How to Choose a Mattress in 8 Steps

Here is how to choose a mattress without the guesswork: start with how you sleep and how much you weigh, because those two facts set your ideal firmness. Then pick a mattress type that fits your priorities (cooling, motion isolation, bounce), set a realistic budget, and buy only from a company with a trial and return policy you'd actually use.

That's the whole framework. The rest of this guide walks through each step in order, with a decision table at the end that turns your answers into a short list. Most shoppers can narrow 25 options down to two or three in about ten minutes.

If you'd rather skip the reading, our quiz runs the same logic for you and matches you to specific mattresses across brands.

The quick answer: what matters most when choosing a mattress

Not every factor carries equal weight. In rough order of importance:

1. Sleep position and body weight decide firmness, and firmness decides comfort.
2. Mattress type (memory foam, hybrid, latex, innerspring) decides the feel: hug versus bounce, warm versus breathable.
3. Special needs such as sleeping hot, sharing the bed, or back pain narrow the field further.
4. Budget and policies decide which of your finalists is worth the risk.

Get the first two right and you've avoided the most common mistake: buying a mattress that's simply the wrong firmness for your body.

Step 1: Start with your sleep position

Your main sleep position is the single best predictor of what will feel good. Think about how you wake up, not how you fall asleep.

• Side sleepers put their weight on the shoulder and hip. They usually need a softer surface that lets those points sink in so the spine stays level. Too firm, and you wake with a sore shoulder or numb arm. See our best mattress for side sleepers picks.
• Back sleepers need the lower back supported so it doesn't sag. Medium-firm is the usual sweet spot: enough give for the shoulders, enough support under the lumbar curve. Start with our best mattress for back sleepers list.
• Stomach sleepers need the firmest support, because a soft mattress lets the hips sink and bends the lower back. Our best mattress for stomach sleepers guide focuses on firm, flatter surfaces.
• Combination sleepers change positions through the night. You'll want a medium to medium-firm mattress with some bounce so turning over takes less effort. Hybrids and latex usually fit better than slow-moving memory foam.

Step 2: Factor in your body weight

The same mattress feels different to a 120-pound person and a 260-pound person. Heavier bodies sink further, so a mattress feels softer to them. Lighter bodies barely compress the top layers, so it feels firmer.

A simple rule of thumb:

• Under about 130 pounds: go about one step softer than the usual advice for your position.
• About 130 to 230 pounds: the standard advice applies.
• Over about 230 pounds: go about one step firmer, and favor thicker mattresses with coils and strong edges. Our best mattress for heavy people list is built around durability and edge support.

Step 3: Choose your firmness level

Firmness is usually described on a 1-10 scale, where 1 is extremely soft and 10 is extremely firm. Most mattresses sold online land between 5 and 8.

Putting steps 1 and 2 together gives you a target range:

• Side sleepers: about 4-6 (medium-soft to medium)
• Back sleepers: about 5.5-7 (medium to medium-firm)
• Stomach sleepers: about 6.5-8 (medium-firm to firm)
• Combination sleepers: about 5.5-7

Adjust by about one point for body weight as described above. One caution: firmness labels aren't standardized. The Siena Memory Foam is sold as medium-firm, but independent testers rate it about 8 out of 10, which is firm. Use independent ratings when you can. Our mattress firmness scale guide has the full position-by-weight chart, and if you know you want a firm feel, start with the best firm mattress list.

Step 4: Pick a mattress type

There are four main types, plus a few niche ones. Each has a clear personality.

Memory foam: contouring and quiet

All-foam mattresses hug your body, absorb motion and cost the least on average. The trade-offs: less bounce, weaker edges, and some models trap heat. In the 11 all-foam mattresses we track, the average motion isolation rating is about 4.6 out of 5, but the average bounce is just 2.4. Browse the best memory foam mattress picks.

Hybrid: coils plus comfort layers

A hybrid puts foam or latex comfort layers over a pocketed-coil support core. You get more bounce, better airflow and firmer edges than all-foam, usually at a higher price. Across the nine hybrids we track, edge support averages about 4.3 out of 5 versus 3.5 for all-foam. See the best hybrid mattress list, or read hybrid vs memory foam for a deeper comparison.

Latex and latex hybrid: buoyant and long-lasting

Latex is springy and responsive, sleeps cooler than most foam, and tends to last a long time. Natural and organic latex models such as the Avocado Green and Birch Natural appeal to eco-minded shoppers. The trade-offs: higher prices and a heavier mattress.

Innerspring: classic bounce

Traditional coil mattresses feel bouncy and breathable. Modern versions like the Saatva Classic, a coil-on-coil design with a Euro pillow top, add comfort layers so they're not the stiff spring beds of decades past.

Adjustable air beds

Air beds such as the Sleep Number c2 let each partner set their own firmness. They solve the "we disagree on firmness" problem, but they require the brand's pump and base system.

Step 5: Decide how much cooling you need

If you regularly wake up hot, cooling deserves real weight in your decision. What helps most is airflow, not marketing language.

• Coil cores (hybrids, innerspring) let air move through the mattress.
• Latex sleeps more neutral than dense memory foam.
• Phase-change or cooling-fiber covers can make the surface feel cool to the touch, though that sensation can fade as the night goes on.
• Very soft, dense memory foam that you sink deep into is the classic hot-sleeper mistake.

Our best cooling mattress list ranks options with the strongest cooling ratings, from budget all-foam picks like the Cocoon by Sealy Chill to coil models like the Purple Restore Hybrid. Bedding matters too: breathable sheets and a non-plastic protector help.

Step 6: Think about your partner

Sharing a bed adds three questions:

• Motion isolation: If one of you is a light sleeper or keeps different hours, memory foam and foam-heavy hybrids absorb movement best.
• Edge support: Couples use more of the mattress surface, so strong edges matter more. Hybrids usually win here.
• Size and firmness disagreements: A king gives each person about the width of a twin XL. If you truly need different firmness levels, look at a split king or an adjustable air bed.

Our best mattress for couples list balances motion isolation with edge support. For size questions, see the mattress sizes guide.

Step 7: Account for pain and pressure points

If you have back, hip or shoulder pain, the right mattress keeps your spine in a neutral line while relieving the pressure points your position loads up. That usually means medium-firm support with a comfort layer that cushions without letting the hips sink, and zoned support (firmer under the lower back) can help.

Start with our best mattress for back pain list. A mattress can make you more comfortable, but it isn't a treatment. If pain persists, check in with a doctor or physical therapist.

Step 8: Set your budget and read the policies

What a queen mattress costs

In the 25 mattresses we track, queen prices fall into three rough tiers (prices change often, so treat these as typical, not promised):

• Budget, under about $700 on sale: all-foam picks like the Siena Memory Foam and Zinus Green Tea, and the Allswell Hybrid, one of the cheapest hybrids around. Our best budget mattress list covers this tier.
• Mid-range, about $700 to $1,500: most popular online brands, including the Helix Midnight and the Nectar Premier Hybrid.
• Premium, $1,500 and up: luxury and organic options such as the Saatva Latex Hybrid and the Tempur-Pedic Adapt.

List prices are often far above what people actually pay. The Nectar Classic, for example, lists at about $1,615 for a queen but is often on sale for around $699. Our best time to buy a mattress guide explains the sales calendar.

Trials, returns and warranties

Your body can take a few weeks to adjust to a new mattress, so the trial is your safety net. Among the brands we track, trials range from 90 nights to 365 nights, and one budget pick has no trial at all, just a retailer return window. Before you buy, check:

• How long the trial is, and whether you must keep the mattress a minimum number of nights before returning it
• Whether returns are free or carry a fee
• What the warranty covers, and whether it's full or prorated

Our mattress trial and return policies guide compares every brand side by side.

Buying online versus in a store

Mattresses that ship compressed in a box are now mainstream, and they usually cost less than showroom models with similar materials. See the best mattress in a box list. Store shopping lets you lie down first, but ten minutes on a showroom bed tells you less than a few weeks at home, which is why the trial matters more than the test lie-down.

Decision table: match your needs to a mattress type

Common mistakes to avoid

• Buying the firmest mattress "for support." Support comes from keeping your spine aligned, not from hardness. Too firm is as bad as too soft for side sleepers.
• Trusting the brand's firmness label alone. Compare it with independent ratings.
• Ignoring the return fine print. A long trial is only useful if returning is realistic.
• Forgetting the foundation. Check that your bed frame or base suits the new mattress, and note whether the warranty requires a particular type of support.
• Judging in the first week. Give a new mattress a few weeks before deciding.
