How Many Pocket Springs Are in a Good Mattress?

How Many Pocket Springs Are in a Good Mattress?

If you’re looking to buy a new pocket-sprung mattress, you may be wondering “How many pocket springs should there be inside?”. 

While the general rule “the more, the better” is mainly true, there are several other factors to consider, which will affect the overall quality and comfort of your mattress.

In this guide, we’ll answer all the questions you may have when choosing the best pocket sprung mattress for yourself.

What is a Pocket Sprung Mattress?

A pocket spring is an individual spring, which has been encased in its own fabric pocket. This way, each spring moves independently from the others when you lie on the mattress.

As a result, the springs can distribute your body weight more evenly across the surface of the mattress. They also offer better body contour and minimise motion transfer, when your partner moves during the night.

On the other hand, there are mattresses that contain Open Coil or Bonnell springs. They have metal springs, which are interconnected in rows and run down the entire mattress. They typically aren’t good at reducing partner motion disturbance or roll together.

How Many Springs Should a Pocket Sprung Mattress Have?

A decent, firm, high-quality pocket-sprung mattress will typically have 1,000 springs or more. It is essential to note, however, that the more springs a mattress has, the firmer and more expensive it will be.

Don’t settle for a pocket sprung mattress that has less than 600 springs inside. Since they will be larger in size and won’t adapt as well to your body, compared to standard sized pocket springs.

For example, the Silentnight Melrose 1200 Pocket Eco Mattress has 1,221 pocket springs inside the king size. It has advanced body zone support system, which distributes your weight evenly. It’s priced at £699 for a double size and comes with 5 year guarantee.

On the other hand, the Silentnight Hadleigh 800 Pocket Memory Mattress has 816 pocket springs inside the king size. The mattress is 25cm deep and has a layer of memory foam followed by the pocket springs. It’s priced at £529 for a double size, and is slightly less expensive.

Are pocket spring mattresses of high quality?

Yes, pocket-sprung mattresses are an excellent choice for anyone who wants to enjoy a comfortable, well-supported night’s sleep. Here are some of the most important benefits you should be aware of.

1. They last longer

If you’re looking for a durable mattress, look no further than a pocket-sprung mattress with a high spring count; they’re intended to last for many years.

With regular rotating and/or turning, you’ll be able to enjoy your purchase for at as long as ten years without noticing any sagging or dips – much longer than traditional open coil options.

2. They offer advanced support

Individually encased springs in a high-count spring mattress move independently of one another, so they only move where you move to provide targeted support. 

That means no disturbing your companion, advanced body support, and a restful night sleep.

3. They are ideal for people with back problems and aching joints

A pocket-sprung orthopaedic mattress is specially designed to alleviate back, neck, and joint discomfort by reducing stress on these areas. 

back and joint pain

These sleepers require substantial support from their mattress, and the greater the number of springs, the firmer the mattress!

As your weight is evenly distributed across each spring, the mattress will fully support your body and help you maintain correct and healthy sleeping positions, preventing you from waking up with any body aches and pains.

Shopping tip: The Marcello Ortho Comfort Mattress is an orthopedic mattress from Bensons for Beds with 1,000 pocket springs. It offers orthopedic support, relieving pressure from your back, neck and hips.

What Mattress Tensions Are There?

You’ll be able to find pocket sprung mattresses in four mattress tensions: soft, medium, firm and extra firm

The right tension depends on the individual preferences of the person (if they like a softer or firmer mattress). Also, the weight of the person(s) should be taken into consideration.

You don’t want to pick a mattress that is too soft or too firm, you want it to be just right. This way your spine will be naturally aligned when you lay down and your body evenly supported.

For example, Vispring Mattresses have the following guidance when it comes to choosing the right tension:

  • Soft Tension: up to 11 stone (70kg)
  • Medium Tension: 11 – 16 stone (70kg – 102 kg)
  • Firm Tension: 11 – 20 stone (102 kg – 127 kg)
  • Extra Firm Tension: 20 stone (127 kg) and above 

Each mattress brand may have their own specifications, on which tension is most suitable, according to your body weight.


It is understandable that so many people are confused about the spring count in pocket spring mattresses, as this is one of the many aspects on which some mattress manufacturers design and market their products.

As a result of their design, pocket spring mattresses provide a more supportive lying surface that contours more closely to the body of the sleeper than other types of sprung mattresses.

Make sure you pick a mattress that has 1,000 pocket springs (inside the king size). If you have a lower budget 800 can also be sufficient, but ideally the count should be between 1,000-1,400.

After all, you want to buy a high quality mattress, that offers proper body support and will provide you with a good night sleep for several years down the line.
