What are the different types of mattresses?

Pocket sprung mattress

With a pocket sprung mattress, each spring is enclosed in its own cloth sleeve. This makes the mattress responsive to motion during sleep. As a result, these designs are usually available in a medium to firm firmness, promoting good posture for a night of sleep with unbeatable comfort.

Memory Foam mattress

Wanting to feel snuggly in your new mattress? Then memory foam mattresses are for you. The foam in these mattresses make you feel as if you are sinking into your sleep, by contouring to your body’s shape. If you suffer with back pain, then these models give you a good level of support that cushions the joints. 

Hybrid mattress

Also referred to as a ‘combination mattress', hybrid mattresses combine both foam and pocket spring layers, giving you excellent back support and comfort. 

What mattress brands are available?

What’s the best mattress for my sleeping position:

Best mattresses for side sleepers

A good mattress for side sleepers is one that provides lots of cushioning and helps keep your hips and shoulders in alignment while you sleep. A gel mattress may also be a good choice if you're looking for a cooler sleeping surface, but you can't go wrong with a medium or soft mattress, either.

Best mattresses for back sleepers

When you sleep on your back, it is important that you have a higher level of support to ensure your spine is correctly aligned. If this is the case, then we recommend a pocket sprung mattress. Additionally, some people prefer to choose an orthopaedic mattress if they want extra back care. When choosing the firmness of a mattress, we advocate a medium-firm or firm mattress for those who sleep on their backs.

Best mattresses for front sleepers

Front sleepers will need more cushioning than back sleepers, but less than a side sleeper would need. Hybrid mattresses with pocket springs are the most comfortable for people who sleep on their front. In addition, we recommend a mattress that has a medium or medium-firm firmness.

Choosing the best mattress firmness

Every mattress has a comfort grade that ranges from soft through to extra firm. Choosing the best mattress firmness will depend very much on personal preferences and factors such as your size and weight, whether you sleep on your back, front or side, and if you have any back issues.

Firmness ratingPropertiesSuitable for
SoftSoft feel, a lighter-than-air feeling, cushions and cocoons the body to keep it stable and relieve pressure points.
Side and some back sleepers who prefer the softer feel. Lighter and smaller sleepers who may find a firm mattress uncomfortable.
MediumA relatively balanced combination of comfort and support.
All sleepers, including front, back and side sleepers. Average-size sleepers.
Medium-firmSlightly firmer than a medium mattress – may benefit those with back issues who find orthopaedic mattresses too firm.
Ideal for front and side sleepers and those who prefer a slightly firmer feel. Suitable for average-size sleepers.
FirmOften referred to as 'orthopaedic', these are firmer to the touch, offering more support without compromising comfort.
Suitable for front sleepers and those who may benefit from a firmer mattress, such as larger or heavier users.
Extra firmVery firm to the touch, with less ‘bounce’ than softer options. Can be used to aid support for those suffering from back problems.
Suitable for front sleepers and those who are considerably larger or heavier. Not suitable for lighter users, who may find the firmness too rigid.

How much should a good mattress cost?

Mattresses tend to vary in price, mainly depending on how they’re made and what they’re made from. Cheaper mattresses might seem like a bit of a bargain, but they won’t necessarily help you get a good night’s sleep and in the long-term, can cause more problems than solve. To help you set your budget, we’ll look at the average cost of single and double mattresses, according to their main materials. 

  • Pocket-sprung. For a single, you can expect to pay around £200, while a double should cost somewhere in the region of £300 to £400  
  • Latex. A good latex single mattress will typically have a starting price of around £400 and you can expect to pay around £500 to £600 for a double. 
  • Memory foam. Singles start at around £200 to £300, while a double can retail at between £400 and £500.     
  • Orthopaedic. If you’re looking for a single mattress, then a good starting price is around £200. For a double, this can be around £400.
