Product Description

The JUESHANGDA Fully Upholstered Compact Angular Tub Lounge Armchair, model LNG-TUB-085, features a modern geometric aesthetic defined by its angular tub silhouette, wrap-around enclosure, legless low-profile base, and monochrome finish options. Its 360-degree fully upholstered construction creates a cohesive, streamlined appearance, while the wide enclosed base delivers a low center of gravity for stable visual balance that supports close side-by-side grouping without visible gaps between units.
Built for durable long-term use, the chair’s internal frame uses 18mm thick engineered wood panels, paired with a 14mm bent plywood seat support board, 2mm sinuous spring grid seat layer, and 5mm hardboard base panel. All seams are constructed with double-stitched bonded nylon thread at 8 stitches per inch, while non-marking plastic glides line the base to protect floor surfaces. The outer upholstery is woven polyester tech fabric rated for 50000 abrasion cycles, with a fixed attached seat cushion filled with high-resilience polyurethane foam, and back and armrests padded with medium-density polyurethane foam. The finished unit weighs 18 kg, supports a 200 kg static load, and measures 850 x 875 x 835 mm overall, with a 420 mm seat height, 680 mm seat width, 580 mm seat depth, 415 mm backrest height, and 200 mm armrest height, resting on a 790 mm wide by 820 mm deep base footprint.
Designed for flexible single-person seating, the freestanding legless design supports versatile arrangement, while the surface-cleanable upholstery simplifies routine upkeep. It is suited for a wide range of public and private spaces, including office reception lobbies for formal guest waiting, hotel lounge bars and break areas for clustered casual seating, residential living rooms, reading nooks and bedrooms as accent seating, coworking break zones for informal team discussions, exhibition and event spaces for temporary event seating, and library quiet zones for individual reading use.
For procurement planning, each unit ships in 2 cartons with a 23 kg packaged gross weight and 0.26 m³ total volume, requiring 40 minutes of assembly per set. A 20GP container holds 135 sets at 85% space utilization, supporting efficient bulk ordering for large-scale furnishing projects.
