Regarding the shipping carton which, it seems, scared some people, mine came in a box whose dimensions were: 66x52x22 cm. He could indeed contain 2 or 3 mats of this type (placed diagonally), but its volume was reasonable. This can vary from one shipment to the other, but no need to take a van if you go for it somewhere!
I do not put 5 stars because the carpet was delivered slightly damaged, or it was rolled too tight, which had the effect of digging / stretch in the heart of the roll, or when heavy objects were stored above (and this not from the carrier because the cardboard was intact). Never mind, it's still acceptable to me, and for a carpet at this price, these impairments were superficial, only aesthetic, but they are important enough to be mentioned. They do not affect the actual quality of the carpet, that is, we repeat, excellent!
