Giantex takes a practical approach aimed at budget mattress shoppers. The two current options in this review serve very different needs: the 8-inch Air Foam works as a conventional bed for lighter-to-average-weight sleepers, while the roll-up floor futon is built for guests, dorm rooms, and spaces that need to stay flexible. The Air Foam was easier to move on and more supportive through the middle. The futon was simpler to store, but its comfort depended heavily on the surface underneath it.
Which Giantex Mattress Stands Out?
| Mattress | Overall Score | Pros | Cons | Ideal For |
|---|---|---|---|---|
| Giantex 8-Inch Air Foam Mattress | 4.0 | Responsive feel; cooler surface; stable center | Limited contour; average motion control; soft edges | Back sleepers; combination sleepers; guest rooms |
| Giantex Japanese Floor Futon Mattress | 3.6 | Easy storage; washable cover; versatile floor use | Light pressure relief; base-dependent comfort; little edge structure | Dorms; sleepovers; flexible floor sleeping |
Our Bottom Line
Giantex 8-Inch Air Foam Mattress: This is the better choice for regular bed use. Its responsive foam makes turning easy, and the center stays level enough for back and combination sleepers under about 200 pounds. It is less convincing for strict side sleepers who need deep shoulder cushioning, couples who are easily disturbed, or anyone who sits on the edge every day.
Giantex Japanese Floor Futon Mattress: Choose the futon when storage and flexibility matter more than deep support. It rolls away neatly, includes useful storage accessories, and works well for an occasional guest or secondary sleeping space. It is not a substitute for a structured mattress if you have sensitive shoulders or hips, sleep on a hard floor, or need dependable nightly support.

How We Evaluated These Mattresses
Each mattress followed the same mattress test routine: overnight back and side sleeping, a 30-minute temperature check, repeated position changes, motion tests, and edge or perimeter loading. Marcus (6'1", 230 pounds) focused on support depth and heat, Mia (5'4", 125 pounds) tracked shoulder and hip comfort, and Carlos (5'11", 175 pounds) checked back alignment and ease of movement. Support, cooling, pressure relief, motion isolation, responsiveness, edge support, and durability all use the same 5-point scale.
Giantex Mattress: Our Testing Experience
Giantex 8-Inch Air Foam
Our Testing Experience
The Air Foam expanded to 7.9 inches and registered medium-firm in our firmness assessment at 6.3 out of 10. On his back, Carlos stayed level through the hips without the slow, deep sink common to memory foam. Turning from back to side took little effort, and the surface recovered to 90% of its height in 1.8 seconds after the load was removed. Mia found enough cushioning for short side-sleeping stretches, but the pressure reading became more noticeable at her shoulder during a full night.
Heat buildup was modest for an all-foam mattress. In our 30-minute cooling check, the surface rose 5.6°F and began cooling soon after the tester got up. Marcus still felt properly supported through the center, although the perimeter compressed more sharply: a 150-pound load produced 3.1 inches of compression near the edge versus 2.0 inches at the center. That difference was easy to feel when sitting down, even though the mattress remained stable while lying flat.
What we liked
- Quick recovery makes position changes noticeably easier than on slow-response memory foam.
- The center holds the hips level for lighter-to-average-weight back and combination sleepers.
- Temperature rise stayed modest during the 30-minute heat check.
Who it is best for
- Back and combination sleepers who prefer a medium-firm, low-sink surface.
- Hotter sleepers who want a basic foam mattress without a heavy body-hugging feel.
- Guest rooms and budget bedrooms where an 8-inch profile is enough.
Where it falls short
- Strict side sleepers may want more cushioning at the shoulders and hips.
- Heavy movement travels across the bed more than it does on dense memory foam.
- The perimeter compresses too much for people who regularly sit or sleep at the edge.
Pros & Cons
| Pros | Cons |
|---|---|
| Responsive surface makes turning easy | Limited contour for shoulders and hips |
| Retains less heat than denser foam | Only moderate motion isolation |
| Nonslip bottom keeps the mattress steady | Perimeter compresses under seated weight |

| Overall | 4.0 | The stronger all-around option for regular bed use. |
Giantex Roll-Up Floor Futon
Our Testing Experience
The futon reached 3.8 inches after its rebound period and changed character with the floor beneath it. It felt firm at 6.8 out of 10 on hard flooring, where Mia noticed shoulder pressure within the first hour. On carpet, the feel eased to 5.9 out of 10, and a 44-pound load sank 1.1 inches. Carlos liked the flatter surface for back sleeping, but our support check showed there was not enough depth to cushion a full night on the side.
It handled casual use well. The surface temperature rose 6.2°F over 30 minutes, which felt reasonably breathable rather than actively cool. We rolled and unrolled the futon 30 times; the stitching stayed intact, the fill remained even, and no persistent lumps appeared. Storage was straightforward with the two securing bands and carry bag. Still, this is a floor pad rather than a structured bed, so the low edge score reflects the design—not a failed reinforced border.
What we liked
- The futon rolls into its carry bag and is much easier to store than a rigid guest mattress.
- The removable washable cover and separate dustproof cover simplify routine care.
- The quilted surface stayed even through repeated rolling and unrolling.
Who it is best for
- Overnight guests, dorm rooms, and multipurpose spaces that need the floor back during the day.
- Back sleepers who want light cushioning without the deep sink of memory foam.
- Occasional camping setups where compact storage matters most.
Where it falls short
- Hard floors transmit pressure quickly, especially at the shoulder and hip.
- The 4-inch profile is not supportive enough for most heavier adults over a full night.
- It has no meaningful perimeter for sitting or sleeping at the edge.
Pros & Cons
| Pros | Cons |
|---|---|
| Roll-up design is easy to store | Provides less pressure relief than a bed mattress |
| Washable cover makes cleanup simpler | Comfort changes with the surface underneath |
| Useful for sleeping, lounging, or play | No reinforced edge for sitting |

Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 3.4 | Even cushioning, but no structured support core. |
| Cooling | 3.8 | Breathable enough for occasional use. |
| Pressure Relief | 3.3 | Acceptable on carpet; noticeably firmer on hard flooring. |
| Motion Isolation | 3.7 | Calm for solo use, though movement still crosses the pad. |
| Responsiveness | 4.0 | Easy to turn on without a deep foam sink. |
| Edge Support | 3.0 | The floor-pad design has no reinforced perimeter. |
| Durability | 3.9 | Stitching and fill stayed even through 30 roll cycles. |
| Overall | 3.6 | A useful occasional floor bed, not a primary mattress. |
How the Two Mattresses Scored
| Mattress | Overall | Support | Pressure Relief | Cooling | Motion Isolation | Durability | Responsiveness | Edge Support |
|---|---|---|---|---|---|---|---|---|
| Giantex 8-Inch Air Foam Mattress | 4.0 | 4.2 | 3.8 | 4.1 | 3.7 | 4.0 | 4.3 | 3.6 |
| Giantex Japanese Floor Futon Mattress | 3.6 | 3.4 | 3.3 | 3.8 | 3.7 | 3.9 | 4.0 | 3.0 |
The Air Foam finished ahead because it offered more support, better pressure distribution, and a usable perimeter while remaining easy to move on. The futon stayed close in cooling, responsiveness, and observed wear, but its thin floor design limited support and pressure relief. These scores compare performance under the same test routine; they do not make the futon a direct replacement for a bed mattress.
Which Giantex Mattress Should You Choose?
Start with the room and how often the mattress will be used. Choose the 8-inch Air Foam for a guest bed or regular bed used by a lighter-to-average-weight back or combination sleeper; a body-weight mattress guide can help if you are near the support limit. Its medium-firm feel and quick recovery are easier to live with every night, although strict side sleepers may need more depth. Choose the roll-up futon when storage comes first and sleeping is occasional. Put it over carpet, a rug pad, or a thin tatami-style mattress foundation; on bare hard flooring, its 4-inch cushioning feels substantially firmer. Our guide to mattress thickness explains why the two profiles feel so different.
Where Each Mattress Falls Short
Giantex 8-Inch Air Foam Mattress
- Perimeter compresses more than the center.
- Side sleepers get only moderate shoulder and hip contouring.
- Heavy partner movement remains noticeable.
Giantex Japanese Floor Futon Mattress
- Hard floors make pressure points more obvious.
- The 4-inch profile lacks support depth for heavier adults.
- The design provides no practical edge for sitting.
How Giantex Compares With Alternatives
Why choose Giantex
The Air Foam offers a responsive, low-profile bed at the budget end of the market, while the floor futon prioritizes washable, compact storage. Both are simple products with clear use cases. Neither is the right choice if you want deep contouring, a reinforced perimeter, or a thick support system.
Alternatives to consider
Best Price Mattress Airflow 8-Inch: This is the closest like-for-like alternative to the Air Foam in the under-$500 mattress category. Its three-layer memory-foam build contours more closely, but it also responds more slowly. Availability varies by size, so it works best as a price comparison rather than a guaranteed substitute.
Zinus Original Green Tea Memory Foam: The current 10-inch model is a meaningful step up in depth and pressure relief, especially for side sleepers. It costs considerably more than the Giantex Air Foam and has a stronger body-hugging feel, so it is better for cushioning than for quick position changes.
Linenspa 8-Inch Memory Foam Hybrid: The coils add lift and a more familiar mattress feel for back and combination sleepers. It should feel sturdier than the Air Foam around the perimeter, but it is bouncier and may transfer more motion. Direct stock is inconsistent, so check the exact retailer and size before relying on it.
Milliard 6-Inch Tri-Fold: Milliard's current 6-inch folding model provides more cushioning than the 4-inch Giantex futon and is the better portable choice for adults staying several nights. The trade-offs are a higher price, a larger folded footprint, and more weight to move.
How to Get Better Results From a Giantex Mattress
- Let a compressed mattress finish expanding before judging its height or comfort.
- Place the futon on carpet, a rug pad, or a thin tatami-style base to reduce pressure from hard flooring.
- Use breathable sheets and a lightweight protector if you sleep warm.
- Rotate the Air Foam from head to foot every few months to spread wear more evenly.
- Avoid sitting in the same spot along the Air Foam perimeter every day.
- Use a pillow height that keeps your neck level with the mattress's relatively shallow contour.
- Roll the futon only after it is clean and fully dry so moisture is not trapped in the storage bag.
- Check platform-bed slat spacing before placing the Air Foam on an open frame.
Giantex Mattress FAQs
Is the 8-inch Giantex Air Foam thick enough for everyday adult use?
It can work for lighter-to-average-weight back and combination sleepers who like a medium-firm surface. Heavier adults and strict side sleepers are more likely to need a less restrictive profile with deeper support and pressure relief.
Which retained Giantex model isolates motion best?
Both scored 3.7 out of 5, but neither is a standout among the best mattresses for couples. The Air Foam is the more practical shared bed because it has a structured sleeping surface. The futon is calmer when used solo, but movement still travels across its thin quilted body.
What should go under the roll-up futon for better comfort?
Use carpet, a thick rug pad, a foam play mat, or a thin tatami-style pad. A slightly cushioned base reduces pressure at the shoulders and hips and keeps the feel of hard flooring from coming through.
