1. Consider Your Sleep Position

Depending on the sleep position you prefer, different types of mattresses and firmness levels may feel more comfortable and supportive. Consider your unique preferences as well as the features of each mattress to ensure you know how to pick a mattress that will best support your spine and relieve pressure where you need the most comfort.

Side Sleepers

Touches de couchage latérales lie on the left or right side of their body while sleeping. Side sleeper mattresses may be softer and more contouring compared to a firmer mattress that a back or stomach sleeper might prefer. A good mattress for side sleepers helps keep the head, shoulders, and back aligned while cushioning the shoulders and hips.

Back Sleepers

Dormeurs arrière sleep primarily on their backs, either with their arms straight or above their heads. This sleeping position is considered one of the best for spinal alignment and good sleep posture. The best mattresses for back sleepers are typically medium-firm, offering ample spinal support with zoned pressure relief for the hips and back.

Stomach Sleepers

A somnolence de l'estomac is someone who sleeps on their chest and stomach, which can result in poor spinal alignment and back arching without sufficient support.

If you sleep on your stomach, you need a mattress that is medium-firm to firm to keep your body from sagging into the mattress. This firmness range also supports your body and gives gentle pressure relief.

Combination Sleepers

Combination sleepers may switch positions as they sleep. These individuals need a responsive mattress with plenty of support to align the spine and relieve body pain.

Medium to medium-firm mattresses are a great compromise for a variety of sleep positions, firm enough to align your spine and soft enough to ease pressure on your joints, making mattresses in this firmness range great for combination sleepers.

2. Choose a Mattress Type

As you shop for a new mattress, you’ll find a variety of types de matelas to consider, from traditional memory foam to the innovative GelFlex® Grid. When weighing your options, remember that the best fit for your needs depends on several factors, such as price range, comfort needs, sleeping position, and breathability.

If you're overwhelmed by the wide range of mattress types on the market, here's a quick guide to the most common types of mattresses available.

GelFlex® Grille 

Purple mattresses feature the innovative GelFlex® Grille, our proprietary sleep technology that instantly adapts to your body as you move, providing tailored pressure relief and support without trapping heat.

Purple is the only company in the world that uses the GelFlex® Grid, enhancing your sleep quality with unparalleled responsiveness, temperature balancing, durability, and comfort.

Mousse

Memory foam mattresses feature a soft, dense layer that conforms to your body shape for a cradling sensation. Memory foam is made out of polyurethane and comes primarily in three different types: traditional, gel-infused, and open cell.

• Mousse de mémoire traditionnelle: While it helps preserve your spine's natural curvature, hot sleepers dislike it because of its heat retention.
• Gel memory foam: Gel-infused memory foam blends memory foam with gel microbeads, providing a cooler mattress that helps regulate body temperature better than traditional memory foam.
• Open cell memory foam: Open cell foam is a more breathable version of memory foam, with pockets for more airflow to keep you cool.
• Other foams: Purple mattresses feature different types of high-quality polyurethane foam with the GelFlex® Grid for added pressure relief and comfort.

Printemps intérieur

A traditional innerspring mattress has a coil construction for its base layer topped with a layer of memory foam or latex for extra comfort. 

The coil systems make this mattress type more responsive at a lower price, but innerspring mattresses may not provide as much pressure relief or motion isolation as other mattress types.

Hybride

A hybrid mattress is a multi-layer mattress made with a combination of innerspring steel coils and comfort layers featuring memory foam, latex, or the GelFlex® Grid for a supportive, responsive sleeping surface that provides deep pressure relief.

Hybrid mattresses like Purple’s RestorePlus™ Hybrid offer support for high-pressure areas like the neck and lower back, easing body pain and promoting restful sleep. Combined with extra comfort layers, hybrid mattresses are popular for a variety of sleepers.

Latex

A latex mattress can be made with natural or synthetic latex, and this type is known for having better airflow than traditional memory foam. This soft, denser foam hugs the body's natural curves and provides gentle pressure relief.

Natural latex can be more expensive than synthetic latex or memory foam, but it is a good choice for shoppers looking for a cooling, supportive mattress.

Air

You can inflate or deflate an air mattress to your preferred firmness to customize your sleep experience. Air mattresses are not typically used as primary beds, as they are relatively inexpensive, may deflate easily, and are less durable than standard mattresses.

Airbeds like those from Nombre de sommeil offer further customization with more structure and comfort layers than a typical air mattress, which often appeals to couples with different sleep preferences. These options require manual adjustment and tend to come with a higher price tag.

3. Pick Your Firmness

Mattress manufacturers typically rank la fermeté de la matrice on a scale of 1 to 10, with 1 as the softest and 10 as the firmest.

Soft and firm mattresses offer different levels of comfort and support; softer mattresses can cradle pressure points to relieve pain, but firmer mattresses provide more support for spinal alignment to reduce discomfort.

Here's a quick breakdown of different mattress firmness levels and which levels may be best suited for your preferred sleeping position. Of course, the firmness you choose depends on what feels best for you, so consider your unique needs before making a decision.

The most popular firmness levels are medium and medium-firm, offering a balance of comfort and support that accommodates most sleep positions. A medium-firm mattress helps keep the spine in proper alignment and allows just enough sinkage to ease pressure from the hips, shoulders, and back.

On the extreme ends of the firmness scale, soft and firm mattresses may not be suitable for all sleepers. Soft and extra soft mattresses may allow too much sinkage, especially for heavier individuals, which can put added pressure on your joints and cause pain.

If possible, it’s best to try mattresses with different firmness levels to determine what is most comfortable and supportive for your needs. You can visit a mattress store in your area to test what feels best.

4. Select a Mattress Size and Thickness

Les mattress size you choose largely depends on the amount of space you have available as well as how much room you need when you sleep. 

Not sure  quelle taille de lit vous devriez obtenir ? Consider the dimensions of each standard bed size to inform your choice.

You should also consider the number of sleepers, your height, and room dimensions when choosing a mattress size. The best bed size for couples, for example, is typically a queen or larger, but your needs and preferences may vary.

Jumeau

Twin beds are the smallest standard size on the market, best suited for sleepers under 6’ who don’t need a lot of space.

Jumeau XL

Commonly found in college dorms, twin XL beds offer more legroom for young adults or single sleepers under 6’5”.

Complet

Full beds can accommodate two sleepers, but they may be better suited for individuals who like to spread out.

Reine

Queen beds are the most popular mattress size, offering more space than a full without crowding the bedroom.

Californie Roi

The longest standard mattress size but with a smaller surface area than kings, California kings are great for couples who need extra legroom.

Roi

Also known as an Eastern king, king beds are the largest standard mattress size, offering plenty of space for couples to sprawl.

In addition to the size of your mattress, consider épaisseur de la matrice before making a purchase. 

Thicker mattresses are not inherently superior, but thinner or lower-profile mattresses may not offer enough pressure relief or support, especially for sleepers with a heavier bodyweight.

Rather than make a judgment based solely on the depth of a mattress, consider the quality and features of the mattress’s layers, assessing how the mattress comes together to keep you comfortable while you rest. Make sure you choose a bed frame that is compatible with your mattress and room size, as well.

5. Assess Your Body Type

Your height and weight should also play a part in your mattress selection.

Individuals over 6 feet should opt for a queen size bed or larger to ensure they have enough legroom. If you have a wider frame, make sure you choose a mattress that is wide enough for you to sleep comfortably without feeling cramped.

Lightweight individuals may benefit from a softer mattress since they won’t sink in as much, but you may prefer a firmer mattress if you need better support for spinal alignment or you sleep on your stomach.

Heavier individuals often choose firmer, thicker mattresses to provide the spinal alignment and comfort they need, as they may sink too much on a softer mattress, increasing pressure on sensitive areas like the hips and shoulders. 

Make sure you consider the mattress weight limit so you can rest without worrying about premature sagging and insufficient support.

Regardless of your height and weight, look for a mattress that supports proper spinal alignment and provides sufficient pressure relief for your needs. 

6. Address Your Sleep Concerns

Your level of comfort directly affects how well you sleep, and localized pain and your sleeping temperature can affect your sleep quality. If you  ne peut pas se mettre à l'aise dans le lit, you may have trouble falling or staying asleep, which can negatively impact your mental and physical health.¹

Consider any existing sleep concerns you have when choosing a new mattress to give yourself the best possible sleep quality.

Température

If you’ve ever woken up sweating or shivering, you understand how important finding the best temperature for sleep is. Maintaining a comfortable temperature while you’re asleep can help you stay asleep longer and get higher-quality rest each night.

Some people are prone to sweating at night while others may feel chilly even on a warm evening. 

Des dormants chauds often need a mattress with good airflow to draw heat away from their skin and avoid overheating.

If you tend to sleep hot, you can also use cooling bed sheets, like the Purple SoftStretch® Sheets, for better temperature regulation with moisture-wicking material to keep you cool and comfortable.

Cold sleepers struggle to stay warm while asleep, resulting in disruptions and poor sleep quality. People who have this sleep concern are most comfortable on mattresses that absorb and retain body heat, such as traditional memory foam.

If you sleep cold, you can also try wearing socks to bed, using warmer sheets, or adding a cozy top layer to stay warm, especially if you don’t like the feel of memory foam.

Body Pain

Some people suffer from back pain because of medical conditions, poor posture, and injuries. Trying to sleep with body pain often means struggling to find a comfortable position, waking up throughout the night, and starting your day feeling tired and sore. Depending on the type, cause, and severity of your symptoms, finding the best mattress for body pain can offer relief and help improve your sleep quality.

Mattresses that contour around the body's natural shape can help with non-specific back pain issues and cradle your pressure points.

One study suggests that medium-firm mattresses may offer more relief for individuals with non-specific lower back pain, promoting higher-quality sleep and fewer sleep disruptions.²

You can also try changing your sleep position or cushioning areas of your body with pillows to alleviate pressure.

For example, back sleepers with back pain can put a pillow under their knees to take pressure off their lower spine, and side sleepers can try sleeping with a pillow between their knees to reduce pain in the hips and back.

You may also experience back pain from a new mattress as you break it in, though this discomfort should go away after a few weeks. If pain continues disrupting your sleep or you have any questions about potential causes and alternative solutions, talk to your doctor.

7. Set Your Budget

Before choosing a mattress, set a maximum budget that will accommodate your desired mattress type, size, and features.

Some mattresses are more expensive because they use premium materials, have high-quality construction, or are simply a larger size.

Higher prices don’t always mean higher quality, so it’s important to evaluate the mattress based on additional factors like unique features and customer reviews.

How much can you expect to spend on a mattress? For the most part, mattresses can cost anywhere between €600 and €9,000, but what you spend on a mattress depends on the features, size, type, brand, and quality you choose.

If you are looking for the best affordable mattress, The PurpleFlex™Mattress is a great option, featuring the instantly adaptive GelFlex Grid® at a price you'll love.

Remember that your mattress is an investment, so you should look for one that will be comfortable and supportive for as long as possible.

8. Decide If You’re Shopping Online vs. In-Store

When deciding what mattress you want, it’s important to consider where you plan to do your shopping: online or in-store.

When you buy a mattress online, you can take advantage of benefits like free shipping, competitive sleep trials, generous return policies, and unbeatable sales and discounts.

The biggest consideration for shopping online is that you don’t have the option to try before you buy. There are a few ways to sidestep this obstacle, such as trying out the mattress you want in a physical retailer before placing an online order. 

You can also look through customer reviews online to get a sense of the best features and any common concerns.

Purple also offers a miniature GelFlex® Grid sample at a low cost so you can actually feel the proprietary sleep technology in your hands before trying one of our mattresses.

9. Choose Delivery or Pickup

Depending on where you shop for a mattress, you may have limited options for how to get it home.

When choosing the mattress you want, consider your delivery or pickup options first. Online sellers often offer free delivery, and some provide setup services to ensure you can rest easily. Some online mattress companies will even get rid of your old mattress, freeing up your space to make it easier to set up your new bedroom.

Brick-and-mortar stores may not have the same options, so you may have to arrange transportation to pick up and move your new mattress or pay an additional fee for delivery.

Consider costs and convenience when deciding where to buy your mattress and how to get it where you need it.

10. Compare Policies: Returns, Warranties, and Trials

While you should primarily choose a mattress based on how well it will meet your sleep needs, it’s often a good idea to compare return, sleep trial, and warranty policies before making a purchase. When comparing policies, look for:

Sleep Trials	Retourne	Garanties
How many nights can you sleep on your mattress and still be able to return it? Sleep trials often range from 100 to 365 nights, giving you plenty of time to test your mattress.	What is the minimum length of time before you’re eligible to return the mattress? Does the company cover return shipping costs, or will you have to pay out of pocket?	What kind of damage does the warranty cover? When does the warranty expire? Are there any restrictions or requirements that affect whether the warranty applies?

These policies are especially important if you’re buying online. Since you likely won’t know how a new mattress will feel if you aren’t able to test it beforehand, a generous sleep trial and  politique de retour can give you peace of mind.

11. Shop at the Best Time To Buy

Online mattress companies often offer sales and discounts, so you’ll rarely pay full market price for a mattress online. If you aren’t in a rush to buy a new mattress, you can wait for the mattress you want to go on sale.

Les meilleur moment pour acheter un matelas is during key shopping holidays when mattress companies are more likely to run competitive sales. You’ll usually find the best deals around:
