The 9-Zone Cashmere-Cotton Pocket Spring Hybrid Mattress (23cm Thick) features a clean white, tufted finish that complements a wide range of bed frame styles, with a structured layered layout designed to balance soft comfort and stable support. It delivers a medium-firm feel rated at 6 on the standard firmness scale, suited for both back and side sleepers seeking natural spinal alignment. Its construction starts with a 280g/sqm cashmere-blend knitted top cover with a quilted texture, lined with anti-dust mite treated non-woven fabric for a soft, skin-friendly sleep surface. The upper comfort layer uses 100% natural cotton wadding, with a non-woven polypropylene barrier separating padding from the core. The core consists of individually encased, heat-tempered pocket springs arranged across 9 distinct zones, with variable coil tension calibrated for the head, shoulders, lumbar region, hips, legs, and feet to deliver targeted pressure relief. Buyers can select from support layer fill options including high-density memory foam, 3E coconut coir, or natural latex to match preferred feel. A reinforced perimeter of high-density polyurethane foam prevents edge sag, while a high-resilience foam base with a non-slip finish anchors the mattress. Internal components work to enable strong motion isolation, reduce nighttime partner disturbance, and promote steady airflow through the dimpled tufted surface and porous knit cover to cut down on heat buildup. The king size variant fits standard platform beds, slatted frames, box springs, and electric adjustable bed bases, making it versatile for residential master bedrooms, guest rooms, and youth rooms, as well as mid-tier and budget hotel guest rooms, long-term rental apartments, and dormitory settings. It ships via vacuum compression that protects internal springs and foam layers during transport, packed across cartons for straightforward handling. Procurement teams and residential buyers should note the assembly time requirement, total packaged weight for delivery planning, and available fill variants to select the configuration that best matches end user firmness preferences for the intended use space. The unbranded model offers a durable hybrid build that balances comfort, support, and cost-effectiveness for high-traffic and long-term use settings.
