This grey button-tufted medium profile hybrid mattress, model MAT-GRY-TFT-250-AIR, is an unbranded sleep solution built for consistent comfort and long-term durability. Its visual design features a soft quilted grey knit fabric top surface, accented by evenly spaced button tufts arranged in a 6 row by 6 column grid secured with white fasteners. The smooth rounded 50mm radius corners are finished with 20mm wide reinforced grey woven polyester edge tape, while the full-perimeter 3D perforated grey mesh side border creates a streamlined, functional profile with 8mm ventilation holes to support airflow. A discreet 80mm by 50mm coated fabric identification tag is affixed to the side for clear product reference. The king size reference model measures 1800mm wide, 2000mm long, and 250mm thick, with a total finished weight of 45kg. Constructed with a layered hybrid design, the mattress features a 13.5-gauge tempered open coil innerspring core, separated from upper comfort layers by a 20mm bonded polyester insulator pad. A 30mm high-resilience polyester fibre comfort pad sits above the insulator, topped by the quilted grey knit polyester cover. High-tensile braided polyester twine runs through all internal layers to secure each tuft, with 15mm diameter securing points for each fastener. The cover fabric delivers 30000 Martindale cycles of abrasion resistance, and the unit holds a 350kg static uniform load capacity, supporting up to 120kg per user with a medium firmness rating of 6 out of 10, for a rated 10-year design service life. Core functional benefits include stable layer alignment that prevents internal material shift with extended use, continuous perimeter air circulation that reduces trapped heat, reinforced edges that resist sagging when seated, even weight distribution that minimizes pressure points, and an insulator layer that reduces coil noise during position changes. The breathable cover and mesh border also wick away surface moisture for cooler rest, and the compressible core supports vacuum-sealed rolled packaging for easier transport and setup, requiring 72 hours to fully expand after unboxing. This mattress is suited for residential master bedrooms paired with standard king size bed frames, guest rooms where its medium firmness accommodates diverse sleeper preferences, rental properties where its durable construction stands up to multi-tenant turnover, and standard adjustable bed frames, with a single size variant compatible with bunk and loft bed safety rail requirements. Procurement teams should note the mattress ships as one set split across two cartons, with a total packaged gross weight of 130kg and 0.9 cubic meters of total packaging volume, requiring 40 minutes of assembly time per unit. All purchases should align with relevant size variants to fit intended bed frame dimensions.
