If you've ever stood in a mattress showroom surrounded by dozens of options — all claiming to be "the best" — you know how overwhelming the category can feel. Memory foam vs. hybrid vs. innerspring vs. latex. Firm vs. soft. Cooling vs. contouring. The truth is, there's no single best mattress type. There is, however, a best mattress type for you — determined by how you sleep, how much you weigh, how hot you run, and what you're actually asking a mattress to do for your body every night.
Sleep position determines spinal alignment — and spinal alignment determines what firmness and support profile your mattress needs to deliver. This is the most important single variable in mattress selection.
Side sleeping is the most common sleep position, and it creates specific pressure points at the shoulder and hip — the widest parts of the body that contact the mattress surface. A mattress that's too firm won't allow those points to sink in sufficiently, creating lateral pressure that can lead to shoulder pain, hip discomfort, and disrupted circulation over time.
Side sleepers generally need: A softer to medium comfort layer (2–4 inches of foam or micro-coils) that allows the shoulder and hip to sink in while the waist is supported. Memory foam and soft-medium hybrids are the most commonly recommended types.
For a full breakdown on firmness for side sleepers, see our guide on how to choose mattress firmness.
Back sleeping is the second most common position and is generally the most neutral for spinal alignment — provided the mattress is supportive enough. The key concern is lumbar (lower back) support: a mattress that's too soft allows the lower back to sink excessively, creating a hammock effect that strains the lumbar spine. Too firm, and the natural lumbar curve loses its support.
Back sleepers generally need: Medium-firm to firm support — typically 6–7 out of 10 on a firmness scale. Hybrid mattresses and firmer innersprings work well. Some back sleepers with pressure sensitivity do well with a medium-firm memory foam.
Stomach sleeping is the least common position and the most demanding for mattress design. When sleeping on the stomach, the heaviest part of the body — the torso — presses into the mattress center. A soft mattress allows the torso to sink below the alignment of the legs, creating an arch in the lumbar spine that can cause significant lower back strain over time.
Stomach sleepers generally need: Firm to very firm support — typically 7–9 on a firmness scale. A mattress that sinks under body weight is not suitable for stomach sleeping. Innerspring and firm hybrid mattresses are the most appropriate choices.
Combination sleepers shift positions throughout the night — most commonly between side and back, but sometimes all three. The challenge is finding a single mattress that supports both the pressure relief needs of side sleeping and the lumbar support needs of back sleeping.
Combination sleepers generally need: Medium firmness with responsive bounce. A mattress that's too slow to respond (like very dense memory foam) will feel like you're fighting the mattress every time you shift. Hybrids and latex — which recover quickly when you move — tend to work better for combination sleepers than slow-response foam.
| Sleep Position | Recommended Firmness | Best Mattress Types | Avoid |
|---|---|---|---|
| Side Sleeper | Soft to Medium (3–6) | Memory foam, soft hybrid | Firm innerspring |
| Back Sleeper | Medium-Firm (6–7) | Medium-firm hybrid, firm foam | Very soft foam |
| Stomach Sleeper | Firm to Very Firm (7–9) | Firm innerspring, firm hybrid | Memory foam, soft latex |
| Combination Sleeper | Medium (5–6) | Hybrid, latex, responsive foam | Very dense slow-response foam |
Research from the National Sleep Foundation indicates that approximately 74% of Americans are combination sleepers — meaning they change positions at least once per night. If you think you're a "side sleeper" but often wake on your back, a responsive medium mattress may serve you better than a dedicated side-sleeper model.
Body weight significantly affects how a mattress performs for any given sleep position. A "medium-firm" mattress feels very different to a 130-pound person than to a 250-pound person — because the compression load is entirely different.
Lighter sleepers don't compress mattress foams as deeply as average-weight sleepers. This means a mattress that feels "medium-firm" to an average-weight sleeper may feel notably firm to a lighter person. Lightweight sleepers often do better with a softer feel than the standard recommendation for their sleep position would suggest.
Most mattress firmness recommendations are calibrated for this range. Standard recommendations for sleep position apply relatively accurately. A medium or medium-firm mattress for the appropriate sleep position will typically perform as expected.
Heavier sleepers compress mattress materials more deeply, which affects both feel and durability. A mattress that feels "medium" will feel softer — and may become problematic for alignment over time. Key considerations for heavier sleepers:
Sleeping hot is one of the most common complaints about mattresses — and it's one of the most predictable issues to plan around. Mattress type plays a significant role in temperature regulation.
If you frequently wake up warm, kick off covers, or feel like the mattress is retaining heat, temperature regulation should be a primary factor in your selection. Dense memory foam is the biggest offender — it surrounds the body and restricts airflow, trapping body heat. Options for hot sleepers:
If you frequently feel cold at night and appreciate the body-conforming warmth of a mattress, memory foam's heat retention becomes an asset rather than a liability. Dense foam wraps around the body in a way that innerspring and hybrid mattresses don't, providing a warmer sleep environment.
Memory foam mattresses use viscoelastic polyurethane foam to conform to the body's shape under heat and pressure. The result is a "sinking in" sensation that many sleepers find comfortable for pressure relief and pain reduction.
Best for: Side sleepers, couples with motion sensitivity, those with shoulder/hip pressure issues, cold sleepers who want body warmth
Avoid if: You sleep hot, tend to feel "stuck" in foam, prefer responsive bounce, or sleep primarily on your stomach

Hybrid mattresses combine a pocketed coil support layer with comfort layers of foam, latex, or micro-coils on top. The result bridges the gap between the pressure relief of foam and the support and airflow of innerspring.
Best for: Back sleepers, combination sleepers, hot sleepers who still want some foam comfort, couples who want a balanced choice
Avoid if: You need maximum motion isolation, or budget is the primary concern
For an in-depth comparison, see our guide on hybrid vs. innerspring mattresses. Browse our hybrid mattress collection.
Traditional innerspring mattresses use a coil support system as the primary component, with a relatively thin comfort layer on top. Modern innerspring designs use individually wrapped (pocketed) coils that reduce motion transfer compared to older interconnected coil systems.
Best for: Stomach sleepers, back sleepers who prefer minimal sink-in, hot sleepers, those who prefer a traditional bouncy feel
Avoid if: You're a side sleeper needing pressure relief, or you share a bed with a restless partner
Latex mattresses use either natural rubber latex or synthetic latex as the primary material. Natural latex (from rubber trees) is the more premium option, with GOLS certification available for organic sourcing. Latex has a distinct feel — responsive and slightly bouncy, unlike the slow-recovery of memory foam.
Best for: Combination sleepers who want natural materials, buyers prioritizing long-term durability, those who dislike the "sinking" feel of memory foam
Avoid if: You have a latex allergy, or are optimizing for budget

Hybrid mattresses have become the fastest-growing mattress category in the US over the past five years. Their combination of responsive coil support and foam comfort appeals to the largest share of sleepers — and their ability to work across sleep positions makes them the most versatile single recommendation for most buyers.
Firmness and mattress type are related but separate decisions. Most mattress types are available across a range of firmness levels — from a plush memory foam to a firm hybrid. Once you've identified the right type for your sleep position and body, the firmness layer is a more granular adjustment.
Industry-standard firmness scale:
For a deeper dive into the firmness decision, see our guides on firm vs. soft mattresses and how to choose mattress firmness.
When two people with different sleep positions and body types share a mattress, compromise is inevitable — but the right mattress can minimize it. Here's how to approach the decision:
Use this framework to narrow your choice:
The more you can narrow this framework before you visit a store, the more efficient and confident the in-store testing process becomes. Rather than testing 20 mattresses, you can focus on the 4–5 that genuinely match your profile.
At LA Mattress Stores, the sleep consultation is built around this exact framework — starting with position, adding body type, layering in temperature preference, and arriving at a shortlist worth testing. The goal is to match you with the right type, not just the right brand.

Mattress type is one of the most consequential purchases you'll make for your physical wellbeing — but the decision framework doesn't have to be overwhelming. Start with sleep position. Layer in body weight. Factor in temperature preference. Then match those parameters to the type characteristics outlined above.
The best mattress isn't the most expensive one, or the most popular brand, or the one with the most glowing reviews. It's the one that's right for your specific combination of sleep position, body type, and preferences. A systematic approach gets you there far more reliably than shopping by brand name or online reviews alone.
When you're ready to test options in person, browse the full mattress collection first, then visit a location to feel the difference between types side by side.

(800) 218-3578Side sleepers typically do best on memory foam, latex, or soft-to-medium hybrid mattresses. These materials cushion the hips and shoulders, which bear the most weight in a side-sleeping position. A mattress that's too firm creates pressure at those contact points and can lead to numbness or soreness over time.
Neither is universally better — it comes down to personal preference. Memory foam offers deep contouring and motion isolation, making it great for light sleepers and those with joint pain. Hybrids combine foam comfort layers with a coil support core, which provides more bounce, better edge support, and tends to sleep cooler. If you run hot or want more responsiveness, a hybrid is usually the better pick.
Medium-firm hybrid or latex mattresses are frequently recommended for back pain because they balance spinal support with enough give to relieve pressure. Pure memory foam works well for some back pain sufferers, particularly those who need contouring relief. The most important factor is maintaining a neutral spinal alignment in your preferred sleep position.
Traditional innerspring mattresses have largely been replaced by hybrids, which add foam comfort layers on top of a coil base for better pressure relief. Basic innersprings can feel bouncy and lack contouring. That said, firm innerspring models can still work well for stomach sleepers and those who prefer a very traditional feel with minimal sink.
Latex and hybrid mattresses tend to sleep the coolest because their open-cell or coil structures allow for better airflow. Traditional memory foam retains more heat, though modern gel-infused and open-cell memory foam versions have improved significantly. If you're a hot sleeper, look for a hybrid with a breathable cover material and avoid dense, closed-cell foam layers.
Your sleep position is the biggest guide: side sleepers generally need soft-to-medium (3–5 on a 10-point scale), back sleepers do well in the medium-to-firm range (5–7), and stomach sleepers usually need firm support (7–9) to prevent the hips from sinking. Body weight also plays a role — heavier sleepers often need a firmer mattress to get adequate support from the same model.
