Product Description

The Youwei SM303 Latex Cotton Blend Triple-Protection Mattress is an innerspring hybrid model tailored for consistent, medium-firm support across varied residential and hospitality settings. Visually, the mattress features a refined vertical stripe knitted polyester top cover and matching striped side border finished with reinforced piping, accented by galvanized steel tufting buttons that anchor its layered internal structure for a tidy, tailored look that complements both classic and contemporary interior schemes. The tufted surface construction secures all internal fill layers in place to eliminate shifting during regular long-term use, while the 40 mm thick side rail delivers a clean, defined profile suited to most standard bed frame designs. Built for durable, balanced performance, the mattress uses a tempered steel bonnell innerspring core with zoned tension variation to support proper spinal alignment, paired with a natural latex and cotton blended top comfort layer and high-resilience polyurethane foam quilted fill for responsive, cushioned support. High-density polyurethane foam encasement forms the edge support system, preventing edge sag when users sit on the bed perimeter. The non-slip woven polyester bottom cover keeps the mattress stable on compatible bed bases, while the air-permeable knit side border promotes consistent internal air circulation. The triple-protection fabric finish delivers stain-resistant, anti-mite, and anti-moisture surface performance, making the mattress well suited to humid regional climates. A king size unit measures 1800 x 2000 x 250 mm, with a static load capacity of 350 kg and per-side recommended user weight of 150 kg. For residential use, the mattress is an ideal fit for master bedrooms outfitted with king size bed frames, and works seamlessly with platform beds, slatted frames, and adjustable bed bases. It is also appropriate for furnishing mid-range hotel guest rooms, serving adult users who prefer balanced, medium-firm support. Procurement teams should note that units ship with 55 kg net weight, packaged across 2 cartons with a total packaged gross weight of 130 kg, requiring 40 minutes of assembly time per set. When selecting a supporting foundation, ensure slat spacing does not exceed 75 mm; a foundation with 6 center support legs is recommended for long-term structural performance. The main structural joints support 5 controlled assembly cycles for ease of installation and repositioning.
