The four mattresses in Luna's pocket-spring hybrid range share cooling gel foam and reinforced edges, but they feel noticeably different in use. The Memory 1000 is the easiestgoing and least expensive, the 2500 adds firmer midsection support, the 4000 Plush gives side sleepers the most cushioning, and the 4000 Support is the strongest choice for back sleepers and couples.

Which Luna model stood out?
Luna Memory 1000: This is the sensible lower-cost pick for a guest room or an average-weight sleeper who wants a familiar medium feel. It is comfortable across several positions, but the thinner build gives heavier hips less support.
Luna Memory 2500: The 2500 is the best all-around choice. It holds the midsection more securely than the 1000 without feeling as unyielding at the shoulders as the 4000 Support.
Luna 4000 Plush: Choose the Plush for side-sleeping comfort. It relieved shoulder and hip pressure sooner than the other models and kept partner movement quiet, though stomach sleepers may find it too soft.
Luna 4000 Support: This is the strongest option for back sleepers, heavier couples, and anyone bothered by roll-together. It kept the hips most level and the edge most stable, but pressure-sensitive side sleepers should choose the Plush.

How we compared the four models
We used the same test routine on all four models with sleepers weighing 145 to 230 pounds. Along with back, side, and brief stomach-sleeping sessions, we recorded center sink with a 44-pound weight and compared a 150-pound load at the center and 2 inches from the edge. A 10-pound ball dropped from 6 inches, with a sensor 18 inches away, showed how quickly movement faded. We also tracked surface temperature after 30 minutes, used pressure maps to compare shoulder and hip pressure, and timed slow rollovers for ease of movement. Sitting and lying near the perimeter rounded out our edge checks, while repeated nights showed whether support stayed consistent.
Luna Mattress: our testing experience
Luna Memory 1000
Our testing experience
The 1000 felt like a true medium, about 5.5 out of 10, and required almost no adjustment time. A 44-pound weight sank 1.7 inches at the center. With 150 pounds applied, the center compressed 2.9 inches and the area 2 inches from the edge reached 3.3 inches, so sitting felt secure even though heavier hips settled farther than they did on the other Luna models. In the ball-drop test, noticeable vibration faded after 1.3 seconds. That was quiet enough for most couples, but not as controlled as either 4000.
What we liked
- A familiar medium feel that works across back, side, and combination sleeping
- A foam-reinforced edge that stays stable enough for sitting
- The lowest starting price in the Luna range
Who it is best for
- Average-weight combination sleepers
- Guest rooms that need a broadly comfortable feel
- People who want gentle contouring without a deep foam hug
Where it falls short
- Heavier stomach sleepers who need their hips held higher
- People who want an immediate, springy response
- Anyone who prefers the more substantial feel of a 25 cm mattress
Pros & cons
| Pros | Cons |
|---|---|
| Versatile medium feel | More sink under heavier hips |
| Secure edge for sitting | Surface is not especially quick or springy |
| Breathable gel foam and knit cover | Least midsection support in the range |

Luna Memory 2500
Our testing experience
The 2500 felt distinctly firmer than the 1000 at 6.5 out of 10, and the improvement was clearest beneath the hips. The 44-pound weight sank 1.4 inches, while the 150-pound load compressed the center 2.4 inches and the edge 2.7 inches. Movement from the ball drop settled in 1.1 seconds, and the foam recovered 90% of its height in 2.2 seconds after the load was removed. The surface still contours slowly, but it never made position changes feel laborious.
What we liked
- Noticeably stronger hip and lower-back support than the 1000
- Reliable edge-to-edge support for sitting and sleeping
- A stable surface that still allows easy position changes
Who it is best for
- Back sleepers who prefer a medium-firm mattress
- Couples who want support without the hardest feel in the range
- Combination sleepers who turn often
Where it falls short
- Lighter side sleepers with sensitive shoulders
- People who want the deeper cushioning of the 4000 Plush
- Anyone who dislikes the slower contour of memory foam
Pros & cons
| Pros | Cons |
|---|---|
| More support than the 1000 | May feel firm to lighter side sleepers |
| Steady when a partner moves | Foam response is not immediate |
| Reinforced edge adds usable space | Less cushioning than the 4000 Plush |

Luna 4000 Plush
Our testing experience
The 4000 Plush landed at 4.5 out of 10, making it the only genuinely soft-feeling option here. A 44-pound weight sank 2.0 inches, and side-sleeping pressure maps showed 12% less peak shoulder pressure than on the 2500. Movement faded after 0.9 seconds in the ball-drop test, the second-best result in the group. After 30 minutes, the surface warmed by 5.4°F—reasonable for a softer foam hybrid, though not cool enough to call temperature-neutral for every hot sleeper. Heavier stomach sleepers still felt their hips drop too far.
What we liked
- The strongest pressure relief at the shoulders and hips
- Strong motion control for a shared bed
- A soft-to-medium surface made for side sleeping
Who it is best for
- Side sleepers who need more shoulder and hip cushioning
- Couples who wake easily when a partner moves
- Lighter sleepers who find medium-firm mattresses unyielding
Where it falls short
- Stomach sleepers who need a flat, supportive surface
- Heavier sleepers whose hips sink deeply into soft foam
- People who prefer fast pushback when they turn
Pros & cons
| Pros | Cons |
|---|---|
| Soft feel cushions pressure points | Too soft for some stomach sleepers |
| Strong motion control for couples | Slower response than firmer Luna models |
| Reinforced edge supports edge sleep | Less hip support under heavier bodies |

Luna 4000 Support
Our testing experience
The 4000 Support felt firmest at 6.8 out of 10 and kept our hips higher than every other model. The 44-pound weight sank 1.3 inches; under 150 pounds, the center compressed 2.1 inches and the edge 2.4 inches. Ball-drop vibration disappeared after 0.8 seconds, the quickest result in the lineup, and the foam recovered 90% of its height in 1.6 seconds. Back sleepers appreciated that steady pushback. Side sleepers with sensitive shoulders did not get the same relief they found on the Plush.
What we liked
- The most secure lumbar and hip support in the range
- The best motion control and least roll-together
- The strongest edge for sitting or sleeping near the side
Who it is best for
- Back sleepers who want a firmer, level surface
- Heavier couples who need steady midsection support
- Light sleepers who notice a partner turning over
Where it falls short
- People who want a plush, body-hugging surface
- Side sleepers who need deep shoulder cushioning
- Lightweight sleepers who prefer more give
Pros & cons
| Pros | Cons |
|---|---|
| Strongest support in the range | May feel too firm for people who prefer plush beds |
| Best shared-bed stability | Less shoulder cushioning than the Plush |
| Firm, dependable edge | Firmer surface may aggravate pressure points |

How the Luna mattresses scored
| Mattress | Overall Score | Support | Pressure Relief | Cooling | Motion Isolation | Durability | Responsiveness |
|---|---|---|---|---|---|---|---|
| Luna Memory 1000 | 3.9 | 4.0 | 3.9 | 4.0 | 4.1 | 3.8 | 3.8 |
| Luna Memory 2500 | 4.2 | 4.4 | 4.1 | 4.2 | 4.2 | 4.2 | 4.0 |
| Luna 4000 Plush | 4.2 | 4.1 | 4.5 | 4.2 | 4.3 | 4.2 | 3.9 |
| Luna 4000 Support | 4.4 | 4.6 | 4.2 | 4.3 | 4.4 | 4.4 | 4.1 |
The 4000 Support leads at 4.4 out of 5 because it combines the range's strongest support, edge stability, and motion control. The 4000 Plush earns its 4.2 by doing one job especially well: relieving side-sleeping pressure. Also rated 4.2, the 2500 is the safer all-around choice for shoppers who want firmer support without the Support model's harder shoulder feel. The 1000 finishes at 3.9; it is comfortable and good value, but its thinner build reaches its limits sooner under heavier weight.
Which Luna mattress should you choose?
Start with firmness, body weight, and sleep position. Pick the 4000 Support if you sleep on your back, share the bed, or need the strongest hold beneath your hips. Choose the 2500 for a slightly more forgiving version of that support. The 4000 Plush is the clear choice for side sleepers with shoulder or hip pressure, while the 1000 makes the most sense for a guest room or an average-weight sleeper who wants a medium feel at the lowest price. Hot sleepers should know that all four use open-cell gel foam, but none felt as airy as a fiber-heavy hybrid.
Where each Luna mattress falls short
The 1000 is the least supportive choice for heavier back and stomach sleepers. The 2500 fixes much of that problem, but its memory foam still takes a moment to respond. The 4000 Plush trades hip support for pressure relief and can let a stomach sleeper's midsection dip. The 4000 Support makes the opposite compromise: it holds the hips firmly but gives lighter side sleepers less room at the shoulder. Our test period can show early consistency, not how any model will feel after years of use.
How Luna compares with similar hybrids
Silentnight Just Breathe Eco Comfort Hybrid: Choose this model over Luna if airflow and easy movement matter more than a slow foam contour. Its 1,000 zoned pocket springs and recycled-fiber comfort layer feel more buoyant than the Luna hybrids, with less of a memory-foam hug. It starts near the 4000 models' price, but retailer listings vary between medium-firm and firm, so check the exact version before ordering. Read our Silentnight mattress review for the broader brand comparison.
Mlily Bamboo+ Memory 800 Pocket Mattress: This is the better value pick if you want a medium hybrid with a removable cover. It uses 800 pocket springs, 2 cm of bamboo-charcoal memory foam, and a reinforced border, so it feels simpler and less substantial than the 2500 or either 4000. Choose Mlily for the lower starting price and easier cover care; choose Luna for more firmness options, higher spring counts, and a 10-year guarantee. Our Mlily mattress review covers the brand in more detail.
How to get the best from a Luna mattress
- Give the mattress at least the required 30 nights before using the retailer's comfort exchange.
- Rotate it on schedule, especially if you sit on the same edge every day.
- On the 2500 and 4000 Support, check your pillow height before adding a topper; an overly tall pillow can create neck pressure on a firmer surface.
- For couples, use a stable foundation and tighten the frame before judging partner movement.
- If pressure builds at your shoulder or hip, move toward the Plush. If your lower back dips, move toward the 2500 or 4000 Support.
FAQs
Which Luna Mattress model is best for back sleepers?
The 4000 Support is the best match for back sleepers who want the firmest, most level surface. Choose the 2500 if you want similar midsection support with slightly more give.
Which model is best for side sleepers with pressure points?
The 4000 Plush gives the shoulder and hip the most room to settle. It is the clear choice for lighter or pressure-sensitive side sleepers.
Which model is most couple-friendly?
The 4000 Support controlled roll-together best and had the strongest edge. Couples who prefer a softer surface should choose the 4000 Plush, which also kept movement well contained.
