The frame here is aerospace-grade 7075 aluminum alloy, the same family of alloy used where strength has to come without weight, and it is what lets a heavy-duty rustproof chair weigh only 4 lbs in total. Holding it steady is a unique double-triangular structure that braces the legs against each other in two planes at once, so the chair stays planted and setup stays hassle-free. That setup takes seconds and needs no tools at all: unfold the frame legs, then drop the seat onto them. Large footpads at the base of each leg spread the load so the chair neither slips on a hard surface nor sinks into soft ground. The seat is the other half of the design, cut in an ergonomic moon shape that conforms to the body, with a high back and wide seat paired with a built-in pillow so head and shoulders have somewhere to rest instead of hanging over the rail. It sits 16 in from the ground and the open chair measures 24 in by 33 in by 39 in overall. Fabric is thick 600D oxford with reinforced corners at the load points, and mesh panels are worked into the seat to enhance air circulation so a long sit stays breathable and non-stuffy. A side storage pocket keeps small items within reach. Packed, everything goes into the compact carrying bag at 17 in by 7 in by 7 in, light enough to strap to a pack, which makes it suitable for camping, backpacking, hiking, travel, and indoor lounge use alike. It comes in black.
