The number of Adirondack chairs for a fire pit depends on the size of your fire pit sitting area. I’ve seen fire pits as intimate as just two chairs, while large fire pits areas may have 6. With Adirondack chairs and a fire pit, the important thing is to provide adequate space. Set each chair 2 to 3 feet apart to fully enjoy them. These chairs, with their laid-back orientation, are a little trickier to get in and out of. When in doubt, be more generous with your spacing. In addition, allow approximately 32 inches of space between the fire pit and your chairs. Measuring the sitting area radius ahead of time will tell you how many chairs you can have.
