■①Size: Width 120cm x Depth 195cm x Thickness 20cm ②Product Weight: Approx. 19.38kg (Packaging Weight 21.73kg) ③Firmness: 180N, 32D High Density ④Surface Material: Knit Fabric, Filling: Non-woven Fabric, Pocket Coils, Wave Foam ⑤Avenco Original Patented Technology | SmartS Coil Coil Wire Diameter 1.8mm + 2.2mm (Firm springs are placed on the long edges) ⑥Reinforced sponge used at the four corners.

【Knit Fabric with Excellent Elasticity and Breathability】 It feels like sleeping on a cloud, not on springs. The soft top layer is made of premium knit fabric that resists pilling and wrinkling. The delicate cloud quilting and three-dimensional structure provide ample cushioning. Combined with fluffy urethane foam filling, it is gentle on the skin and offers excellent breathability and elasticity. The moment your body sinks in, it effectively reduces direct contact between the spring coils and your body, evenly distributing pressure.

【Deep Sleep, Edge Support, and Outstanding Stability】 A mattress can feel small if the edges sink in! This luxurious 20cm thick Deep Sleep mattress reduces tossing and turning, extending your deep sleep cycles. The long edges use three rows of firm 2.2mm diameter springs, so even sitting on the edge of the bed won't cause it to sink. This high-resilience mattress provides a feeling of firm support for your body and allows for smoother movement when turning over.

【Ultra-High Compression Ratio Coils | Pressure Dispersion Reduces Strain on the Body】 To achieve an unprecedentedly luxurious sleeping experience, we have created an ultra-high density, high compression ratio spring mattress. The 6.5-turn coil structure design features densely packed, durable coils that provide firm support, minimizing side-to-side motion, vibration from turning over, and squeaking sounds. With a 44% compression ratio, the springs, with twice the pressure resistance, achieve outstanding support. It conforms well to the body's curves, allowing areas where pressure tends to concentrate, such as the head, waist, and heels, to sink deeper, while the entire body makes close contact with the mattress, promoting a correct sleeping posture.
