The Paihuai Shenghuo SM306# 9-Zone Latex Pocket Spring Mattress is a premium bedding solution designed for balanced comfort and long-term durability. Visually, it features a soft grey skin-friendly knitted polyester top cover finished with geometric quilted stitching, paired with a dark grey woven polyester mesh side border fitted with ventilated panels for a streamlined, understated aesthetic that complements a wide range of bed frame designs. Constructed with layered, purpose-built materials, the mattress integrates a 22mm high-resilience polyurethane foam quilt padding beneath the top cover, a natural latex comfort layer with an open-cell breathable structure, non-woven fabric separation layers to isolate material components, and a core of individually wrapped pocketed springs arranged in a 9-zone ergonomic layout. A high-density polyurethane foam encasement reinforces the full perimeter for edge support, with all quilted seams secured using high-tenacity polyester thread at a consistent 30mm pitch. The king size model measures 1800 x 2000 x 220 mm, with a 40mm thick side rail, and is rated medium firm at 6/10. Functionally, the mattress delivers targeted support through variable spring tension that aligns the spine and relieves pressure on the shoulders, hips and lower back. The open-cell latex and knitted cover promote consistent air circulation to regulate temperature and reduce overheating for year-round comfort, while individually wrapped springs minimize motion transfer between sleep partners. The reinforced foam perimeter prevents edge sag when sitting on bed sides, and the natural latex layer resists dust mites and bacterial growth for a hypoallergenic sleep surface. The mattress arrives fully assembled for immediate placement, and its reversible two-sided design extends usable service life. It has a static load capacity of 600 kg, supports a maximum of 150 kg per sleeper, and meets durability standards for high-frequency use. This mattress is well suited for residential master bedrooms paired with king or queen size platform beds, slatted frames or box springs, as well as guest bedrooms where its medium firmness caters to a broad range of sleeper preferences. It is also appropriate for hotel and serviced apartment settings, and delivers tailored pressure relief for both back and side sleepers across all seasons. For installation with slatted frames, use slats with 15mm thickness made of bent plywood or solid timber, maintain 80mm slat spacing, and fit 6 center support legs for optimal structural performance. Procurement teams should note each set ships across multiple cartons, with a total packaged gross weight of 130 kg and total packaging volume of 0.9 m³ per set, to plan appropriate handling and delivery logistics.
