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.

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.

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.

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!
