A good night’s sleep starts with the right mattress. From comfort and firmness to the different types of mattresses available, our guide covers everything you need to know about how to choose a mattress that feels just right.

Mattress sizes

Mattress types

Mattress talk can be technical and confusing, so here’s a brief breakdown to help you understand the different types.

Pocket sprung mattresses

Each spring sits in its own fabric pocket, moving independently to support your body and reduce the effect of movement across the bed.

Open coil mattresses

Open coil mattresses use interconnected springs to create an even, supportive sleep surface. They’re a practical, great-value option for everyday comfort.

Memory foam mattresses

A memory foam mattress gently contours to your shape, creating a cushioned feel and helping to relieve pressure. Just the thing if you like comfort that feels close and cocooning.

Hybrid mattresses

Can’t decide between foam and springs? Hybrid mattresses combine different materials, often supportive springs with cushioning foam, to give you a balanced blend of comfort and support.

Orthopaedic mattresses

Orthopaedic mattresses offer a firmer, more supportive feel. They could be the best type of mattress if you prefer sturdy support rather than a softer, sink-in sensation.

Gel mattresses

Gel mattresses combine supportive comfort with temperature-regulating materials. A refreshingly clever choice if you tend to feel warm while you sleep.

Mattress firmness

From soft and sink-in to firm and supportive, the right mattress firmness can make bedtime feel even better. Your favourite sleeping position plays a big part in what feels comfortable. Explore the different firmness levels to find the best mattress for the way you sleep.

What kind of sleeper are you?

First of all, there are no rules. Everyone likes a different level of firmness depending on their personal needs. A lot of it is common sense. If you like a mattress with a lot of support, try something firmer. Habitat offers mattresses to suit medium to firm back support and spinal alignment. Soft mattresses are comfortable for different reasons, but won’t provide the same orthopaedic qualities.

Side sleepers

If you like to sleep on your side, you’ll want to opt for a mattress that’s on the softer side. Soft mattresses have a lot more give, allowing your shoulders and hips to sink comfortably into the mattress.

Back sleepers

For those who sleep on their back, a mattress with a medium firmness is your best choice. This type of mattress provides a good balance of comfort and support, without being too firm or too plush.

Stomach sleepers

Stomach sleepers should seek out a firmer mattress that keeps the body flat and the spine aligned. These mattresses don't have a lot of give, so there's no sinking into the mattress feeling.

Types of mattress covers

The right finish adds the final touch to your mattress. Choose a plain surface and layer on a mattress topper for extra cushioning, opt for quilted fillings for smooth comfort, or try a tufted design that keeps everything neatly in place and helps maintain the mattress’s shape. Then dress it up with bedding you love.
