Allergies stand between many people and a great night's sleep. Not only this but sleeping on the wrong kind of mattress can mean waking up tired and the continuation of symptoms through out the day. These hypo-allergenic mattresses can be a breath of fresh air and improve not just your sleep but your quality of life. Designed to prevent reactions to allergies, they are tightly sealed to prevent dead skin and body oil getting into the mattress and providing a breeding ground for dust mites which cause allergic reactions.
