Key points

  • Ventilation first. Open windows when it is dry, use fans and consider a dehumidifier in persistently damp rooms.
  • Use the right base. A slatted or ventilated base lets air circulate.
  • Protectors and sheets. A breathable protector and cotton sheets keep moisture away from the mattress.
  • Clean and air. Vacuum gently, spot-clean spills with mild soap and let the mattress dry fully.
  • Watch for mould. Musty smell or dark spots mean moisture; dry and ventilate immediately.

Ventilation first

Open windows when it is dry, use fans and consider a dehumidifier in persistently damp rooms.

Use the right base

A slatted or ventilated base lets air circulate. Solid bases trap moisture underneath.

Protectors and sheets

A breathable protector and cotton sheets keep moisture away from the mattress.

Clean and air

Vacuum gently, spot-clean spills with mild soap and let the mattress dry fully. Air it standing against a wall when conditions allow.

Brief airing in indirect sun can help, but check care instructions because some materials dislike strong sunlight.
