Best Soft Mattress UK

Soft mattresses are growing in popularity because of the many benefits they offer. If you are a side sleeper or are struggling with restless nights, a soft mattress would do the trick. This is because they are designed to provide the right cushioning and conform to your body’s natural shape.

Soft mattresses come in different designs and sizes, and you just need to find the right one for your needs. If you are looking to enhance your sleeping experience, this guide will help you choose the soft mattress from the best models in the market. Below is also a quick buying guide to help you find the perfect mattress for your needs.

How to Find the Perfect Soft Mattress

Construction Type

When shopping for soft mattresses, it is important to consider the type of construction. Soft mattresses are available in different construction types including memory foam, pocket sprung, hybrid, and latex.

Most soft mattresses are made from memory foam material which is great for providing support for people with joint pain and allergy. However, because of their deep sinking effects, memory foam tends to become quite hot and un-breathable.

Pocket sprung mattresses come with separate springs housed in fabric pockets and are designed to offer additional support to the body. Latex mattresses have a solid feel than memory foam and are springier.

They are a common choice because they help regulate temperature and have natural antimicrobial properties that make it a good choice for those with asthma and allergies.

The other type is hybrid mattresses which conform well to the body and ensure temperature neutrality. However, most of the hybrid mattresses are on the firmer side.


Essentially, softer mattresses have more layers to offer more comfort. However, this makes the mattress heavier and can be very difficult to move.

Luckily, soft mattresses with construction type like memory foam are usually lighter than models such as those with inner springs.


Of course, you want to ensure that you sleep on a comfortable mattress that will improve your spine alignment.

Sleeping on a mattress that causes improper alignment can result in discomfort, pain, and aches. Different mattresses offer varying comforts, so choose the most suitable one based on your preference.


Some soft mattresses tend to come with breathable covers for air circulation. So if you sweat a lot at night, you should consider this factor so that you enjoy a cool night sleep.


The other thing to take into account when making your purchase is the size of the soft mattress. Typically, soft mattresses come in sizes like small single, single, small double, double and king size.

If you are sharing the bed with your partner, make certain that the mattress is wide enough to accommodate your different sleeping positions. It is wise to measure your bed first, so you can have an idea of what size of the mattress to get.

Trial Period

Some manufacturers provide 100-day back money guarantee for their products, so consider this when making your selection. A mattress that comes with a trial period allows you to send it back if it does not meet your requirements. However, it’s important to note that most handmade and traditional mattresses do not have trial periods

Frequently Asked Questions

Who are soft mattresses designed for?

Ideally, soft mattresses are designed for restless sleepers who find it hard to get sleep as it provides more comfort than other types of mattresses.

If you are a side sleeper, a soft mattress would also be a good choice because it helps align the spine correctly and prevents you from waking with pains and aches.

Because soft mattresses are designed to sink deeper, they are good for those who experience hip and other joint pain problems. This reduces any pressure and discomfort that you may feel while sleeping on hard mattresses.

They are also designed for lightweight individuals and children. Because children’s bones are still growing, soft mattresses can help align their spine as they sleep and ensure proper posture.

What sizes are available for soft mattresses?

Basically, soft mattresses are available in sizes such as small single, single, small double, double and king size.

Are softer mattresses suitable for heavy people?

No, soft mattresses are only suited for below-average and above-average individuals. This is because they tend to sink much, and this helps to relieve pressure points on the bodies of average weight individuals more than firmer mattresses would.

People who weight above average tend to sink more deeply into softer mattresses, and this makes them uncomfortable. Also, the sinking effects of softer mattresses can lead to pressure and pain in heavier individuals.

What is a pocket sprung mattress and what is it used for?

Just as the name suggests, pocket sprung mattresses consist of up to 3000 springs that are placed in fabric pockets.

The springs are designed to move independently to offer more support to the body. What’s more, the springs come in different tensions like soft, medium and firm, and this helps to support individuals of different weights.

However, a downside of pocket sprung mattresses is that they have a high density, and this makes them difficult to turn. Also, most of them are packed with natural materials like lambswool that are likely to aggravate the allergy.

Are soft mattresses good for stomach-sleepers?

Most people who sleep on their stomach find soft mattresses uncomfortable to sleep on. Since the mattress sinks beneath, it causes one to turn their head so that they don’t sleep facing down.

This can lead to pressure in the neck and shoulders, causing discomfort during the night. Additionally, stomach sleepers with a heavier weight may feel uncomfortable sleeping on soft mattresses.

Does a soft mattress require turning?

Some soft mattresses require turning while others just need rotating. So this goes down to your personal preference. If you are considering purchasing a heavy or large mattress, opt for one that comes with side handles to make turning easy.
