Sizing up Dubai.

If visitors get tired while exploring the ice rink, aquarium and more than 1,200 stores in the Dubai Mall, it’s good to know that the world’s largest mall is outfitted with one of the world’s most comfortable chairs. The Gas Chair was designed by Jesus Gasca for Stua, and there are more than 2,000 of them in the mall, which has impressive views of Burj Khalifa, the world’s tallest building.
