Open Coil Vs Pocket Spring Mattresses: Know the Difference


Open Coil Vs Pocket Spring Mattresses: Know the Difference

20/01/2014 / Added By

Buying a new mattress isn’t as simple as it used to be. Here at MyBedFrames, we’ve been asked multiple times now: “What are the differences between open coil and pocket sprung mattresses?” To help you choose the right mattress for you, we’ve put together this quick guide to help you know the differences and get the most out of your mattress.  

What is an Open Coil Mattress?

Open coil (also known as Miracoil, Continuous coil, Standard coil e.t.c) are the most common types of mattresses, which consist of a inter-connected spring system. They are the traditional manufacturing method for mattresses, capable of being  mass-produced with a low production cost – this makes them one of the cheapest on the market. A standard double open coil mattress will contain an average of 300 springs.

What Do I Need to Know?

Manufactures and retailers will often refer to the ‘gauge’ of the mattress– which indicates the thickness of the wire used for the springs. The lower the number, the thicker the gauge, which typically creates a firmer mattress. A 12-gauge mattress will be very firm and provide plenty of support, but if you’re looking for something a little softer go for a 13.5-gauge which still offers plenty of support.

A high-gauge rod edge is very important in open coiled mattresses, as it extends the sleeping surface and and helps the mattress to retain its shape, reducing side sag.

Is an Open Coil Mattress for Me?

There are number of pros and cons with open coil mattresses, which vary in importance depending on what you’re looking for.

Pros: Open coils provide excellent support and are used for most orthopaedic mattresses due to their firmness. They tend to have more ‘give’ than pocket sprung mattresses, and are lighter and therefore easier to turn.  Investing in an open coil mattress with an inbuilt memory foam topper will give a superior level of extra comfort.

Cons: Not as robust as other mattresses and can be known to ‘dip’ in the middle after prolonged use. Open coiled bedding can also lead to the ‘roll-together’ feeling for couples, and you will feel the movement of your partner.

These are great mattresses for children, lasting between 3-5 years before needing to be replaced.  

What Are Pocket Spring Mattresses?

Pocket sprung mattresses offer more support than open coiled. The individual springs that make up the mattress are housed in their own little pockets and work independently of each other. Spring counts can vary dramatically from 600 to 5,000. Typically, the higher the spring count, the better the support.

What Do I Need to Know?

Although the spring count is a factor in mattress quality, don’t be fooled by numbers alone. A mattress crammed with inferior springs will not be better than one with less, more quality springs. Look at the range of specifications including the materials used to top and fill the mattress – this is what is important is defining the quality (and price) of pocket spring mattresses.

Is a Pocket Sprung Mattress for Me?

Pros: Because the springs move independently they offer more support for your body, and are ideal for people of two different weights as pocket-sprung mattresses reduce that ‘roll-together’ feeling.

Cons: Can be heavy to turn, due to the density of their fillings. If you suffer with allergies, be sure to check the fillings carefully, as many use natural materials like lambs wool, which can aggravate allergies.

Pocket spring mattresses can last between 7-10 years.
