Liberty Mattress keeps its lineup simple and relatively affordable. Lulu has the familiar bounce of a traditional innerspring, Black Frost adds a cooler and more cushioned hybrid feel, and Serene is the firmest and steadiest of the three. The differences were clear enough in our rotation that choosing one comes down to whether you value easy movement, pressure relief, or stable support most.

What’s in the Liberty Mattress lineup?
| Mattress | Overall Score | Pros | Cons | Ideal For |
|---|---|---|---|---|
| Lulu | 3.7 | Responsive spring feel; low listed price; easy position changes | Transfers more movement; limited cushioning at the shoulders and hips | Budget shoppers; guest rooms; sleepers who like a traditional bed |
| Black Frost | 3.8 | Cooler surface; stronger pressure relief; comfortable in several positions | Softer perimeter; slower rebound than Lulu | Hot sleepers; side sleepers; combination sleepers who want more cushioning |
| Serene | 4.0 | Firm support; strong motion isolation; stable edges | Not enough shoulder cushioning for many lightweight side sleepers | Back and stomach sleepers; couples; people who prefer a firm surface |
Which Liberty model stood out?
Each model had a distinct strength. Lulu was the easiest to move on and the least expensive, but it also transferred the most partner movement. Black Frost provided the best balance of cooling and side-sleep pressure relief. Serene felt the most secure under the hips, at the edge, and during partner-movement checks. Marcus Reed preferred Black Frost on warm nights, Mia Chen favored its extra shoulder and hip cushioning, and Ethan Cole chose Serene for its firmer, more controlled feel.

What did our test cover?
Following our mattress-testing process, we rotated regular sleep, naps, and reading sessions across all three mattresses for several weeks. The same 5-point scale covered support, cooling, pressure relief, motion isolation, responsiveness, edge support, and early durability. We checked back and side-sleep alignment, tracked surface warmth over 30–45 minutes, noted shoulder and hip pressure, repeated a partner getting in and out of bed, and sat and stood near the perimeter. Weekly notes helped separate first impressions from changes that persisted after break-in.
Liberty Mattress: Our Testing Experience
Lulu
Our Testing Experience
Lulu felt familiar from the first night: buoyant, lightly cushioned, and easy to turn on. During back sleep, the coils kept our hips from dropping too far, and the surface stayed level through longer reading sessions. That quick response earned a 4.0/5, the highest in this group. The same bounce carried movement across the bed, however, which pulled motion isolation down to 3.2/5. Side sleepers also felt more concentrated pressure at the shoulder than they did on Black Frost. In the 30–45-minute warmth check, Lulu stayed reasonably neutral but never felt actively cool.
What we liked
-
The responsive spring feel makes turning and getting out of bed easy.
-
Back sleepers get steady hip support without a deep cradle.
-
The low listed price makes sense for a guest room or a basic primary bed.
Who it is best for
-
Budget shoppers who still want a traditional innerspring feel
-
Combination sleepers who change positions often
-
Guest rooms where broad comfort and a low price matter most
Where it falls short
-
Partner movement is more noticeable than on Black Frost or Serene.
-
The comfort layers do not provide enough shoulder or hip cushioning for many dedicated side sleepers.

Black Frost
Our Testing Experience
Black Frost offered the most immediate cushioning and the coolest surface. In the 30–45-minute warmth check, it built heat more slowly than Lulu or Serene, which matched its 4.2/5 cooling score. Mia’s shoulder settled farther into the gel-foam top during side sleep, reducing the concentrated pressure she felt on Lulu and Serene; pressure relief scored 4.0/5. It was still easy to change positions, but the foam took a little longer to recover than Lulu’s springier surface, reflected in a 3.6/5 responsiveness score. The perimeter also compressed more than Serene’s when we sat and stood near the edge.
What we liked
-
The gel-foam surface stayed coolest during our timed warmth checks.
-
Its deeper cushioning relieved shoulder and hip pressure better than the other two models.
-
The medium-plush feel worked well for side sleep and occasional back sleep.
Who it is best for
-
Hot sleepers who want a cooler first-contact feel
-
Side sleepers who need more room for the shoulder and hip to sink
-
Combination sleepers who prefer cushioning without a deep memory-foam hug
Where it falls short
-
The edge feels less secure than Serene’s when sitting or sleeping near the perimeter.
-
Its foam comfort layers respond more slowly than Lulu’s springier surface.

Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 3.7 | Supportive coils beneath a more yielding comfort layer |
| Cooling | 4.2 | Lowest heat buildup of the three during timed checks |
| Pressure Relief | 4.0 | Best shoulder and hip cushioning in this group |

| Edge Support | 3.6 | Perimeter compresses more than Serene’s |
| Durability | 3.7 | Minor surface settling, with no structural change during the test |
| Overall | 3.8 | Best for cooling and pressure relief, with a softer edge |
Serene
Our Testing Experience
Serene felt firm immediately and changed the least as the test progressed. Its pocketed coils held the pelvis level during back and stomach sleep, earning 4.4/5 for support. When one person rolled over or got out of bed, the other side remained noticeably calmer than it did on Lulu; motion isolation scored 4.3/5. The edge also compressed less during repeated sit-and-stand checks, supporting a 4.2/5 score. Despite the firm surface, turns were easy because the mattress did not allow much sink. The drawback was equally clear: Mia felt shoulder pressure build during longer side-sleep sessions, especially compared with Black Frost.
What we liked
-
The firm surface kept the hips level during back and stomach sleep.
-
Pocketed coils limited partner disturbance better than the other two models.
-
The perimeter felt secure when sitting, standing, or lying near the edge.
Who it is best for
-
Back and stomach sleepers who want firm support
-
Couples and light sleepers who are easily disturbed by movement
-
People who prioritize a stable surface over deep cushioning
Where it falls short
-
Lightweight side sleepers are likely to feel pressure at the shoulder.
-
It provides less immediate cushioning than Black Frost for sensitive joints.

How did each mattress score?
| Mattress | Overall Score | Support | Pressure Relief | Cooling | Motion Isolation | Durability | Responsiveness |
|---|---|---|---|---|---|---|---|
| Lulu | 3.7 | 3.8 | 3.6 | 3.5 | 3.2 | 3.8 | 4.0 |
| Black Frost | 3.8 | 3.7 | 4.0 | 4.2 | 3.5 | 3.7 | 3.6 |
| Serene | 4.0 | 4.4 | 3.7 | 3.6 | 4.3 | 4.1 | 4.0 |
Serene earned the highest overall score because it combined strong support, motion isolation, responsiveness, and edge stability. Black Frost is the better choice when cooling and pressure relief outweigh perimeter firmness. Lulu’s lower score mainly reflects motion transfer and modest side-sleep cushioning, not a lack of basic support.
Which Liberty Mattress should you choose?
Choose Black Frost if you sleep mainly on your side, tend to overheat, or want a more cushioned surface. Choose Serene if you sleep on your back or stomach, share the bed with a light sleeper, or prefer a firm and stable edge. Lulu is the practical choice for a tighter budget, a guest room, or anyone who likes the quick response of a traditional innerspring. Body weight still matters: lighter side sleepers generally need more surface give, while heavier back and stomach sleepers usually benefit from stronger resistance under the hips.
What should you know before buying?
Product information is uneven across this lineup. The retailer does not list the height of Lulu or Serene, and detailed layer specifications are limited for both. Prices and availability can also change by size or store, so confirm the current listing before ordering online. Lulu transfers too much movement for many light-sleeping couples. Black Frost has the softest perimeter and will not satisfy someone who wants a distinctly firm bed. Serene creates the most shoulder pressure and is the weakest match for lightweight side sleepers.
How does Liberty compare with other mattresses?
Liberty’s advantage is a straightforward range of feels without a long list of options. Lulu covers the low-price traditional category, Black Frost adds a more cushioned cooling hybrid, and Serene supplies firmer pocket-coil support. The tradeoff is limited public detail about policies and construction on Lulu and Serene.
Saatva Classic is a premium step-up, not a same-price substitute. It costs substantially more but adds three firmness choices, two heights, a Euro pillow top, lumbar-focused construction, in-room setup, a 365-night trial, and a lifetime warranty. It is the stronger choice for shoppers who want extensive service and customization and are comfortable spending well above Liberty’s range.
Brooklyn Bedding Signature Hybrid overlaps the upper end of Liberty’s prices when promotions are available. It offers soft, medium, and firm choices, an optional pillow top, a clearly documented coil-and-foam build, a 120-night trial, and a limited lifetime warranty. Choose it over Black Frost or Serene if selecting firmness matters more than buying from a local retailer.
Nectar Classic Memory Foam is the closest alternative to Serene Queen by current price, but the feel is very different. Nectar uses an all-foam, medium-firm design with deeper contouring, a 365-night trial, and a Forever Warranty. It suits shoppers who want pressure relief and minimal coil bounce; Serene remains better for a firmer surface, easier movement, and stronger edge stability.
What should you do before buying?
-
Use the bed for about two weeks before deciding, in line with a practical mattress trial whether the feel works for you. The surface and your body both need time to adjust.
-
Pair Black Frost with breathable sheets and a protector that does not trap heat; heavy bedding can mask the cooler surface.
-
If Serene creates shoulder pressure, try a thin topper rather than a deep one so you do not erase its support advantage.
-
Rotate Lulu regularly to spread wear across its spring surface.
-
Couples should copy their normal routine in the store: lie down together, roll over, and have one person get out of bed while the other stays still.
-
Use a stable, compatible foundation. A flexible or uneven base can change support and motion more than expected.
-
Compare the same size across brands, including delivery and foundation costs, rather than relying on the lowest advertised starting price.
FAQs
Which Liberty Mattress model is best for hot sleepers?
Black Frost is the best option of the three. Its gel-infused memory-foam layer felt coolest at first contact and accumulated the least heat during our 30–45-minute checks.
Which model is best if I sleep on my stomach?
Serene is the strongest starting point. Its firm pocketed-coil system kept the hips more level during stomach and back sleep than Lulu or Black Frost.
I’m a side sleeper with sensitive shoulders. What should I pick?
Choose Black Frost. Its medium-plush foam top allowed more shoulder and hip sink and produced the best side-sleep pressure relief in this group.
Which one is most partner-friendly for light sleepers?
Serene isolated movement best. Its pocketed coils kept the opposite side calmer when one person rolled over or got out of bed.
Which model is the best simple guest-room choice?
Lulu is the most practical guest-room option. It has a familiar, balanced innerspring feel, changes positions easily, and carries the lowest listed price of the three.
