When does a mattress need replacing?

• After 7 to 15 years of use, although many people use their mattresses for many more years.
• Experts indicate that two adults sleeping nightly on a queen mattress will notice the padding, not the coils, breaking down after a period of 4 to 6 years. While the mattress will still be comfortable, it will no longer feel the way it did when first purchased.
• When laying a hand on the mattress with about 3 pounds of pressure and sliding it over the mattress lumps can be felt.
• When the user regularly wakes up feeling tired, stiff, achy and sore.
• When inner coils start springing out of the mattress.
• When the mattress shows very visible deformities.
• When the mattress looks old, frayed or worn.
• When the mattress is normally sagged, has lost its flat shape and there is an impression of the user sleeping on it, especially, a noticeable sag in the middle of it.
• When the box spring creaks and squeaks.
• When the user has difficulty finding a comfortable position to sleep in.
• A thing to consider is that a regular person exudes about 0.5 liters of liquid a night, although probably the majority of it evaporates. Mattresses normally absorb moisture from the body, so after years of use it is probably saturated with the salts of the perspiration.
