Some people just like a softer mattress, whether it’s because they sleep on their side or because they just have a personal preference.  If you want a soft mattress, just because you think a mattress has the right softness doesn’t mean it’s going to be a perfect fit for you.  In this article, I’ll try go through who might be a good fit for a softer mattress and then lay out a few mattresses that could be a good match.  In each case, I’ll talk about what type of person would be the best fit for it and who might want to look elsewhere.

4 Picks For Best Soft Mattress

There are a lot of contenders, but I wanted to keep this list short.  Here are some options that I think could potentially be a good match for you.

Top Picks Compared

I like the Layla because it uses good quality foams and it is flippable, meaning it has two firmness levels in one.  That gives you two chances to get the right firmness level for you.  The soft side of the mattress is definitely softer than average and is a great option for side sleepers.  The memory foam really just melts away any pressure points that you would otherwise have.

The fact that it is copper-infused is a potential benefit as well, although I would recommend doing your own research to see if you agree with the validity of the claims made there.

What Makes The Layla Stand Out?

  • It is a flippable mattress, meaning it has two firmness levels in one (a soft and firm side).
  • It uses copper-infused memory foam.  The copper infusion can potentially bring you certain health benefits.
  • It is a memory foam mattress that does an excellent job of addressing the issue of sleeping hot.
  • The soft side of the mattress is very soft and is really great at relieving pressure.  Overall, it is one of the most comfortable mattresses I have ever slept on.

Amerisleep AS4

Amerisleep AS4

Amerisleep does not believe that there is one best mattress for everyone.  To back up this belief, they have created a line of 5 memory foam mattresses that all have different firmness levels and are catered to different types of sleepers.  The models go from the AS1, their firmest model, to the AS5, their softest model.  No matter what type of firmness you want in your mattress, you will be able to find a good fit with one of their five models.

The AS4 is their second softest model and it is built specifically for side sleepers.  It has four inches of a very soft memory foam material on the top of the mattress.  That will make it feel very soft for people of pretty much any weight.  I don’t believe that even heavy sleepers will bottom out on this mattress.  It’s a very comfortable mattress that relieves pressure very well and is certainly worth considering if you like memory foam in general.

What Makes The Amerisleep AS4 Stand Out?

  • It uses four inches of a very soft and comfortable memory foam, making it ideal for side sleepers
  • It has a celliant cover, which can potentially provide extra health benefits
  • It is one of the very best memory foam mattresses at addressing the issue of sleeping hot
  • The company uses a manufacturing process that makes the mattress more durable than many of its online competitors

Helix gives you the opportunity to fully customize your mattress based on your weight and other characteristics, as well as personal preferences.  If you want a really soft mattress, for example, you can simply indicate that on your customization quiz and you will receive a soft mattress.

That extra customization is an intriguing option that is unique in the industry.  While some companies have multiple models with different firmnesses, Helix allows you to find something unique to your exact characteristics and preferences.

What Makes Helix Stand Out?

  • The company allows you to customize a mattress based on your answers to a quiz.
  • If you would like a soft mattress, you can simply say that on your customization quiz.  You can get a mattress as soft as you want
  • The mattress is also a good choice for couples because you can customize two sides of the mattress for each sleeping partner

A mattress is opened to show its design.

As a side sleeper, I find the Nolah to be one of my personal favorites.  It uses a proprietary foam in the top layer called AirFoam.  This is a very soft material that does an amazing job of relieving pressure.  The mattress overall is one of softest that I have tested out.  If you are a heavier sleeper, there is a chance that you might bottom out and hit the firmer layers beneath.  That is why the company came out with a thicker 12″ mattress (see that review here).

What Makes The Nolah Stand Out?

  • The proprietary AirFoam does an excellent job of relieving pressure
  • It is one of the softest and most comfortable mattresses I’ve ever slept on
  • For heavier sleepers, they have a thicker, 12″ mattress available
  • The mattress performed very well on our pressure map test (which shows exactly how well a mattress relieves pressure)
  • The mattress is temperature neutral, meaning you won’t sleep hot on it
  • The mattress is more durable than many of its all-foam competitors

Who Should Pick A Soft Mattress

  • Side SleepersSide sleepers often need a softer mattress to relieve the pressure on their shoulders and hips. If you sleep on your side and have a firm mattress, you won’t get as much deep, restful sleep because you will toss and turn frequently throughout the night.
  • Lighter Weight People– Firmness is a subjective measure.  One person might think a mattress is firm, while another person might think the same mattress isn’t that firm.  However, on the whole, people who don’t weigh very much will tend to think a mattress is firmer than those who weigh more.  For this reason, typically lighter weight people will want to get a softer mattress to make up for this fact.
  • People Who Like To Sink Into Their Mattresses Softer mattresses, especially those that are of the memory foam variety, are great if you prefer to sleep “in” your mattress rather than “on” it.
  • Couples– Soft mattresses often have better motion isolation than firmer mattresses. Memory foam is found in many soft mattresses and this does a great job of cutting down on motion transfer in a mattress. If you sleep with a partner, there is less chance you will feel their movements on your side of the bed.

Who Shouldn’t Pick A Soft Mattress

  • Stomach Sleepers– People who sleep primarily on their stomachs usually require an extra level of support. Lying on a softer mattress, their hips may sink too far into the mattress. When this happens, the spine can get out of alignment and cause pain.
  • Some Back Sleepers– While some back sleepers may find the support they need on a softer mattress, others may not get enough support. They may feel their hips sinking in too far and, like stomach sleepers, their spines will get out of alignment.
  • Heavier People– If you are larger, no matter what position you sleep in, a softer mattress may not be the best choice. On your side, you may press through the soft comfort layers of the mattress and “bottom out.” You will then feel the firmer support layers beneath and experience some pressure on your shoulders and hips. Also, when you are on your back and stomach, you may feel your hips sink into the mattress even more.

Will You Sleep Hotter On A Soft Mattress?

While soft mattresses promise comfort, pressure relief, and an enveloping feeling, this can also mean you sleep hot. This can happen for a few reasons and, just because your mattress is soft, doesn’t mean you will overheat.

First, the materials used in your soft mattress are going to play a part in your sleep temperature. Pure memory foam is known for trapping heat. When this happens, it can redirect this warmth back at you.

However, many mattress companies combat these issues by adding air channels and holes to the memory foam layers. Also, they may add other materials like graphite and gel to help with cooling.

A soft mattress can also be a hybrid, and this can help considerably when it comes to sleeping hot. A hybrid with innersprings or coils should have even more airflow.

Second, how far you sink into your mattress may determine how hot you sleep. For instance, if you are really sleeping “in” your mattress, there is less room for air flow and you will trap more heat.

With firmer mattresses, overheating is much less of an issue. However, if you think about these other aspects, you can still sleep cool on your soft mattress.

Other Things To Consider

  • Edge Support– One issue with soft mattresses is edge support. When you sit near the edge, many soft mattresses will completely collapse. This can make it difficult to tie your shoes or sit securely on the bed. Also, you may not be able to utilize as much of the surface area of the mattress. It is harder to sleep near the edge of some soft mattresses because the edge is not as secure. You may feel like you are going to roll off.  Many companies add a foam encasement to help with edge support.
  • Back Pain– Discomfort and pain in your lower back can occur when your spine gets out of alignment. If you sleep on your side primarily, this will most likely not be an issue on a soft mattress. However, if you sleep on your back or stomach, you may need more support. If your mattress is too soft, your spine can get out of alignment and cause that pain. Still, knowing your preferred sleeping position and exactly how much support you need can help you find a soft mattress to fit you.
  • Movement On The Mattress– It feels very nice to sink into your soft mattress, but this may limit your movements somewhat. You may get the feeling of getting “stuck” in a soft mattress. However, many soft mattresses incorporate bouncier, more responsive foams that give you comfort and pressure relief without this feeling of getting “stuck.”
  • Firmness Is Subjective– I’ve seen people argue about the firmness level of a mattress more times than I care to admit.  Someone might think something is soft, while another person thinks the same mattress is firm.  Keep in mind that another person’s idea of a “soft” mattress may be different from yours.
  • Don’t Ignore Other Aspects Of The Mattress– Don’t just assume that if a mattress is soft, it’s going to be a good fit for you.  You’ll still want to make sure that the mattress has good, durable foams, that it won’t sleep hot, etc.  Once you’ve made sure you like the softness of a mattress, do the extra research to make sure that the other aspects of the mattress are a good fit for you too.

I have a helix. And it is NOT soft. I already know I want a squshy soft mattress. On a scale of 1 to 10. 1 being rock hard and 10 being the softest. I’m looking for an 11. There’s no such thing as being “too soft” in my book. But every thing I’ve tryed promises to be “the best” but end up feeling like a disappointing rock with a bit of fluff on top. Help.

Helix can vary by what you select in their quiz – if you want really soft, I’d take a look at Layla or the softest Amerisleep.

I’m gonna need you to go ahead and start your own blog about testing “soft” mattresses. I feel like the princess and the pea most mornings. New companies keep popping up with their “best mattress” and their testing that makes no sense. I find it all a bit overwhelming.

Is there a mattress that is as soft as a waterbed mattress? For decades I slept on a waterbed until an accident forced me to change to a traditional mattress. I am a “side-sleeper” and sleeping hasn’t been the same since I switched.

I haven’t slept on a waterbed in years, so I’m not as familiar with the feel there. These 4 options here are quite soft though.

It looks very comfortable & want 2 try it If its ok!
