Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Queen fit in a Honda Civic 2022?

The Civic gives you a boot that is wider than it is tall, 37¾″ across the opening and 29½″ high. Seats up you get 36¼″ of floor, which suits suitcases, boxes and a weekly shop without much fuss. Drop the rear bench and the floor stretches to 70⅞″, a gain of 34⅝″, enough for longer flat-pack cartons loaded through the cabin. The narrow point of the floor is 34¼″, so very wide boxes catch before they are fully in. The sill sits 26⅜″ off the ground with a small 6¼″ drop, so lift, do not drag.

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.
