Five locking heights lift the seat from 17 in to 25.5 in, so the same chair works for a short blind window and a tall shooting rail. Four telescopic legs handle the fine adjustment on sloped ground, and the wide duck feet on the ends grip gravel or sand rather than boring into it. The swivel base turns quietly through a full circle for a fast change of aim. Cushion, inclined backrest and padded armrests are built for waits measured in hours, and the reinforced triangular metal frame carries 330 lbs. Folded footprint is 21.5 in square and the chair stands 33.5 in to 42 in tall in use; net weight is 15.5 lbs with simple assembly out of the box.
