Special Features

• 18 cm pocket-spring core (2.0 mm wire): Individually pocketed springs give zoned support, strong edge lift and superior motion isolation for couple-friendly sleep. Pocket springs also promote airflow through the mattress for a cooler sleep surface compared with dense all-foam constructions.
• Layered massage feel: Two massage foam layers (2.5 cm and 2.5 cm at different densities) plus super-soft foams create an immediate plush response while the pocket core supplies the lift and durability.
• Reduced-glue construction: Non-glue cotton and eco-friendly white felt reduce adhesive use in the comfort panel for a cleaner construction profile.
• Stable, anti-slip base: Keeps the mattress secure on slatted frames or solid bases common in Perth homes.

Care & Maintenance

• Use a mattress protector to guard the 240 g cover from spills, dust and sweat; the simplest strategy to extend life.
• Spot clean only: Blot spills immediately with a clean, barely damp cloth and mild detergent; avoid soaking foam layers. Allow thoroughly to air dry before remaking the bed.
• Vacuum regularly with a soft upholstery nozzle to remove dust and surface particles.
• Rotate occasionally (head-to-foot every 3–6 months) to even out wear across the comfort layers.
• Ventilation matters in Perth: Ensure slatted bed bases or good under-bed airflow and keep indoor humidity in check to prevent damp and mould; recommended indoor humidity for prevention is roughly 40–60%.
