Pocket Springs

The bottom line:
A mattress:
containing pocket springs is the best you can buy. Far superior than any cage sprung mattress no matter what name they go by.
A mattress: containing a cage or continuous sprung unit is essentially the foundation for a cheap mattress  - If if does not have pocket springs - it is inferior in spring type alone, the most important part of your mattress.
A Mattress: containing the least amount of pocket springs (800) is far better than ANY similarly priced cage sprung mattress. A 1000 pocket sprung unit should really be your minimum standard. It is mine.

What are pocket Springs?
Pocket springs are individual springs contained in a *calico fabric pocket, totally independent of the springs that surround it. Therefore, virtually eliminating  roll together as your body is only using the springs that it needs. If a spring is not being used it stays in the upright (unused) position.

There are three types of pocket spring that are ‘common’ in the construction of a mattress:

Nested Pocket Springs: Linear [Boxed] Pocket Springs; Suspension Pocket Springs.

There is no initial reason to unduly worry about which type you get. They are all relative to the price you’ll pay.
Nested pocket springs look like a honeycomb with the springs being closer together on all ‘sides’. More common on high spring count mattresses but also used in some 1000 counts.. The principle being that the springs are (being additionally supported by its ‘neighbours’ and also offer a more individualised comfort level – more of your body / weight is supported / distributed.

Linear pocket springs run in rows. More common on the lower spring counts Also used to create a firmer foundation.
More or less 1000 pocket springs is classed as a “low spring count” -
1500 to 2000 is classed a “high count “-
2000 upwards is a “very high count”.

Suspension Pocket Springs are relatively new and do not normally have spring counts associated with them (although some do). A premium example of a SPS is The Revolution® used by Harrison’s Beds / Somnus et al, aso referred to as Spring in Spring.  The proposed benefits are that the main spring will take the initial weight and the internal spring will take the surplus thereby equally balancing the weight load.

As a point of note – Suspension Spring Systems should  not normally be counted in the same way as traditional PS, but based on the type of suspension offered. Some manufacturers/retailers are counting one pocket as two springs which theoretically it is – but can confuse when doing comparisons.

The same is true about some 3000 suspension counts. Some of these [known as Air Suspension]  are half height springs taking the space of a full height spring. So two half springs will take up the space of one spring (if you follow me). For mattresses using suspension pockets it is not the spring count that is paramount but the way the system is used.

There are various designs of suspension springs but all essentially doing the same thing by offering ‘progressive support’. This means that the main spring will take the initial bodyweight ‘shock ‘and the smaller suspension spring will adjust to even out the weightload. I personally think they all improve slightly on the traditional single pocket spring. You get a back up support should you ever/or need it. Ideal solution for when there are two greatly differing bodyweights. Light=uses main spring: Heavier=uses main spring and suspension spring.

To confuse matters, but also to clarify. There are numerous other combinations, shapes, sizes etc of Pocket Springs, each system with their own particular attributes. Do not let these confuse you until you come to make your final decision.

There is also ‘Hand Nested’ Pocket Springs. This technique is not common on mass produced mattresses but found on top of range hand made mattresses. In brief, the springs are inserted one by one, or hand formed by rows, and clipped/stitched together  to create a bespoke ‘bed’ of pocket springs. Note: It is worth double checking if you see a description of ‘Hand Nested’ pocket springs that they really are ‘Individually Hand Nested‘ and not a mass produced pocket sprung base (Nested).

For clarification. In the video I make mention that pocket springs are not connected to each other in any way. This is correct in the fact that the actual springs themselves are not connected but, the pockets that contain them are. The fabric pockets are (in most cases) heat sealed and glued to make complete ready to use units. Top end pocket spring units use calico as the casings and these are laced together with twine.

How are Pocket Springs Counted?
The standard way of counting pocket springs is the number of pockets contained in a Kingsized mattress (5’0 x 6’6). A mattress described as having 1000 pocket springs will have 1000 in a king size – proportionately less in a double and proportionately more in a superking. The mattress model name will usually, but not always have the number of springs directly after. Such as Memory Pocket 1000. The more pocket springs in a mattress means the springs get smaller and thinner offering more individual support – The less a mattress contains means they are bigger and wider.

For very high spring counts in excess of 2000 – 3000, they are usually laid on top of each other creating a double unit and then clipped together around the perimeter, These types of mattresses are usuallyin the very top of range of models. But – are they any better? Depends. If the price is negligible for the extra springs then definitely go for it but as I always say – 1500 – 2000 pocket springs are really more than adequate.

Another point of sound reasoning on this topic is that I personally see Vi-Spring as the one of a few ultimate mattress manufacturers in this country and a respected leader in their field (accredited to have invented Pocket Springs) they use 2800 in one of their excellent top of range models (The Magnificence) albeit a double layer, So, I justify my comments by saying, if Vi-Spring uses an average of  1500-2000 counts in many of their models then this count should be more then acceptable for anyone.

The spring count has an impact on two main areas:
Price: The less springs the cheaper the mattress.
Firmness: The more springs in your mattress means the more comfortable / supportive it will be. Less springs means the mattress support will be firmer – but manufacturing techniques can make a 1000 PS mattress feel soft by the use of softer comfort layers..1500 – 2000 pocket springs is more than adequate. Many manufacturers try to have a mattress with more springs than their competitors – currently, in excess of 17000 pocket springs. This is in my opinion, a game of one-upmanship they play between themselves so don’t be dragged into this showcasing game unless you benefit by getting it at a good price.

Also remember that your own bodyweight will dictate the number of springs that will be best for your own persoanl needs. For example, a bodyweight of 10st will have no need or use whatsoever for a spring unit in excess of 1500. Whereby a bodyweight of 16st would be more supported by a pocket count of 2000.

As I have said, a pocket sprung mattress is the best you can get. More springs will give you exceptional individualised support, longevity and comfort -  but in all cases it depends on your bodyweight.  Any pocket spring count is far superior than Any cage spring unit. A 1500-2000 pocket sprung mattress comes in within most manufacturers ‘top of range’ models. Therefore all complimentary components such as waddings and fabrics will also be amongst the best you can get for your budget.

Comfort Layers
Remember, the springs are only the support part of the mattress and they will only be supporting / distributing your bodyweight. What provides the comfort is your choice of comfort layer. Comfort layers can be memory foam, lambswool, cashmere, polyester wadding, High Density foam, latex etc, or indeed a combination or blend of these.What comfort layer/s you choose will have an impact on the price of the mattress. The better the comfort layer, such as latex, the more expensive the mattress will be.

*Calico is a term that is banded about the same way as hoover is for vac cleaners. It is unlikely that calico is used for the pocket spring encasings in mass produced units but more likely a  synthetic [polypropylene] fabric. Top end manufacturers will still insist upon calico or other natural material for their encasings. Our Artisan Naturals 1200 uses calico encased hand nested pocket springs for example.
