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 KALLAX Shelf unit, white, 43 7/8x57 5/8 " package

The KALLAX shelf unit arrives as two packages, and the larger one measures 56½″ long, 16″ wide and 5″ thick. That length is what decides the car. The whole order weighs 95 lb 3 oz, so it is a two-person lift even though the boxes look thin. Flat-pack board has no give, so you cannot bend it around a wheel arch or a seat back. An estate or an SUV with the rear bench down handles it comfortably. Load the long box first, on its edge and angled towards the far corner, then slide the second one alongside.
