The Valido Series features extra-thick worksurfaces that combine the durability of laminate with a decidedly upscale impression. Precise ribbon profile on all edges adds a distinctive touch and designer detail. Mahogany laminate over 1-1/2" thick, solid-core, high-performance particleboard is scratch-resistant and stain-resistant. Cord-management grommets for routing and hiding wires and cables are located in the tops of desks and return shells. Drawers operate on a long-lasting, ball-bearing suspension. File drawers store letter-size (front to back) or legal-size (side-to-side) hanging files with a maximum height of 9-3/4" and have full extension. All drawers offer five-sided construction for easy drawer alignment. Furniture is certified by SCS to be in compliance with specific, indoor, air-quality emission requirements and meets or exceeds applicable ANSI/BIFMA standards.
