The 132# Firm Eco-Friendly Coir Palm Mattress with Knitted Quilted Cover (model CM-132-Knit-Hard-Coirmattress) is an unbranded thin hard palm/coir fiber mattress designed for consistent, supportive use across residential and institutional settings. Visually, it features a streamlined low-profile slab form, finished with a herringbone knitted quilted cover stitched in 80 x 40 mm pattern units, accented by 40 mm wide reinforced woven polyester edge binding, a stitched woven fabric brand patch, and a transparent PVC side label pocket for a neat, tailored appearance. It is constructed in layered build: the top sleeping surface uses 220gsm herringbone knitted polyester fabric quilted over a 20mm 35kg/m³ high-density polyurethane foam comfort layer, separated from the 90kg/m³ hot-pressed 3E eco coir fiber core by a 20gsm non-woven polyester felt protective interlayer, with no moving metal components in its structure. The mattress delivers uniform firm flat support rated 75 N on the 100firmness scale to promote spinal alignment for back sleepers, with a recommended static sleep load capacity of 300 kg and expected core service lifespan of 10 years. The removable zippered cover supports separate cleaning, while the breathable coir core and knit cover offer a moisture vapor transmission rate of 2500 g/m²/24h to reduce moisture buildup; the cover fabric resists abrasion up to 12000 Martindale cycles, and the squeak-free low-noise construction eliminates disruptive sound during use. Fold-compatible variants support a 200 mm minimum bend radius, and the product fits standard platform beds, tatami frames, slatted bed bases (designed for use with 15 mm bent plywood or solid timber slats, secured with M8–M10 bolts with at least two fixing points per corner to support up to 5 controlled assembly cycles) and bunk beds. It suits adult, elderly and children’s bedrooms requiring firm back support, student dormitory bunks, low-profile tatami platforms, temporary floor placement for guest use, and cost-effective durable furnishing for long-term rental units. Available core thicknesses reach 100 mm, with the maximum overall dimension of 1800 x 2000 x 100 mm weighing 35 kg; standard widths span 900 mm to 1800 mm and lengths reach 2000 mm, with custom dimensions available on request for non-standard frames. For procurement, note that each set is packaged across cartons with 0.9 m³ total packaging volume and 130 kg packaged gross weight, requiring 40 minutes of assembly time per unit; specifiers should confirm required thickness, standard or custom dimensions, and fold variant suitability for intended installation frames before ordering, aligning with the 400 kg static load reference for supporting bed structures.
