Keep it clean. To improve the hygiene of bedding, dry the mattress, bed mattress, regularly clean the mattress with a vacuum cleaner, keep it clean. If the mattress is stained, use a toilet paper or cloth to absorb moisture. Do not wash with water or detergent. It is best to have the habit of using sheets or cleaning pads, while avoiding lying on the bed after bathing or sweating, and not using appliances or smoking in bed. 3. Don't sit on the edge of the bed often. Because the four corners of the mattress are the most vulnerable, sitting on the edge of the bed for a long time, it is easy to damage the edge spring. 4. Don't jump on the bed, lest the single point is too strong and the spring will be damaged. 5, some mattresses have vent holes at the edge of the enclosure. Do not stretch the sheets or mattresses when using them, so as to avoid blocking the vents, resulting in the air in the mattress being unable to circulate and breeding germs.
