We all have our own preferences when it comes down to mattress softness, but you have to consider a few things before you dive into the world of soft mattresses just because you prefer to sleep on a softer surface. Soft mattresses are not a one-fit-all solution. They are much better suited towards lighter individuals and by lighter we mean usually people who weigh under 6 stones.

Why are saying this? Well, we just want to prepare you in advance and help you make the best choice for your and your specific circumstances. If you weigh over 8 stones you might be better off looking into medium firm to firm mattresses instead.

Having said all that, how do you choose?

Today the UK market is overflown with products. However, not all manufacturers and models provide appropriate support and comfort. That’s why making a decision can sometimes be overwhelming if you don’t know where to start.

That’s why we created LightSleeper – to help you choose the product that is right for you and you alone, and help you make that choice along the way. Companies can never pay to feature their products on LightSleeper, nor we are getting paid to recommend one product over the other – we are an independent resource and we only recommend products that have passed our tests and we feel that they are the best in their category.

So let’s see what we think are the best soft mattresses in the UK today and why.

How to choose the best soft mattress for your needs?

Nowadays, lots of brands will say many things about their products to distract you so that you buy what they are offering. For example, a company may say that their mattress is “the most comfortable” or “the most supportive”, but that doesn’t necessarily mean it’s true. 

People look for different features, meaning all of this can be subjective. However, there are some factors you’ll want to focus on to receive a good night’s sleep. They are the following:

Support

One of the first things that you should take into account when making this type of purchase is support. You shouldn’t mistake firmness for support because a softer option can still be supportive.

The level of support determines your spine alignment and the pressure points between your body and the bed. When you’re looking for options, take a look at the supportive properties a mattress offers. Making the right choice can provide you with a restful night’s sleep, and it can even alleviate back, hip, or shoulder pain.

Materials

The materials used in a mattress can significantly affect the quality of your sleep. They should play a significant role in your choice.

Construction matters, which is why softer beds often use firmer materials. If you’re looking for a softer mattress, you’ll have to make sure the materials it is crafted from are durable and long-lasting. That’s because your choice may affect the performance across all other categories such as pressure relief, motion isolation, edge support etc.

Cooling Properties

Some materials used in the crafting of a bed tend to trap heat, while others wick it away.

When it comes down to temperature, you should think about your preferences. If you always need a ton of blankets that will keep you warm, you are a cold sleeper, and memory foam mattresses might be a good option. Whereas if you’re a hot sleeper, you’ll need a product with ample airflow of cooling properties. 

If you’re somewhere in between, make sure your purchase is breathable, so that you are comfortable during all four seasons.

How to choose the best soft mattress?

Motion Isolation

This is a feature that can be extremely beneficial if you’re sharing the bed with someone. Motion transfer usually occurs when movements from one part of the bed spread across the entire surface. Some mattresses absorb motion better than others.

Look for options that might prevent a sleeper from feeling the movement when their loved ones toss and turn in their sleep.

Pressure Relief

Pressure points occur regularly when you make contact with a mattress. However, products with more contouring may relieve these pressure points. They can do that by cradling your body for even support and cushioning so that you get pain relief in your neck, shoulders, back and hips.

Edge Support

Not all mattresses provide good edge-to-edge support. What we refer to is the sturdiness of a bed’s perimeter. For example, if you get closer to the edge, you may feel like you could accidentally roll-off. Sometimes you can even have trouble getting into or out of your bed due to weak edges. However, a sturdy, reinforced edge will allow you to use the whole sleeping surface.

Price

Mattresses can range from a few hundred dollars to several thousand dollars. Depending on your budget you can find quality options in most price ranges. However, the cheaper the mattress, the more you’ll have to spend on other sleep accessories like toppers and pillows to get a comfortable night’s sleep.

We advise you to look at options before setting a budget because you want to find the perfect balance between the price point and all the benefits that come with it.

Can I make a firm mattress softer?

Can you make a mattress softer?

In general, mattresses naturally soften over time, which means they might change on their own. However, this may take years, and by then, your bed can have many lumps and sags.

There are a few ways you can make a firmer mattress softer. For example, a box spring can make memory foam feel firmer, which means that you might soften the feel if you remove it. Another option is adjusting your mattress foundation. However, make sure to read the manufacturer’s information before doing it, so you don’t risk voiding the warranty.

Also, if you’re sleeping on a memory foam product, you can amp up the temperature in your bedroom, which may soften the bed slightly.

And finally, your best bet and our recommendation is getting a mattress topper that will definitely soften the sleeping surface. If you want to learn more about the subject, take a look at our guide about “Best Mattress Toppers for 2021.”

What problems can a soft mattress cause?

What problems can a soft mattress cause?

The mattress firmness you choose can depend on your sleeping position, body weight and personal preferences. Understand that every firmness comes with its own problems, and that’s why you should find one that works for you. Firmer mattresses aren’t always the solution!

With that said hot sleepers need to remember that soft options typically allow your body to sink in deeper, wrapping around you and possibly making you overheat. If you tend to sleep hot, maybe choose a different firmness and get a soft mattress topper instead.

You can be faced with another problem with weight. Heavier people may sink in too much and end up putting unnecessary pressure on your joints. Yes at the end it comes down to personal preference, but if your weight is above 8-10 stones, we suggest you opt for a medium-firm or firm mattress to receive proper spine alignment.

Your sleep position can impact your firmness choice as well. Back, side and combination sleepers can use softer products, but we don’t recommend them to stomach sleepers due to potential sinkage.

The last issues you can face is the price. Since soft mattresses are one of the hardest type to make, they have many materials inside them with multiple foam layers that drive up the price.

Can a soft mattress cause back or hip pain?

Can a soft mattress cause back or hip pain?

Excessively soft mattresses can come with the possibility of back and hip issues.

If a mattress is too soft to support your hips and shoulders properly, your body might sink in too deeply, which can lead to joint pains and a bad back. It can also place additional pressure on your spine and cause body aches.

A soft option might overcompress under the hips and create pressure points. Thus if you’re struggling with chronic pain or have back and hip problems, you should opt for a firmer mattress to receive the fantastic pressure relief you deserve!

Is a mattress topper a good choice?

Is a mattress topper a good choice?

Yes, yes and yes! A mattress topper is always a great suggestion because it can soften hybrid mattresses, latex mattresses and even ones with a layer of memory foam.

If your older bed is already starting to lose its integrity, this can be a good solution. However, a topper should be matched with reliable support below, which means it’s essential to account for the capabilities of your own mattress.

Generally speaking, mattress toppers are recommended for firmer beds to help compensate for comfort while not jeopardising the support. With that said if your bed is soft, maybe you should invest in a high-quality pillow instead.

Final Words

Finding a supportive soft mattress can be challenging, but you have to remember to find the right balance between support and softness to get a refreshing and peaceful night’s sleep. Think about the materials, support, motion isolation and cooling properties so that you can find the right bed for you.

We might not be professionals, but we’ve tested, researched and commented on every product we’ve put on this list. With that said, we hope that this article was helpful, and you were able to find what you are looking for.
