How To Choose The Best Full Bed
The right full mattress depends on three things: how you sleep, who will use it, and where it will live (guest room or daily driver). Here is what to look for.
Thickness Matters
Mattress depth — 8 inches, 10 inches, or 12 inches and up — dictates both support and longevity. A thicker mattress usually contains more foam layers, which translates to better pressure relief and weight distribution. Thinner models (8 inches) often work well for kids or bunk beds but may not support heavier adults as effectively over time.
Foam Types and Construction
Pure memory foam offers deep contouring and motion isolation but can trap heat. Gel-infused memory foam adds cooling particles to pull heat away from your body. A hybrid mattress — memory foam plus pocket springs — gives you bounce, edge support, and airflow from the coils alongside the pressure relief of foam. Your choice depends on whether you tend to sleep hot and how much motion transfer bothers you.
Certifications and Safety
Check for CertiPUR-US certification (foam is free from heavy metals and formaldehyde) and OEKO-TEX Standard 100 (fabric is tested for harmful substances). These labels matter especially if the bed is for a child or someone with chemical sensitivities.

In‑Depth Reviews
1. PurrJoys Full Mattress, 12 Inch Cooling-Gel Memory Foam and Pocket Spring Hybrid
The hybrid build that blends coil support with foam comfort for almost any sleeper.
This mattress stands apart because it is a hybrid: individually wrapped pocket springs sit inside a memory foam core. The pocket springs work independently, which means when your partner tosses at night, you barely feel it — the motion isolation is excellent. The top layers use cooling-gel memory foam, so the bed breathes better than a standard all-foam model.
Buyers report after nearly a year of use the mattress remains comfortable and holds its shape without sagging. The medium firmness lands right in the middle — not hard, not overly soft — making it a safe bet if you are unsure which side you prefer. The dimensions are 54 x 75 x 12 inches, matching standard full-sheet sizing. The 12-inch depth gives enough foam and spring layers to support a range of body types without bottoming out.
Why it works for couples
- Pocket springs minimize motion transfer across a full-size surface
- Medium firmness suits side, back, and stomach sleepers
- Cooling-gel layer prevents that sweaty memory-foam feeling
One trade-off to know
- Full expansion takes up to 72 hours — it will feel usable sooner but give it time to reach full height
Reach for this if: you share a full bed with a partner or pet and need a mattress that stops movement from traveling across the surface.
Look elsewhere if: you prefer a very plush, sink-in feel — the hybrid spring layer adds a noticeable firmness that better suits medium-firm fans.
2. Zinus Green Tea Memory Foam Mattress 12 Inch
Zoned pressure relief that adapts to how you sleep without guessing.
This is the thicker 12-inch version of Zinus’s popular Green Tea line. The key feature is their patented zoned pressure relief — different areas of the foam respond differently to your body’s weight, giving you more cushion where you need it (shoulders, hips) and more support where you don’t. The foam is infused with green tea extract and purified charcoal to neutralize odors, and buyers confirm the initial smell dissipates quickly, usually within 24-48 hours.
Reviewers with back pain and scoliosis report that the medium-firm feel strikes a rare balance: soft enough to contour but firm enough to keep the spine aligned. The mattress is fiberglass free. At 12 inches deep, it works with most frames, platform beds, and adjustable bases. The motion isolation is strong — sleepers mentioned they did not feel partners or dogs moving on the other side.
Cooling note: Some users note the foam can retain heat in warm rooms. If you sleep very hot, pair it with a breathable mattress protector or consider a gel-infused alternative.
Grab this for: targeted pressure relief across different sleep positions — side, back, and stomach — without feeling like you are sinking into a hole.
skip it if: you want a cool-touch surface or live in a hot climate where foam naturally softens in warmth.
3. Novilla Mattress Full Size 12 Inch, Gel-Infused Memory Foam with Cool-Touch Nylon Cover
The cool-touch cover and gel foam layer that actually fight heat, not just claim to.
Novilla uses a two-layer cooling system: a cool-touch Nylon cover blended with 30% plant-infused fiber, plus NanoGEL-infused memory foam underneath. Owners mention the surface feels icy to the touch and stays comfortable through the night without overheating. The triple-layer foam construction (gel memory foam, cushioning foam, high-density support foam) targets pressure points on the hips and back while maintaining neutral spinal alignment.
Reviewers describe it as medium-firm — supportive without being too hard — and note that the motion isolation is strong enough that a partner’s movement does not disturb sleep. The Novilla is triple-certified: CertiPUR-US for foam emissions, OEKO-TEX for fabric safety, and ISPA for international sleep product standards. It comes with a 100-night trial and a 10-year warranty.
Why hot sleepers like it
- Cool-touch Nylon cover feels immediately cool to the touch
- NanoGEL memory foam prevents heat buildup in the core layers
- Triple-layer foam keeps spine aligned without sinking
One drawback
- The cool-touch fabric may feel less warm in very cold rooms — not an issue for most but note for drafty bedrooms
Ideal for: anyone who wakes up sweaty on standard memory foam and needs a legit cooling surface that does not wear off after a few hours.
Not for: sleepers who prefer a very deep, slow-sinking hug — the Novilla is responsive and supportive with less of that classic “quicksand” feel.
4. Signature Design by Ashley Chime Memory Foam 12″ Full Mattress
A thick base foam layer that holds its shape at the edges, ideal for heavier sleepers.
Ashley’s Chime mattress uses a thick layer of memory foam on top for contouring and an extra-thick base of firm support foam underneath. This combination gives it unusually good edge support for a foam mattress — you can sit or sleep right up to the edge without feeling like you are rolling off. Dimensions are 74 x 52 x 12 inches, which is slightly narrower than the standard 54-inch-wide full, so keep that in mind if you have tight-fitted sheets.
Buyers weighing over 300 pounds report the bed supports them without sagging, and the medium firmness works well for side sleeping. The mattress arrives compressed in a box; one reviewer noted the outer sections expanded in about an hour but the middle took two full days to reach full height. It is CertiPUR-US certified and comes with a 10-year non-prorated warranty.
Heavy-duty callout: Multiple reviews note this mattress holds up well under heavier users without developing a permanent dip in the middle — a common complaint with thinner all-foam models.
Pick this if: you are a heavier sleeper or someone who sits on the edge of the bed regularly and needs a mattress that does not collapse at the sides.
Think twice if: you need exact full-size width — the 52-inch width means some standard full sheets may fit loosely.
5. Avenco Full Mattress 12 Inch, Gel Memory Foam
Gel-infused memory foam with a removable, breathable cover at a competitive price point.
Avenco’s second full-size offering in this guide uses 30% NanoGel infused into the memory foam to improve heat absorption and airflow. The 3-layer foam structure (gel memory foam plus high-density support foam) absorbs noise and movement, and the Plant-Based foam layer helps resist odors and moisture. The 75 x 54 x 12-inch dimensions conform to standard full sizing, and the cover is removable — a useful feature for spot cleaning.
Buyers describe the feel as medium-firm with a satisfying body-hugging contour. One reviewer specifically called out the gel particles for providing effective cooling without the “icy” sensation some gel foams produce. Expansion is quick; most found it reached full size within 24 hours with minimal chemical smell. The mattress is CertiPUR-US certified.
What stands out
- 30% NanoGel infusion dissipates heat better than standard memory foam
- Removable cover makes cleaning easier than most foam mattresses
- Plant-Based foam layer resists moisture and odors
A small caveat
- Some users find it slightly firmer than expected for a “medium firm” rating — test with a topper if you prefer plush
Best for: hot sleepers on a mid-range budget who want real gel cooling without stepping up to a premium price tier.
Not ideal for: those who want a plush, pillow-top feel — this is a medium-firm mattress through and through.
6. Zinus 10 Inch Green Tea Cooling Memory Foam Mattress [New Version], Full
A thinner, cooling-gel version of the classic Zinus foam mattress at a lower entry point.
This 10-inch version of the Zinus Green Tea line offers the same cooling gel foam and green tea/charcoal infusions but with a thinner profile and a lower sticker price. The depth is 10 inches compared to the 12 inches of the other Zinus model in this guide (a 20% less gap in thickness). That makes it a good fit for platform beds, trundles, or guest rooms where a thinner mattress is perfectly acceptable.
Customers note the mattress is very firm at first — one reviewer had expansion issues where the bed only reached 8 inches after 72 hours (they fixed it by walking on the mattress to decompress it). Others found it comfortable for back pain but noted the smell took a few days to fully air out. The mattress is fiberglass free and CertiPUR-US certified. Allow 24–72 hours for full expansion.
Honest heads-up: Multiple reviews mention the initial inflation can be inconsistent compared to thicker models. If you buy this one, give it the full 72 hours and walk on it gently to help the foam decompress evenly.
Go for it if: you need a thinner full mattress for a low-profile bed frame or a guest room that gets occasional use.
Pass if: you want a thicker, more luxurious feel — step up to the 12-inch Zinus or another pick in this guide.
7. Avenco Full Mattress 12 Inch, Medium Firm for Back Pressure Relief
The medium-firm foam bed built specifically for back and pressure relief across all sleeping positions.
This Avenco model targets a single goal: keeping your spine aligned while you sleep. The dual-layer foam uses a breathable fabric cover and high-density foam core that contours to the body without letting you sink into poor posture. Reinforced edges provide firm edge support so the surface stays stable whether you sleep in the middle or near the border. The 75 x 54 x 12-inch dimensions are standard full size — 12 inches of depth, matching the Avenco Gel model above.
Buyers consistently highlight the quick expansion and minimal chemical smell. One reviewer called it “an amazing update for my sleep,” noting a reduction in morning stiffness after switching. The mattress is CertiPUR-US certified and comes with a 100-night risk-free trial. It uses high-density foam rather than gel foam, so heat retention is average — not as cool as the gel-infused Avenco option but not suffocating either.
Why back sleepers choose it
- Dual-layer foam targets spinal alignment without excessive sink
- Reinforced edges prevent roll-off for side sleepers
- Quick expansion and very low off-gassing smell
One limitation
- Firm feel may not suit strict stomach sleepers who prefer a softer surface
Ideal for: back sleepers and anyone waking up with lower back stiffness who needs a medium-firm foundation that supports without sagging.
Skip if: you are a hot sleeper who needs gel infusion — grab the Avenco Gel model instead for the cooling particles.
8. Nectar Premier 13” Full Mattress – Medium Firm
Nectar’s top-tier full with extra thickness, cooling fabric, and contouring memory foam.
The Nectar Premier is the upgraded version of Nectar’s classic line. At 13 inches thick, it is the tallest mattress in this guide, and it packs an extra inch of contouring memory foam compared to their classic model — which Nectar says provides 2X more pressure relief for the back and hips. The cover has 60% more cool-to-the-touch fabric than the standard model, and it uses an adaptive support layer designed to promote spinal alignment for all sleep positions.
Buyer experiences are mixed but mostly positive. One reviewer who initially thought the mattress was too soft after unboxing found it expanded fully and became supportive once placed on a platform bed — they noted excellent motion isolation and no more back pain. A lighter sleeper (150 lbs) found it slightly too firm for side sleeping but comfortable with a mattress topper. The mattress comes with a 365-night home trial and a Forever Warranty, which is the longest risk-free period in this lineup.
Platform preference: A strong pattern in reviews shows the Nectar Premier performs best on a solid platform or slatted base. On a box spring, the foam may not reach full shape.
Best for: adults who want a premium, thicker mattress with a long trial period and a Forever Warranty — a confident investment for your primary bedroom.
Not for: budget buyers or anyone who needs edge support for sitting — reviewers point out the edges lack firmness compared to hybrid models.
9. Nectar Kids Full Mattress 8” – 2-Sided Design for Growing Children
A flippable kids mattress that adjusts firmness as your child grows from toddler to teen.
This is a dedicated children’s mattress with a cleverly simple design: two firmness levels in one bed. One side is firmer, recommended for ages 3-7, to support a developing spine. Flip it over, and the other side is softer with more contouring memory foam, recommended for ages 8 and up. The 8-inch thickness is lower-profile than adult fulls but works naturally for bunk beds, trundles, and lower kid-height frames.
Buyers praise the lack of chemical smell compared to other memory foam mattresses — one buyer mentioned it expanded very fast with no odor at all. The cover is removable, stain-resistant, moisture-repellent, and fully machine washable, which is a huge practical advantage for parents. The Nectar Kids mattress uses OEKO-TEX Standard 100 certified fabrics and CertiPUR-US certified foams, and it is 100% fiberglass free. The trial is 365 nights.
Why parents buy it
- Two-sided design gives 5-6 years of usable life as the child grows
- Machine-washable cover handles spills and stains easily
- No chemical off-gassing reported during expansion
A practical limitation
- 8-inch thickness offers less support for heavy adults — this is a kids mattress, not suitable for regular adult use
Designed for: parents looking for a single mattress that can service a child from toddler to teenage years without buying a replacement.
Not for: adult primary bedrooms or anyone over about 150 lbs who needs a full-size bed for nightly use.
Understanding the Specs
Mattress Thickness (8 vs 10 vs 12 inches)
Thickness determines how much foam or spring structure sits between you and the foundation. An 8-inch mattress is enough for a child or a low-profile trundle. A 10-inch mattress works for a guest room or a budget-conscious adult setup. A 12-inch or 13-inch mattress packs more foam layers for better pressure relief, weight distribution, and durability — it is the thickness most adults prefer for daily use.
Construction: Memory Foam vs Hybrid vs Gel-Infused
Pure memory foam contours deeply and absorbs movement perfectly, but it can trap heat. Gel-infused foam (sometimes labeled NanoGel or cooling gel) mixes cooling particles into the foam to pull heat away. A hybrid mattress combines foam layers with pocket springs — the springs improve airflow, edge support, and bounce while the foam provides pressure relief. Your choice depends on whether you sleep hot and whether you share the bed with a partner.
