Jax Mattress shows up in local buying threads for one reason: value-priced hybrids that promise quick delivery. We tested five core models to see what the feel and build are like after real nights of sleep, not a quick showroom bounce.
We rotated sleep positions and sleepers, then scored support, pressure relief, cooling, motion isolation, responsiveness, and edge support. The lineup table gives the fast view, while the sections below add context; for broader shopping help, start with the Mattress Resource Hub, browse All Mattress Reviews, and see About Our Experts and About Dweva for our approach.

Main Jax Mattress Lineup
These are the five models we spent time on. Prices change by size and promos, so treat the ranges as a rough guide and the best hybrid mattresses guide can help set expectations.
| Mattress | Pros | Cons | Ideal For | Price* | Overall Score |
|---|---|---|---|---|---|
| 11" Tru Grid Mattress (2025) | Firm lift, quick response, cooler cover | Less cushion at shoulder, some bounce | Back/stomach sleepers, heavier builds | $$ | 4.5/5 |
| 12" Freedom Plush | More pressure relief, comfy surface feel | Edge is average, too soft for heavy stomach sleepers | Side sleepers, mixed positions | $$ | 4.4/5 |
| 12" Hybrid | Balanced feel, steadier edges, better for partners | Not a deep hug, cover can feel warm | Couples, back/side combo sleepers | $$ | 4.3/5 |
| 2 Sided Back Saver Plush | Flippable, sturdy core, value over time | More bounce, thinner cushion up top | Durability-focused shoppers, heavy sleepers | $$–$$$ | 4.2/5 |
| ASPEN Medium 14" Mattress | Even support, strong edge, stable medium feel | Heavy to move, not plush | Couples, back/side sleepers | $$–$$$ | 4.5/5 |
Testing Team Takeaways
Across the lineup, the feel leans coil-forward. You get quicker bounce and easier movement than you’d expect from all-foam beds.
- Tru Grid felt the firmest and most “lifted.” It worked best for back and stomach sleeping in our tests.
- Freedom Plush was the easiest model for side sleepers and lighter frames, with the softest top feel of the five.
- The 12" Hybrid landed in the middle. It handled couple testing better than the plush bed, while staying more forgiving than Tru Grid.
- Back Saver’s flippable build felt the most durable. The tradeoff is more bounce and less of a deep cradle.
- Aspen Medium was the most even from center to edge. It’s a solid “one bed for most people” option.

What We Tested and How We Tested It
We slept on each mattress for several nights, not just a single afternoon. Bedding and room temperature stayed consistent so we could compare changes in heat and support across models.
Scores come from a mix of hands-on checks and real sleep feedback, following our How We Test Mattresses process. When a model felt good for one body type but not another, we called that out instead of averaging it away.
- mattress firmness and overall feel (surface push-back and sink)
- mattress support and spinal alignment in back, side, and stomach positions
- pressure relief at shoulders and hips during longer side-sleep sessions
- mattress cooling and heat retention after the room warmed up
- motion isolation with partner movement and drop tests
- edge support while sitting and while sleeping near the perimeter
- responsiveness when changing positions
- build quality notes (noise, stitching, foam consistency)
Jax Mattress: Our Testing Experience
Below are the hands-on notes for each model, written from what we felt in the first few minutes and what held up (or didn’t) after full nights.
1. 11" Tru Grid Mattress
This is the firmest-feeling bed in the lineup. It stays more “on top” than “in” the mattress.
Our Testing Experience
The first thing we noticed was the push-back under the hips and lower back. On back and stomach nights, that lift stayed consistent and kept our midsections from sinking.
Side sleeping was more hit-or-miss. If you like a flatter surface, it feels stable. If you need a deeper shoulder pocket, it can feel too upright after an hour or two.
Changing positions felt easy. The surface rebounds quickly, which helps combination sleepers, but it also means you’ll feel more bounce than on slower foams.
Pros & Cons
| Pros | Cons |
|---|---|
| Strong, steady support • Easy to move on • Cooler, coil-forward feel • Good edge sitting stability | Not plush for shoulders • Noticeable bounce • Can feel firm for lighter sleepers |
Details
- Best for: back sleepers, stomach sleepers, and heavier builds.
- Feel: firm with quick response; more lift than hug.; for a harder feel, compare with best extra firm mattresses.
- Cooling: better than most foam-heavy beds thanks to airflow.
- If you share a bed, expect some motion transfer compared with thicker foams.
Review Score
| Metric | Score | Notes |
|---|---|---|
| Support | 4.8 | Kept hips lifted in back and stomach tests. |
| Pressure Relief | 4.0 | Shoulders got less cushioning than on softer models. |
| Cooling | 4.7 | Stayed cooler under heavier bedding. |
| Motion Isolation | 4.1 | Some bounce carries movement across the surface. |
| Responsiveness | 4.8 | Rebounds fast when changing positions. |
| Durability | 4.5 | Coil-forward build should hold shape well. |
2. 12" Freedom Plush
If Tru Grid feels too firm, Freedom Plush is the easiest “comfort-first” step down.
Our Testing Experience
The surface compresses more at the shoulders and hips, which helped our side-sleep sessions feel less sharp. The comfort is immediate, not something you have to “break in” for weeks.
Back sleeping felt balanced for average builds. For heavier stomach sleepers, the midsection can drift down more than we liked, especially on longer nights.
Motion control was decent for a plusher bed. You still feel some bounce, but it’s softer and more damped than the firmer models.
Pros & Cons
| Pros | Cons |
|---|---|
| Noticeably softer pressure relief • Good for side sleeping • Comfortable surface feel • Decent motion control | Not ideal for heavy stomach sleepers • Edges feel average • Less “lift” than Tru Grid |
Details
- Best for: side sleepers, lighter-to-average builds, and anyone who wants a gentler top feel.
- Feel: medium-plush with slower sink than memory foam-heavy beds.
- Cooling: feels cool at first touch; heat buildup depends on bedding.
- If you want more structure, consider the 12" Hybrid instead.
Review Score
| Metric | Score | Notes |
|---|---|---|
| Support | 4.2 | Solid for average builds; less stable for heavy stomach sleep. |
| Pressure Relief | 4.6 | Better shoulder and hip comfort than the firmer beds. |
| Cooling | 4.3 | Cool-touch cover helps, but softer foams can hold heat. |
| Motion Isolation | 4.4 | More damped movement than Tru Grid. |
| Responsiveness | 4.2 | Easy enough to move, but not as springy as Tru Grid. |
| Durability | 4.2 | Comfort layer should be watched for long-term body impressions. |
3. 12" Hybrid
This model sits between the firm Tru Grid and the softer Freedom Plush, both in feel and in who it fits.
Our Testing Experience
On night one, it felt “even” rather than dramatic. You get a supportive base with enough top give to keep side sleeping comfortable for most people.
For partner testing, it handled movement better than we expected from a coil bed. We still felt shifts, but the jolt was smaller and didn’t bounce as long.
Edge sleeping held up well. Lying near the perimeter felt more usable than the plush model, which matters for couples sharing a smaller size.
Pros & Cons
| Pros | Cons |
|---|---|
| Balanced comfort and support • Better edge use • More partner-friendly than expected • Easy position changes | Not the coziest plush feel • Some bounce remains • Cooling is average depending on bedding |
Details
- Best for: couples, combo sleepers, and back/side sleepers who want one safe choice.
- Feel: medium-firm with controlled rebound.
- Cooling: adequate for most rooms; hot sleepers may want a dedicated cooling pick.
- If you want the softest pressure relief, Freedom Plush still wins.
Review Score
| Metric | Score | Notes |
|---|---|---|
| Support | 4.5 | Even support across the center and edges. |
| Pressure Relief | 4.3 | Enough give for shoulders without losing stability. |
| Cooling | 4.2 | Breathable, but not the coolest in this lineup. |
| Motion Isolation | 4.5 | Partner movement is muted for a coil bed. |
| Responsiveness | 4.6 | Quick, controlled rebound helps combination sleepers. |
| Durability | 4.3 | Balanced build should hold up for typical use. |
4. 2 Sided Back Saver Plush
This is the outlier: a two-sided mattress that’s built to be flipped and used both ways.
Our Testing Experience
The feel is less “pillowy” than the name suggests. It’s supportive first, with a thinner comfort layer that keeps you from sinking too deep.
Flipping changes the surface character more than we expected. One side felt slightly firmer and snappier, while the other felt a bit more forgiving at the hip.
The tradeoff for durability is bounce. If you’re sensitive to movement, you’ll want to pay attention to how your partner turns at night.
Pros & Cons
| Pros | Cons |
|---|---|
| Two usable sides • Strong midsection support • Good long-term value • Airy coil feel | More motion transfer • Less deep cushioning • Heavier to rotate or flip |
Details
- Best for: heavier sleepers (see best mattresses for heavy people), stomach sleepers, and anyone who wants a longer-lasting build.
- Feel: supportive with noticeable bounce; comfort layer is thinner than on plush hybrids.
- Maintenance: flipping and rotating helps even out wear.
- If you want a softer cradle, look at Freedom Plush.
Review Score
| Metric | Score | Notes |
|---|---|---|
| Support | 4.7 | Stayed stable under heavier bodies and stomach sleep. |
| Pressure Relief | 4.0 | Less cushion for shoulders than the softer models. |
| Cooling | 4.5 | Airflow from the coil-forward build helps. |
| Motion Isolation | 3.9 | Movement carries more than on pocketed-coil hybrids. |
| Responsiveness | 4.7 | Fast rebound makes turning easy. |
| Durability | 4.6 | Flippable design should extend usable life. |
5. ASPEN Medium 14" Mattress
Aspen Medium is the most balanced “do-it-all” option we tested in the Jax group.
Our Testing Experience
The taller profile changes the feel. It has a steadier, more substantial base, and the edge holds up better when you sit or sleep near the side.
Side sleeping felt comfortable without turning into a deep sink. The surface gives enough at the shoulder, then pushes back before the spine tilts.
For couples, the combination of edge stability and decent motion control made the mattress feel larger than it is, especially in queen size.
Pros & Cons
| Pros | Cons |
|---|---|
| Even feel across the surface • Strong edge support • Good all-around comfort • Better for couples | Not a plush hug • Heavier to move • Bounce is still present |
Details
- Best for: couples, back/side sleepers, and shoppers who want a stable medium feel.
- Feel: true medium-firm with controlled spring.
- Cooling: generally good, helped by airflow and the taller build.
- If you want the firmest support, Tru Grid still has more lift.
Review Score
| Metric | Score | Notes |
|---|---|---|
| Support | 4.6 | Kept alignment steady across positions. |
| Pressure Relief | 4.3 | Enough give for shoulders without excess sink. |
| Cooling | 4.4 | Breathable design and airflow work well. |
| Motion Isolation | 4.4 | Partner movement is reduced for a coil bed. |
| Responsiveness | 4.5 | Quick but not twitchy rebound. |
| Durability | 4.4 | Edge reinforcement helps long-term shape. |

How to Choose the Jax Mattress?
Start with your primary sleep position, then adjust for heat, partner movement, and body weight. If you’re stuck between two models, pick the one that matches the problem you’re trying to solve (pressure relief vs lift vs motion control).
- Side sleepers: prioritize pressure relief (see best mattresses for side sleepers). Freedom Plush is the softest top feel; Aspen Medium is the more balanced alternative.
- Back sleepers: aim for even lift without feeling “stuck” (see best mattresses for back pain). Tru Grid and Aspen Medium were strongest here.
- Stomach sleepers: lean firmer (see best mattresses for stomach sleepers). Tru Grid and Back Saver kept hips from sinking more consistently.
- Hot sleepers: prefer coil airflow and lighter comfort layers (see best mattresses for hot sleepers). Tru Grid and Back Saver ran cooler in our testing.
- Couples: look for edge support and motion isolation (see best mattresses for couples). Aspen Medium and the 12" Hybrid performed best overall.
If you’re deciding mainly by feel, think in plain terms: firmer beds give lift and easier movement, while plusher tops reduce pressure points; the comparisons in Firm vs Soft Mattress, Medium-Firm vs Soft Mattress, and Firm vs Medium-Firm Mattress can help you map that feel. A “medium” hybrid often lands in the best compromise for shared beds, and the explainer pages Memory Foam vs Hybrid Mattress, Latex vs Hybrid Mattresses, Hybrid vs Innerspring Mattress, and Innerspring vs Pocket Coil Mattress help clarify the build differences.
Limitations
We focused on the core Jax lineup and tested in typical bedroom conditions. Long-term durability is an outlook based on construction and short-term wear, not a multi-year lab study. If you’re highly sensitive to motion or need specialty medical guidance, consider that before buying any coil-forward mattress; if you want a more traditional feel, compare with the best innerspring mattresses list.

FAQs
Are Jax Mattress products good quality compared with big national brands?
Build quality depends on the specific model, but the lineup we tested is coil-forward and fairly straightforward. The value is strongest when you want a hybrid feel without paying for a premium label.
Which Jax Mattress is best for side sleepers?
Freedom Plush gave the most shoulder and hip relief in our side-sleep sessions. If you want a steadier edge or share the bed, Aspen Medium is the next best option.
Which Jax Mattress is best for back pain?
We can’t speak to medical outcomes, but for back sleeping comfort we looked for steady lift and neutral alignment. Tru Grid and Aspen Medium were the most consistently supportive in our tests.
How do Jax Mattress beds perform for hot sleepers?
The cooler-feeling options were the more coil-forward, less foam-heavy builds. Tru Grid and Back Saver had the best airflow feel, while Freedom Plush held heat a bit more depending on bedding.
Which Jax Mattress works best for couples?
Aspen Medium and the 12" Hybrid handled partner movement and edge use better than the plush model. If one partner is very light and the other is heavier, Aspen Medium felt the most even.
Do Jax Mattress models have strong edge support?
Edge support varies. Aspen Medium had the most stable perimeter, while Freedom Plush felt softer near the edge. If you often sit on the side of the bed, favor the sturdier builds.
How do these mattresses arrive and how long before sleeping on them?
Most modern mattresses arrive compressed. Once unboxed, give the bed time to expand and air out, then check the seller’s guidance for how long to wait before sleeping on it.
