The Quilted Knit Fabric Innerspring Queen Size Mattress (model MAT-Q220-BON, unbranded) is a residential innerspring mattress built for versatile, long-term use across everyday and commercial-adjacent settings. It features a clean rectangular form with a neutral beige finish, outlined by a structured 40mm thick side rail. Chevron quilting defines the top and bottom sleep surfaces, while textured woven polyester covers the side borders, accented by reinforced stitching and metal and woven identification labels. Four integrated carry handles are stitched to both long and short borders, trimmed with metal eyelets for durability during transport or adjustment. At 45kg net weight, the mattress presents a substantial, well-proportioned profile sized to match standard queen bed dimensions. Construction centers on a tempered steel bonnell innerspring core with 2.2mm wire diameter, encircled by high-density foam for stable perimeter edge support. Between the spring unit and comfort layers, a non-woven fabric barrier reduces friction and noise, while the comfort system consists of 32kg/m³ high-density polyurethane foam layered beneath the quilted cover. The top sleep surface uses breathable beige knitted polyester to support consistent air circulation through padding layers, and the symmetrical design features quilted padding on both top and bottom surfaces for dual-side use. Functional benefits include quiet operation with reduced motion transfer, thanks to the interconnected spring design and internal fabric lining. The foam encasement supports a 300kg edge load for stable seated use along the perimeter, and the knit cover offers tested abrasion resistance across 20000 cycles, paired with 45% foam resilience for balanced comfort. The mattress supports quarterly 180-degree rotation and flipped use to extend usable life, with a recommended 10-year warranty period. It holds a 300kg total static load capacity, suitable for individual sleepers up to 150kg or two combined sleepers. This model is appropriate for residential master bedrooms fitted with queen size frames, guest bedrooms for infrequent use, furnished long-term rental apartments, and mid-tier economy hotel guest rooms. It is compatible with all standard slatted, platform, and box spring queen bed frames; when used with slatted frames, slats should be 15mm thick bent plywood or solid timber with 80mm spacing, supported by six center support legs. Procurement teams should note the product ships across two cartons per set, with a total packaged gross weight of 130kg and 0.9m³ packaging volume, requiring 40 minutes of assembly per unit. The structure supports five controlled assembly cycles for installation or repositioning needs, making it suitable for both one-time residential setup and multi-unit furnishing projects.
