Care & Maintenance

1. Vacuum the surface regularly using a soft upholstery attachment.
2. Spot-clean spills promptly with a mild soap and barely damp cloth (avoid saturating the foam).
3. Use a quality mattress protector to prevent stains and extend life.
4. Allow any cleaned spots to dry thoroughly to avoid moisture buildup.
5. Memory foam benefits from minimal moisture and good airflow, so avoid steam cleaning or heavy soaking.
6. Regularly launder sheets and rotate the mattress head-to-foot (if recommended by the product tag) to even wear.

Sustainability

The WSM-111 classic mattress prioritises longevity and low waste by using high-density foams that retain support and shape over years, plus a durable jacquard cover designed for easy care. Together these choices reduce the need for early replacement and help lower long-term environmental impact.
