Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Full fit in an Alfa Romeo 159 2010?

The 159 gives you plenty of height at the opening and less width than you would like. The mouth measures 36⅝″ wide by 50¾″ tall, so tall boxes go in easily, and the floor matches it at 36⅝″ across its narrowest point. Length runs 40⅛″ with the seats up and 69⅝″ folded, a gain of 29½″. Wide, rigid cartons are the ones that fight you here. The sill is 30⅜″ off the ground with a 9⅞″ drop to the floor, so lift over the lip and lower, rather than sliding.

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.
