We all spend at least a third of our life on a mattress, and we’ve all experienced what it’s like trying to sleep on an unsuitable one. Not only does an uncomfortable mattress affect your sleep, but your whole life, too. The wrong one can lead to relationship problems, physical pain, and sleep deprivation. Having poor quality sleep has a myriad of health implications, both physical and mental. Put simply, if you want to live your best life, finding the best mattress is a good place to start. But with so many options on the market, this task can seem impossible.

To make a successful mattress purchase, consider things like materials, firmness, sinkage, and bounce. You also need to think about factors which are entirely personal to you, such as sleeping position, your natural body temperature, whether you share a bed or not, and other similar preferences.

Offering expert help and advice, we strive to help you decide how to choose a mattress in the UK. Let’s start with our mattress reviews of the top options you can choose from and discover our pick for the winner.

Silentnight Studio – (Best For Side Sleepers)

Silentnight Studio

The Silentnight Studio mattress comes in three different comfort ratings: soft, medium and firm. For the purpose of this review, we’re focusing on the medium

This item is constructed of three distinct layers. The top is the comfort layer, which is gel-infused and offers an elastic, bounce-back feeling. This layer also helps keep the mattress cool. The second layer is memory foam, which helps reduce pressure build-up and adequately support the body. The base layer is a high-density foam core, which gives it more structure and provides firmness and support. The cover of this item is approved by Allergy UK. It has a fresh, comfortable feel, too.

It feels quite distinctive and pleasant thanks to the combination of the gel-infused top layer and the memory foam beneath. These two, combined with the tailored base layer, give it a good amount of sinkage.

If you favour softer mattresses, this may be a great option for you.

It comes with a 60-night comfort trial and a 5-year warranty. There’s free delivery and risk-free returns. It comes in four size options, from Single to Super King.

  • It feels extremely soft and inviting

Ghostbed – (Best For Heavy People)


The Ghostbed mattress is a great option for those of a bigger build or of a heavier weight. It combines memory foam with latex to give a blend of bounciness plus pressure relief.

It consists of three layers. The top layer is a quick-responding latex foam, which helps stop you feeling like you’re sinking too far into the mattress. The second layer is memory foam, which offers the sinkage and contouring which helps keep the spine healthy. The base layer of this option is a high-density poly-foam, which gives the item shape and durability.

The idea of putting the memory foam layer underneath a firmer, less responsive layer of foam latex is what makes this option particularly good for those of a heavier build. For heavier people, memory foam can offer too much sinkage, causing you to seem “trapped in the mattress.” By placing the foam a layer down, you can get all the spine-aligning and pressure-relieving benefits without the uncomfortable sinking feeling. It has a slightly bouncier feel, which also allows for more natural movement during the night. It can also be easier to get up from in the morning.

The Ghostbed comes in four sizes, from Single to UK King. It has excellent mattress reviews online, and comes with free delivery and returns. There is also an amazing 20-year warranty.

  • It allows those with a heavier build to experience the benefits of memory foam
  • This option is suitable for all sleeping positions thanks to the memory foam being at the second layer
  • The company offers an excellent 20-year warranty, twice as long as the standard 10
  • The latex and memory foam combination can cause this mattress to retain too much heat
  • It has no trial period
  • There is a potential for off-gassing

How To Choose The Best Mattress

There are a few different things to consider when shopping for a mattress. In the below buying guide, we’ll go into in-depth advice on what to look out for to help you find the perfect mattress for your needs.

  • Construction: You first want to consider whether you want a mattress consisting of foam, a mattress build around pocket springs, or a hybrid. There are benefits and drawbacks to both. Foam mattresses tend to offer more support and pressure relief, but very little bounce. Sprung mattresses tend to be, well, springier. A hybrid mattress can provide the best of both worlds, but make sure you get a good quality one.
  • Layers: Generally speaking, a mattress with more, different layers is more luxurious and offers better features. If every layer is doing a particular job, a mattress with five layers is doing two extra things than one with three. Make sure you read up on your chosen mattresses layers before purchase to make sure it suits your needs.
  • Firmness: The feel of a mattress (softness or hardness) can hugely affect your quality of sleep. Something which is medium to firm tends to be quite well-suited to the majority of people, although if you have more specialised needs that may not be the case for you.
  • Give: The amount of give your mattress has is another vital thing to consider. You don’t want to feel like you’re directly on top of the mattress, although nor do you want to feel like you’re trapped within it.
  • Motion Transfer: How much motion transfer your mattress offers is another aspect to consider. If you share a bed, you may want to have less bounce than if you sleep alone. Bounciness in a mattress tends to be a benefit during amorous activities, too.
  • Sleeping Position: The general rule of thumb is: if you sleep on your side, you want a softer mattress with more sinkage and pressure relief. If you sleep on your back, you want a firmer mattress with less sinkage and more bounce. If you’re a stomach sleeper, somewhere in the middle works best.
  • Bed Sharing: Bed sharing is something to consider regarding bounciness, and also concerning edge support. If you’re sharing a mattress with someone who takes up more space, edge support can be important to help you feel safe on your bed.
  • Personal Preference: All of the information in the world won’t help you pick the right mattress unless you also consider your own personal preferences. You must find your mattress comfortable, otherwise, you’ll be sacrificing the quality of your night’s sleep.
  • Budget: While investing in a high-end mattress can be money well spent, don’t go over your budget to buy a mattress. There are many fantastic, affordable mattresses on the market. Buying a mattress online in the UK is a great way to find a bargain.
  • Warranty: Although they can seem like the more boring aspect of new mattress shopping, do try to stay mindful of the warranty. Your future self may just end up thanking you.


While any of the options on our list would make fantastic choices as the “best mattress UK” category, we feel that the Simba Hybrid is our winner. The way it is constructed effectively helps with spine and joint health while its springs give an added bounce. It also comes in an excellent range of sizes from a Single to a Queen. But one of the most important reasons for choosing is that it offers the most universally comfortable sensation for any sleeping position.
