Will STRANDMON Wing chair, Nordvalla dark gray fit in a Seat Ibiza 2022?

The Ibiza suits small boxes best with the rear seats up, as the floor is 26¾″ long. Folding the seats adds 28¾″, for 55½″. Some boxes longer than 26¾″ still fit with the seats up, across the boot or at an angle. The tailgate opening is the tight spot: 34⅝″ wide, narrower than the floor (39″ at its narrowest), with 24¾″ of clear height over the loading sill. Inside, the boot is taller, at 32¼″ from its floor, because the floor sits 7½″ below the sill. So lift each box over the sill and lower it to the floor, rather than letting it drop onto its corners.

At 42½″ × 30½″ × 20″, the STRANDMON wing chair box is a bulky block rather than a flat pack, and it weighs 66 lb 8 oz. That bulk works against you: you cannot get your arms around it or hold it close while you walk. Lying flat, it needs 20″ of height and a patch of boot floor 42½″ by 30½″, with the long side either along the boot or across it. Make it a two-person job: take one side each, hands under the bottom edges, and lift and lower it together, so it never drops onto a corner.
