How To Choose The Right Mattress For You

Choosing the right mattress can make a huge difference to your comfort and sleep quality. In this guide, we explain how to choose a mattress that suits your sleeping position, comfort preferences and bedroom space.

Start by choosing the right mattress size

Before thinking about comfort or materials, it’s important to choose the correct mattress size for your room and sleeping needs.

Common UK mattress sizes include:

If you share a bed or tend to move during the night, choosing a larger mattress can make a noticeable difference to comfort.

You can explore our full range of mattresses, bed frames and divan beds to find the right size for your bedroom.

Choosing the right mattress size for your bedroom

Consider your ideal mattress firmness

Mattress firmness is one of the most important factors in achieving comfortable and supportive sleep.

While comfort is personal, here are some general guidelines:

Soft mattresses
Best for lighter sleepers and those who prefer a plush feel. They allow the body to sink slightly into the surface.

Medium mattresses
A popular choice for many sleepers. They offer a balance of comfort and support.

Firm mattresses
Provide more support and are often preferred by back sleepers or those who want a sturdier feel.

If you share a bed, choosing a medium or medium-firm mattress can often suit both sleepers.

Our experienced in-store teams in Grantham and Boston are always happy to help you try different firmness levels so you can find what feels right for you.

Understand the different types of mattresses

Modern mattresses are designed using a range of materials and technologies. Understanding the differences can help you decide what will suit your sleep style best.

Pocket Sprung Mattresses

Pocket sprung mattresses contain individual springs that move independently, helping to support different parts of the body.

Benefits include:

  • Good support across the body

  • Reduced motion transfer for couples

  • A traditional mattress feel

Many respected brands such as Hypnos, Relyon, Harrison Spinks and Highgrove specialise in high-quality pocket sprung mattresses.

You can browse our range of pocket sprung mattresses to see the options available.

Memory Foam Mattresses

Memory foam mattresses mould gently to the shape of your body, helping to relieve pressure points and promote comfort.

Key benefits include:

  • Body-contouring support

  • Pressure relief

  • Reduced partner disturbance

Brands such as Tempur and Kaymed are well known for their advanced memory foam technologies.

Hybrid Mattresses

Hybrid mattresses combine pocket springs with layers of foam or other comfort materials.

This combination can offer:

  • Responsive support from springs

  • Pressure relief from foam layers

  • Balanced comfort for many sleepers

Brands including Sealy and Silentnight offer innovative hybrid designs that combine comfort with reliable support.

You can view our hybrid mattresses to see these options.

Think about your sleeping position

Your preferred sleeping position can influence which mattress will feel most comfortable.

Side sleepers
Often benefit from slightly softer mattresses that cushion the shoulders and hips.

Back sleepers
Usually prefer medium to firm mattresses that support the natural curve of the spine.

Front sleepers
Often need firmer support to help prevent the hips from sinking too deeply.

If you change position during the night, a medium mattress is often a good all-round choice.

How the right mattress can help you sleep better

A mattress that provides the right balance of comfort and support can make a noticeable difference to how easily you fall asleep and how well you stay asleep.

Features that can contribute to better sleep include:

  • Pressure-relieving comfort layers
  • Responsive pocket springs that support the body
  • Reduced movement transfer for couples
  • Breathable materials that help regulate temperature

Don’t forget about temperature and breathability

A comfortable mattress should also help regulate your temperature while you sleep.

Many modern mattresses include breathable materials such as:

  • Natural fibres

  • Cooling foam layers

  • Airflow spring systems

Brands like Harrison Spinks, Hypnos and Enchanted House often incorporate natural materials such as wool, cotton and cashmere to help create a comfortable sleeping environment.

Pairing your mattress with the right pillows, duvets and bedlinen can also help improve your sleep comfort.

Creating the ideal sleep environment

While your mattress is the foundation of a comfortable bed, your overall sleep environment also plays an important role in how well you rest.

To support better sleep, consider:

  • Choosing a supportive mattress that suits your sleeping style

  • Using comfortable pillows that support your neck

  • Selecting breathable duvets and bedlinen for the right temperature

  • Keeping your bedroom calm, dark and comfortable

Making small improvements to your sleep environment can help you enjoy more restful nights and wake up feeling ready for the day ahead.

When should you replace your mattress?

Even the best mattress will eventually need replacing. Over time, materials can lose their support and comfort.

Most experts recommend replacing your mattress every 7–8 years, although this can vary depending on quality and usage.

Signs it may be time for a new mattress include:

  • You wake up with aches or stiffness

  • The mattress feels uneven or sagging

  • You sleep better in other beds than your own

  • Your mattress is more than 7–8 years old

If you notice these signs, it may be worth exploring our range of mattresses to find a new model that better supports your sleep.
