Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Queen fit in a Tesla Model Y 2023?

The Model Y boot is long and flat, with a deep floor even before you fold. The opening is 39¾″ wide × 27⅛″ tall, and the floor already runs 43¾″ with the seats up, stretching to 76⅜″ folded, a gain of 32⅝″. The sill height is 27½″ with a 0″ drop, so the floor sits level with the lip and items slide straight in. The opening is on the low side, so tall boxes can catch on the way through. It is excellent for long flat-packs and big shops, less so for very tall items. Lead with the long edge and slide it in flat.

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.
