How Can An Old Mattress Affect Your Sleep

June 06, 2023

Mattresses in India, or anywhere around the world, typically last 8-10 years, or longer if of high quality. During that time, it conforms to your body's curves and demands, allowing you to sleep peacefully. However, over time, excessive weight and pressure, friction, moisture absorption, and the accumulation of dust, grime, and microorganisms can damage the mattresses. Causing it to lose its initial shape, resilience, and structural integrity, causing discomfort. And then your bed, rather than giving relaxation and pleasant sleeping, becomes the source of sleepless nights, backache, and disrupted sleep. As a result, it is critical to replace your mattress when it becomes old and worn. Otherwise, it can disrupt your sleep and health in multiple ways.

Doesn’t Provide Necessary Support

Mattresses are designed to provide not just comfort but also proper support to maintain body posture, spine alignment, and pain reduction. The mattress's core layer provides substantial support to prevent sinking, while the comfort layers provide the essential sinking feel and body contouring. However, as time passes, the mattress's material and construction lose their quality, stability, and structure.

Doesn’t Provide Necessary Support

The innersprings break and get damaged, the foams and other components sag, wear and tear off, and the necessary support is no longer provided. When you lie on such a bed, your body does not receive adequate support and sinks into the bed, resulting in poor spinal alignment and worsening or triggering back problems.

Increases Allergic Reactions Due To Lack of Hygiene

It is quite common for mattresses to accumulate dust, dirt, pollen and pet dander. Additionally, dead skin cells and body fluids from sweating or drooling can accumulate in the mattress, providing a food source for dust mites to thrive. These microscopic microbes can induce allergic symptoms such as sneezing, runny nose, itchy eyes, and even asthma attacks.

Lack of Hygiene

Moreover, it can also attract other allergens like mould and mildew, especially if it has been exposed to moisture. Mould spores can trigger respiratory problems and allergic reactions, and they can be difficult to eliminate.

Regular cleaning and maintenance of your mattress can help reduce the number of allergens it harbours. However, if you're experiencing allergy symptoms that you suspect may be related to your mattress, then it is best to replace it and buy a new mattress with hypoallergenic qualities to ensure a healthier sleeping environment.

Disrupt Slumber Due To Increased Motion Transfer

Some mattress types like memory foam or pocket spring mattresses have inbuilt motion transfer prevention quality. Which provides an undisturbed sleep surface for you and your partner. However, with time and constant use and decreasing agility, this ability may decline and you might feel the motion on every part of the bed causing sleep disruption. When this happens, the mattress may not effectively absorb or distribute the movement caused by one person turning or shifting while sleeping. As a result, the motion can transfer more easily across the surface of the bed, disturbing the sleep of a partner sharing the bed.

Increased Motion Transfer

Increased motion transfer can lead to disturbances, such as waking up when your partner moves or feeling the effects of their movements throughout the night. It can also cause discomfort and difficulty in finding a comfortable position, leading to fragmented sleep

If you're experiencing disrupted sleep due to increased motion transfer, it might be worth considering replacing your old mattress. A new mattress with good motion isolation properties, such as those designed with memory foam or pocketed coil systems, can minimize the transfer of motion and provide a more restful sleep experience.

Causes Poor Temperature Regulation

An old, deflated, and worn-off mattress gradually compresses within itself, removing the air pockets or space essential for optimal air circulation. Because there is no air circulation, the mattress becomes hot, dusty, and less breathable. And it is no longer as effective as it once was at dissipating heat and moisture, causing discomfort and disrupting sleep. Over time, the mattress’s materials, such as foam or padding, can break down and become less breathable. This can result in reduced airflow and ventilation, trapping heat and causing the bed to retain warmth. As a result, you may feel excessively hot and uncomfortable during sleep.

If your mattress has poor temperature control, it is best to purchase a new one with features designed to address this issue. Look for mattresses with cooling technology or materials known for their temperature-regulating capabilities, such as pocket springs or gel-infused memory foam. Furthermore, using breathable mattress protectors or cooling mattress toppers can aid in temperature management and enhance the sleep experience.

Doesn’t Offer Proper Support

An old mattress, regardless of its form or manufacture, loses its support structure as the coil system and support layers break and deteriorate. This can lead to uneven weight distribution, causing certain areas of your body to sink too deeply or lack the necessary support. This makes the mattress uncomfortable to sleep on and makes it more difficult to establish a comfortable sleeping posture. This causes tossing and turning and impairs your sleep quality.

If you have chronic back pain, spine-related issues, or poor posture, an outdated mattress might exacerbate the situation. A firm support is required in such a case, which an old and worn mattress can't supply. So, if you begin to feel uncomfortable and unable to fall asleep in your bed, or if you notice bulging on your bed, it is time to replace your mattress, ideally with an orthopaedic mattress.

Doesn’t Offer Adequate Cushioning

A mattress' padding and cushioning layers are intended to provide a soft and comfortable sleeping surface. These layers, however, can degrade, compress, or acquire lumps and indentations as they age. The mattress may feel uneven, saggy, or lumpy, making finding a comfortable sleeping position difficult.

Doesn’t Offer Adequate Cushioning

If you sleep in the same position every night, it may create an impression on the bed that later becomes deep. On such mattresses sleeping and getting comfortable become difficult and you may also suffer to switch positions or roll on the bed.

Cause Aches And Pressure Points

One of the biggest disadvantages of worn-out is that it does not provide the necessary support, firmness, cushioning, and comfort, which can result in severe and chronic back discomfort. It disrupts your spine's natural alignment and fails to relieve pressure points, such as hips, shoulders, and joints.

Cause Aches And Pressure Points

Without sufficient cushioning and support, these pressure points can experience increased stress, leading to discomfort, aches, and pains. The aches and pains worsen with time, producing major health problems.


Old mattresses can have a significant impact on the quality of your slumber. Over time, it loses its firmness, support, and shape, leading to uncomfortable pressure points and poor spinal alignment. This can result in aches, pains, and stiffness, as well as restlessness throughout the night. Additionally, the accumulation of dust mites, allergens, and other irritants can exacerbate respiratory issues and allergies.

To ensure that you're getting the best possible sleep, it's essential to invest in a high-quality, supportive mattress and replace it every eight to ten years. If you find yourself waking up with discomfort, experiencing poor sleep, or noticing visible signs of wear and tear on your mattress, it may be time to invest in a new one to ensure a comfortable and supportive bed surface. By doing so, you can improve your overall health and well-being and enjoy a more restful, rejuvenating sleep.
