Latex mattress can cause skin irritation in people with latex allergies, including painful rashes. Because latex mattresses do not ventilate well, they can accumulate moisture on their underside in humid rooms with poor circulation. Excess moisture can lead to mildew growth, according to "The Rise of the Superconductors."
A cotton pillow top combined with a dense mattress cover can reduce contact with the mattress for someone with mild sensitivity to latex, according to "Dermatology." To prevent moisture build up, place a dehumidifier in the room. Do not place the mattress flat against a surface like the floor or wood so air can move around its underside.
Latex mattresses, especially all natural organic types, can cost twice as much as traditional mattresses, according to "Squeaky Green," a guide to environmentally friendly living. For a person who experiences severe reactions when exposed to latex, changing to a traditional mattress is safest to avoid exposure when changing bed linens or other household tasks.
