The material of this chair allows air to flow through an improvement over my last chair which was vinyl. The vinyl of the old chair flaked off which prompted me never to buy a vinyl-covered chair again. I think this chair will last longer. I like the light colors of the chair which also make it cooler. The seat does not have much cushioning and thus it is a bit hard but it is not uncomfortable. The size of the chair which is small is perfect for a smaller person. The rollers work well even on carpet. I thought the shortened arms might be uncomfortable but they are fine.
