How to find out What-Mattress is best for you?

Being well-rested is scientifically proven to boost your energy levels, combat stress, accelerate injury recovery, and help reduce risks of illness. However, we do so much more than just sleep on a mattress; it’s the centre-piece of whatever room it’s in, lending itself as not only a bed but a sofa to relax on, a bench to get changed on, a place of love, and even a ‘temporary’ laundry depository.

The biggest difficulty you’ll likely face when buying a mattress these days is navigating the seemingly infinite number of brands vying for your attention. We understand how difficult it can be to choose a mattress in this confusing and clustered market, with so many different models, tech, jargon and deals – so this guide should hopefully provide some much needed clarity to help you pick a mattress that’s best for your individual requirements.

Here are some things you need to consider:

Mattress Type

Memory foam mattresses are by far the most common mattress type you’ll find on the market today. They typically comprise of several layers of foam that get increasingly dense towards the base and often are infused with cooling technology to prevent overheating. Top layers are light & fluffy so you sleep on a surface that contours around your pressure points, resulting in a cushioned cradling of the body. Middle layers tend to be slightly more responsive, making it easier to move around and change position. They are frequently known as ‘transition’ layers as they act as a buffer between the top layer and the high-density base layer, which is designed to provide support and prevent sinkage.

Fun fact: The technical term for memory foam is ‘viscoelastic foam’ due to its viscous & elastic properties and it was first developed by NASA in 1966 to improve the safety of aircraft cushions.

Hybrid mattresses layer foam comfort surfaces atop a bed of coils in order to provide a more supportive experience whilst allowing air to flow through the mattress, which helps dissipate heat and keep the body cool. The term ‘hybrid’ comes from the combination of materials & design features found in other mattress types, and it’s widely suggested that they offer the best of both worlds. Because of the materials used and the more complex construction, you can expect to pay more for a hybrid variant than an all-foam mattress.

Consider Memory Foam if you:

  • Need deep contouring and cradling
  • Disturb easily by your partner’s movement
  • Have sharp pressure points in need of high pressure-relief
  • Are on more of a budget

Consider Hybrid if you:

  • Enjoy the bouncy feel of a coil-based mattress
  • Are in need of moderate pressure relief
  • Reside on the heavier side of the scales (100kg+)
  • Sleep hot and need a high degree of cooling

Sleeping Position

Now here’s something you may not have given much thought about, but how you sleep is a critical factor in determining what-mattress you should sleep on.

Stomach-sleepers tend to suffer from strain on the neck & spine and will benefit from a supportive mattress that prevents the midsection from sinking in too deeply, thereby helping to align the spine and reduce back pain.

Side-sleepers will benefit from a mattress that contours to the body shape and provides decent pressure-point relief, particularly in the shoulder and hip areas. Being the most popular sleeping position, the good news is that there’s plenty of great options to pick from.

Back-sleepers should consider that proper spine alignment is probably the most important factor. A level surface with some conforming but no sagging is usually the best option as the mattress must provide support to the hips & shoulders without applying too much pressure.

Combo-sleepers are those who switch it up throughout the night as they nestle from one orientation to another. As such, a mattress with high responsivity will help with ease of movement and prevent that stuck-in feeling commonly referred to as the ‘quicksand’ effect. These sleepers should also consider an option with good edge support so that they aren’t at risk of rolling off the side of the bed during the night.

Firmness Level

Quantifying something as subjective as ‘feel’ is obviously not an exact science but manufacturers will often indicate the firmness of their mattresses by using a simple scale from 1 – 10, where 1 is like sleeping on air and 10 is like sleeping on a rock.

Factors that determine the firmness of a particular mattress include things such as weight, height, general body-shape, touch-sensitivity, and sleeping position. For example, a heavier individual who exerts more pressure into the mattress, thereby allowing the foams & coils to react, may consider their experience to be soft – whereas a lighter person may call it firm as the same layers respond to their body differently. Differences in how sensitive you are to touch could mean that identical twins could each have a unique impression as to how firm or soft a mattress feels.

Materials Used

The materials being used in today’s mattresses are surprisingly sophisticated and you may be impressed with just how much technology is engineered into delivering the perfect sleeping experience. The truth is that a lot of brands are using different jargon to present the same solution so it’s wise to look past the pretentious terminology and pay attention to what is actually being achieved, how practical it is, and whether it applies to your needs.

Organic materials may be of interest to those more eco-conscious consumers out there, as sustainability becomes increasingly important in the welfare of our planet. Materials such as ‘latex’ are a naturally farmed alternative to factory produced foams & coils and can provide an equally durable mattress construction, so you can rest assured without the guilt of contributing towards a polluting system. However, organic materials & sustainability don’t always go hand-in-hand, so be sure to check for the appropriate certifications or other such industry recognized stamps of approval.

Water resistant mattress covers or top layers are another key selling point you may want to look out for, as spillages of your water, morning tea or coffee could otherwise soak into your mattress permanently, instead of beading off. Machine-washable covers are a life-saver for when an accidental spillage occurs as they save you from having to spot-clean, which in and of itself can lead to further water stains that only worsen the problem.

Chemicals are abundant in most non-organic mattresses and are used for purposes such as cooling. There’s no need to fear though, as long as the mattress carries industry recognized certifications to prove they meet the highest standards of consumer health & safety, you can take confidence that your place of rest is benefitting your wellbeing, not damaging it.

Temperature Control

There’s arguably nothing worse than tossing & turning throughout the night due to overheating. The British summer is becoming increasingly unbearable without adequate air-conditioning and the ability to have a comfortable night’s sleep is seriously jeopardized, especially for those who feel vulnerable without their covers on. Don’t sweat it; mattresses these days have implemented countless different methods to extract heat away from the body and out of the mattress, which aim to either achieve temperature-neutrality or active cooling to the sleeper.

Motion Isolation

If you’re sensitive to movements and sleep with a partner who tends to roll around during the night, or even if they regularly get up to go to the bathroom, then selecting a mattress that minimizes motion-transfer could be a priority for you. All-foam mattresses tend to score higher in this field, particularly if they land towards the softer side of the firmness spectrum – however, there are also plenty of hybrid variants that excel on this front as well thanks to the use of individually wrapped coils & purpose-built comfort layering.

Budget

On average you spend a third of your life sleeping, so having the perfect mattress for your unique needs is perhaps one of the most worthwhile investments you can make into your overall wellbeing. As a mattress is a purchase made only every 10-15+ years, it is highly advisable to avoid comfort sacrifices just to save a few quid. The damage to your overall health in the long-term is far more detrimental than the immediate impact to your wallet, and even that is largely minimized thanks to the regular deals & attractive financing options that most brands offer.

Prices range significantly depending on what mattress construction, size, and materials you desire. Since prices frequently fluctuate, you can hit the ‘check price’ button to be delivered straight to the foremost accurate source for pricing information, the brand’s own product page. 

Financing options are commonly available to breakdown the upfront costs into more easily manageable periodic instalments. 

Free trial periods are a great way to test out whether you have made the right choice with your mattress purchase. These trials can range all the way up to a year and alleviate the risks of spending a lot of money on something you haven’t actually tried yet.

Warranties provide you with the further peace of mind that your money has been well-spent. Most mattress brands offer very compelling warranty assurances such as full-refunds or replacement items in the event that something has gone wrong.
