A full mattress is 54 by 75 inches, and that footprint fools people. The number that actually decides whether you sleep well is thickness, and it has to match your body weight and your base, not your budget. A 5-inch slab that’s perfect on a bunk will bottom out under a 200-pound side sleeper. Foam density matters more than the price tag, too; a dense 8-inch bed can outlast a cheap 12-inch one. Before you buy, sort out the platform underneath with a full size box spring, decide how much push-back you want against a firm mattress, match it to the right full bed frame, plan for a mattress topper if you like extra cushioning, and consider a bed wedge pillow if you sleep propped up. Here’s how the five picks below break down by height and sleeper.
How We Evaluated
Every pick fits the standard full footprint of 54 by 75 inches and ranges from 5 to 10 inches thick. We weighted foam density first. Higher density resists the year-one sag that shows up in owner reports on r/Mattress. All five carry CertiPUR-US certification, meaning the foam is made without ozone depleters, formaldehyde, or heavy metals. We looked for gel infusion or open-cell structure for heat dispersion, since foam traps warmth. Edge support, firmness on the 1–10 scale, and a rating floor of 4.3 rounded out the criteria. Sleep Foundation protocols shaped how we read firmness against sleeper weight.
Pros
- Effective pressure relief for side and back sleepers
- Green tea infusion adds cooling properties and freshness
- Fits body curves well and reduces motion transfer
- Works in varying temperatures and humidity levels
- Affordable entry point into memory foam comfort
Cons
- No customer reviews yet to verify long-term durability
- 8-inch thickness may feel too firm for strict side sleepers
- May need time to fully expand and off-gas after unboxing
This mattress gets memory foam basics right without overthinking it. The green tea gel infusion is a nice touch that actually helps with temperature regulation, and the medium firm feel hits that sweet spot where most sleepers will feel supported without sinking in too much.
The 8-inch profile keeps it simple and compatible with most bed frames, while the bubble hole structure does a decent job moving air through. It is not a luxury mattress, but for a guest room, teen bedroom, or first apartment, it delivers genuine memory foam contouring at a price that makes sense.
If you want memory foam comfort and cooling properties without spending $400-plus, this one delivers.
Styles it works with: Minimalist, Modern, Scandinavian, Budget-Conscious Decor
Best placed in: Guest bedroom, teen or college dorm room, spare room on platform bed or slatted frame
May not suit: Master bedrooms where premium comfort is priority, homes needing extra thick mattresses for high bed frames, strict side sleepers who need plush cushioning over 10 inches
Buy it if:
- You need an affordable full-size mattress for a guest room or dorm
- You sleep hot and want built-in cooling without a separate topper
- You prefer medium firm support and sleep on your back or stomach
Consider waiting if:
- You want to see verified customer reviews before committing
- You need time to compare with other budget memory foam options
Skip it if:
- You are a side sleeper who needs plush cushioning over 10 inches thick
- You want a mattress with an established track record and hundreds of reviews

1. EGOHOME 8 Inch — The Guest-Room Default
At 8 inches, the EGOHOME full is the height most light-to-average sleepers should default to. It’s built for people under 180 pounds who sleep on their back or side, and it slots perfectly into a guest room that sees weekend use. The cooling cover and gel-infused top layer pull heat away better than plain memory foam, which is the usual complaint with beds this cheap. Owners rate it 4.3, and the recurring note is that it sleeps cooler than expected for the price. Firmness lands around medium, roughly a 6 on the 10-point scale, enough contour for a side sleeper’s shoulder without swallowing a back sleeper. The trade-off is edge support; sit on the very rim and you’ll feel it dip. For a spare room or a lighter adult who wants gentle pressure relief, it’s the honest starting point.
2. Novilla 10 Inch Gel — Best for Average-Weight Combo Sleepers
The Novilla 10-inch gel memory foam is the pick for combo sleepers between 130 and 200 pounds who shift positions all night. Ten inches gives it a comfort layer deep enough to cradle a side-lying hip plus a support core that keeps a back sleeper from sinking. It reads medium-firm, close to a 6.5, and the gel beads plus a breathable knit cover handle heat well for an all-foam bed. Owners give it 4.4, and durability reports lean positive past the one-year mark; the layer that flattens first on cheaper foams holds here. Motion isolation is a quiet strength; a restless partner won’t wake you. It’s a touch heavier to move than the thinner picks, so plan for two people on setup day. For most adults on a full, this is the balanced middle.
3. EGOHOME 10 Inch — When You Want It to Last
The EGOHOME 10-inch is the one to buy if this full is your primary bed and you’re on it every night. The extra height over the brand’s 8-inch model adds a denser support core, which is what average-to-heavier sleepers up to about 230 pounds need to avoid bottoming out. It’s medium-firm, near a 7, and the memory foam contours the lower back in a way that may help ease morning stiffness for back and side sleepers. The bed-in-a-box compression means it arrives tight and expands over 24 to 48 hours; give it the full window before judging firmness. Owners rate it 4.3 and single out how it holds shape at the edges better than thinner EGOHOME versions. If you’re choosing between the 8 and the 10 for daily use, spend the little extra and get the 10.
4. EGOHOME 5 Inch Green Tea — Best for Bunks and Kids’ Rooms
At just 5 inches, the EGOHOME Green Tea full is purpose-built for bunk beds, trundles, daybeds, and kids under 100 pounds. That slim profile is a feature, not a compromise: bunk safety rails are sized for low mattresses, and a thick bed defeats them. The green-tea-infused foam adds odor control, and the low height keeps a child from rolling over a guardrail. It’s firmer-feeling because there’s less foam to sink into, good for small bodies, not for an adult’s primary sleep. Owners give it 4.4 and mention how well it fits standard bunk frames without gaps. Don’t put a grown side sleeper on this; five inches won’t cushion an adult hip. For a kid’s room, a loft, or a camper bunk, it’s exactly the right amount of mattress.
5. Novilla 10 Inch Gel — Best Plush Feel for Side Sleepers
This second Novilla 10-inch reads softer than its sibling above, a plusher gel memory foam tuned for dedicated side sleepers who want the shoulder and hip to sink in. Call it a medium, around a 5.5 on the scale, with a quilted cover that adds a pillowy first inch. Side sleepers under 160 pounds get the pressure relief they’re after without the sunk-in feeling of true memory foam. It shares the 4.4 owner rating and the same cooling gel, but the softer top layer means back sleepers may feel undersupported here. That’s the honest split between the two Novillas: the firmer one for combo and back sleepers, this plusher one for committed side sleepers. If you wake with a sore shoulder on a firm bed, this is the one to try.

Matching Thickness to Sleeper Weight and Base
Thickness isn’t about luxury. It’s about not bottoming out. Here’s the working rule. Under 100 pounds, or on a bunk, 5 inches is plenty and often safer. Between 100 and 180 pounds, 8 inches gives enough comfort layer for back and lighter side sleepers. Over 180 pounds, or any dedicated side sleeper, go to 10 inches so your hip and shoulder don’t press through to the core. The base underneath changes the math, too. Foam mattresses need a solid or slatted platform with gaps no wider than 3 inches; wider gaps let the foam sag between slats and void most warranties. A traditional box spring alone isn’t ideal for foam; pair it with a bunkie board or switch to a platform frame. Heavier sleepers should also weigh foam density, not just height: a dense 8-inch bed can outperform a floppy 10-inch one. And remember the footprint stays fixed at 54 by 75 inches regardless of height, so a taller mattress only changes the feel, never the sleeping area.
8 Inch vs 10 Inch, Memory Foam vs Gel
The 8-versus-10 choice comes down to weight and use. Eight inches suits guest rooms and sleepers under 180 pounds; 10 inches is the daily-driver height for average and heavier bodies because the deeper support core resists sag. Spend the extra only if the bed sees nightly use. On material, standard memory foam contours hardest and isolates motion best, but it runs warm. Gel-infused foam adds beads or an open-cell structure that moves heat off the surface, so light sleepers and anyone who wakes up hot should lean gel. Neither fully solves overheating on its own — a breathable cover and a cool room do more than marketing claims suggest. Both types here are CertiPUR-US certified, so off-gassing is minimal and fades within a few days of unboxing.
Frequently Asked Questions
What are the exact dimensions of a full mattress?
A full is 54 inches wide by 75 inches long. That’s 15 inches wider than a twin but 5 inches shorter than a queen, which is why taller adults sometimes find their feet near the edge.
How thick should a full mattress be?
It depends on weight. Under 100 pounds or on a bunk, 5 inches works. Between 100 and 180 pounds, 8 inches. Over 180 pounds or any side sleeper, 10 inches so you don’t feel the core.
Is a full mattress big enough for two adults?
Barely. At 54 inches wide, each person gets 27 inches — narrower than a crib. It’s fine for couples short on room, but a queen gives 30 inches each and sleeps far better.
Does a memory foam full need a box spring?
No. Foam wants a solid or slatted platform with gaps under 3 inches. A bare box spring flexes too much and can void the warranty. Add a bunkie board or use a platform frame.
Do these mattresses sleep hot?
The gel-infused Novilla and EGOHOME 8-inch run cooler than plain memory foam thanks to gel beads and breathable covers. No foam bed is truly cool, so a ventilated room helps.
Can a full mattress help with back pain?
A supportive medium-firm foam may help by keeping the spine aligned, but no mattress cures back issues. Match firmness to your sleep position and see a professional for persistent pain.
Bottom Line
The Novilla 10-inch gel is the one most people should buy — it balances contour and support for average combo sleepers and runs cooler than plain foam. If this is a guest bed or you’re under 180 pounds, the EGOHOME 8-inch saves money without giving up much. Buying for a bunk or a kid’s room? The 5-inch Green Tea is the safe, correctly-sized choice. Just remember: on a full, thickness and foam density decide comfort far more than the price on the box. Measure your frame first, confirm the slats sit no more than 3 inches apart so the foam won’t sag between them, and give any boxed bed 48 to 72 hours to fully expand before you judge the feel.
