it does not squeeze: the 17¼″ thickness is firm and gives almost nothing. Two people make loading far easier than one, and a blanket underneath protects the wrap from tears. Once home, give it space when you cut it open: a roll-packed mattress expands quickly and with force.
