Back Sleeper

For back sleepers, spinal support is the top priority. Although sleeping on your back provides benefits for spinal alignment, the right mattress makes a huge difference.

We recommend

Front Sleeper

If you are a front sleeper, it’s imperative that you choose the right mattress and support for your body. This is because sleeping on your front can cause straining to the neck, and causes back pain.

Frequently Asked Questions

If you cant find the answer to question in our FAQ’s, then simply ask it below and one of our expert team will answer it for you.

Which Mattress Type is Right for You?

Check out our mattress type guide to find the best type of mattress that fits your preferences.

Memory Foam Mattress

Now completely unlike the original foams, this is ideal for those who want excellent support, enveloping the body. Foam can be produced in various densities to create different firmness levels.

Recommend for people who want...

Less bounce and more comfort. Foam can get warm relative to other mattress types, but it is still hugely popular.

Pillow Top Mattress

Perfect for those who want comfort and support. A Pillow Top mattress has a looser top layer, offering more comfort. Like sleeping on top of a good mattress, but on top of a luxury duvet.

Recommend for people who want...

The support of a firmer feel, but still want that cloud-like 'ahh' feeling when climbing into bed.

Latex Mattress

Derived from a rubber plant, this is completely natural and moulds to the body’s contours without requiring heat to soften. If looked after, a latex mattress could last 20+ years.

Recommend for people who want...

A natural alternative to memory foam, durable and with instant support and cooling properties.

Coil Mattress

The traditional, original spring used in mattresses for many years. Extremely durable; Open Coil springs are an open mesh of springs, sharing bodyweight across the entire mattress.

Recommend for people who want...

This type of spring has been in production for over 100 years and is still going strong. Great value for money.

Pocket Sprung Mattress

Pocket Springs act like pistons, moving up and down to mirror the contours of the body, providing excellent support. Each spring is independent, so there is no compromise.

Recommend for people who want...

Excellent support. Pocket Springs are made in different firmness levels, but generally offer the best support.

Geltex Mattress

A relatively new material, Geltex is a cross between Latex and Memory Foam. Geltex remains cool and responds instantly, but is much more affordable than Latex.

Recommend for people who want...

A comfortable mattress. Geltex is soft, quick to move and return to its natural shape and offers good support.
