KERTE presents the Armless Upholstered Modular Lounge Chair with Caster Base, model LC-MOD-ARMLESS-CASTER-01, a versatile seating solution designed for flexible modern spaces. The chair features a clean, boxy silhouette with a fully upholstered base that creates a streamlined low-profile look, with only caster legs exposed below the seat body. Its armless, flat vertical side panels allow seamless adjacent placement with identical units, enabling custom linear seating banks and tailored layout configurations. Constructed with a woven polyester fabric outer upholstery with a matte finish, the chair has sewn fabric joints with matching thread for a polished, uniform appearance across all padded surfaces. The seat cushion uses a polyurethane foam core with fiber wrap, while the backrest is padded with polyurethane foam and a fabric backing for structured comfort. An internal support frame of plywood or solid wood forms the structural foundation, paired with a wood or particle board inner base shell wrapped in fabric for rigidity. The chair sits on chrome-plated steel cylindrical stem legs fitted with black nylon twin-wheel casters, enabling smooth movement across hard floors and low-pile carpet. Functionally, the chair delivers fixed upright torso support with a non-adjustable backrest angled to ergonomic lounge standards, suited for short-duration seating. Its caster base supports easy repositioning, making it ideal for spaces that require frequent layout changes. The fabric cover is replaceable to support refresh or reconfiguration needs over time. This modular chair fits a wide range of commercial settings. It serves as visitor seating in office reception areas and corporate lobbies, casual seating for open-plan office breakout zones and impromptu collaboration, and durable seating for high-traffic educational facility common areas including school lounges and library reading nooks. It also works well as flexible building blocks for co-working space seating layouts, and as cleanable individual seating for healthcare facility waiting rooms. For procurement planning, each unit packs in a single carton with caster hardware and protective padding, with an assembly time of 30 minutes for installing caster legs to pre-threaded base inserts. The chair supports a maximum user weight capacity of 110 kg, aligned with standard static load ratings for single-seat upholstered lounge chairs. Teams should confirm exact material specifications, caster braking functionality, and connecting hardware avlability directly with the supplier to align with specific project requirements.
