How Do I Choose A Mattress?

Are you looking for a new mattress? Here are 6 steps to guide you:

  • Plan your budget
  • Pay attention to your preferred sleeping position and your body type
  • Choose the right degree of firmness
  • Choose the right mattress size
  • Test the mattress
  • Find your perfect mattress

1. Plan Your Budget

You spend a third of your life on your mattress. This means that your choice of mattress is an important one. As with most products, you usually get what you pay for.

Sleep Hero divides mattresses into four price categories (according to the standard UK Double size 135 x 190 cm):

  • Cheap mattresses: Under £300

If your budget is low, you should think very carefully about which mattress to buy - and we highly recommend that you test the mattress first. Unfortunately, cheap mattresses are simply not comparable to more expensive ones. You'll find most of the IKEA mattresses in this price range.

  • Mattresses in the lower-middle price range: £300 - £500

You can find some high-quality mattresses in this price range - many of which are well-suited to most people. A good example of a mattress in this price range is the Emma Original.

  • Mattresses in the middle price range: £500 - £700

You'll find some excellent mattresses in this price range, including some of our favourites, like Eve. There are also interesting options with special features, like the muun or the Simba.

  • Premium mattresses: from £700

Luxury mattresses, like the Tempur mattresses, fall into this category. These mattresses are of very high quality but do come at a significant cost.

Sleep Hero Tip: We suggest you invest about £500 for a high-quality mattress. At this price range, you will often find a mattress that meets our quality criteria. Looking to save? Check out our discount codes section for discounts on popular mattresses.

2. Pay Attention To Your Preferred Sleeping Position And Your Body Type

High-quality mattresses are suitable for most sleeping positions and body types. But with mattresses under £300, you should pay special attention to your preferred sleeping position.

In general, people who sleep on their sides require a little more depth as the body only rests on the hips and shoulders. For cheaper mattresses, we recommend that you do not exceed 6/10 in our firmness scale. People who sleep on their backs or stomachs, however, can easily choose a harder model.

Many people believe that a firmer mattress is better for the back. This isn't always true. On the contrary, if the mattress is too firm, it will often cause back and neck pain as it does not allow the body to sink in sufficiently. At the same time, the mattress should not be too soft. A mattress that's too soft will result in the hammock effect, where the hips sink in too much and the spine bends as a result.

In general, the right degree of firmness depends on the type of body. Smaller and light-weight people (up to 70kg) usually sleep better on a slightly softer mattress (up to about 5/10 points on our firmness scale). Heavy-weight sleepers need more support and should, therefore, choose a mattress that's above 6/10 on our firmness scale.

3. Choose The Right Degree Of Firmness

High-quality mattresses that fall in the 5-7/10 points in our firmness scale are suitable for most people and sleeping positions.

Desired firmness is often a matter of personal preference, though, and depends on the level of comfort you experience when lying down. What do mattresses with different degrees of firmness feel like? Our test sleepers know.

4. Choose The Right Mattress Size

Your ideal mattress size will depend on your personal situation. Do you sleep alone or with a partner? Are you very tall or very short? How big is your bed frame? How big is your bedroom?

  • The most common mattress sizes for couples are 135 x 190 cm, 140 x 200 cm, 150 x 200 cm, 160 x 200 cm, and 180 x 200 cm.
  • Singles usually choose mattresses in the sizes 90 x 190 cm, 90 x 200 cm, 120 x 190 cm, 135 x 190 cm, or 140 x 200 cm.
Sleep Hero Tip: If you and your partner share a bed, you don't necessarily need to choose one large mattress. It is also possible to place two smaller mattresses (e.g. 90 x 190 cm) next to each other. You can easily bridge the gap with a love bridge or a mattress wedge.

5. Test The Mattress

It's very important to test whether a mattress really suits you. That being said, it takes the body a few weeks to get used to a new mattress. Testing a mattress for a few minutes in a shop is not enough. When you buy a mattress online, you have the chance to test the mattress risk-free for up to 100 days. We highly recommend that you make use of this trial period. If you don't like the mattress, you can simply return it and get a full refund.

6. Find Your Perfect Mattress

We share our experiences of the mattresses we've tested in our mattress reviews. Here, you'll find all of the information that you may need, such as mattress composition, comfort, degree of firmness, prices, delivery, and the returns policy. Our team extensively tests each mattress and independently assesses the most important factors. This way you'll quickly gain knowledge on tons of mattresses. It's that simple.

Types Of Mattresses

Each type of mattress has certain characteristics, as well as advantages and disadvantages. There are many mattresses available that combine different elements. The best-known mattress types are:

  • Latex mattresses
  • Spring mattresses
  • Foam mattresses
  • Memory foam mattresses
  • Hybrid mattresses (foam + spring)
  • Memory foam with latex coating
  • Gel and foam mattresses

Latex Mattress

Natural latex foam is a material made by the vulcanisation of rubber. Latex combines good body adaptation with high comfort. It also has great natural breathability, which improves the sleeping comfort. Synthetic latex has similar properties to natural latex. The main disadvantage of a latex mattress is its relatively high price.

advantages Advantages

Disadvantages disadvantages

  • Very good body adaptation and point elasticity
  • High degree of comfort - soft/medium-firm feeling
  • Breathable - pleasant sleeping climate
  • Natural latex is an ecological material
  • Recommended to relieve back pain
  • Good durability
  • Pure latex mattresses are quite expensive
  • Smells like chewing gum at the beginning
  • Less suitable for people who sweat a lot
  • Slightly heavier

Spring Mattress

Spring mattresses are the 'traditional' mattresses. They are available in three sub-categories:

  • Inner-spring mattress
  • Pocket spring mattress
  • Tube-pocket spring mattress

The inner-spring mattress is the cheapest model. It is durable and offers a good sleeping environment. But, in terms of comfort, adaptability, and point elasticity, these generally cannot compete with the newer high-quality foam and latex mattresses.

advantages Advantages

Disadvantages disadvantages

  • Durable
  • Stable and sturdy
  • Cooler sleeping climate
  • Great for people who sweat a lot
  • Less suitable for people who get cold quickly
  • Doesn't adapt well to the body
  • Tends to form lying pits

Cold Foam Mattress

Cold foam mattresses are made of polyurethane, a deformable synthetic foam. Cold foam mattresses are very stable and can be made to different degrees of firmness, depending on the density of the foam. There are big differences in quality and price of cold foam mattresses, and caution is advised when purchasing. These mattresses store heat and are best for those who want a warmer sleeping climate or who don't sweat much.

advantages Advantages

Disadvantages disadvantages

  • Suitable for most sleeping positions
  • Highly flexible - malleable in lying areas
  • High body adaptation and point elasticity possible
  • Little motion transfer
  • Durable
  • Stable and sturdy
  • Reasonably priced
  • Very suitable for people who prefer a warmer sleeping climate
  • Has a strong chemical smell at first
  • Flammable
  • Non-ecological - Synthetic material made from crude oil
  • Less recommended for people who sweat heavily
  • Heat and humidity can lead to lying pits

Memory Foam Mattresses (Also Called Visco Mattresses)

Our favourite: the memory foam mattress. This is a polyurethane foam with memory effect: when you push your hand into the foam, it leaves a longer visible impression. Everyone who has tested a memory foam mattress knows that it feels unique. It is highly elastic and adapts perfectly to the body. It has a very high point elasticity and is thus often recommended for people suffering from back and neck pain. It also has a low motion transfer, so you'll be less disturbed at night when your partner tosses and turns.

A high-quality memory foam mattress can be pricey but you often get a very good product that will last many years. Our favourites are the Leesa mattress and the Eve mattress, but we have tested many others that are also very good.

advantages Advantages

Disadvantages disadvantages

  • Suitable for most sleeping positions
  • High comfort
  • Extreme adaptation to body contours
  • Very high point elasticity
  • Low motion transfer - ideal for couples
  • Often recommended for back and neck pain
  • Very suitable for people who prefer a warmer sleeping climate
  • Often more expensive
  • Less suitable for people who sweat heavily
  • Hardens easily in the cold

Hybrid Mattresses (Foam & Spring Core)

The hybrid mattress consists of a combination of foam layers and a spring core. It, therefore, combines the adaptability and pressure relief of a foam mattress with good breathability. The Simba mattress is an example of a hybrid mattress. Tempur also offers a range of hybrid models. These mattresses are complex and usually quite expensive.

advantages Advantages

Disadvantages disadvantages

  • High adaptability
  • Great pressure relief and point elasticity
  • Good breathability
  • Duration - is considered a luxury mattress
  • Complexity

Memory Foam Mattresses With Latex

These mattresses combine the properties of memory foam and latex foam. The latex layers, which usually form the top layers, provide extra breathability. The feeling of lying on latex is different from lying on memory foam - it feels slightly more resilient. A good example of a combination mattress is the Casper.

advantages Advantages

Disadvantages disadvantages

  • High adaptability to body shapes
  • Good breathability - more suitable for people who prefer a warmer sleeping climate
  • High point elasticity

  • Some people prefer the feeling of lying on pure memory foam mattresses
