This will depend on your preference and where you plan to put your chair. Natural fabric, such as linen or cotton, is great for indoor use. It’s breathable, soft to the touch, and durable. But it’s not great with stains. Leather is a great natural fabric since it’s durable and stain-resistant, but it can get hot. Finally, there are synthetic fabrics made for indoor and for outdoor chairs and furniture. If you have decision paralysis, feel free to ask your Tasker for advice.
