It's simple, the bigger the rug the heavier it gets, at 3.2 kgs per sq meter just a 3 by 2 meter rug can weigh 18kgs, thats roughly what a fully packed suitcase. So when it comes to large rugs, please bare this in mind.
Imagine when you're buying a 17 x 4.5 meter rug (the largest rug we've ever sold) . Well it weighed in at 230kgs and took 8 people to lift.
If you decide to buy a large rug of then consider the weight it might be.
