The CANYON Boulder XLCH01 is CANYON's "King Size" big-and-tall gaming chair, built with a noticeably heavier-duty spec than the rest of the range to suit larger or taller users, finished here in Grey fabric. Where CANYON's standard chairs (Wave, Flow) top out at a 120kg user weight, the Boulder XLCH01 is rated to 150kg, and it pairs that with a metal frame (rather than plastic), cold-molded foam padding, and a 5-star metal base — as opposed to the nylon bases used on the lighter models — rolling on five 60mm casters for a sturdier footprint. Height adjusts via a Class 4 gas lift, one class up from the Wave/Flow chairs' Class 3 lift, and the backrest reclines through a wide 90 to 160 degree range using a "Multiblock" tilt mechanism. It includes 4D-adjustable armrests, a 2D-adjustable lumbar curvature panel, and a magnetic-attach memory foam headrest pillow — none of which are fitted on CANYON's entry-level mesh chairs. Like the rest of the range it carries a 24-month manufacturer warranty, with a quick start guide and warranty card in the box.
