The MAT-HYB-DG300 hybrid innerspring mattress delivers a balanced, durable sleep solution suited for both residential and commercial settings, with a refined dark grey aesthetic anchored by crisp black perimeter detailing. Its top surface features a charcoal grey knitted polyester cover finished with hand-tufted construction and 30mm diamond quilt stitching, creating subtle 10mm indentations for a tailored, plush visual texture; 25mm radius corners soften its silhouette, and four stitched woven polypropylene carry handles sit flush at each corner to blend seamlessly with the 76mm wide black woven edge border. A side label is positioned 152mm from the bottom edge for clear, unobtrusive product identification. The queen size model measures 1524 x 2032 x 305 mm, structured around a zoned support core of 13.5 gauge individually pocketed steel coils that makes up 229mm of the total profile, topped with a 76mm Euro top comfort system. The top cover is quilted with 20mm high-density polyurethane foam, underlain by a 30mm charcoal-infused memory foam layer and 25mm high-density support foam; the perimeter is encased with 50mm high-density foam under the black woven border, and the base uses a black non-slip woven polypropylene fabric to grip bed foundations. Hand-tufted with polyester ties, the internal layers are secured to prevent shifting over time, while 38mm wide double-stitched corner handles support 90kg of pull load each for easy handling. Functionally, the medium-firm mattress (rated at 32 ILD for foam layers) offers targeted pressure relief by contouring to shoulders, hips, and the spine, with 80% motion reduction from pocketed coils to cut down on partner disturbance. The foam-encased edge eliminates perimeter sink to preserve the full usable sleep surface, while charcoal-infused foam wicks moisture and reduces odor buildup; air channels through the coil core and breathable knit cover support consistent airflow for temperature regulation. The total static load capacity reaches 454kg for two sleepers, with a recommended weight limit of 136kg per person, and the surface fabric resists abrasion through 50000 double rubs for long-term use. This mattress fits queen size platform beds, slatted foundations with 15mm bent plywood or solid timber slats, and adjustable bed bases, making it ideal for residential master bedrooms, guest rooms, and high-turnover hotel hospitality upgrades; its medium firmness accommodates back, side, and combination sleepers, as well as couples sharing a sleep surface. For procurement, note that each set ships across two cartons with a total packaged gross weight of 130kg and total packaging volume of 0.9m³, requiring 40 minutes of assembly per unit; select foundations that meet the slat thickness specification to preserve long-term performance, and account for two-person handling during delivery and setup due to the 43kg net weight of the queen size mattress.
