Hybrid Pocket-Spring Mattress – 30cm Deep Comfort (20cm Pocket Core + Memory Foam)

The WSM-110 is a premium 30 cm hybrid mattress engineered for Australian bedrooms — combining a 20 cm, 2.0 mm wire pocket-spring support system with a multi-layer comfort stack that includes zero-pressure memory foam, high-hard support foam and targeted massage foam. Finished in a light-grey, 450 g high-end knitted fabric cover with the “Three Defense” logo and an anti-slip base, WSM-110 balances pressure relief, breathability and long-term support for couples and single sleepers in Perth’s climate. The model identifier “wsm110” is visible on the internal diagram for easy reference.

What You Need To Know

• Total depth: 30 cm (nominal).
• Support core: 20 cm high pocket springs using 2.0 mm wire for zoned responsiveness and reduced motion transfer.

Special Features

• Deep pocket-spring core (20 cm, 2.0 mm wire): Individually pocketed springs support the spine where it needs it and isolate movement so partners sleep undisturbed. This spring depth also improves airflow through the mattress for a cooler feel.
• Multi-layer comfort system: A layered stack (massage foam → super soft foam → zero-pressure memory foam → high-hard foam) gives immediate plushness plus long-term structural support and pressure relief.
• Targeted massage foam layer: The 2.5 cm massage foam helps stimulate gentle surface responsiveness and a micro-bounce that complements the memory foam contouring.
• Premium finish & safety: Heavy-weight 450 g knitted fabric cover, light-grey aesthetic, visible model tag (“wsm110”) and anti-slip backing for stability on slatted or solid bases.
• Hygienic & modern branding: “Three Defense” logo signals a focus on easy care and a clean finish ideal for contemporary Perth homes.

Product Details

• Model: WSM-110 (diagram labeled “wsm110”)
• Construction: Hybrid — foam comfort layers on a 20 cm pocket-spring core.
• Comfort profile: Medium-to-medium-firm — the memory foam offers contouring while the substantial spring core provides strong lift and edge stability (well suited for back and combination sleepers and couples).
• Temperature performance: Deep spring core plus breathable knitted cover and layered non-woven interfaces promote airflow, helping manage warmth in Perth’s summer months.
• Finish options: Light grey cover with “Three Defense” logo (as pictured).
• Depth & weight: 30 cm nominal depth; weight varies by size and packaging.

Care & Maintenance

• Use a fitted mattress protector to guard against spills, dust mites and sweat — the simplest way to extend mattress life.
• Rotate mattress head-to-foot every 3–6 months if recommended on the product tag (helps even wear across layers).
• For surface spills, blot immediately with a clean, barely damp cloth and mild soap; avoid saturating foams. Allow thoroughly to air dry before remaking the bed.
• Vacuum the cover occasionally with a soft upholstery nozzle to remove dust. Keep bedroom humidity reasonable and allow airflow to reduce condensation and mould risk — important in WA’s variable climate.

Sustainability

WSM-110 blends durable, higher-density memory and support foams with eco-friendly felt and non-glue cotton layers to reduce adhesive use, extend mattress lifespan and lower long-term waste — a pragmatic, more sustainable choice for Perth households.
