The Eight-Year Mattress Itch

New homeowners are constantly being bombarded with advice from parents, neighbours, friends, and family. Among the wisdoms are the everyday tasks of how to take red wine out of carpet, the best way to remove baked-on cheese from a pan, and how to clean hardwood floors. Then there is the advice about maintenance and general upkeep. These tidbits include when to replace a furnace, how to inspect a roof, and what to do about standing water in the basement.

Advice About the Mattress

Oftentimes, along the way someone will mention that a mattress needs to be replaced every eight years. At this point, a homeowner will often scoff and decide that this notion is a scam, as there does not seem to be a discernible point to replacing a perfectly good piece of household furniture so frequently. Unlike the furnace, septic system, or roof, there are no drastic consequences to not replacing a mattress. However, a look into why mattresses are replaced according to this timeframe will have you jumping online to look at the information on

Why You Replace Your Mattress

If you have ever replaced a mattress, you already know that it weighs significantly more on the way out the door than on the way in. If you have never had the experience of buying a new mattress, go lift one at the nearest store and then compare it to your old one at home. The difference is immediately noticeable.

For a long time, homeowners did not know why a mattress nearly doubled in weight over the years. As it turns out, the answer was obvious. Despite the protection of mattress covers and sheets, dead skin, moisture, dust, and other debris were seeping into the mattress. These bits and bobs were essentially accumulating within the mattress and slowly building up over time. While this does not make a difference in the hygiene or weight of your mattress on a day-to-day basis, over the recommended eight-year period, it changes the consistency, durability, and firmness of your mattress.

Sleeping for an Upgrade

Even if you doubt the information on the accumulation of dead skin and dust in your mattress, there are other reasons to regularly replace it as well, the most important one being that an older mattress does not support your weight like a new mattress does. In addition to the consistency and firmness changing due to debris, the structural integrity of your mattress also decays over time.

This change in support affects sleeping habits and general comfort. For many people, this leads to more restless nights and fewer hours of sleep. After years on the same mattress, people are waking up less rested and not as prepared for the day ahead. The amount of sleep you get and the quality of that sleep affects cognitive abilities, stress levels, and emotions.

For others, the side effects of bad sleep are even more serious. People are constantly developing pain or injuries from sleeping on an old, worn mattress. Sometimes the effect is pain in the lower back or neck, and other times it can lead to aches and pains in the hips or legs. For these individuals, buying a new, comfortable mattress is non-negotiable.
