> Editorial Note: I’m Heather Adams, and I cover sofas, tables, mattresses, and bedding. The picks here are evaluated on the materials layer — foam density, coil gauge, frame construction, and fiber content — against CertiPUR-US, OEKO-TEX, and BIFMA standards.
A full memory foam mattress has to solve a tight-space problem without feeling like a compromise. Full size gives you about 54 in x 75 in, which is enough for solo sleepers, guest rooms, teens, and smaller apartments, but foam density, height, and heat control decide whether it feels supportive after month 6. For deeper comparisons, see memory foam mattress, cooling memory foam mattress, memory foam vs spring mattress, latex vs memory foam mattress, and memory foam mattress topper.
How We Evaluated
I prioritized full-size foam builds with clear height specs, recognizable mattress brands, CertiPUR-US relevance, owner durability patterns, and practical room fit. Sleep Foundation guidance favors pressure relief, motion isolation, and support alignment as core foam-mattress criteria, while CertiPUR-US focuses on foam content, emissions, and durability standards. Simple, but not soft thinking.
Pros
- Pressure-relieving memory foam adapts to body curves and sleep positions
- Green tea infusion adds natural cooling and freshness
- Breathable structure prevents overheating during sleep
- Consistent firmness across different temperatures and seasons
- Strong value at $139.99 for a full-size memory foam mattress
Cons
- Only 8 inches thick, thinner than premium memory foam mattresses
- No customer reviews yet to verify long-term durability
- May need a few days to fully expand and air out after unboxing
This EGOHOME mattress brings memory foam comfort into reach for anyone upgrading from a spring mattress or furnishing a guest room on a budget. The 8-inch profile keeps it simple while the patented foam does the real work: conforming to your shoulders and hips, filling gaps along your spine, and absorbing movement so you can sleep through the night undisturbed.
The green tea gel infusion is a nice touch that sets it apart from basic foam mattresses. It helps wick away body heat and adds a subtle freshness that keeps the mattress feeling clean. The medium-firm feel hits a sweet spot for most sleepers, whether you're on your back, side, or stomach, and the breathable cell structure means you won't wake up sweaty.

1. EGOHOME Full Size Memory Foam Mattress 8 Inch, Green Tea, Medium Firm — Firmer feel for simple guest-room support
This EGOHOME 8 in full mattress is the cleanest pick for shoppers who want a medium-firm foam bed without climbing into a 12 in profile. The green tea foam angle targets freshness, while the 8 in height keeps it workable for bunk-compatible frames, trundles, and low platforms. It won’t feel plush, and that’s the point. For back sleepers, teens, or a guest room that needs predictable support, this one wins on practicality. Rating listed: ?.
2. Zinus 6 Inch Full Green Tea Memory Foam Mattress, Medium Firm Feel — Low-profile choice for tight setups
The Zinus 6 in Green Tea model is the thinnest mattress here, so it’s best for temporary rooms, kids’ rooms, daybeds, and frames where a tall mattress creates rail or clearance issues. Six inches isn’t much cushioning for heavier adults, but the medium-firm feel keeps it from collapsing into a marshmallow. Zinus is also a familiar boxed-mattress name, which helps when you’re comparing owner reports and replacement expectations. This isn’t luxury. It’s compact, simple, and price-conscious. Rating listed: ?.
3. Zinus 8 Inch Full Cooling Essential Memory Foam Mattress, Medium Feel — Softer contour with a cooler brief
The Zinus 8 in Cooling Essential is the better Zinus option if the 6 in build feels too spare. You get 2 extra inches of foam height and a medium feel rather than a clearly firmer profile, which suits side sleepers who want more shoulder give. Cooling foam won’t make memory foam feel like innerspring airflow, but it may reduce the dense, heat-trapping sensation that cheaper foam beds can develop. For a full-size guest bed that adults may actually use, I’d start here. Rating listed: ?.
4. EGOHOME Full Size Memory Foam Mattress, 10 Inch Bed Mattress in a Box with Cooling Green Tea Gel, Relieve Pressure with — Better thickness for daily adult sleep
The 10 in EGOHOME is the more serious daily-use choice from the brand. That extra 2 in over the 8 in version matters for adults because it adds room for comfort foam over support foam, which can reduce the “bottoming out” feel on slatted frames. Cooling green tea gel is the headline feature, but the practical benefit is balanced height: tall enough for regular use, not so tall that sheets or low headboards become awkward. The title is oddly clipped, but the spec is clear. Rating listed: ?.
5. Novilla Bliss Full Mattress, 12 Inch Gel Memory Foam Full Size Mattress — Tallest feel with more cushion depth
The Novilla Bliss is the tallest mattress in this group at 12 in, so it’s the pick for sleepers who want a fuller bed profile and more foam depth. Gel memory foam may help with heat dispersion compared with basic visco foam, though airflow still depends on sheets, room temperature, and foundation style. The extra height also makes it easier to pair with standard bedroom furniture without looking underbuilt. For side sleepers and adults who dislike thin foam, Novilla has the strongest cushion case.

How to Choose a Full Memory Foam Mattress
Start with height. A 6 in mattress is usually for kids, bunks, daybeds, or short-term guest use, while 8 in works for lighter adults and mixed-use rooms. A 10 in or 12 in full mattress is safer for daily adult sleep because there’s more space for comfort foam and support foam.
Then check feel. Medium firm usually suits back sleepers and stomach sleepers better, while medium foam often gives side sleepers more shoulder and hip contouring. CertiPUR-US matters because it gives a baseline for foam content and emissions. Not glamorous. Useful.
8 Inch vs 10 Inch vs 12 Inch Full Memory Foam Mattresses
An 8 in full memory foam mattress is the middle ground for smaller bedrooms because it keeps the bed lower and easier to dress. It’s also lighter to move, which matters in apartments and guest rooms. The trade-off is less deep compression support for heavier adults.
A 10 in mattress is the safer daily-use spec for most adults, while 12 in feels more substantial and visually balanced on a standard frame. Apartment Therapy often emphasizes scale in small bedrooms, and this is where full size helps: 54 in wide saves floor space while still leaving a real sleep surface.
Frequently Asked Questions
Is a full memory foam mattress big enough for adults?
Yes, for one adult. A full mattress is about 54 in wide and 75 in long, giving more width than a twin but less length than a queen. Taller sleepers over 6 ft may feel cramped, especially if they sleep stretched out.
What thickness is best for a full memory foam mattress?
For daily adult use, 10 in is the safest starting point. An 8 in mattress can work for lighter sleepers or guest rooms, while 6 in is better for kids, daybeds, and occasional use. A 12 in model adds more cushion depth and bedroom presence.
Do memory foam mattresses sleep hot?
They can, because dense foam hugs the body and can hold warmth. Cooling gel, breathable covers, and lower-thread-count cotton sheets may help. Room temperature matters too. If you already sleep warm, choose cooling-focused foam over basic green tea foam.
Is medium firm good for back pain?
Medium firm foam may help some sleepers keep better spinal alignment, especially back sleepers. It isn’t a medical fix, and pain can come from many causes. If discomfort continues, a clinician is the right source, not a mattress spec sheet.
Can I use a full memory foam mattress on slats?
Yes, if the slats are close enough and the frame is stable. Many foam mattresses work best with slats spaced about 3 in apart or less, though brand guidance should lead. Wide gaps can create sagging and reduce support over time.
How long should a full memory foam mattress last?
A decent memory foam mattress often lasts 6 to 8 years with regular rotation, a solid foundation, and normal body weight ranges. Thinner 6 in models may show wear sooner. Owner reports on r/Mattress often flag sagging and heat retention as the first complaints.
Bottom Line
The EGOHOME 8 Inch Green Tea Medium Firm is my first pick because it’s practical, supportive, and sized right for the rooms where full mattresses usually live. Choose the Zinus 8 Inch Cooling Essential if you want a softer medium feel with a stronger cooling angle. If this is your main adult bed, the EGOHOME 10 Inch or Novilla 12 Inch makes more sense than a thin 6 in build.
