Technical specifications for the Superjare Drafting Chair include an SGS-certified Class-3 pneumatic cylinder with a stroke range of 23.6 inches to 32.2 inches. The chassis is constructed from reinforced nylon composite, providing vibration dampening and a static weight rating of 400 lbs. A 360-degree swivel manifold is integrated into the seat mounting plate.
Material analysis identifies the backrest as a breathable mesh module. The footrest ring is secured via a manual compression knob; maintenance protocols recommend periodic degreasing of the center pole with isopropyl alcohol to maintain the friction coefficient. The armrest module features a flip-up design but does not provide lateral width adjustment.
Real-world service life analysis suggests an optimal performance load under 250 lbs to ensure smooth pneumatic extension over long-term deployment.
Performance metrics show that the standard hard-plastic casters lack a locking mechanism. The footrest ring diameter is fixed, which may limit ergonomic positioning for users with longer lower-limb dimensions. Height compatibility is rated for work surfaces between 36 and 42 inches.
The Adjustable Drafting Chair with Foot Rest - Black provides a higher 400lb static rating as an alternative to budget stools with 250lb limits.
This unit is grouped with standing desk stools and drafting chairs for professional use.
