What is an open coil mattress?

An open coil (or standard sprung) mattress is a supportive, sprung mattress featuring coils of high tensile steel, wound into hundreds of springs and connected by a wire rod edge. 

The spring unit in an open coil mattress works to evenly spread your body weight across the mattress and reduce the build-up of pressure points. Standard sprung mattresses have been around for over a century and remain one of the most popular mattress types available!

Benefits of open coil mattresses

Standard sprung mattresses have remained popular for so long due to the benefits they offer. Below we explain why they remain a firm favourite.

1. Lower in price

If you're looking for a mattress that won't break the bank, standard sprung mattresses offer comfort and support at an affordable price.

2. Highly supportive

Open coil mattresses offer great support as the springs evenly distribute your body weight and relieve pressure where you need it most.

3. Help care for your back

Since this spring system is extremely supportive, it's often used in orthopaedic mattresses. These mattresses have been specifically designed to care for and support your back by relieving pressure and promoting a healthy posture while you sleep.

4. Improve spinal alignment

Since standard sprung mattresses are very supportive, they can help to correct your posture and spinal alignment. This means you'll wake up with less aching joints and feeling more refreshed.

5. Lightweight

Standard sprung mattresses can be quite lightweight. This means that turning or flipping your mattress isn't such a strain on your back.

3. Maximised sleep space

Sealy's Posturepedic Spring System

Within Sealy's Posturepedic Spring System, a coil runs across the entire bed connecting the springs together. This allows the springs to hinge together, offering more personalised support.

1. Personalised support
2. The ability to adjust to your sleeping position
3. Firm edges to help prevent roll-off
4. Pressure point relief and spinal alignment

Is a standard sprung mattress right for me?

Standard sprung mattresses offer excellent support, making them a great choice for most sleepers. Read on to find out how a standard sprung mattress could benefit you.

As well as being supportive, they're also very comfortable. This means your child will get a cosy night's sleep and you can relax knowing they're getting all the support they need.

They're perfect for guest rooms
