The Kensington K56152US features a rigid polymer chassis integrated with a 40kg/m³ high-density viscoelastic polyurethane slab. Technical specifications list a multi-stage height adjustment range of 3.5 to 5 inches, utilizing a reinforced peg-and-groove locking mechanism. Unlike all-foam models, the reinforced plastic frame prevents the unit from bottoming out under a standard 50lb resting force.
Material analysis confirms the cover is removable and machine-washable for extended hygienic service life. The tilt range is manually adjustable up to 20 degrees, supporting active lower-limb movement. The proprietary SmartFit system provides a standardized color-coded method for height calibration based on user-specific ergonomic requirements.
Audit note: Structural tension during the locking of height pegs may produce an audible snapping sound; this is indicative of plastic seating rather than structural failure.
For users who do not require a rigid height-adjustable frame and prefer a purely soft footprint, the Everlasting Comfort Cloud model offers a foam-only alternative.
This unit is a standard comparative model in the ergonomic foot rests classification.
