For a soft mattress, it is not easy to maintain the highest comfort, but also to perform well in support.

Though select a suitable soft mattress is not easy, we can still follow some clues. Here we will review the soft mattresses from different manufactures and introduce the most important factors for choosing the best soft mattress. If you decide to have a soft mattress, this article can be your perfect reference. We did many studies to make it easier for choosing a soft mattress.

Let’s dive in.

Soft vs. Firm Mattress

Mattresses are usually made of multiple layers that work together to provide a soft or firm feeling. In the mattress industry, we use a firmness number to indicate how the surface of the mattress feels. The firmness is affected greatly by the covering and comfort layer (or the top layer) of the mattress. We measure it by a scale of 1 to 10. The lower the numerical value, the softer the mattress should feel. The higher the numerical value, the firmer the mattress will feel. 1 means softest and 10 means the hardest. Most mattresses sold in the market have a number between 3 (“soft”) and 8 (“hard”). Though the firmness number is corresponding to the subjective feeling of the mattress surface, it is still important to experience it when you choose the mattress.

Generally, soft mattresses are popular in side sleepers because they improve the alignment and decompression of the spine. Also, people in lightweight love the soft mattresses very much, because they provide more consistency to the body shape than firmness models. Though there are lots of benefits, soft mattresses have some obvious drawbacks. One of the most mentioned problems is that you may tend to sleep hot in a soft mattress for the poor heat dissipation ability. If you are heavy, you can feel “sinking” when sleeping in a soft mattress. Also, the soft mattress has a shorter lifespan than the firmness mattress.

Here are general guidelines for mattress softness and firmness.

1 Extremely softA mattress that lets you feel you are “sinking in” the bed.
2-3SoftYou can feel the “sinking in”, but not so clear and remarkable.
4-6MediumA mattress that lets you feel less “sinking” but still soft.
7-9FirmA harder mattress that will not “sink in” and feels less soft.
10Extremely firmThe hardest mattress that does not let you “sink in”, and is not soft.

Is a soft mattress suitable for you?

Good sleep is the result of many factors, including the mattress firmness, sleep posture, body height/weight, age, health status and so on. The feeling of softness is different for every single person. A mattress that is very soft for you may feel firm for others. 

Meanwhile, your weight also affects how soft or strong the mattress feels. In some cases, you may feel soft in the showroom of the mattress store, but feel firm at home. That is why most mattress manufactures provide sleep trials for users, which is very important for you to select a long-term satisfied mattress. 

Though the soft feeling is subjective and varies for everybody, there are still some signs and indications that show you whether you need a softer mattress. 

If you wake up and feel pain at pressure points such as shoulders and hips, you may need a softer mattress (your current mattress may be too hard).

If you sleep cooler, you may need a softer mattress to help you keep the warm temperature during sleep.

If you are in lightweight and you want to have a feel of hug, a softer mattress is suitable for you.

If you are disrupted by your sleep partner, a high-quality soft mattress with the ability of motion isolation can perfectly solve your trouble.

Who is suitable for the soft mattress?

  • Side sleepers
  • People who tend to sleep cool
  • People in light or average weight
  • People who are sleep lightly and easily disrupted by other things
  • People who are suffering sleep apnea

Soft mattresses are more popular in side sleeper group. According to the study, a soft mattress can cushion your neck, shoulders and hips better than a firm mattress. The comfortable feeling makes side sleepers love the soft mattress very much. However, if the mattress is too plush, you may sag in and lose your spine position.

The colder sleepers are those who get colder at night, not those who wake up sweating and kicking the quilt. Thyroid insufficiency or other diseases may make you feel cold at night, or you may just be one of those people who feel colder than others. Soft mattresses conform to your body shape, allow you to cradle and use your body’s heat to keep warm. It looks a better choice for colder sleepers.

People with lighter weights are also suitable for soft mattresses. The heavier you are, the more likely you are to fall into the comfort layer of the mattress. If you weigh less, the stronger the mattress, the more uncomfortable it will be, so if your BMI is low, you may want a softer mattress.

Older people would like to enjoy softer mattresses. Because older people tend to run colder, a thicker and softer mattress allows you to sink in and enjoy the benefits of insulation. Thicker comfort layers can well protect body joints that become more fragile and weak with age. If you are sensitive and sleep light (cannot full into deep sleep easily), a soft mattress can make you sleep better and wake up feeling no pain.

You may be suffering the objective sleep apnea, which is not a sleep problem, but really affect your sleep quality. According to the study, side posture helps treat objective sleep apnea. A soft mattress can be a better option for side sleeping.

Who is NOT suitable for the soft mattress?

  • Stomach and Back Sleepers
  • People in heavyweight
  • People who tend to sleep hot
  • People who have backache
  • Young Children
  • Arthritis patients

If you sleep on your stomach or your back, a soft mattress may cause you to sink too deep, depriving your spine of its natural “S” curve. If your sleeping posture is incorrect, you wake up with back pain or other body aches. For those who sleep face up or face down, a firmer mattress is better.

Heavier people should not sleep in soft mattresses. The heavier you are, the more likely you are to fall into the comfort layer of the mattress. If you sink into the mattress too much, you may find it difficult to change your posture, which increases your body discomfort. You will find that you are trapped into an excessive hammock effect and your spine loses the alignment for uneven support.

If you are a person who tends to sleep hot, a firm mattress is better for you. Commonly, the less you sink in, the cooler your body is. Related research suggests that when you are in a deep sleep, your body temperature should drop a little. If you run hotter while sleeping, your sleep will be less stable. And a firm mattress may be better for keeping the proper temperature for you.

Backache patients were used to be advised firm mattresses. This theory has been overturned by extensive research, which shows that a medium-firmness mattress is more suitable for the treatment of back pain. Soft mattresses may not work well, because in some cases they can not provide enough and even support for a painful spine.

Body, toddler, and young children are not suitable for the soft mattress either. Soft mattresses may reduce their sleep quality, and even affect their spine alignment. At the same time, children’s sleep patterns vary with age, a firm mattress is much better to provide consistency to the body.

As we have mentioned, the older person has fragile and weak joints. A soft mattress can help to protect them well. But on the other side, a too soft mattress is not good for older people. A mattress with a stronger support layer and a softer upper comfortable surface is ideal for older persons.

Benefits of Soft Mattresses

You can enjoy and take advantage of a soft mattress if you are suitable for it. 

1. More comfortable

This is the biggest benefit of soft mattresses. The soft and comfortable layers will cradle your body, allow you to enjoy the “sinking” feeling that many people like. A strong mattress does not have such a feeling. 

2. Sleep Warm

According to sleep research, sleeping too hot will wake you up. However, sleeping too cold can also wake you up and disrupt your sleep cycle. Overlaying blankets can help those who run colder, but a softer sleeping surface allows greater “sinking” and will use your body temperature insulation to make you warmer at night, if that is your preference.

3. Comfortable to sit up

If you love to sit in bed reading, watching TV or surfing the Internet on a tablet or laptop, a soft mattress will let you sink in and give comfortable support for your hips and thighs. 

4. Motion isolation

Soft mattresses can give improved motion isolation. If your partner often moves at night, a firm mattress becomes a problem because you may feel clear about his/her every move. A soft mattress that is good at motion isolation can protect you from disrupting by motion transfer.

5. Pain relief

If you wake up with pain in your hips, shoulders or neck, a soft mattress may be the answer. The thicker comfort layer eliminates the pressure area and evenly transfers them to the mattress surface. A soft mattress that conforms to your body but prevents it sinking excessively is helpful for relieving the pain when you wake up.

Tips for Buying a Soft Mattress

Now you have decided to select a suitable soft mattress. Here we give you some tips for buying a soft mattress and how to maintain it in the next few years.

1. Using sleep trials

As we have mentioned, most mattress manufacturers provide sleep trials for customers. Since the soft feeling is subjective, we strongly recommend you to fully use the sleep trails. It gives you a chance to deeply experience the mattress. If it is not satisfied with you, you can return the full or partial refund of the mattress before the end of the trail. Or you can replace your current mattress with a different firmness model. The detail sleep trails clause depends on every single manufacture.

2. Understanding warranty coverage

Usually, your mattress has several years’ warranty, such as 10 years or even more. You want to check carefully for your warranty coverage, especial the cases that are out of the warranty range. Surface sinking is a common problem for soft mattresses after using a period. In most cases, mattress manufacturers list excessive sagging and indentations within the product warranty coverage. If your soft mattress begins to sink prematurely, you can repair or replace it at the lowest cost. However, if you want to change the mattress because of your firm preference, it is usually not covered by your warranty. 

3. Firmness can affect your pillow choices

Sleepers tend to sink deeper into soft mattresses, so it is not necessary to provide much cushioning for the head. Too much cushioning can cause pain and stress in the neck and shoulders. For this reason, lower and thinner pillows are usually recommended for softer mattresses, rather than higher and thicker pillows.
