How do firm and soft mattresses differ?
Firm and soft mattresses offer different sleeping sensations. Some people experience back pain on a firm bed, while others feel uncomfortable on a soft bed. Therefore, before changing your mattress, you should consider whether you prefer a soft or firm feel to make the right choice. Here's how firm and soft mattresses provide different sensations:
- Firm Mattress: A firm mattress is designed to support the body's contours and distribute the sleeper's weight well. This provides a stable feeling during sleep, preventing the body from sinking into the mattress, allowing for uninterrupted sleep without aches or back pain.
- Soft Mattress: Soft mattresses are designed to offer a plush and comfortable feel upon lying down. When you lie on a soft mattress, your body will sink slightly into the material, helping you to relax and fall asleep quickly.
Does sleeping on a firm mattress really cause back pain?
Some people believe that sleeping on a firm mattress can help with back pain. However, sleeping on a mattress that is too firm can actually worsen back pain. This is because during sleep, the body's weight is distributed onto the bed, and certain parts of the body bear more pressure than others, which can affect the spine and lead to back pain.
Who are firm mattresses suitable for?
Many people may not know whether they are suited for a firm or soft mattress. Let's look at who firm mattresses are suitable for to help you choose the right mattress:
- Those who sleep on their back or stomach, as it better supports spinal alignment than a soft mattress.
- Elderly individuals, as the mattress provides good body support, especially for the back, reducing the incidence of back pain.
- Individuals with back pain, as a moderately firm mattress helps align the body properly, thereby alleviating pain.
How to prevent back pain and wake up feeling refreshed every morning

Everyone wants to wake up feeling refreshed. But if you wake up with back pain, it might be due to an improper sleeping posture, which can stem from various factors, including your bedding or personal habits. Here, we'll recommend ways to alleviate back pain and feel comfortable after waking up:
1. Improve blood circulation
When the body's systems, including blood circulation, function efficiently, various body parts such as muscles and nerves can recover quickly, thus alleviating existing back pain. Blood circulation can be improved in several ways, such as taking a warm bath, using thick blankets, or wearing socks to prevent the body from getting too cold during sleep, among others.
2. Choose an appropriate pillow height
Even though a moderately firm mattress can help reduce back pain, pillow height also impacts aches and pains. Sleeping on a pillow that is too high or too low can cause the spine to curve and the neck to bend. Therefore, you should choose a pillow with an appropriate height that suits your body's contours, allowing your spine to remain straight and alleviating back pain.
3. Adjust your sleeping position correctly
Adjusting your sleeping position correctly can help reduce back pain. However, an uncomfortable sleeping position can also lead to discomfort. Here, we will recommend ways to adjust each sleeping position to suit your preference:
- Back sleeping position Lie on your back with your head supported by an appropriate pillow. Place a small bolster under both knees to reduce spinal arching, which can improve existing back pain.
- Side sleeping position Lie on your preferred side with your head on an appropriate pillow. Slightly bend both knees and place a bolster between your bent legs to align your spine, which can alleviate tightness in your back.
- Stomach sleeping position In reality, sleeping on your stomach should be avoided as it causes the spine to arch and can affect breathing during sleep. However, if you must sleep on your stomach, place pillows under your neck, upper chest, and hips, and turn your face to your preferred side to reduce back pain.
4. Choose a mattress that suits you
A mattress can enhance sleep quality and help alleviate back pain. However, what constitutes a "good" mattress depends on each person's sleeping preferences. Some find a firm mattress just right, neither too firm nor too soft, while others experience back pain on a firm mattress and may need to seek a softer option until they find one that suits them.
Even if you find a suitable mattress, mattresses have a lifespan. If you notice your mattress sagging unusually or losing its shape, replace it to reduce the risk of back pain.
How to choose a mattress to avoid back pain
Choosing a bed that suits your body shape can help alleviate and prevent back pain. Let's look at how to choose a mattress to avoid back pain and body aches:
- Material: The materials used to manufacture beds have different properties, resulting in different sensations when lying on the bed. For example:
-
-
- Spring mattresses contain various types of springs inside, such as pocket spring mattresses, where springs are individually packed, excelling at localized support, easy turning, and reducing motion transfer to a sleeping partner. Or Bonnell spring mattresses, which connect coils into a single unit, preventing the body from sinking into the mattress.
- Latex mattresses are made from natural or synthetic latex, offering high durability and resistance to sagging, yet not being overly firm.
-
-
Size: Mattress size has a slight impact on back pain. If you choose a bed that is too small, such as a 3.5 ft mattress, it can make it difficult to turn over comfortably, leading to sleeping in the same position all night, resulting in increased body aches upon waking, and potentially even falling out of bed and getting injured.
So, what size should a bed be? For those who sleep alone or have a small build, a 3.5 ft mattress is recommended as it allows for comfortable turning. However, if you have a larger build, you might consider upgrading to a 5 ft mattress to provide more space for movement while sleeping.
Or if you want ample sleeping space with room for two people or bedding, a 6 ft mattress is recommended, allowing both individuals to turn over freely and comfortably.
-
Firmness Level: The firmness of a mattress affects back pain. If the mattress is too firm, the pressure from body weight won't be distributed evenly, causing pain in certain body parts. However, if the mattress is too soft, the body will sink into it, making movement difficult.
Therefore, you should choose a mattress with a moderate level of firmness that can support your body weight when you lie down. The mattress should also be able to conform to the curves and contours of your body to maintain a correct sleeping posture.
