The Large/Tall Counter-Height Lab Stool provides a deeper, more spacious seating surface for users who need additional upper-leg support at elevated workstations. The 20″ W × 21″ D seat offers a roomier fit ideal for taller users or anyone who prefers extra depth during extended periods of seated work. The fully upholstered 17″ W × 19″ H dual-curve backrest supports natural spinal alignment, while the counter-height pneumatic range of 24.5″ to 31″ allows easy positioning at lab benches and clinical counters. A 2.5″ sliding seat depth lets users personalize leg support for optimal comfort. Base model comes without arm rests. Designed for hygienic and technical environments, this stool includes a 20″ adjustable foot ring to promote proper lower-leg posture at elevated surfaces. Durable vinyl upholstery wipes clean quickly, and urethane dual-wheel casters provide smooth mobility, with optional locking casters available for added stability during precision tasks. The reinforced nylon base ensures lasting durability, and included width plates allow armrests to be added when upper-body support is preferred. This Large/Tall model offers deep seating, excellent adjustability, and reliable ergonomic support for users who require more space at counter-height workstations.
