Ranked for this guide by our testers. Scores are each product’s overall test result out of 5.
If you wake up with a numb shoulder or an achy hip, or your partner's every toss jolts you awake, memory foam is probably what you're after. It cradles pressure points and soaks up movement in a way coils can't. The problem is that foam beds look identical online, and a cheap one can sag or sleep hot within a year.
We pressure-mapped, heat-tested and slept on six all-foam mattresses, from a budget gel bed to a 14-inch build, and weighed each against what it costs. My quick answer: the Nectar Classic is the best memory foam mattress for most people, and the MLILY EgoHome is the value pick if you want more foam for less.

How We Tested Memory Foam Mattresses
Memory foam lives or dies on three things: how well it relieves pressure, how hot it gets and how much motion it passes. We measured all three.
- Pressure mapping at the shoulder and hip with side sleepers of different weights. Readings well under the 32 mmHg discomfort threshold count as strong.
- Thermal testing, recording how far the surface rose above room temperature after two hours.
- Motion transfer using a drop test, with the threshold you can feel at about 0.15 mm.
- Edge, odor and setup checks, including a 60 lb perimeter load and how quickly new-foam smell faded in a ventilated room.

Layla 10" Copper Infused Memory Foam Mattress
A flippable foam mattress with a soft side and a firm side, plus copper foam that runs cooler than plain memory foam.
- Type
- Memory Foam
- Firmness
- Soft / Firm (Flippable)
- Trial
- 120 nights
- Warranty
- Lifetime
- Genuinely flippable design
- Copper-infused memory foam on the comfort layer runs measurably cooler than standard uninfused foam in our thermometry testing

- Edge support is only average
Layla Copper Memory Foam
The Layla Copper Memory Foam removes the biggest risk of buying foam online: guessing the wrong firmness. One side is soft for deep shoulder and hip cushioning, the other firm for back and stomach support, and you simply flip it if your first choice is wrong.
The soft side rates about 4/10 and the firm side about 7/10, and vibration was barely perceptible across the bed.
Side sleepers who want deep cushioning, shoppers unsure of their firmness, and light sleepers with a restless partner.
You sit on the edge often; edges were its weakest area, so look at the Casper Original Hybrid.
Copper helps, but it still ran warmer than a coil hybrid. You get a 120-night trial and lifetime warranty.

Novaform Advanced 14" Gel Memory Foam Mattress
A deep gel-foam mattress with excellent motion isolation for light sleepers sharing a bed; still sleeps warmer than a hybrid.
- Type
- Memory Foam
- Firmness
- Medium
- Trial
- Costco returns
- Warranty
- 20 years
- A tall 14-inch all-foam build gives the gel memory foam comfort layer real depth, so shoulder and hip pressure relief holds up for most body types
- Excellent motion isolation, among the quietest mattresses we tested for light sleepers sharing a bed
- Gel-infused foam runs cooler than plain memory foam, which narrows (but does not close) the heat gap with hybrids
- All-foam construction still sleeps warmer than a hybrid, even with gel infusion
- Edge support is only average, and the perimeter compresses visibly when you sit on it
Novaform Advanced 14" Gel Memory Foam
The Novaform Advanced 14" Gel Memory Foam is a thick all-foam bed with a gel memory foam comfort layer. It cradles shoulders and hips deeply and was among the quietest beds we tested for light sleepers.
Pressure mapping showed broad, even distribution with no hot spots, and the 14-inch build kept even heavier side sleepers off the base.
Side sleepers who want deep cushioning, light sleepers with a restless partner, and people who find thin foam beds flimsy.
Value matters most; the Nectar Classic and MLILY EgoHome gave similar comfort for much less.
It costs well above comparable foam beds, and returns go through Costco. It carries a 20-year warranty.

How to Choose a Memory Foam Mattress
Look for real pressure-relief data
Pressure relief is the reason to choose foam over a hybrid. Look for pressure-mapping results showing shoulder and hip readings well below the discomfort threshold, not just a promise of "contouring comfort."
Comfort layer depth matters. Look for at least 3 inches of dedicated comfort foam over a supportive base. Anything thinner tends to bottom out for heavier sleepers, who compress through to the firm base and lose the contouring benefit.
Memory foam and heat
Traditional memory foam traps heat because it hugs you closely and has no coil airflow. Gel infusion, open-cell foam and breathable covers narrow the gap with hybrids but don't close it. Every foam bed here warmed by about 5°F or more in our tests, apart from what copper and gel shaved off.
If you sleep hot and pressure relief isn't your top priority, a hybrid will likely serve you better. See our best cooling mattress guide.
Firmness by sleep position and weight
Side sleepers do best on medium to medium-firm foam that lets the shoulder and hip sink in. Back sleepers want medium-firm support that keeps the lower back level. Strict stomach sleepers usually find memory foam lets the hips sink too far.
Sleepers over roughly 230 lbs need a thicker, higher-density comfort layer, and several of our picks list that weight as a reason to skip. At that weight, compare our best mattress for heavy people picks, many of which are hybrids.
Density and durability
Foam density, measured in pounds per cubic foot (PCF), is the best single predictor of how long foam holds its shape. Budget foam often runs 2.5–3.5 PCF and can show body impressions within 2–3 years of nightly use, while 4+ PCF comfort foam tends to last longer.
Higher density also means slower, deeper contouring, which is part of why premium foam feels different even before either bed shows wear. Reputable brands list density in their spec sheets; if a listing doesn't, treat that as a yellow flag.
Certification and off-gassing
CertiPUR-US certification confirms the foam meets low-VOC, low-emissions standards; our CertiPUR-US explained guide shows what the label covers. GREENGUARD Gold, which the Zinus also carries, tests for a wider range of chemical emissions.
New foam usually smells for the first 24–72 hours as trapped compounds dissipate. That's normal and not a safety sign, but air the mattress in a ventilated room before sleeping on it.
Buy memory foam if you are:
- A side sleeper with shoulder or hip pressure
- Sharing a bed with a restless partner
- Someone who likes a slow, hugging, no-bounce feel
- You sleep hot or wake up sweaty (see our best hybrid mattresses)
- You sleep mostly on your stomach
- You sit on the edge of the bed a lot
Memory Foam vs. Hybrid: Which Should You Choose?
Memory foam wins on pressure relief and motion isolation, the slow, deep contouring a coil hybrid can't fully copy. It loses on temperature and responsiveness, because dense foam traps more heat and takes longer to move on. Does memory foam sleep hot? Dense all-foam beds hold more heat than hybrids, which is why the gel and open-cell picks above matter if you run warm.
If joint relief is your priority and your room stays cool, foam is the better default. If you run hot or change position a lot, read our hybrid vs memory foam guide.
Final Verdict
The Nectar Classic is the memory foam mattress I'd recommend first. It delivers deep, quiet pressure relief for side sleepers and couples, and its 365-night trial and lifetime warranty make it the lowest-risk foam purchase we've tested.
If you want the most foam for your money, the MLILY EgoHome is the value alternative; if you're not sure how firm to go, the Layla Copper Memory Foam lets you flip. Ready to decide? Read our full Nectar Classic review for sizes and today's price.
Frequently Asked Questions
What is the best memory foam mattress overall?
The Nectar Classic. It combines deep, even pressure relief and very low motion transfer with a 365-night trial and lifetime warranty.
Is memory foam bad for hot sleepers?
It runs warmer than a hybrid because it lacks coil airflow. Gel-infused foam, like the Nectar Classic and Zinus Green Tea Cooling, narrows the gap but doesn't eliminate it, so very hot sleepers should look at a hybrid.
What is the best budget memory foam mattress?
The Zinus Green Tea Cooling. It's fiberglass-free, GREENGUARD Gold certified and includes cooling gel foam, which is rare at its price.
How long does a memory foam mattress last?
Quality memory foam typically lasts 7–10 years, while budget foam often shows impressions closer to 5–7 years. Our how long does a mattress last guide breaks it down by material.
Is memory foam good for side sleepers?
Yes. Its deep contouring cradles the shoulder and hip more thoroughly than most hybrid comfort layers.
Our Nectar Classic, MLILY EgoHome and Casper Element side-sleeper tests all showed low joint pressure.
Does new memory foam smell, and is that safe?
Yes, a temporary odor for the first few days is normal for CertiPUR-US certified foam. Air it out in a ventilated room; if a strong smell lasts well beyond a week, contact the manufacturer.
Do heavier sleepers need a different memory foam mattress?
Usually, yes. Above roughly 230 lbs you need a thicker, denser comfort layer to avoid bottoming out, and many sleepers at that weight do better on a hybrid.
See our best mattress for heavy people guide.
Why buy the Casper Element if the MLILY EgoHome costs less?
Mainly for its light weight and simplicity. At about 57 lbs it's easy to set up and move alone, while the EgoHome weighs 78 lbs.
If you're optimising purely for foam per dollar, the EgoHome wins.
Can I check foam density before I buy?
Yes, reputable brands list foam density in their spec sheets. If a listing doesn't state it anywhere, treat that as a yellow flag rather than assuming it meets the 4+ PCF level we recommend.
