The Grey Square-Quilted Medium Profile Innerspring Bed Mattress, model MAT-GRY-Q230-QN, is an unbranded rectangular sleep solution designed for versatile, long-lasting use across residential and commercial settings. Visually, it features a charcoal grey knitted polyester top cover finished with uniform 80mm square quilting, paired with a matching grey polyester side border detailed with diamond-quilt stitching set at 45mm pitch for a polished, structured look. Soft 50mm rounded corners soften its silhouette, while 120mm visible reinforced fabric webbing carry handles integrate seamlessly into the side panels, alongside stitched woven labels for care and fire safety information. Constructed for balanced durability and comfort, the mattress totals 230mm in profile, with a 25mm quilted top comfort layer made of polyurethane foam and polyester wadding, an 180mm tempered steel open coil support core, and a symmetrical 25mm non-slip grey polyester bottom padding layer. All perimeter seams are reinforced with stitched polypropylene tape to reduce edge sag, and the 2.3mm gauge coil core holds a static sleep load capacity of 360kg, with a pressure test cycle rating of 80000 cycles to support consistent long-term use. The comfort layer uses 25 kg/m³ density foam for a medium 6/10 firmness feel, with hypoallergenic ticking treated to resist dust mite and allergen buildup. The breathable quilted cover and open coil structure promote steady air circulation to cut down on heat retention during sleep, while the connected coil unit offers moderate motion isolation for shared sleep surfaces, and distributes body weight evenly across the full sleep area to reduce pressure points. Its symmetrical double-sided design allows regular rotation and flipping to prevent uneven wear over time, and the compressible core supports vacuum roll packaging for streamlined transport, requiring 72 hours of recovery time after unboxing. This queen-sized mattress, measuring 1530 x 2040mm, fits standard slatted, platform, or box spring bed frames, and works effectively for back and side sleepers. It is well suited for master or guest residential bedrooms, durable enough for children and teen bedrooms thanks to its abrasion-resistant stitched cover, aligned with 5-year use cycles for medium-term furnished rental properties, and meets basic durability and fire safety requirements for budget hotel standard rooms. Procurement teams should note the unit ships across 2 cartons with a total packaged gross weight of 130kg, requires 40 minutes of setup time per set, and is designed for use with bed frames using 15mm bent plywood or solid timber slats for optimal support.
