King-size pocket sprung mattresses

A king-size pocket spring mattress is big on space and even bigger on comfort. It offers plenty of high-quality sleep to refresh you throughout the day. Find out more about these fantastic mattresses with our frequently asked questions.

What size is a king-size pocket-sprung mattress?

A king-size spring mattress measures 5' x 6'6" or 150 x 200cm, so it will comfortably fit a king-size bed. Its larger size makes it a great choice for couples who want a little more room to stretch out without bumping into each other or solo sleepers looking for the ultimate sleep experience.

Find out more about the different sizes available with our mattress size guide.

What benefits does a king pocket-sprung mattress offer?

A pocket-sprung king mattress features hundreds of springs in individual pockets of fabric that move independently of each other when pressure is applied. This makes them a favourite of couples, as you're less likely to be woken up by a partner who likes to toss and turn at night, as the springs help reduce excess movement.

Another great benefit is that the individual springs in a king-size pocket spring mattress also offer a more customised level of support, as only the springs you are lying on will move. This helps to reduce the pressure on your joints and encourages a healthier spinal alignment, reducing the risk of aches and pains. Learn more about this popular mattress type with our handy pocket mattress buying guide!

How many springs are in a pocket-sprung king-size mattress?

There is no set number of springs in a king-size pocket spring mattress; our range features mattresses with various numbers of springs, from 800 to 3000 and more. The more springs a mattress has, the firmer it will be, and vice versa. So, if you're looking for a firm mattress, we recommend opting for more springs!
