The De Rucci DR-MID-180200Charcoal Top Grey Side Quilted Hybrid Pocket Spring Mattress is a mid-profile sleep solution designed for balanced comfort and long-term durability. The mattress features a distinct two-tone aesthetic, with a dark charcoal knitted polyester top panel and light grey vertical-ribbed knitted polyester side panels. The top panel incorporates evenly spaced quilted channels, secured by channel stitching, while woven polyester piped trim lines all edges, paired with softly rounded corners for a polished, finished appearance. Constructed as a hybrid innerspring model, the mattress uses a core of tempered steel independent pocket springs, surrounded by a reinforced high-density foam perimeter encasement to support the bed edges. Above the spring core sits a layer of high-density polyurethane comfort foam, topped with polyester fiberfill batting held in place by the quilted cover stitching. All internal layers are bonded with low-VOC water-based lamination adhesive. The knitted fabric cover supports consistent air circulation through both top and side panels for breathable performance, and the single-sided design removes the need for regular flipping during use. The individually wrapped pocket coils isolate motion transfer between sleepers to reduce disturbance from overnight movement, while the reinforced foam perimeter prevents sagging when users sit on the bed edges. The medium firmness rating suits a wide range of sleep preferences, and the mattress is compatible with standard King size platform beds, slatted frames, adjustable bases, and box springs. It is built for vacuum-compatible roll-packing to support compact, efficient shipping. This mattress is well-suited for residential master bedrooms serving as a primary sleep surface for two adults, as well as furnished apartment and rental units thanks to its durable construction and broadly appealing firmness level. It is also appropriate for mid-tier hotel guest room installations, with standard 10-year warranty coverage, and works seamlessly with powered adjustable bed frames due to its flexible spring core. Its breathable knit cover supports comfortable use across warm and cool seasons. When procuring this model, buyers should note it ships across cartons per set, with an assembly time of 40 minutes per unit. Teams should confirm slatted bed frames used with the mattress have slat spacing within the recommended maximum for even support, and account for the packaged gross weight and total packaging volume when planning receiving and storage workflows. The abrasion-resistant cover fabric is engineered to withstand repeated regular use for extended service life.
