The most important factor when selecting a mattress is choosing the right firmness level. The best firmness level depends on your personal preferences and different factors including your sleeping position, weight or height. Measuring the firmness level is done on a scale from 1 to 10, with 1 as the least firm level and 10 as the firmest level. Most mattresses that are made today have their firmness level in a range from 3 (or ‘Soft’) to 8 (or ‘Extra Firm’).

For people who are lighter (less than 130 pounds) and who are average weight (130 to 230 pounds) a suitable choice would be a softer mattress, because firmer mattresses don’t have good conforming, and can ultimately cause discomfort or even pain in the lower back, neck, shoulders or other areas that are also sensitive.   

Side sleepers also prefer to pick softer mattresses, because this position of sleeping needs good cushioning in the shoulders and hips in order to properly align the spine, pelvis, and neck. Improper alignment causes aches and pains in these areas.

People who are heavyweight (more than 230 pounds) most of the time don’t feel very comfortable on soft models because they have a tendency to sink too deep in the bed. With too much sinking, the bed’s support is compromised, and as a result, heavier sleepers can experience a lot of discomfort.

To find out more about factors that you need to consider if you’re choosing a softer mattress, read our guidelines in the article and our top picks for the best soft mattress you can find on the market. Our top 6 choices of the best soft mattresses are based on verified buyer and owner reviews, and of course, on our intensive product research.

Soft Mattress Buyer’s Guide

The firmness level of a mattress shows how the bed ’s surface feels on your body. The comfort layer and the cover are the ones who are responsible for the overall firmness of the bed. Firmness is measured with a 1-10 scale, with 1 being the least firm and 10 the firmest. However, most of the mattresses sold on the market today are between a 3 (‘Soft’) and an 8 (‘Firm’).

In this part of the article, we will talk about soft mattresses that have a firmness level of 4 (‘Medium Soft’) and lower. Soft mattress models are the best for people who sleep on the side because it improves the alignment of the spine and pressure points. It is also good for lighter people because soft mattresses give them good conforming, which they can’t get with firmer mattresses. But, soft mattresses do have some downsides. They have a lot more off-gassing odor, high body heat retention, and most importantly, a shorter lifespan.

 

Who Sleeps Best on Soft Mattresses?

You might be wondering what can a soft mattress offer you and who would sleep on one. In this part, we will address different physiological factors, like the weight of a person and how he or she sleeps, which are usually good indications that the sleeper might like a softer bed. Of course, every person is different, and the information that we will give applies to most mattress buyers, but it certainly does not apply to all buyers and owners. It is important to test mattresses with different firmness levels to find out what you prefer before buying the final product.

The first factor we will consider is weight. For the purposes of this article, we will treat the average weight to be between 130 and 230 pounds, and therefore, above-average will be anything over 230 pounds and below average will be anything less than 130 pounds. The weight of a person is one physical factor that is directly linked to the firmness of a mattress. People with above-average prefer a firmer mattress, while people below average weight prefer a softer mattress. The reason behind this preference is the pressure relief and conforming of a mattress. Models that are softer have a tendency to sink deeper when in contact with a body, and firmer models will only sink if the sleeper has enough weight. Because of these people who have low or average weight won’t sink easily, and therefore, feel comfortable in a softer mattress. They can experience the effects that a soft mattress can give. A soft bed will relieve pressure and give good conforming to the body, and especially the spine. However, people who have more weight can sink too deep into a mattress model that is soft, and experience more pain and pressure. It is because of this that they feel more comfortable on firmer mattresses.

The table underneath will give you the most popular firmness ratings for each of the three weight groups we talked about.

Weight Group The Usual Mattress Firmness Preference
Average (130 to 230 Pounds) 5 (Medium) to 6 (Medium Firm)
Above-average (More than 230 Pounds) 7 (Firm) and Higher
Below-average (Less than 130 Pounds) 4 (Medium Soft) and Lower

 

Another factor that influences firmness preferences is the position a person sleeps in, because softer mattresses conform more closely, and ultimately improve the alignment of your spine. Sleeping on the back is best for spine alignment, and back sleepers might not need a mattress for spine alignment. However, people who sleep on the side create a curvature in the spine that is not natural, and because of that require a product with enhanced support in the lower back, hips, neck, and shoulders, to help reduce pressure and pain. That’s why people who sleep on the side generally prefer mattresses with a Soft or Medium firmness. As for those who sleep on their stomachs, it’s common that the majority of them don’t like sleeping on soft beds. Stomach sleepers often find soft mattresses uncomfortable because they sink too profoundly, which forces them to turn their heads to not lay face-down on the bed and they experience increased pain and pressure in this kind of position. This is especially problematic for heavier stomach sleepers, as a high percentage of their weight is usually concentrated in the stomach area. However, people who have below-average weight might feel comfortable on a Medium Soft mattress because they give very good conforming with very little sinking.

The table below gives you information on the preferred firmness levels for people with different weight and sleep position.  

Weight Group Best Firmness for Side Sleepers Best Firmness for Back Sleepers Best Firmness for Stomach Sleepers
Average 4 (Medium Soft) to 6 (Medium Firm) 5 (Medium) to 7 or 8 (Firm) 6 (Medium Firm) to 7 or 8 (Firm)
Heavy 5 (Medium) to 6 (Medium Firm) 6 (Medium Firm) to 7 or 8 (Firm) 6 (Medium Firm) to 7 or 8 (Firm)
Light 3 (Soft) to 5 (Medium 4 (Medium Soft) to 6 (Medium Firm) 4 (Medium Soft) to 6 (Medium Firm)

 

General Qualities that Soft Mattresses Have

After reviewing the factors that a soft mattress has, let’s go over some of the performance and construction factors that many mattresses of 4 or below firmness level have.

  • Shorter Lifespan: Because softer mattresses usually have much more cushioning layers in the comfort system, these layers tend to sag or form indentations. After some time, these can make sleepers encounter increased pain and pressure.
  • Higher Price-point: Softer bed usually have a lot of latex or memory foam layers in their comfort systems, which often increases the price of a mattress. Firmer beds have fewer layers in their comfort systems and are the cheapest options.
  • Thickness: As a result of a higher number of comfort layers, softer mattresses have a tendency to be much thicker than firmer models.
  • Conforming and Pressure Relief: As we’ve mentioned before, softer mattresses usually give great conforming and pressure relief for people with below-average and average weight, due to the fact that they sink deeply, but not too deep. People with above-average weight can sink too much and that’s why they usually pick a Medium to Firm mattresses.
  • Harder to Move: Softer models that have more layers in their comfort system are often heavier, and because of this, they are harder to move. This factor also depends on the type of a mattress. Some models, like memory foam ones, are usually lighter than other soft models like innersprings, because of the weight and density of mattress components.
  • Sleeping Hot: There are two reasons to why sleeping is somewhat uncomfortable on a softer mattress. We have already mentioned the first reason – sinking deeper than in firmer mattresses. This is uncomfortable because it can restrict airflow on the surface and create a body heat trap. The second reason is that models that have multiple foam and memory foam layers are much softer and warmer than firmer models with just one or maybe two foam layers. This happens as a result of body-heat-retaining properties of the foam.
  • Lack of Responsiveness: Responsiveness of a mattress refers to how quickly the product responds to the body of a person. The lowest responsiveness is with softer mattresses, because of the close conforming. As a result, these models aren’t responsive enough for sex like the Medium/Medium Firm models, which have the perfect balance of responsiveness and softness.
  • Odor: Some products can emit smells, most commonly known as off-gassing, when they are unpacked. The majority of these odors disappear after a day or two, but some models can have more unpleasant smell that lasts longer. The models that tend to be the softest, with memory foam and polyfoam, are the ones that are often long-lasting and contain unpleasant smells.

 

Tips for Buying a Soft Mattress

After looking at the characteristics and factors to consider for having a soft mattress, we will now focus on buying this kind of product. If you have decided that a softer mattress is what you need, take a look at some tips or buying the right model, and what comes with it.

  1. Sleep Trials: The majority of manufacturers actually give permission to buyers to take part in sleep trials. After a purchase has been made, the buyer can test out the mattress for determined period of time (usually 90 to 120 days). If buyers decide that they do not want the mattress and wish to return it before the trial ends, they can do it and get either a full or a partial refund. In some cases, buyers can exchange their current product for a different model.
  2. Warranty Coverage: Because it is common, manufacturers have a product warranty that covers excessive sagging and indentations to a certain depth (usually 1″ to 1 1/2″, but in some cases even lower). When softer mattress starts to sag or indent too soon, you can have it repaired or you can replace it at very minimal cost.
  3. Dual Firmness Mattresses: Like with most things, couples tend to disagree about the firmness rating of a mattress. Many couples have sleep problems which makes choosing the right mattress for both sides difficult. For this reason, some manufacturers have made mattresses that have different firmness setting on each side, to fulfill the request of couples who can’t agree on a firmness level. These dual-firmness beds are very comfortable and practical, but can be relatively pricey.
  4. Flippable Mattresses: Aside from the dual-firmness models, a limited number of manufacturers have flippable mattresses. This sort of flippable mattress design has two comforts layers, but each of them has a different firmness rating that share a support core. In order to adjust or change the firmness of the mattress, you just need to flip the mattress over.
  5. Firmness Influences Your Pillow Selection: The most common problem with softer beds is sinking too deeply, and because of this, these models do not need much cushioning for their head. Putting excessive padding leads to creating pressure and pain in the neck and shoulders. Because of this, thinner pillows are more recommended for softer mattresses.

 

Conclusion

Ultimately, a soft sleeping surface can be a good option for you if you have average or below-average weight. A soft mattress is also good for people who sleep on the side.
