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 a soft mattress?

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. 

Understand that there are advantages and disadvantages of purchasing softer beds, but overall 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:


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.


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 a 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 bedspread 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. If you are worried about the softness of your bed and if it’s the reason for your bad back, check our guide on ‘Can a soft mattress cause back pain?’

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.


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.

Why mattress toppers are a good choice?

Are you wondering if this is a bedding item you need? The answer is yes, yes and yes! A mattress topper is always an excellent suggestion because it can soften many different types of mattresses. If your older bed is already starting to lose its integrity, this can be a good solution for you to get a good night’s rest without breaking the bank.

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.

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.
