Buy Pocket Sprung Mattress

Pocket sprung mattresses are a highly popular option, combining great support with pressure relief. The best pocket sprung mattresses UK offer exceptional mattress support for a great night’s sleep. In addition, they help isolate movement and react independently to each sleeper’s needs, meaning no matter what size or shape you are, your mattress can adjust to your sleeping position correctly.

But is a pocket sprung mattress the right choice for you?

At Winston’s, we understand that buying a mattress can be an exhausting task, especially if you don’t know where to start. That is why we have developed several easy-to-read articles that will guide you through the world of luxury mattresses. This buying guide will give you all the information you need, from the benefits of a pocket sprung mattress to its construction and spring content.

What Is A Pocket Sprung Mattress?

If you have just started looking for a new mattress, you may have read the term pocket sprung many times. However, it can be unclear when understanding the different spring types and support levels of a new mattress.

A pocket sprung mattress comprises individually fabric encased springs to offer more personalised support to the body. Each pocket spring acts independently depending on where the pressure is applied; if you are a side sleeper, then the pocket springs around your lumbar region will support you without the entire spring system needing to compress. You may have endured the open coil spring in other mattresses, where you go to move over, and the whole bed moves and shakes. Pocket sprung mattresses eliminate this sleep issue as the construction ensures that the base only reacts to pressure placed on specific areas rather than moving uniformly.

Pocket mattresses are great for couples as they prevent roll-together, reducing movement transfer in the process. For restless sleepers, pocket sprung mattresses provide total body support and aid in achieving an uninterrupted night’s sleep.

Pocket sprung mattresses reduce roll together (where the mattress rocks when one sleeper moves) and can be fully tailored to your exact sleeping requirements.

What are the Benefits of a Pocket Sprung Mattress?

No transfer of movement
  • Unlike open coil springs, pocket springs work individually. This means that each spring will react differently to movement, significantly reducing the chances of disturbing your partner when they’re sleeping.
Consistent firmness
  • There is an even level of tension across the whole mattress due to the springs being wrapped individually.
Total body support
  • Because each spring works independently, they provide full-body support. Our Winston’s mattresses use 3D mini springs, which supply a 7 zoned support. This is good as it reduces the chances of aches and pains.
Pressure relief
  • The support provided by the pocket spring system reduces the amount of pressure point build-up, therefore reducing the chances of aches and pains.

What is Pocket Spring Count?

Pocket sprung mattresses use spring counts to indicate the number of springs and, therefore, the quality of support you will be getting. For example, in a kingsize pocket sprung mattress UK, a 1000 pocket sprung mattress is the minimum number of springs you should opt for; however, you should be aiming for a 1500 pocket sprung mattress or a 2000 pocket sprung mattress. Any less, and the springs get bigger and more unsteady.

At Winston’s Beds we do spring counts into the thousands using patented 3d 7-zoned micro-coils. Given that our mattress depth is at a minimum of 30cm, we can add more layers of springs and upholstery; therefore, the mattress comfort ends up with a perfect balance between the mattress support and the comfort layers.

Are More Pocket Springs Better Than Less?

Though many retailers will tell you more springs are just a selling point, mattress spring count must be carefully considered. For example, if you see a retailer stating a 1200 pocket sprung mattress is better than a 5000 pocket sprung mattress, then be cautious, so you don’t end up falling for the spring count scam. The rule of thumb is simple, the more quality springs you have, the more support you will receive.

Are Pocket Sprung Mattresses the Best for a bad Back?

Pocket sprung mattresses are excellent if you have a bad back and struggle to sleep at night. This is because each spring reacts independently based on your sleeping position. Furthermore, Winston’s Beds pocket springs can be chosen to your precise body weight and sleeping position, meaning that the mattress will offer the absolute support level you need.

Best Pocket Sprung Mattress for Side Sleepers

If you are a side sleeper, then the mattress you choose should be suitable for side-sleeping, but it’s remarkable how few people acknowledge this. It’s not helped by the fact that there’s a lot of obscure advice in stores and online about which pocket sprung mattress is best for side-sleepers.

If you are a side sleeper, that does not automatically suggest you need a particular mattress brand. Commonly side-sleepers are best suited to softer mattresses, and there are many mattresses on the market suitable for you. Softer mattresses are better for side sleepers because your body’s shape around the lumbar and shoulders is contoured, and this will dig farther into the mattress itself.

It also depends on your weight – if you are on the heavier end of the spectrum and you are a side sleeper, you may find that a slightly firm mattress will work better. To make it simple for you, we have created a mattress firmness table from decades worth of data to guide you to what mattress firmness is best for your weight and sleeping position. All of our mattresses are suited to any sleeper.

Are Pocket Spring Mattresses Firm?

The spring unit directly equates to the overall firmness or feel of the mattress, whereas the upholstery layers affect the comfort.

So if you’re looking for a firm mattress, you can choose a pocket sprung firm mattress, which is achieved by using a 1.6mm spring gauge. However, selecting the wrong spring can cause significant sleep problems and discomfort. This is why we have created a comfort chart to help you choose the best firmness for your weight and sleeping position.

Which is Better Memory Foam or Pocket Sprung Mattress?

The quick answer is pocket sprung. Whilst support and comfort are subjective, the manufacturing quality of a pocket sprung mattress vs memory foam mattress is considerable. In addition, pocket sprung mattresses reflect a considerably higher build quality than foam mattresses.

With the most mattress in a box brands such as Emma Mattress and Eve, memory foam offers a one size fits all firmness level; this is the biggest difference between pocket sprung and memory foam mattress as there’s no way you can pick a customised foam tension like you can do with a pocket spring.

Pocket springs are also much more breathable than foams allowing better airflow, keeping you a lot cooler at night, especially if you’re a hot sleeper.

However, if you are set on a foam mattress, we recommend a pocket sprung latex mattress to get the best of both worlds.

Open Coil or Pocket Sprung Mattress

The open coil is the most basic mattresses, consisting of an inter-connected spring unit. They are the traditional construction method for mattresses, capable of being produced on a mass level with a meagre production cost – this makes them the most affordable on the market. A standard double open coil mattress will contain an average of no more than 300 springs.

Pocket sprung mattresses spring system moves independently and so they offer much more support for your body and are perfect for people of two different weights as they reduce that ‘roll-together feeling. However, an open coil mattress is not as robust as their pocket sprung counterpart and are notorious for dipping in the middle after short use. Open coiled mattresses also lead to the ‘roll-together feeling meaning you will feel the movement of your partner.

How to Choose a Pocket Sprung Mattress

Buying a new mattress can be a daunting task considering there are well over 6,000 different mattress models on the market. When choosing a new mattress, you need to find out the following information.

  • How many pocket springs are there in the mattress?
  • What spring tension do I need based on my body weight and sleeping position?
  • What mattress upholstery fillings and gsm amount does the mattress contain?
  • Are the upholstery layers soft, medium or firm feel?
  • Is the mattress double-sided?
  • What is your budget?
  • What’s the guarantee? (anything less than 30 years on a mattress over £1000 is unacceptable)
  • What’s the trial period (anything less than 200 nights is useless as it takes around 12 weeks for the mattress to settle and your body to adjust)

Frequently Asked Questions

A typical double mattress pocket sprung contains at least 1000 springs, and a king size mattress will contain a higher spring count and so on. It is unlikely you will see a pocket sprung mattress with more than 3,000 pocket springs as a core unit.

Higher spring counts can be achieved by using mini springs which go above the core spring unit for a non-turn mattress or above and below for a two-sided mattress. Here at Winston's, our mattresses can contain anywhere from 1500 springs up to 13,500 total springs.

At the core of every Winston's mattress is a fabric pocket spring system, layered above and below with 2000 pocket springs in each separate layer (dependant on the type of mattress you choose). These springs work independently of each other, adapting to each person's unique sleeping position and body shape. Our mattresses provide the best value for money on the market and give the correct amount of support needed for a great night's sleep.
Pocket spring mattresses last between 8 to 10 years on average, although this can be extended with the right amount of care.

A pocket sprung mattress also requires regular flipping to reach its full lifespan, a Winstons pocket sprung mattress will last you a lifetime due to our high quality build and this is why we offer a 30-year guarantee with every mattress.
Pocket sprung mattresses come in soft, medium, firm and extra firm comfort grades and can be tailored to suit your specific sleeping requirements.

Due to the independent movement of the individual spring, pocket sprung mattresses are among the best mattress types for back pain, depending on your requirements.

Pocket sprung mattresses can be put onto a slatted bed safely. However, for optimal functionality and comfort, it’s recommended that significant sheeting is placed over the slats.

If your bed has wooden slats, pocket sprung mattresses can still provide all the comfort you need.
