About the Mercedes Benz A-Class 2019 boot
The A-Class gives you a hatchback boot with a modest mouth, 37″ wide and 28¾″ tall. The floor runs 32¼″ with the seats up and nearly doubles to 59½″ folded, a 27⅛″ gain that is this boot's strongest card. It narrows to 39″ at the back, so wide flat-packs sit better on the diagonal. The load lip is fairly high at 25⅝″ with a 4⅜″ drop to the floor, so lift heavy boxes in rather than drag them. Short and medium cartons go in seats up; long bed and wardrobe frames need the fold, and the very longest need a roof rack. Fold the seats before you load.
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.
