Will MARKUS Office chair, Vissle dark gray, Medium fit in a Mercedes Benz A-Class 2019?

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.

The MARKUS chair travels as a single box of 38½″ × 24¼″ × 9½″, short enough to lie flat in most trunks without folding a seat. The catch is density: 49 lb 6 oz packed into that footprint, so the box is far heavier than its size suggests. There is no long dimension to fight, which makes this an easy load for a sedan or hatchback, and an SUV will not notice it. Treat it as a two-person lift anyway, slide it over the sill on its long edge instead of carrying it flat, and load it last so the weight sits near the opening when you unload.
