The Shimes Chevron Quilted Hybrid Innerspring Mattress, model SM-CHV240-Q, is a rectangular sleep surface designed for versatile, long-term use across residential and light commercial settings. Its visual profile features a crisp white chevron-quilted knit top panel paired with a dark grey woven mesh side border, accented by smoothly reinforced sewn corners and integrated woven webbing carry handles positioned along the sides, with a stitched synthetic brand label mounted on the border for understated branding. The mattress follows a standard queen size footprint, with a structured perimeter that sits flush to compatible bed frames without requiring additional under-frame clearance. Its construction layers a 20mm high-density polyurethane foam comfort section directly beneath the quilted top, over a core of 1.3mm gauge steel Bonnell innerspring coils, with an optional 20mm coconut coir fiber support layer available for tailored firmness. Perimeter edges are stabilized with sewn fabric binding and foam edge support to reduce sinkage when sitting or sleeping near the mattress edge, while the isolated spring design minimizes movement transfer and associated noise during use. The product offers dual-firmness, double-sided functionality, with a softer feel on the quilted top surface and a firmer feel on the reverse to suit varying sleep preferences. Integrated reinforced carry handles support safe two-person lifting and positioning, and the mattress is compatible with standard platform, slatted, and box spring bed frames, including low-profile platform designs that do not use a separate box spring. Regular rotation 180 degrees every three months is recommended to extend usable service life. This mattress is well suited for residential master and guest bedrooms outfitted with queen size frames, long-term rental property furnishing, and general hotel or homestay guest accommodation, with an even weight distribution design built to support two adult sleepers. Its medium firm feel, rated 6 out of 10, caters to a broad range of general sleep preferences.
