A hypoallergenic mattress is designed to prevent allergic reactions. Most hospitals and medical care facilities use mattresses that are wrapped in plastic or vinyl to ensure patients stay healthy. The mattress is tightly sealed to prevent dead skin cells and body oils from permeating into the material to prevent dust mites from infesting the mattress. Dust mites and other microscopic organisms cause allergic reactions, so it is important that a mattress is made of materials that will not aggravate allergies. A mattress can be wrapped with a mattress wrap or plastic. Another alternative is to purchase a mattress that is made of hypoallergenic materials so as not to induce allergies.
People who suffer from allergies should refrain from sleeping on mattresses made of animal products such as hair, wool, or feathers. Animal-based materials can cause flare-ups for allergy sufferers. Most hypoallergenic beds are made with natural materials such as cotton or filled with artificial materials such as polymers which resist allergy-causing organisms.
