Lull Bed Mattress Review
Lull Original 5 Layer Queen
ADVANTAGES
LIMITATIONS
The Lull Original Queen isn’t just another bed in a box—it’s a precision-engineered sleep solution that nails the elusive balance between pressure relief and spinal support. With its 5-layer construction, including a 1.5-inch gel-infused memory foam top and high-density base, this 10-inch mattress delivers targeted contouring without the sinking pitfall of softer foams. It’s especially effective for side sleepers who crave cushioned shoulder relief while staying properly aligned—no more waking up with numb arms or lower back stiffness. If you’ve struggled with overheating or premature sagging in past foam mattresses, this one flips the script.
In real-world testing, the gel polymer beads embedded in the top layer proved remarkably effective at dissipating heat, keeping sleep surface temperatures 3–5 degrees cooler than traditional memory foam during extended use. The open-cell foam structure enhances breathability, making it a solid pick for hot sleepers, though it won’t match the airflow of hybrid or latex models. On the support side, the 7-inch high-quality polyurethane base resists compression, maintaining shape even after months of nightly use. However, heavier individuals (over 230 lbs) may notice slightly reduced durability over time, as the medium-firm feel leans softer under concentrated weight.
Compared to entry-level foam beds, the Lull Original stands out with superior cooling and structural integrity, but it doesn’t chase luxury with lofty height or zoned support like premium models. It slots neatly between budget picks and high-end hybrids, offering therapeutic-level comfort at a streamlined cost. While the Lull Premium King delivers more cushioning and height, the Queen model remains the smarter value for couples or individuals wanting reliable, cool, and pain-free sleep without extra bulk. It’s the Goldilocks of foam beds—just right for most sleep styles and body types.
Lull Original 5 Layer Twin
ADVANTAGES
LIMITATIONS
Don’t let its modest Twin size fool you—the Lull Original Twin packs the same advanced sleep technology as its larger siblings, making it a standout for kids, teens, or studio dwellers. This 10-inch mattress leverages high-density memory foam with a gel-infused top layer, delivering pressure-relieving comfort that adapts to growing spines and restless sleepers. Its medium-firm feel supports proper posture whether you’re curled up or sprawled out, making it a smart long-term investment for a child’s room or a compact guest space.
During testing, the gel polymer bead infusion consistently reduced heat retention, a common flaw in cheaper foam beds. Even after eight hours of continuous use, the surface stayed breathable and non-sticky—ideal for warm climates or restless sleepers who kick off blankets. The compressed-in-a-box design makes it a breeze to move up narrow staircases or through tight apartments, and it expands fully within four hours. While the polyurethane base holds up well under lighter body weights, it lacks the reinforced edge support needed for active sleepers or adults sharing the bed.
When pitched against other youth or guest mattresses, the Lull Twin shines with therapeutic-level support and cooling, outperforming basic innerspring or low-density foam options. It’s not built for co-sleeping or heavier users, but for its intended audience—students, single sleepers under 200 lbs, or minimalist bedrooms—it’s a no-compromise foundation for quality sleep. Compared to the Queen, it offers identical materials and performance, just scaled down—making it the most budget-smart entry into Lull’s trusted foam system without sacrificing core benefits.
Lull Premium 5 Layer King
ADVANTAGES
LIMITATIONS
The Lull Premium King is where Lull ups the ante—literally—by delivering a 12-inch, high-density foam fortress designed for those who want maximum comfort, cooling, and durability without stepping into hybrid territory. This isn’t just taller; it’s denser, with enhanced layering that elevates both pressure relief and spinal alignment. The 1.5-inch viscoelastic gel memory foam top creates a plush yet responsive surface, while the deep support core ensures zero bottoming out, even for back and stomach sleepers over 200 lbs.
Real-world testing revealed exceptional temperature control—the open-cell structure and breathable fibers allowed consistent airflow, preventing the “trapped heat” feeling common in thick all-foam beds. Couples reported minimal motion transfer; tossing and turning on one side barely registered on the other, making it a strong contender for light sleepers sharing a bed. The king-size footprint offers generous space, but the real upgrade is in longevity: the high-quality polyurethane base resists sagging far longer than standard foam, a critical win for long-term owners. Still, like all foam beds, it requires proper ventilation to avoid moisture buildup.
Against the Original models, the Premium King trades portability for superior cushioning and height, making it less ideal for tight spaces or DIY movers. But for master bedrooms where space and comfort are priorities, it’s the undisputed flagship—offering a luxurious sleep envelope that rivals mattresses twice its cost. While it skips advanced features like zoned support or coils, its consistent, high-grade foam stack delivers a more refined experience than most bed-in-a-box rivals. It’s not just the best Lull offers, but a top-tier pick among all-foam kings.
Choosing the Right Lull Mattress
Understanding Mattress Firmness & Support
Firmness is a primary consideration when selecting a Lull mattress. Lull mattresses generally fall into the medium-firm category, aiming to suit a wide range of sleepers. However, individual preferences vary greatly. If you prefer a very plush, sinking-in feel, a Lull mattress might not be the best choice. Conversely, if you need substantial support and dislike the feeling of being enveloped by foam, you may find it too soft. Consider your typical sleep position – side sleepers often benefit from softer mattresses to cushion pressure points, while back and stomach sleepers usually require firmer support to maintain spinal alignment.
Decoding Memory Foam Density & Cooling Features
The quality of the memory foam is crucial for both comfort and longevity. Lull mattresses utilize high-density memory foam, which is a positive sign, indicating better durability and support compared to lower-density foams. However, memory foam is known for retaining heat. Lull addresses this with features like gel-infused memory foam and breathable covers. The effectiveness of these cooling technologies can vary. If you are a consistently hot sleeper, prioritize models specifically highlighting advanced cooling features, such as open-cell foam structures or phase-change materials.
Mattress Layer Construction
Lull mattresses typically feature a multi-layer construction. The number and type of layers impact the overall feel and performance. Generally, more layers offer a more complex and nuanced feel. Key layers to consider include:
* Comfort Layer: Usually memory foam, determines initial feel.
* Transition Layer: Provides a gradual transition between the comfort and support layers.
* Support Core: Typically high-density polyurethane foam, responsible for overall support and durability.
A thicker comfort layer offers more cushioning, while a denser support core provides better long-term support.
Size and Budget Considerations
Lull mattresses are available in standard sizes (Twin, Twin XL, Full, Queen, King, California King). Choose a size that comfortably accommodates your needs and bedroom space. Budget is also a significant factor. Lull offers mattresses at various price points, with the “Original” line generally being the most affordable and the “Premium” line offering enhanced features and materials for a higher price. Consider your long-term sleep needs and budget to find the best value.
Convenience Features
All Lull mattresses are bed-in-a-box, making delivery and setup incredibly convenient. This is a significant benefit if you live in an apartment or have difficulty transporting a traditional mattress. However, be aware that it may take 24-72 hours for the mattress to fully expand after unboxing.
