When looking for outdoor chairs, you want them to be lightweight and portable. You also want a good storage or travel bag to carry them in. A good outdoor chair can be used for the beach, tailgates, camping or backpacking (when you don't want to sit on the rocks!).
The load should be good as well because as a society, we're getting heavier. This is not really a good thing health-wise but it's the truth. Some of the chairs are more expensive than other chairs but you get what you pay for. The load should be at least 250 pounds and the chairs should be stable.
Here are some chairs that were popular in 2018 and will undoubtedly be popular in 2019 as well.
