GUOYOU CC-PP-SL-001 is a padded polypropylene back sled base conference chair categorized as a conference/guest stacking chair. Its visual form features a matte off-white one-piece injection-molded polypropylene backrest shell with a central rectangular cutout and an integrated horizontal polypropylene lumbar support panel, paired with a contoured matte off-white polypropylene seat shell upholstered in light gray woven fabric. The chair sits on a chrome-plated tubular steel sled base with a continuous bent wire form and rectangular front and rear cross runners, creating a sleek, streamlined profile suitable for modern commercial interiors. In terms of construction and materials, the backrest and seat shells are made of injection-molded polypropylene, with the seat shell supporting a padded cushion composed of high-resilience polyurethane foam covered in light gray woven polyester fabric stitched along the perimeter. The sled base is constructed from chrome-plated low-carbon tubular steel, connected to the seat shell via black injection-molded glass-filled polypropylene brackets. Integrated plastic glide pads at the base of the sled runners provide floor protection. Practical functions include vertical stacking capability, where chairs nest vertically when lifted from the front with sled legs fitting over the rear frame of lower chairs. It has a fixed seat height with no adjustment mechanism, integrated lumbar support from the contoured horizontal panel in the backrest opening, and an armless design that allows unobstructed side access and closer positioning to table edges. The central backrest opening improves r circulation for extended sitting, while the lightweight build enables single-hand carrying for room reconfiguration. The plastic glide pads on the sled base reduce scratching on hard flooring surfaces. This chair is suited for a wide range of commercial and residential spaces. It works well in conference rooms and boardrooms with flexible seating layouts, training centers and seminar rooms that require frequent reconfiguration, office reception lobbies and visitor waiting areas with high traffic, staff cafeteria and break areas with regular cleaning needs, and open-plan workstations as guest seating beside individual desks. For procurement, buyers should note that material details including exact resin grade, foam density, fabric composition, fire ratings, tube wall thickness, and chrome plating thickness require confirmation from the supplier’s bill of materials. Assembly time per chair is for attaching the seat pad if shipped separately, and loading quantities for contners are based on nested stacking configurations. Exact product specifications and performance data should be verified against supplier-provided datasheets and sample testing before final purchase.
