The Lull Original Mattress is a 10-inch, medium-firm all-foam mattress built to balance light memory-foam contouring with steadier support. In our hands-on testing, it felt calm and controlled for movement, gave us reliable lumbar support for back sleeping, and stayed more medium-firm than sinky. The trade-off was warmth over longer stretches and a firmer feel than we wanted for pressure-sensitive side sleeping.

|---|---|---|---|
| Lull Original Mattress | 3.9/5.0 | Reliable support, strong motion control, frequent promotions | Average edges, can run warm, firmer feel for some side sleepers |
Final Verdict
The Lull Original Mattress is a straightforward, medium-firm foam mattress that puts stable support and low motion transfer ahead of deep sink. I’d buy it for back-sleep comfort and the quiet surface, but I’d pass if you need cooler sleep or deeper pressure relief at the shoulders.
Who It’s For
-
Back sleepers who want a steadier, less “huggy” foam feel
-
Couples who care more about motion isolation than bounce
-
Value shoppers who tend to buy during promotions
Who It’s Not For
-
Hot sleepers who overheat easily
-
Curvy or pressure-sensitive side sleepers who need a plusher top
-
People who sit on the edge a lot and want stronger perimeter support
How We Tested It
We slept on the mattress over multiple weeks and rotated mainly between back and side positions. Our testing included repeat checks for Support, Cooling, Pressure Relief, Motion Isolation, Responsiveness, Edge Support, and Durability. We also ran partner-movement checks, timed how quickly the surface settled after turns, watched for pressure buildup during longer side-lying sessions, and repeated sit tests at the edge to see how the perimeter held up over time.
Our Testing Experience
Our first impression was that the surface felt clean and medium-firm. It didn’t have the slow, deep sink of a softer foam bed, which helped keep my lower back level instead of letting it dip. Marcus noticed the warmth after about an hour. He liked the hip support, but the edge gave more than he wanted when he sat down to put on socks. Carlos kept coming back to the same point: on his back, the mattress held him in a flatter, more even position through the mid-back. Mia was comfortable at first on her side, but after longer stretches she started shifting to take pressure off her shoulder.
What we liked
-
Steady lumbar support for back sleeping without a deep sink

Predictable, medium-firm feel that stayed consistent from week to week
Who it is best for
-
Back sleepers and combo sleepers who prefer support-first foam
-
Couples prioritizing motion isolation
-
Guest rooms where a safe, middle-of-the-road firmness makes sense
Where it falls short
-
Heat buildup over longer sessions, especially for hot sleepers
-
Side-sleep pressure relief at the shoulders and outer hips
-
Edge support when sitting or sleeping near the perimeter
Pros & Cons
| Pros | Cons |
|---|---|
| Balanced medium-firm support for back sleeping | Can sleep warm for hot sleepers |
| Strong motion isolation for a foam bed | Edge support is only average |

| Support | 4.2 | Kept my hips from dipping on my back and held the midsection steady |
| Cooling | 3.7 | Comfortable early on, but warmer over longer stretches |

Choosing Guide
Pick the Lull Original Mattress if you want a medium-firm foam feel that stays supportive on your back and keeps movement controlled across the surface. The trade-off is that you’re not getting the airflow and perimeter structure of a hybrid, and side sleepers who need deeper shoulder relief may want a softer top layer.
If you want a plusher, thicker all-foam feel for pressure relief, consider the Nectar Classic Memory Foam Mattress. If you want more bounce and stronger edges for combo sleeping and easier repositioning, consider the DreamCloud Classic Hybrid Mattress.
Limitations
The biggest trade-offs here are heat management, edge strength, and side-sleep pressure relief. The medium-firm surface feels supportive first, which works well for back sleeping but is less forgiving at the shoulder during long side-sleep sessions. If you sit on the edge often, share a smaller size, or usually sleep hot, those compromises will stand out quickly.
Vs. Alternatives
Why choose this type of mattress
-
You want a steady, medium-firm foam feel without too much sink
-
You prioritize motion isolation for shared sleep
-
You’re shopping around major promotions
Alternatives to consider
-
Casper The One: responsive all-foam feel with a similarly simple profile
-
Nectar Classic: thicker foam build aimed more at contouring pressure relief
-
DreamCloud Classic Hybrid: hybrid option for more bounce and airflow
Pro Tips
-
Give it 48 hours to fully expand and settle before judging the feel.
-
Use breathable sheets and a lighter comforter if you run warm.
-
For side sleeping, use a slightly higher-loft pillow to help keep your neck neutral.
-
If the edge feels soft, the corners usually feel a bit steadier than the middle.
-
Rotate the mattress periodically to even out wear.
-
Use a supportive, flat foundation so the foam core stays even.
-
If you feel shoulder pressure, try a thin topper before replacing the whole setup.
-
Keep the room a little cooler when possible if heat buildup bothers you.
-
When testing motion control, pay more attention to whether movement wakes you up than whether you feel any movement at all.
FAQs
Does the Lull Original Mattress feel more like “hug” or “support”?
It leans support-first. I felt contouring at the hips and shoulders, but the surface stayed flatter and less sinky than many softer memory-foam beds.
Is it good for couples?
Yes, especially for motion isolation. In our testing, movement stayed fairly contained, though the perimeter compressed if both sleepers drifted toward the edge.
Does it sleep hot?
It can. The cooling features help early on, but in our testing the mattress held more warmth after an hour or two than better-ventilated options.
Is it easy to move around on?
Reasonably. I didn’t feel stuck, but quick turns still came with some foam drag compared with a hybrid.
