How to Choose a Mattress in 2026: 7-Step Expert Guide
Our recommendations are based on hands-on testing in 5 LA showrooms and feedback from 3,300+ verified customers.
This guide was written by our in-store Sleep Expert team with 20+ years of combined experience helping customers find the right mattress. Our recommendations are based on sleep science research, hands-on product testing, and thousands of in-store consultations.
Choosing a mattress comes down to four core factors: your sleep position, preferred mattress type, firmness level, and budget. Side sleepers generally do best on medium to medium-soft mattresses; back and stomach sleepers typically need something firmer. Memory foam excels at pressure relief, hybrids offer balanced support and bounce, and latex is a great natural option. Plan to spend at least 10–15 minutes lying on a mattress in-store before deciding — or take advantage of a generous home trial period if buying online.
01Key Takeaways
- Your sleep position is the single biggest factor in choosing the right firmness level.
- Mattress type (memory foam, hybrid, latex, innerspring) affects feel, motion isolation, and durability.
- Body weight matters — lighter sleepers often prefer softer mattresses; heavier sleepers typically need more support.
- A quality mattress in the $800–$1,500 range will serve most sleepers well for 8–10 years.
- Always check the return policy and sleep trial before purchasing — a good trial period is 90 days or more.
02Who This Guide Is For
This mattress buying guide is for anyone navigating that overwhelming moment of realizing their current mattress just isn't cutting it anymore. Whether you're replacing a 10-year-old spring mattress, buying your first bed as an adult, setting up a guest room, or trying to solve a specific problem like back pain or restless sleeping — this guide walks you through every decision, step by step. No jargon, no filler, just practical advice.
03Step 1: Start With Your Sleep Position
Before you think about brands, materials, or price tags, start here: how do you actually sleep? Your dominant sleep position is the most reliable predictor of which firmness level will keep your spine aligned and your pressure points comfortable through the night.
Side Sleepers
Side sleeping is the most common position — roughly 60% of adults default to it. When you sleep on your side, your shoulder and hip sink into the mattress while your waist needs support to keep your spine neutral. A mattress that's too firm will create painful pressure points at the shoulder and hip; one that's too soft won't support the waist.
Best firmness for side sleepers: Medium-soft to medium (4–6 on a 1–10 scale). Look for mattresses with a conforming comfort layer — memory foam and hybrid options tend to excel here. Our guide to the best mattresses for side sleepers goes deeper on this.
Back Sleepers
Back sleeping is great for spinal alignment — but only if your mattress supports the natural curve of your lower back. A mattress that sags under your hips will cause your lower back to dip out of alignment; one that's too firm won't allow your shoulders and hips to sink in slightly.
Best firmness for back sleepers: Medium to medium-firm (5–7). You want enough give to follow your body's contours but enough support to prevent that lower-back dip.
Stomach Sleepers
Stomach sleeping puts the most strain on your lower back and neck, because your midsection tends to sink, arching your spine unnaturally. A firmer mattress helps keep your body level and reduces that strain.
Best firmness for stomach sleepers: Firm to medium-firm (6–8). Avoid anything with a deep, plush comfort layer — it will cause your hips to sink too far.
Combination Sleepers
If you move around a lot throughout the night, you're a combination sleeper. The key here is responsiveness — you don't want to feel "stuck" in the mattress every time you shift positions.
Best firmness for combo sleepers: Medium (5–6), with a mattress that has good bounce and ease of movement. Hybrid mattresses are a popular choice for this group.
04Step 2: Choose Your Mattress Type
Once you know your firmness range, the next question is: what's the mattress actually made of? Each mattress type has a distinct feel, set of strengths, and trade-offs. Here's an honest breakdown.
| Type | Best For | Pros | Cons | Price Range |
|---|---|---|---|---|
| Memory Foam | Side sleepers, pressure relief, couples (motion isolation) | Excellent contouring, great motion isolation, quiet | Can sleep warm, slow response, heavier | $400–$1,500+ |
| Hybrid | Most sleepers, combination sleepers | Balanced support + cushion, good airflow, responsive | Heavier, more expensive than all-foam | $700–$2,500+ |
| Latex | Natural/organic preference, durability, bounce | Natural material option, durable, breathable, responsive | Heavy, expensive, firm feel can be polarizing | $1,000–$3,000+ |
| Innerspring | Stomach sleepers, traditional feel lovers, hot sleepers | Excellent airflow, bouncy, affordable options | Less pressure relief, more motion transfer | $300–$1,200+ |
Memory Foam
Memory foam mattresses are known for their pressure-relieving "hug" — the material slowly conforms to your body shape and distributes weight evenly. This makes them especially popular with side sleepers and anyone dealing with joint or pressure-point pain. The trade-off is that traditional memory foam can trap heat, though most modern versions include gel infusions or open-cell technology to improve airflow. Memory foam also has slow response time, meaning it takes a moment to spring back when you move — some people love this, others find it makes repositioning feel like work.
Hybrid
Hybrid mattresses combine a pocketed coil support system with foam or latex comfort layers on top. The result is a mattress that offers the contouring of foam with the support, bounce, and breathability of coils. Most sleepers — regardless of position — do well on a quality hybrid. They're particularly good for combination sleepers and couples with different preferences. Our deeper comparison of memory foam vs. hybrid mattresses can help if you're on the fence between the two.
Latex
Latex mattresses are made from natural or synthetic rubber. Natural latex — derived from rubber trees — is a popular choice for those seeking an organic or eco-conscious option. Latex is durable (often lasting 12–15 years), naturally breathable, and has a distinct responsive feel that's bouncier than memory foam but more cushioning than innerspring. If you want something natural and long-lasting, latex is worth the premium price.
Innerspring
Traditional innerspring mattresses use a coil support system with a thin comfort layer on top. They're the most breathable type, sleep cool, and have a classic bouncy feel. Modern innerspring options have improved significantly with individually wrapped (pocketed) coils that reduce motion transfer. They tend to be more affordable and are a solid choice for stomach sleepers or anyone who prefers a firmer, more traditional feel.
05Step 3: Pick the Right Firmness Level
Firmness is rated on a scale from 1 (softest) to 10 (firmest), though most mattresses on the market fall between 3 and 8. Understanding this scale — and where you likely fall on it — is essential to making a good decision.
- Soft (2–3): Plush, deep sink, best for lighter side sleepers
- Medium-Soft (4): Contouring with gentle support, great for side sleepers
- Medium (5): Most versatile, works for a wide range of sleepers
- Medium-Firm (6–7): Popular with back and combination sleepers
- Firm (7–8): Minimal sink, best for stomach sleepers and heavier back sleepers
- Extra Firm (9–10): Very little give, rarely needed except for specific medical reasons
A more detailed breakdown — including what firmness to choose based on your body weight and sleep position — is available in our complete mattress firmness guide.

06Step 4: Consider Your Body Type and Weight
Body weight significantly affects how a mattress feels — and this is one of the most underappreciated factors in mattress shopping. The same mattress can feel completely different to a 130-pound person versus a 230-pound person because your weight determines how deeply you compress the comfort layers.
Lighter Sleepers (Under 130 lbs)
Lighter sleepers don't compress mattress materials as deeply, meaning a mattress that feels medium to most people may feel firm to them. If you're on the lighter side, lean toward softer options than the general recommendation for your sleep position — and pay close attention to comfort layer thickness and density.
Average-Weight Sleepers (130–230 lbs)
Most mattress firmness ratings are calibrated for this range. General recommendations based on sleep position apply reliably here.
Heavier Sleepers (Over 230 lbs)
Heavier sleepers compress mattresses more deeply, which can make a "medium" mattress feel soft, and a "soft" mattress feel like it has no support at all. Look for mattresses with denser foam (5+ lb/ft³ for memory foam) or thicker coil gauges, and consider going one firmness level firmer than your sleep position alone would suggest. Also look for mattresses with reinforced edge support — this extends the usable sleep surface and makes getting in and out of bed easier.
Couples With Different Preferences
This is one of the trickier scenarios. If you and your partner have significantly different firmness preferences or sleep positions, look for: (a) a hybrid with good motion isolation so different layers don't affect each other, (b) a mattress with dual firmness options, or (c) two separate twin XL mattresses in a split king configuration — especially useful with an adjustable base. Our adjustable bed collection is worth exploring if this applies to you.
07Step 5: Set a Realistic Budget
Mattress prices range from under $200 (roll-packed budget options) to over $5,000 (luxury hand-crafted beds). Here's how to think about what you actually need to spend to sleep well.
Budget Tier: Under $500
You can find decent mattresses in this range — mostly all-foam or basic innerspring. These are fine for guest rooms or temporary situations. Expect a lifespan of 4–6 years and fewer options for customization.
Mid-Range: $500–$1,500
This is the sweet spot for most shoppers. You'll find quality memory foam, solid hybrid mattresses, and some latex options in this range. Most major brands offer good construction, meaningful comfort layers, and warranties of 10 years or more. This range is where value-to-quality peaks for most people.
Premium: $1,500–$3,000+
At this level, you're paying for higher-quality materials (natural latex, organic components, hand-tufted covers), better durability, and often more specialized construction. If you have specific needs — organic materials, heavy-duty support, or a very specific feel — this tier is where to look.
What Actually Determines Price
The cost of a mattress is driven by: material quality (natural latex and organic materials cost more), layer thickness and density, coil count and gauge (for hybrids/innerspring), craftsmanship, and brand overhead. Be skeptical of very high markups without clear material justification — and equally skeptical of very cheap prices without understanding why.
Pro tip: A mattress is an investment in roughly 2,500 hours of sleep per year. Divided over an 8-year lifespan, even a $1,200 mattress costs about 6 cents per night.
08Step 6: Test In Person vs. Buy Online
The rise of bed-in-a-box brands has made it easy to buy a mattress online — but "easy" doesn't always mean "right." Here's how to think about both options honestly.
Testing In Person
There's no substitute for lying on a mattress. When you test in-store, lie in your actual sleep position for at least 10–15 minutes (not just 30 seconds). Bring your partner if you share a bed. Test mattresses back-to-back using the same pillow height you'd use at home. Pay attention to pressure points at your shoulder, hip, and lower back — not just the general "feel."
The best way to know if a mattress is right for you is to lie on it — really lie on it, in your sleep position, for at least 10–15 minutes. Visit one of our Los Angeles area showrooms and take your time. Our sleep consultants are there to help, not to rush you. No pressure, ever.
Buying Online
Online mattress brands often offer competitive pricing (lower overhead = lower prices) and the convenience of delivery to your door. The key is to only buy online from brands with a robust home trial — 100 nights minimum, free returns, no restocking fees. If a company makes it difficult to return a mattress you don't love, that's a red flag.
One practical approach: test mattress types and firmness levels in person to understand what you like, then decide whether to buy in-store or online. Many people discover that they prefer a feel they wouldn't have predicted — in-store testing can save you from a costly mistake.
09Step 7: Check the Return Policy and Sleep Trial
Before you commit to any mattress purchase, read the fine print on the return policy. This step is especially important for online purchases but matters for in-store buys too.
What to Look For
- Trial length: 90 nights is a reasonable minimum; 120–365 nights is better. Your body needs time to adjust to a new mattress, and initial impressions aren't always accurate.
- Free returns: Returns should be free. If there's a pickup or restocking fee, factor that into your total cost.
- Full refund vs. store credit: Understand whether a return gets you your money back or only store credit.
- Condition requirements: Most companies require the mattress to be undamaged and used with a mattress protector. Some won't accept returns if the mattress has stains.
- Warranty: A quality mattress should come with at least a 10-year warranty. Read what's actually covered — most warranties cover manufacturing defects and significant sagging (typically 1–1.5 inches or more), not normal wear.
10Common Mistakes When Buying a Mattress
Even well-intentioned shoppers make these errors. Here's what to avoid:
1. Deciding in 60 Seconds
Sitting on the edge of a mattress for a minute tells you almost nothing. Lie down. Get in your actual sleep position. Stay for at least 10 minutes. The mattress that feels "fine" standing up might feel very different once you're horizontal and your body weight distributes differently.
2. Shopping by Brand Alone
Brand recognition doesn't guarantee a good fit for your specific body and sleep style. Focus on construction, materials, and how it feels — not the logo on the tag.
3. Ignoring Your Sleep Position
Many shoppers pick firmness based on a vague sense of "I like firm beds" without connecting it to how they actually sleep. If you're a side sleeper who buys a firm mattress because it "feels sturdy," you're going to wake up with sore shoulders and hips.
4. Forgetting About the Foundation
A great mattress on a worn-out or wrong-type foundation will perform poorly and may void your warranty. Make sure your base or bed frame is compatible with your mattress type. Memory foam and latex mattresses need solid or slatted support (slats no more than 3 inches apart); traditional innerspring can work on box springs.
5. Not Considering Motion Transfer (for Couples)
If you share a bed, motion isolation matters. Individually wrapped coil hybrids and memory foam mattresses significantly reduce the ripple effect when one partner moves. An innerspring mattress with a continuous coil system is the worst offender for motion transfer.
6. Skipping the Mattress Protector
A mattress protector isn't optional — it's essential. Most warranties are voided if the mattress has stains, and a good protector extends the life of your mattress by years. Get one at the same time you buy your mattress.
7. Buying the Wrong Size
A queen mattress feels very different for one person versus two. A full-size mattress is only 54 inches wide — barely enough for two adults to sleep comfortably. Our mattress size guide covers all dimensions and helps you match size to your room and sleeping situation.
If you're specifically dealing with back pain, our guide to the best mattresses for back pain addresses the specific considerations for that common concern.
11Frequently Asked Questions
How long should a mattress last?
Most quality mattresses are designed to last 8–10 years with regular use. Latex mattresses can last 12–15 years or longer. Factors that shorten mattress life include heavier use, sleeping without a protector, improper foundation, and lower-quality foam density. If your mattress is sagging noticeably, causing pain you didn't have before, or you wake up feeling worse than when you went to bed, it's time to replace it — regardless of age.
What's the difference between a hybrid and a memory foam mattress?
A memory foam mattress is made entirely of foam layers — typically a dense support foam base with softer memory foam on top. A hybrid mattress uses a pocketed coil system as its support core, with foam or latex comfort layers on top. Hybrids are generally more breathable, more responsive (easier to move on), and better for edge support. Memory foam offers superior motion isolation and a more enveloping feel. Neither is objectively better — it depends on what you value most. For a full side-by-side, see our memory foam vs. hybrid comparison.
Is a firm mattress better for back pain?
Not necessarily — and this is a common misconception. The research on mattress firmness and back pain suggests that a medium-firm mattress tends to produce the best outcomes for most people with lower back pain. A mattress that's too firm can create pressure points and push the spine out of alignment just as much as one that's too soft. The goal is neutral spinal alignment, which depends on your sleep position and body type, not just firmness level. Our back pain mattress guide covers this topic in full.
Can I try a mattress before I buy it?
Yes — and you should. In-store testing lets you compare multiple mattresses side by side and experience the actual feel rather than relying on descriptions alone. Spending 10–15 minutes lying in your actual sleep position gives you much more useful information than any review or spec sheet. If you're buying online, look for brands with free home trial periods of at least 90 nights so you can test it in your own sleep environment before committing.
What mattress is best for hot sleepers?
Hot sleepers generally do best with mattresses that promote airflow rather than trap heat. Innerspring and hybrid mattresses with coil systems allow air to circulate throughout the mattress core. Latex is naturally breathable and a good option. If you prefer the feel of memory foam but sleep warm, look for gel-infused or copper-infused memory foam, or models with perforated foam layers. Avoid dense all-foam mattresses without any cooling technology if heat retention is a major concern for you.
How much should I spend on a mattress?
For most people, a quality mattress in the $800–$1,500 range delivers excellent value and durability. You can find good options below this range, but material quality and longevity tend to drop. Going above $1,500 starts to bring in premium materials like natural latex and organic fabrics — worth it if those are priorities, but not necessary for a great night's sleep. The key is understanding what you're paying for, not just chasing a high price tag or hunting for the lowest one.
Do I need a special bed frame or foundation for my new mattress?
It depends on the mattress type. Memory foam and latex mattresses need solid or closely slatted support (slats no more than 3 inches apart) to prevent sagging and maintain warranty coverage — they should not be placed on a traditional box spring. Hybrid and innerspring mattresses are more flexible and can work on box springs, platform bases, or adjustable bases. Always check the manufacturer's recommendations before buying a foundation, and confirm your existing bed frame can support the mattress weight — especially important for heavier hybrid and latex models.
Is an organic mattress worth it?
Organic mattresses — made with certified organic latex, wool, and cotton — appeal to people who want to minimize exposure to synthetic chemicals and support more sustainable sourcing. They tend to be durable, naturally breathable, and free of certain fire-retardant chemicals used in conventional mattresses. They do come at a significant price premium. Whether it's "worth it" depends on your personal priorities and sensitivities. If you have chemical sensitivities, allergies, or a strong preference for natural materials, exploring our organic mattress collection is a good starting point.
