by MemoryLux is the WinkBeds all-foam line, now sold as the GravityLux. It is a 10-inch, all-foam mattress with AirCell memory foam, strong motion isolation, and three firmness options. Its honest weak spot is edge support, which is common to any all-foam build. If you want a premium memory foam mattress with white-glove delivery and a 365-night trial, the Saatva Loom & Leaf is the strongest upgrade in this category.

MemoryLux (WinkBeds GravityLux): what it is
MemoryLux is the WinkBeds all-foam line, which WinkBeds now markets under the name GravityLux. It is a 10-inch, 100% foam mattress made in WinkBeds' Wisconsin factory, using a four-layer build:
- Cover: silky Tencel fabric quilted with roughly 1 inch of gel-infused foam for initial cushioning and airflow.
- Comfort layer: 2 to 3 inches of WinkBeds' patented AirCell memory foam, an open-cell formulation designed to contour without the heat trap of traditional visco foam.
- Transition layer: a polyfoam progression layer that distributes weight and prevents bottoming out.
- Support core: high-density Atlas Core foam that makes this bed firmer and more durable than most boxed foam competitors.
Three firmness options are available: Soft (~4/10), Medium (~6 to 7/10), and Firm (~7.5 to 8/10). Queen pricing typically runs around $1,499 before promotions.

Performance and feel
Pressure relief and contouring
The AirCell comfort layer provides deep, slow-response contouring typical of memory foam. Lab reviews score pressure relief around 9/10, making it one of the stronger performers in the all-foam category. Side sleepers on the Soft or Medium find genuine shoulder and hip relief.
Cooling
The open-cell AirCell foam and Tencel cover help the GravityLux sleep noticeably cooler than traditional visco memory foam. Hot sleepers who have avoided memory foam for temperature reasons generally rate it positively. It does not match the airflow of a coil hybrid, but it outperforms most foam-in-a-box competitors on temperature regulation.
Motion isolation
All-foam construction absorbs movement extremely well. Couples report that the GravityLux is one of the better performers for motion transfer in the premium foam segment, on par with alternatives like the Nectar Premier or Tempur-Pedic Cloud.
Edge support
This is the honest trade-off with any all-foam mattress. The perimeter compresses more than a coil build with a reinforced edge frame. Sleepers who sit or sleep near the edge will notice some give. For a dedicated foam bed, reviewers rate the GravityLux edge support as above average, though it does not match a WinkBed hybrid or the Saatva Classic on this metric.
Support and spinal alignment
The dense Atlas Core provides reliable support for back and stomach sleepers, particularly on the Medium and Firm options. Expert reviews rate spinal alignment at 5/5 for back sleepers on the Medium. The Soft is better suited to lighter-weight side sleepers who want deep pressure relief.
Who the MemoryLux is for
The GravityLux suits sleepers who want the body-contouring, slow-response feel of memory foam and do not sleep or sit regularly at the mattress edge. Couples sensitive to partner movement are a strong fit. Back sleepers on the Medium or Firm, and lighter side sleepers on the Soft, are the core audience. If you sleep hot and have avoided traditional memory foam, the AirCell layer is worth testing on the 120-night trial.
It is less suited to combination sleepers who want bounce and responsiveness, heavier sleepers over 250 lb who need firmer edge support throughout the night, or anyone who prefers the lifted feel of a coil hybrid.
Saatva Loom & Leaf: the closest premium alternative
If you want a premium all-foam memory mattress with a significantly longer trial and white-glove delivery, the Saatva Loom & Leaf is the direct comparison. Both are high-density, American-made memory foam mattresses. The key differences:
- Trial: 365 nights with the Loom & Leaf vs. 120 nights for MemoryLux.
- Delivery: Saatva includes free white-glove delivery, full setup, and old-mattress removal. MemoryLux ships standard.
- Warranty: Lifetime on both.
- Price: Loom & Leaf queens start around $1,695, a modest step up from MemoryLux at approximately $1,499.
- Firmness options: MemoryLux offers Soft, Medium, and Firm. Loom & Leaf offers Relaxed Firm (~6/10) and Firm (~8/10).
If you specifically need a Soft option, MemoryLux has an advantage. If you want the most flexible trial and service package for a memory foam mattress, the Loom & Leaf wins on terms.
Saatva Classic: the coil-hybrid option
For sleepers considering an upgrade from foam to a coil-hybrid feel, the Saatva Classic offers a different profile. Its dual-coil construction with individually wrapped coils delivers firmer, more stable edges than any all-foam mattress. The 365-night trial and lifetime warranty match the Loom & Leaf, and white-glove delivery is included. Queen pricing runs around $1,395 on promotion. It is not a like-for-like alternative to MemoryLux on feel, but it is worth cross-shopping if you want stronger edge support and an on-top innerspring feel.
MemoryLux (WinkBeds GravityLux) is a well-built, cooler-than-average all-foam mattress with strong motion isolation and pressure relief. Its main limitation is edge support, as with any foam-only build. For memory foam buyers who want the longest trial and premium service, the Saatva Loom & Leaf is the strongest upgrade at a similar price point.
Frequently asked questions
Is MemoryLux the same as WinkBeds GravityLux?
Yes. WinkBeds originally marketed its all-foam model as the MemoryLux. The brand now sells this mattress under the name GravityLux. The construction, specs, and warranty are the same product line.
Is the WinkBeds GravityLux good for back pain?
The Medium and Firm options provide solid spinal alignment for back sleepers, and the AirCell foam contours well around pressure points. Back pain sleepers who prefer a slow-response foam feel will find it a strong candidate. Those who need firm edge support or a zoned lumbar system may prefer a hybrid like the Saatva Classic.
How does MemoryLux compare to Tempur-Pedic?
Both are premium all-foam memory mattresses. The GravityLux uses an open-cell AirCell foam that tends to sleep cooler than Tempur-Pedic's proprietary TEMPUR material. WinkBeds also offers a 120-night trial vs. Tempur-Pedic's 90 nights, and a lifetime warranty vs. 10 years. Tempur-Pedic carries more brand recognition and wider retail availability.
Does MemoryLux have fiberglass?
WinkBeds does not disclose fiberglass in the GravityLux construction and uses a Tencel fabric cover rather than a glass-fiber fire barrier. If this is a concern, confirm directly with WinkBeds before purchasing.
What is the MemoryLux return policy?
WinkBeds offers a 120-night trial with a mandatory 30-night break-in period before a return is eligible. Firmness exchanges carry a $49 fee. The mattress comes with a lifetime warranty.
