About the Volvo XC40 2023 boot

The XC40 boot is an upright, square space rather than a long one. Seats up, you get 35⅞″ of floor behind a 41¾″ wide by 28¾″ tall opening, so wide boxes slide in but long ones stall. Its best trait is the fold: drop the rear bench and the floor stretches to 66⅛″, a gain of 30⅜″. The floor narrows to 39¾″ at its narrowest, so tall flat boxes suit it better than very wide loads. The sill sits at 29½″ with no drop to the floor, so you push loads straight in at sill height instead of lifting over a lip.

About the BILLY Bookcase, oak effect, 31 1/2x11x79 1/2 " package

The BILLY bookcase ships as one long, flat, heavy box: 81¼″ × 11¾″ × 5″ and 87 lb 5 oz. The length is the challenge, not the bulk. That long panel needs floor space most boots only find with the rear seats down. The flat-pack board is rigid, so it will not bend around a wheel arch or curl into a short boot. An estate, a hatchback with the seats folded, or an SUV handles it best. Slide it in long-edge first, low and flat, and protect the corners, because at this weight a dropped end can split the board.
