On this page (4 sections)
The best medium firm mattress full size for most shoppers is the Signature Design by Ashley Chime 12 Inch, a hybrid with gel memory foam lumbar support and wrapped coils. For a slimmer foam mattress, consider MLILY or EGOHOME; for a taller all-foam feel, look at Zinus Green Tea.
A full mattress can suit a single sleeper, guest room or smaller bedroom where a queen would take too much floor space. These options vary in height, materials and stated firmness, so choose based on how much cushioning you want and what your bed frame can support.
If you are still deciding which mattress to buy, start with your size, preferred feel and frame. Our guide to firm vs soft mattress explains how a mattress feel can affect comfort, while firm mattress vs medium firm compares those two common choices.

How we chose these medium firm full mattresses
We compared the listed dimensions, construction, feel, materials and setup notes against what someone shopping for a medium firm full mattress is likely to need. Our score weighs specs, features and buyer feedback against what you're shopping for.
Some mattresses here are labeled medium rather than medium firm. We kept them in the comparison because shoppers looking for a balanced feel may consider them, but we call out that difference so you can make an informed choice.
A full mattress is commonly around 54 x 75 in, as reflected in several picks. Confirm your frame's interior dimensions before ordering, especially if it uses a tight-fitting platform or has a guardrail.

The best medium firm mattress full size picks
The Ashley Chime is the strongest match for shoppers who specifically want a medium firm hybrid, while the foam options make it easier to choose a slimmer or taller profile. These nine picks are listed from highest score to lowest.
Signature Design by Ashley Chime 12 Inch: Best for hybrid support
- 12-inch hybrid construction
- Gel memory foam lumbar support
- Wrapped coils
- CertiPUR-US certified foam
A 12-inch hybrid pairs gel memory foam with wrapped coils for a responsive feel. It suits shoppers who want a medium firm full mattress with both foam cushioning and coil support.
Pros
- Hybrid foam and coil construction
- Gel memory foam targets the lower back
- Compatible with most bed frames and adjustable bases
Cons
- Heavier than the foam-only options here
- 12-inch height may need deeper fitted sheets
The Ashley Chime combines gel memory foam and wrapped coils in a 12-inch full mattress. Its .75-inch high-density gel memory foam targets the lower back, and the pocketed coils aim to reduce motion transfer while adding edge support.
This hybrid may suit someone who wants more response than an all-foam mattress provides. It is compatible with most bed frames and adjustable bases, and Ashley describes its feel as medium firm.
At 12 inches tall, it sits higher than the 8-inch options below. Check your fitted sheet depth and total bed height, particularly if the mattress will go on a tall foundation.
Choose it if you want foam cushioning with a coil support system in one mattress. Its listed full dimensions are 53 x 74.5 x 12 in, so compare those with your frame before making a choice.
MLILY 8 Inch Full Mattress: Best for a slimmer foam profile
- 8-inch memory foam
- Green tea gel foam
- Fiberglass-free inner cover
- CertiPUR-US certified foam
This 8-inch foam mattress has a gel-infused comfort layer and a fiberglass-free inner cover. Its slimmer profile can suit a bunk bed, daybed or room where a taller mattress is not needed.
Pros
- 8-inch profile
- Gel-infused foam
- Expands within 2 hours
Cons
- Foam-only feel lacks wrapped coils
- A shorter profile may feel too low for some bed setups
MLILY suits a room or bed frame where an 8-inch mattress profile works better than a taller one. Its construction includes 2 inches of green tea gel foam over 6 inches of memory foam, with a medium firm feel.
The gel-infused foam is designed to help dissipate heat while retaining a body-conforming feel. MLILY also describes the inner cover as fiberglass-free and says the foam is CertiPUR-US certified.
This is a foam-only mattress, so its feel differs from the Ashley Chime hybrid. It expands within 2 hours, which can make setup simpler if you are preparing a room on a short schedule.
Choose MLILY if you want an 8-inch medium firm full mattress with a gel foam layer. Check the finished height against your frame and the level of cushioning you prefer.
Zinus Memory Foam 12 Inch Green Tea: Best for a taller foam mattress
- 12-inch memory foam
- Green tea and charcoal infused foam
- Pressure-relieving comfort foam
- CertiPUR-US certified foam
The 12-inch all-foam build offers a taller profile with memory foam and pressure-relieving comfort foam. Green tea and charcoal are infused into the foam.
Pros
- 12-inch height
- Memory foam contours to the body
- Compatible with adjustable bases, box springs and platform beds
Cons
- Foam may feel less springy than a hybrid
- A taller mattress can change bed height
Zinus Green Tea gives you a 12-inch all-foam profile with memory foam and pressure-relieving comfort foam. It is the tallest foam-only option among these picks.
Green tea and charcoal are infused into the memory foam. Zinus describes the mattress as medium firm, and its compatibility information includes adjustable bases, box springs and platform beds.
A taller foam mattress can change how high your bed sits, so consider the frame and your fitted sheets together. If you want to know whether a firmer mattress can flex with a powered base, read can a firm mattress bend on an adjustable base.
Choose this mattress if you want a taller memory foam option with a medium firm feel. The 12-inch height and listed base compatibility make it useful to compare against the hybrid picks.
EGOHOME Full Size Memory Foam Mattress: Best for an 8-inch gel foam option
- 8-inch memory foam
- Green tea gel infusion
- Breathable bubble-hole structure
- CertiPUR-US certified foam
This 8-inch full mattress uses memory foam with green tea gel and a breathable structure. It is a practical match for shoppers who want a compact foam profile with pressure-relieving cushioning.
Pros
- 8-inch height
- Green tea gel infusion
- 10-year warranty
Cons
- No coil layer
- Foam feel may not suit people who prefer a buoyant surface
EGOHOME is another 8-inch medium firm foam mattress, with green tea gel and a breathable bubble-hole structure. The foam is designed to adapt as your sleeping posture changes and distribute body pressure.
Its compact height may suit a bed frame where a 12-inch mattress would sit too high. EGOHOME also states that the mattress has a 10-year warranty, and its CertiPUR-US certification is listed for the foam.
There are no coils in this build, so expect a foam feel rather than the more responsive sensation of a hybrid. Its 75 x 54 in dimensions match a common full mattress footprint.
Choose EGOHOME for an 8-inch memory foam option with a gel infusion and stated medium firm feel. It is a close alternative to MLILY if you are comparing slimmer foam beds.
GAESTE Full Size 8 Inch Cooling Gel: Best for a medium feel
- 8-inch gel memory foam
- Cooling gel infusion
- CertiPUR-US certified foam
- OEKO-TEX certified cover
GAESTE describes this mattress as medium feel, so it is worth considering if you want a balanced surface but do not need a firm medium-firm label. Its gel foam is designed to manage heat.
Pros
- Cooling gel memory foam
- 8-inch profile
- Compatible with most full size frames
Cons
- Described as medium rather than medium firm
- Allow up to 72 hours for full expansion
GAESTE is for buyers who want a medium feel rather than a clearly medium firm label. Its 8-inch construction uses gel-infused memory foam, which is designed to manage heat and contour to the body.
The mattress is compressed and rolled for setup. GAESTE advises allowing 72 hours for full expansion, so account for that wait when preparing a bedroom.
Its medium feel makes it different from the medium firm options above. If you prefer a firmer queen, compare firm queen mattresses.
If you like a balanced surface but worry that medium firm could feel too rigid, this may be worth comparing.
Choose GAESTE if you prefer an 8-inch foam mattress with a medium feel and cooling gel. If you specifically want medium firm, compare its label carefully with Ashley, MLILY, Zinus or LIFEMENT.
PurrJoys Full Mattress: Best for pocketed coil cushioning
- 12-inch hybrid construction
- Memory foam and pocket springs
- CertiPUR-US certified
- Fits box springs, floors, slatted bases and flat platforms
This 12-inch hybrid combines memory foam with individually encased pocket springs. Its stated feel is medium, so it may suit shoppers who want cushioning and coils more than a distinctly firm surface.
Pros
- Pocket springs move independently
- 12-inch height
- Works with several frame types
Cons
- Described as medium rather than medium firm
- Allow 72 hours for full expansion
PurrJoys pairs memory foam with individually encased pocket springs in a 12-inch hybrid. The independent coils are designed to follow body contours and reduce movement transfer.
Its listed feel is medium, so it is not as direct a match for this roundup's medium firm search as the first four picks. Still, it may suit shoppers who want a cushioned hybrid and are open to a medium feel.
The mattress fits several foundation types, including box springs, slatted bases and flat platforms. PurrJoys says it fully expands within 72 hours, despite restoring its shape soon after unpacking.
Choose it if the combination of foam and pocket springs matters more than a medium firm label. If firmness is your first filter, compare it with the Ashley Chime and the medium firm foam models.
Zinus 8 Inch Full Cooling Essential Memory: Best for cooling foam and frame flexibility
- 8-inch memory foam
- Cooling gel memory foam
- Fiberglass-free construction
- Compatible with adjustable bases
This Zinus has cooling gel memory foam, a medium feel and an 8-inch profile. It supports buyers who want a foam mattress for an existing platform, slatted frame or adjustable base.
Pros
- Cooling gel memory foam
- Fiberglass-free construction
- Works with several frame types
Cons
- Medium feel rather than medium firm
- Allow 24 to 72 hours for full expansion
Zinus Cooling Essential is an 8-inch memory foam mattress with a medium feel. Cooling gel memory foam and a breathable cover are intended to make the surface more comfortable for warm sleepers.
It is compatible with platform beds, box springs, slatted frames and adjustable bases. Zinus describes the construction as fiberglass-free and says its foam is CertiPUR-US certified.
The medium feel is worth separating from medium firm when making your choice. This mattress can suit someone who wants a less firm sensation and a shorter profile.
Choose it for cooling gel foam and broad frame compatibility. If you need a firmer feel, compare it with the 8-inch medium firm MLILY or EGOHOME instead.
LIFEMENT Full Size Mattress: Best for graphite cooling foam
- 8-inch memory foam
- Graphite-infused top layer
- Three-layer support system
- CertiPUR-US certified foam
LIFEMENT uses an 8-inch, three-layer foam design with graphite-infused memory foam at the top. It is a medium firm option for buyers interested in a cooling surface and motion absorption.
Pros
- Three-layer construction
- Graphite-infused memory foam
- Removable cover
Cons
- Expansion time can be up to 72 hours
- Foam-only feel
LIFEMENT combines graphite-infused memory foam with a three-layer support system in an 8-inch full mattress. Its stated medium firm feel makes it one of the closer matches for this search.
The top layer is open-cell graphite memory foam, while the other layers provide transition and base support. LIFEMENT says the design helps move heat away and absorb motion.
It is a foam-only mattress, so it will not give the spring response of a hybrid. The cover is removable, which can be useful when planning mattress care.
Choose LIFEMENT if you want a medium firm 8-inch mattress with graphite foam and a layered build. Allow up to 72 hours for full expansion.
MOLPHIT Double Mattress: Best for zoned coil support
- 12-inch hybrid construction
- 7-zone pocket spring system
- Memory foam and individually wrapped coils
- Medium firm feel
MOLPHIT combines memory foam with a 7-zone pocket spring system in a 12-inch hybrid. Its materials and zoned design may appeal to shoppers seeking targeted support, though the stated feel is medium.
Pros
- 7-zone pocket spring system
- Individually wrapped coils
- 12-inch profile
Cons
- Described as medium rather than medium firm
- Allow up to 76 hours for expansion
MOLPHIT adds 7-zone pocket springs beneath memory foam in a 12-inch hybrid. Its coil system is designed to cushion different areas of the body and limit motion transfer.
The stated feel is medium, not medium firm, so consider it if you want a somewhat softer balance or are comparing multiple hybrid styles. Its 12-inch height is similar to the Ashley Chime and PurrJoys.
MOLPHIT advises giving the mattress up to 76 hours to expand. Make space for the mattress to rest while it reaches its full shape.
Choose this model if the zoned coil layout is a priority and you are comfortable with a medium feel. For a more direct medium firm fit, the Ashley Chime is the stronger hybrid choice in this group.
How to choose a full mattress with a medium firm feel
A medium firm mattress should balance surface cushioning with support, but the label alone cannot tell you how it will feel in your bedroom. Construction, body weight and sleep position all affect how much you sink into the top layers.
Which mattress height fits your full bed?
An 8-inch mattress may keep your bed lower and suit a bunk, guest room or frame with limited clearance. A 12-inch mattress adds height and may change how easy it is to get in and out of bed.
Measure your frame and consider the foundation beneath it. If your mattress sits on an adjustable base, also check the base's compatibility guidance and flexibility needs.
Should you choose foam or a hybrid?
Foam models contour around the body and can absorb movement across the surface. Hybrids combine foam with coils, which can give a more responsive feel.
For a medium firm hybrid, the Ashley Chime is the clearest match here. The PurrJoys and MOLPHIT also use coils, but both are described as medium.
What should you check before ordering?
Compare the mattress dimensions with your frame, then check the finished height with your foundation and fitted sheets. Full mattresses in this selection are listed around 54 x 75 in, with small variations in the Ashley Chime dimensions.
Also consider delivery and expansion instructions. Several picks arrive compressed, and the time they need to expand ranges from a couple of hours to more than 3 days.
If you are furnishing a larger bed, compare our best medium firm mattress queen picks. For a broader set of sizes and materials, see best medium firm mattress.
Which medium firm full mattress should you choose?
Choose the Ashley Chime if you want a medium firm hybrid with wrapped coils and gel memory foam. Pick MLILY or EGOHOME for an 8-inch foam profile, Zinus Green Tea for a 12-inch all-foam build, or LIFEMENT for graphite-infused medium firm foam.
If a medium feel sounds more comfortable than medium firm, compare GAESTE, PurrJoys and MOLPHIT, while keeping their different constructions in mind. For ongoing pain or sleep problems, talk with a health care professional before relying on a mattress change.
For a full-size bed, the best medium firm mattress depends on your preferred height, materials and feel. Start with those fit details, then compare the specific features that matter to your setup.

Frequently asked questions
What does medium firm mean in a full mattress?
Medium firm usually describes a feel between plush and firm, with cushioning at the surface and a more supportive sensation underneath. Firmness is subjective, so body weight, sleep position and mattress materials can change how the same label feels.
Compare the listed feel with the mattress height and construction before choosing.
Is a full size mattress big enough for two people?
A full mattress measures about 54 x 75 in in these picks. That gives two people less width per person than a queen, so it may work best for a single sleeper or a pair comfortable sharing a compact sleep surface.
Measure your room and consider how much space each sleeper needs.
Should I choose a foam or hybrid medium firm mattress?
Choose foam if you want a mattress built from layers that contour to your shape. A hybrid adds coils beneath foam, which can create a more responsive feel.
The Ashley Chime and PurrJoys are hybrids here.
Compare their listed feel and height, since PurrJoys is described as medium.
Can a medium firm mattress go on an adjustable base?
Some mattresses are compatible with adjustable bases, but compatibility depends on the specific model and base. The Ashley Chime, Zinus Green Tea 12 Inch and Zinus Cooling Essential list adjustable base compatibility.
Check the base's size and weight limits, then read what mattresses work with adjustable bases before pairing them.
How long should a boxed mattress expand?
Expansion time varies by mattress. MLILY says its mattress expands within 2 hours, while GAESTE and PurrJoys advise allowing up to 72 hours for full expansion.
Follow the instructions for the model you choose, and plan setup with its stated wait time in mind.
