About the BMW X1 2024 boot

The X1 gives you a compact SUV boot with a fairly wide mouth, 42⅛″ across and 28⅜″ tall, but a short floor of 35⅜″ with the rear seats up. Fold them and it nearly doubles to 64⅝″, a gain of 29⅛″, which is where this boot earns its keep. It takes medium boxes and multi-package loads well, though the longest flat-packs, tall wardrobe frames and full bed rails, will not clear whether the seats are up or down. The floor narrows to 39¾″ at the back, so load the widest item first. The lip sits 28″ up with only a 1⅛″ drop to the floor, so expect a high lift then a flat slide.

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.
