Pocket Mattress – What’s All The Fuss!?


One of the most common questions we get here at Somnior Beds is what is the difference between an open coil spring mattress and a pocket spring mattress.  Well there is a vast difference in terms of comfort and pricing, so here we have an excellent article explaining the make up of the pocket spring mattress.


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

The Counts:
Pocket spring counts are always based on the number of springs in a king sized 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 sized mattress will have proportionately more. Some retailers have started to give the exact count for a particular size which throws a fly into the ointment when you are doing  like for like comparisons.  To keep matters simple and easy, 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 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 in one layer is 2000. Mattresses described as having more than this are utilising one of these techniques double layer construction , 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.

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 OC / CC 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.  And it is this reason alone why the question above cannot be answered with any degree of precision. It is so unlikely a retailer will know what gauge wire is used on any particular unit contained in a particular mattress.

All pocket springs are known as compression springs and can come in various shapes and sizes: The most common shape is the straight metal coil spring, having the same diameter for the entire length. Other configurations include ‘barrel’ types. It has to be said that the actual mechanics of each type of spring used will vary and will have various load deflection attributes for the user.

At Somnior Beds, we use the best pocket spring units to achieve a greater support by ratio and balance this by varying the layers of material we use as fillers. Therefore the combination of these two factors will make for the best combination mattresses you can buy,

We have included the  2000 Cashmere supreme and the Rosebury pocket spring mattresses two top of the range mattresses you can buy. You can check them on our website Somnior Beds.
