The chair system generally includes a tubular frame that releasably engages a flexible seat. The tubular frame includes a front hub and a rear hub spaced one from the other by a cross bar, plus front and rear footings which stabilize the chair system on the ground or undersurface. A V-shaped upper support extending from the front hub supports and holds open the leg portion of the flexible seat, while the trekking poles are releasably engaged with and extend upwardly from the rear hub to support, and hold open and upright the back portion of the flexible seat. ## Claims ### Claim 1 A hiking system including: A. A tubular frame including a front hub and a rear hub; B. A pair of upper supports releasably engaged with said front hub; C. A flexible seat releasably engaged with said pair of upper supports; and D. A pair of trekking poles each including a substantially pointed distal tip, said pair of trekking poles releasably engaged with said rear hub by lowering said distal tips into said rear hubs. ### Claim 2 (depends on 1) The hiking system of claim 1 wherein said pair of trekking poles is releasably engaged with said flexible seat. ### Claim 3 (depends on 1) The hiking system of claim 1 further including a plurality of front footings extending downwardly from said front hub. ### Claim 4 (depends on 3) The hiking system of claim 3 further including a plurality of rear footings extending downwardly from said rear hub. ### Claim 5 (depends on 4) The hiking system of claim 4 further including a cross bar spanning said front hub and said rear hub. ### Claim 6 (depends on 1) The hiking system of claim 1 wherein each trekking pole of said pair of trekking poles includes elongation segments having a telescoping orientation. ### Claim 7 (depends on 6) The hiking system of claim 6 wherein at least one of said elongation segments includes an end cap. ### Claim 8 (depends on 7) The hiking system of claim 7 wherein said end cap defines a longitudinal channel. ### Claim 9 (depends on 6) The hiking system of claim 6 wherein each trekking pole of said pair of trekking poles includes at exactly two elongation segments. ### Claim 10 A chair system including: A. A flexible seat forming a back portion and a leg portion; B. A tubular frame for stabilizing said flexible seat, said tubular frame including a rear hub; and C. A pair of adjustable length trekking poles each including a substantially pointed distal tip, said trekking poles releasably engaged with said flexible seat, wherein said pair of trekking poles is releasably engaged with said rear hub by lowering said distal tips into said rear hub. ### Claim 11 (depends on 10) The chair system of claim 10 wherein a total packed volume without trekking poles is approximately 12.75″×2.5″×3.5″. ### Claim 12 (depends on 10) The chair system of claim 10 wherein a total weight is approximately 14 oz. ### Claim 13 (depends on 10) The chair system of claim 10 wherein said trekking poles are adjusted to a substantially fixed length. ### Claim 14 (depends on 10) The chair system of claim 10 wherein said trekking poles include two elongation segments. ### Claim 15 A method of assembling a chair system including the acts of: A. Unfurling a tubular frame and allowing a shock cord to align interconnected components; B. Engaging adjoining said components one to the other; C. Removing handles from trekking poles; D. Releasably engaging proximal ends of said trekking poles with a flexible seat; and D. Releasably engaging distal ends of said trekking poles with a rear hub fixed to said tubular frame by lowering assembled trekking poles tip-first into said rear hub. ### Claim 16 (depends on 15) The method of claim 15 further including the step of employing trekking poles having exactly two elongation segments. ### Claim 17 (depends on 15) The method of claim 15 further including the step of employing trekking poles having a substantially fixed length. ### Claim 18 (depends on 15) The method of claim 15 further including the step of storing said tubular frame and said flexible seat in a stuff bag.
