SEA TO SUMMIT Air Chair Nylon Regular ST81195 ……… Purchased in 2022. Used during tent stays on mountain climbs. By slightly deflating and folding an air mattress, and then setting up this item, it becomes a simple chair. I used it only once during a rain delay in the tent, but recently I haven't been taking it due to efforts to lighten my load, so I am selling it. ……… ★ Immediate purchase OK. ★ Air mattress not included. An air mattress is required for using this item.
