Pocket springs are the foundation of high-quality mattresses and are a fundamental component that any mattress buyer should fully understand. The key thing to remember in this section is that pocket springs, types and counts should not be taken in isolation. Read on for all you need to know about pocket springs and why assessing their quality is essential to helping you find the right mattress.

 

 

We have already detailed how cage sprung or open coil mattresses should be avoided at all costs. We have always advocated for high-quality handmade pocket sprung mattresses over mass produced bags of springs, but there’s still a minefield of information on pocket springs which we aim to summarise for you. There are numerous variables that have to be applied in order for you to come to the right decision as to which is best for you.

 

For instance, there is no use having a super duper all singing all dancing pocket spring unit when

1. You don’t actually need it or

2. It is not backed up by an element of substantial upholstery.

 

As you browse through the internet looking for your perfect mattress you will soon see that in most cases great swathes of text is focused on how good the pocket springs are in any particular model, the science behind the design and how you will sleep like a baby. All of this will be relatively pointless if equal space is not designated to the rest of the mattress, the upholstery, the detailing and so forth.

 

The fact of the matter is, a standard pocket sprung unit which forms the basis of many mattresses, will be suitable for practically everyone. It really is! They are not overly expensive and will offer you all the support you will require.

 

 

Pocket spring come from?

 

Much of this mattress years ago in large factories such as Leggett and Platt - Charles Blythe produced.

Also in the following years has been the greatest import and production in Germany.

 

Today, the largest exporter of this type of mattresses Turkey and South Africa.

 

 

Is there a need to be concerned where the spring is manufactured?

 

Not really! These form the basis of lower to mid-priced models and so you are tied to what you can get for the retail price asked. The basis of all spring manufacture is the wire used to make the actual spring and there are limited suppliers of this drawn wire and so assumption can be made that nearly all spring manufacturers will be purchasing from a limited supply chain.

 

 

The basics of pocket springs

 

These comments refer to widely available mass-produced pocket spring units. There may be exceptions to the rule but these will be discussed in the relevant section.

 

The spring counts

 

Pocket spring counts are always based on the number of springs in a king size mattress: 150 x 200 / 5’0 x 6’6. Even when a single mattress is described as having 1000 pocket springs, for example, it won’t. It will have proportionately less. A super king size mattress will have proportionately more. Some retailers have started to give the exact count of a particular size which throws a fly into the ointment when you are doing like for like comparisons. Always be aware of the count in a king sized mattress and you just can’t go wrong.

 

The least number of pocket springs you can get in a mattress is 600.

 

This level of spring count will be in starter or budget ranges of pocket sprung mattresses. This is a good example of the value of a pocket sprung unit, obviously, the retail price will be low but, the quality level of mattress will be significantly better than any mattress utilising an open coil or continuous coil retailing for a similar price.

The most pocket spring units you can get into a king sized mattress on one layer is 2000. Mattresses described as having more than this are utilising double layer construction techniques or they are utilising a suspension pocket sprung unit or they are using mini springs to increase the count. When looking at descriptions and you see a specification with more than 2000 pocket springs you really do have to examine how this was achieved.

As I have said in previous posts, the only differentiating factor between many mattress manufacturers are the springs used. Fundamentally, the springs will more often than not be similar but how they are constructed will provide enough difference to achieve the elusive brownie points that will sway you into thinking their product is somehow better than the competition.

 

 

Guide to pocket springs: A good thing to bear in mind that a 1000 / 1500 / 2000 pocket sprung unit will be broadly similar from about 90% of all manufacturers. It is what is placed on top of the units (upholstery) that makes the difference in Price and in quality.

 

Total spring counts come in usually at 600 / 800 / 1000 / 1200 / 1400 / 1500 / 2000 pockets per unit.

 

The lower spring counts will have a larger diameter spring – The higher spring counts will have a smaller diameter spring. One of the most prolific questions we get asked and abundant on internet forums is the “how many springs are best?”. Now although this is such a simple question the answer is not! The response to this question should always be followed up with “best for what?”

 

 

Best for Price?

 

If you are torn between two similar mattresses one open coil and one pocket sprung the pocket sprung mattress will win hands down! Like I said above, the minimum 600 pocket count is far superior to any open coil or continuous coil mattress you can get. It is so unlikely an open coil/continuous coil mattress will have a quality level of upholstery attached and all these fall within the low-end range of mattresses.

 

 

 

Best for you?

 

If you look at the complete range from Rest Assured, for example, you will see that the bulk of their mattresses utilise a 1400 pocket spring unit. This count will suit the majority of users not too firm and not too soft. A bigger person (such as my 20st Rugby Player friend) will gain more benefit from a 2000 unit. His weight will be equalised over a greater number of springs, The springs will not be fully compressed but allowed to ‘move’ with him. If he was on a 1000 pocket unit, for example, the weight is distributed over a lesser number of springs. Whereas our ten stone friend will be quite happy on 1000 pockets.

 

This is only half the story, though! The other difference between 1000 springs and 2000 springs is the tension of the spring itself. There is no hard or fast rule on what gauge wire is used on a particular spring count: A 2000 unit can utilise a firm spring say 1.5mm  or it can utilise a soft spring say 1.2mm

What’s a Vanadium pocket spring?

 

Vanadium is used in the steel forging process and provides strength to the metal which assists when it is then formed into a spring. It also has a low oxidisation value meaning it doesn’t corrode as quickly as other metals. We use Vanadium on our calico pocket springs that are found in the higher end Artisan models. Vanadium is often found in metal alloys and top end tools to give strength and durability against corrosion. It is used within our springs to ensure they are of the highest quality giving an enhanced lifespan and longevity. Most manufacturers couldn’t tell you what is in their spring wire, you will probably just get shrugged shoulders, but here at John Ryan, we can share with you the exact composition of our calico vanadium pocket springs.
