The WinkBeds GravityLux Mattress is an all-foam bed that uses a more responsive style of memory foam plus targeted support. It comes in three firmness options—Soft, Medium, and Firm—so side sleepers, back sleepers, and combination sleepers can chase pressure relief without the deep “swallowed” feeling some foams create. If you’re comparing a few models, our full mattress review library can help narrow the field.

Product overview
| Mattress | Overall Score | Pros | Cons | Ideal For |
|---|---|---|---|---|
| WinkBeds GravityLux Mattress | 4.3/5.0 | Balanced contouring with pushback support, strong motion isolation, three firmness options | Foam edges aren’t coil-firm, limited bounce compared with latex or springs | Couples, combo sleepers, pressure-sensitive side sleepers who want options |
Final verdict
In our testing, the GravityLux delivered a “modern foam” feel: noticeable contouring up top, followed by firmer pushback through the midsection that helped keep my hips from drifting out of line. The Medium felt the most broadly workable in our room. Soft leaned more pressure-relieving, while Firm kept you more on top of the bed.
-
Who It’s For
- Couples who want quiet, low-motion sleep
- Back/side combo sleepers who want contouring with structure
- People who like foam but don’t want to feel “stuck”
-
Who It’s Not For
- Strict stomach sleepers who need an ultra-flat, very firm surface
- Anyone chasing a springy, latex-like bounce
- People who sit on the edge often and want maximum rigidity
Test method
Our testing team slept on the GravityLux and ran firmness-specific check-ins, then re-tested after the break-in period settled. In our repeatable routines, we scored Support, Cooling, Pressure Relief, Motion Isolation, Responsiveness, Edge Support, and Durability using posture photos for alignment, partner-disturbance drills, heat buildup notes, edge sit/stand tests, and “turn-and-reset” timing for mobility.
Our experience
I used the GravityLux Medium as my main sleep surface because it’s positioned as the “just right” option—and it felt that way in real nights. On my side, the top layers let my shoulder settle without a sharp pressure point. When I rolled onto my back, the mattress didn’t keep sinking through the middle, so my hips felt supported instead of “hammocked.”
Marcus (6'1", ~230 lbs) noticed the foam stayed supportive under his hips and liked how quickly the surface calmed down after position changes. Jenna (5'7", ~160 lbs) and Ethan (6'0", ~185–190 lbs) focused on partner disturbance; in our drills and overnight use, movement stayed localized, so late-night get-ups felt less like a whole-bed event. Dr. Adrian Walker, MD, emphasized that our best nights lined up with the mattress holding a neutral midline while still letting pressure points decompress, especially for side sleeping.
-
What we liked
- Stable lumbar-and-hip feel without turning the surface into a board
- Partner movement stayed mostly on the side where it started
- Medium hit a practical “hug + pushback” middle ground
-
Who it is best for
- Side/back combo sleepers who change positions a few times per night
- Couples sensitive to motion transfer
- Foam fans who still want some responsiveness
-
Where it falls short
- Edges compress more than a good hybrid when sitting to get dressed
- It’s adaptive, but it’s still foam—bounce is limited
- Firm can feel too upright for lighter side sleepers
Pros & cons
| Pros | Cons |
|---|---|
| Strong pressure relief with a more supported foam feel | Edge support is good for foam, not hybrid-level |
| Three firmness choices to match sleep style | Less bounce than latex or coils |
| Excellent motion isolation for couples | Some sleepers may notice initial foam smell |
| Targeted midsection support helps alignment | Many stomach sleepers will prefer a firmer, flatter hybrid |

Review score
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.6 | In our posture checks, the zoned-style pushback kept hips and lower back from drifting. |
| Cooling | 4.2 | It ran cooler than many foams we’ve tested, helped by the cover and heat-dispersing build, but it’s still foam. |
| Pressure Relief | 4.3 | Medium balanced shoulder/hip give with structure; Soft goes further for pressure sensitivity. |
| Motion Isolation | 4.5 | Partner movement stayed localized in our drills and normal nights. |
| Responsiveness | 4.0 | Easier to move on than slow, traditional memory foam, but not springy. |
| Edge Support | 4.1 | Stable for foam when sleeping near the edge; sitting compression is noticeable. |
| Durability | 4.3 | A high-density core plus the long-term warranty structure point to solid longevity. |
Overall Score: 4.3/5.0
How to choose
Choose the GravityLux based on (1) how much sink you like, (2) how often you change positions, and (3) how sensitive you are at the shoulders and hips. Soft favors lighter-to-average side sleepers who want extra cushioning. Medium is the safest fit for mixed positions. Firm is best if you want to stay more on the mattress.
If you’re a hot sleeper who wants more bounce and airflow, consider the Saatva Latex Hybrid. If you want a denser, slower-melting foam feel with a deeper hug, consider the Tempur-Pedic TEMPUR-Adapt.
Limitations
This is an all-foam mattress, so it won’t replicate the lift and perimeter stiffness you get from a well-built coil hybrid. If you sit on the edge a lot (tying shoes, working from bed), you’ll feel more compression than you would with reinforced coils. If you’re a strict stomach sleeper, Firm may work, but many people will prefer a flatter hybrid for long-term hip and abdominal comfort.
Alternatives
-
Why choose these models
- You want foam pressure relief with more structured pushback
- You need strong motion isolation for a partner
- You want multiple firmness options within one model
-
Alternatives to consider
- Tempur-Pedic TEMPUR-Adapt: deeper, denser foam feel for people who want more hug
- Nectar Luxe: a softer, more cushioned approach for pressure-focused sleepers
- Saatva Loom & Leaf: premium foam feel with a more traditional luxury finish
Pro tips
- Give it a real break-in window before you lock in a firmness decision.
- Use a breathable mattress protector if you tend to sleep warm.
- Pair it with a supportive foundation so the foam core doesn’t flex unevenly.
- If you’re between Soft and Medium, choose Soft only if shoulder/hip pressure is your top issue.
- For couples, run a quick “edge share” test: both sleepers spend 20 minutes on the outer third to confirm comfort.
- If you wake up with lower-back tightness, try a thinner pillow on back nights and a slightly higher loft on side nights.
- Rotate the mattress head-to-foot a few times per year to even out wear patterns.
- If you sit on the edge daily, add a small bench so you’re not always loading the same perimeter spot.
FAQs
Does the GravityLux feel like traditional memory foam?
It contours like memory foam, but the surface feels more buoyant than classic slow-response styles. In our tests, it was easier to turn on, with less of that stuck-in-place sensation.
Which firmness works best for combination sleeping?
Medium handled back-to-side transitions best in our room. It gave enough shoulder room without letting the hips drift when staying on the back.
How noticeable is motion transfer for couples?
In our partner drills and normal nights, movement stayed localized. Jenna and Ethan both reported fewer wakeups from late turns and get-ups than on bouncier beds.
Will it sleep cool for an all-foam mattress?
It ran cooler than many foams we’ve used, helped by the cover and heat-dispersing design. Very hot sleepers may still prefer latex or coils.
