We’re often asked the question what’s the difference between an Open Coil vs Pocket Sprung mattress? So, we’ve decided to create this comprehensive guide for members of the British public.

Firstly, it’s important to remember that buying a new mattress isn’t as straight forward as it used to be. There’s a whole range of specifications and options to choose from. Generally open coil and pocket sprung are common types of mattresses which are made by most brands and companies across the country.

As we’re all different shapes and sizes, choosing the correct item for your needs is extremely important for a refreshing nights sleep. So, let’s begin!

Coil Sprung Mattress Explained

An open coil mattress is also known as standard coil, Miracoil, bonnell springs and continuous coil. These feature a traditional spring system with a continuous coil connecting the entire structure. There’s usually a wire rod edge which goes around the top and bottom of the unit. The springs ‘inside’ are then connected at each end. This means the whole structure moves as one unit.

Sprung open coil items tend to be mass-produced, they’re usually cheap and can feature a wide array of filling options. Typically, you’ll find that most bed retailers will often talk about the ‘gauge’ of the mattress. This basically relates to the thickness of the wire – which is used for the springs. For example, a 12-gauge mattress tends to be firm, whereby a 13 gauge will be softer.

Pros and cons of Open Coil Mattresses?

Generally, they will provide the sleeper with great support throughout the night. If you like to ‘turn’ or ‘rotate’ your mattress, this type of item will be easier to move than a pocket sprung – as they’re lighter. However, there’s also a downside, they’re not as robust as other types of mattresses on the market, they can also ‘dip in the middle’ after prolonged use.

Equally if two partners are sleeping together, because the springs are connected throughout the whole structure, two people can ‘roll together’ more easily. This means you may disturb the person sleeping next to you, or when one gets up to go to the toilet or for a drink in the middle of the night, the whole bed can ‘move’.


Pocket Spring Mattresses Explained

If you’re thinking about purchasing a brand-new mattress, a pocket sprung might be ideal for you. This type of item has become popular over the past decade or so.

The spring system is designed to offer high-quality support and to aid a restful night’s sleep, thanks to targeting those pressure points of the body. The name gives away what the product is, it’s a spring housed in its own fabric pocket!

These springs move independently eliminating roll-together between two partners and offering tailored support. This basically means should a partner move in the middle of the night; the other person shouldn’t be ‘disturbed’ – as their springs are supporting their own body weight.

As you can see, the individual springs differ from coil spring products for an enhanced sleep after a hard day’s work. Pocket sprung items are also available with man-made fillings and natural materials. These can be present above or below the spring system, sometimes they can be both! You’re able to purchase fillings such as memory foam, latex foam, horsehair, reflex foam and more!

Advantages and disadvantages of Pocket Sprung Mattresses?

As they work independently they can offer more tailored support. This can be ideal if two partners are different weights or sizes. They’re also produced by nearly all bed manufacturers, meaning there’s a huge choice to choose from. This also means the price has decrease over the last few years, making them even more affordable for the average person.

As with most things in life, there is one or two downsides. The main problem relates to their weight. This means they can be heavy to rotate or turn due to their fillings and spring system. Normally for a standard double this causes no ‘real’ issues, however for larger sizes such as a king size or super king it can be more

Quick Tip

A pro tip to remember is most retailers state their spring counts on the king size model. For example, let’s say an item features 2,000 pocket springs, this may be lower in a standard UK double or a single. Equally there may be higher spring counts in a super king.

If you suffer from allergies, it’s recommended to check what fillings are included as some can feature lamb’s wool, cotton and so on.

How long do mattresses last for?

With general ‘wear and tear’ a UK mattress will last for around 7 years. If cared for correctly they can last for 7-10 years, however this does depend on several factors.

When you receive your new item, it’s important to read all the documentation carefully. This will detail if your product is a non-turn item or turn-able, if it recommends to rotate or specific ways on how to clean. You should also try and not ‘sit’ on the edge of the mattress, over time this can ruin the shape and structure – resulting in a substandard night’s sleep.

If you find yourself ‘tossing and turning’ or feel unrested when you wake up, it may be time to change! If you’ve found this Open Coil vs Pocket Spring guide helpful, please share it with your friends and family!
