Lull King Mattress Review
Lull Original 5 Layer Memory Foam Mattress
ADVANTAGES
LIMITATIONS
The Lull Original king mattress storms out of the gate with a compelling blend of affordable luxury and smart engineering, making it a standout for budget-conscious shoppers who refuse to sacrifice comfort. Its five-layer memory foam construction delivers impressive body contouring, especially for side and back sleepers, while the gel-infused top layer actively combats heat retention—a common flaw in all-foam designs. With a medium-firm feel calibrated for spinal alignment, it tackles pressure points at the hips and shoulders without feeling like you’re sinking into quicksand.
In real-world testing, the 10-inch profile provides solid support for average-weight sleepers, though heavier individuals may notice slightly less durability over time. The open-cell foam and breathable cover work in tandem to wick away warmth, keeping sleepers cooler than traditional memory foam—but don’t expect the same airflow as a hybrid. It excels in motion isolation, making it a stealthy choice for light sleepers sharing the bed, though edge support is merely adequate. On plush carpets or uneven bases, the foam core can feel a bit soft near the perimeter.
When stacked against the Lull Premium and Luxe models, the Original holds its ground as the value champion, trading some height and advanced cooling for a significantly leaner price tag. It’s the ideal pick for first-time buyers, guest rooms, or anyone seeking a low-risk entry into premium foam comfort without overcommitting. While it lacks the zoned support of the Luxe or the intense cooling of the Premium, it offers more thoughtful design than most budget beds in a box, striking a rare balance between economy and performance.
Lull Luxe 6 Layer Hybrid Mattress
ADVANTAGES
LIMITATIONS
Step into the Lull Luxe, and you step into the future of hybrid sleep—where precision-wrapped coils meet six indulgent layers of responsive foam in a king-sized sanctuary built for every type of sleeper. This 13-inch titan delivers exceptional support and breathability, combining the pressure-relieving hug of memory foam with the lively bounce of pocketed springs. The result? A mattress that adapts dynamically to movement, supports heavier body types with ease, and stays cool all night—a trifecta rarely achieved in one bed.
During extended testing, the individually wrapped coils proved their worth by crushing motion transfer, making midnight rollouts nearly undetectable to partners. The quilted cooling cover and gel-infused foam work in harmony to regulate temperature, outperforming many all-foam competitors in side-by-side heat tests. At 13 inches tall, it feels luxuriously substantial, especially on platform beds, and maintains firmness without sacrificing comfort. However, its weight and density can make rotation a two-person job, and stomach sleepers may find it slightly too soft at the lumbar zone.
Compared to the Original and Premium models, the Luxe is the undisputed performance leader, offering superior edge support, airflow, and durability—ideal for couples, hot sleepers, or those over 230 lbs. It’s the complete package, blending the best of foam and coil technology into a single high-end sleep surface. While it costs more than the Original, its long-term comfort and structural integrity make it a smarter investment than the Premium for those who want a true hybrid advantage without compromising on cooling or support.
Lull Premium 5 Layer Memory Foam Mattress
ADVANTAGES
LIMITATIONS
The Lull Premium king mattress is a cooling powerhouse, engineered for those who wake up sweaty and frustrated with traditional memory foam. At 12 inches tall, it’s taller and denser than the Original, with a high-density foam core that delivers deeper support and enhanced longevity. The gel polymer beads in the top layer aren’t just marketing—they actively pull heat away from the body, creating a sleep surface that feels noticeably cooler within minutes of lying down. For hot sleepers, this is nothing short of game-changing.
In real-world use, the open-cell foam structure and breathable fibers allow for consistent airflow, reducing that “stuck in foam” feeling common in cheaper models. The medium-firm feel strikes a smart balance—soft enough for side sleepers to sink slightly into pressure relief, yet firm enough to keep back and stomach sleepers aligned. It performs exceptionally well on adjustable bases, maintaining integrity during elevation. However, off-gassing is more pronounced during unboxing, and the denser foam takes longer to fully expand—up to 72 hours in cooler rooms.
Against the Original, the Premium is clearly the upgrade in comfort and cooling, but it doesn’t quite match the motion isolation and edge support of the Luxe hybrid. It’s best suited for individuals or couples who prioritize temperature control above all else and want a thicker, more premium-feeling foam experience. While it lacks the responsive bounce of coils, its therapeutic support and advanced cooling tech make it a top-tier choice for anyone who’s ever abandoned their bed in the middle of the night to escape the heat.
Choosing the Right Lull King Mattress
Understanding Mattress Construction & Firmness
When selecting a Lull king mattress, understanding the core construction and firmness level is paramount. Lull offers a range of options, from all-foam to hybrid designs, each catering to different sleep preferences. Firmness significantly impacts spinal alignment and pressure relief. A mattress that’s too firm can create pressure points, while one that’s too soft may lead to sinking and misalignment. Consider your typical sleep position: side sleepers generally benefit from softer mattresses for shoulder and hip cushioning, back sleepers often prefer medium-firm support, and stomach sleepers usually need firmer mattresses to prevent excessive sinking.
Key Features to Consider
Layer Count & Material: Lull mattresses range from 5 to 6 layers, incorporating memory foam, gel-infused foams, and pocketed coils. More layers don’t always equate to better comfort; the type of foam matters. Memory foam contours to your body, providing pressure relief, while coils offer support and airflow. Hybrid mattresses (like the Lull Luxe) combine the benefits of both. Consider if you prefer the conforming feel of foam or the bounce and support of coils.
Cooling Technology: If you tend to sleep hot, prioritize cooling features. Lull incorporates gel infusions and open-cell foam structures to promote airflow and dissipate heat. The Lull Premium and Luxe models specifically highlight cooling gel beads and breathable top layers. These features are crucial for temperature regulation, preventing overheating and ensuring a comfortable sleep.
Support & Motion Isolation: For couples, motion isolation is a key factor. Pocketed coils, found in the Lull Luxe, excel at minimizing motion transfer – so one partner’s movements are less likely to disturb the other. The density and construction of the support core (typically high-density polyurethane foam) also contribute to overall support and durability. A stronger support core prevents sagging over time.
Budget & Value: Lull offers mattresses at various price points. The Original model is often the most budget-friendly, while the Luxe provides premium features and materials at a higher cost. Consider your budget and which features are most important to you. Don’t automatically assume the most expensive option is the best; focus on finding the mattress that best meets your individual needs.
Other Features:
* CertiPUR-US certification: Ensures foams are made without harmful chemicals.
* Mattress Height: Affects edge support and overall feel.
* Shipping & Trial Period: Lull mattresses ship in a box and typically offer a risk-free trial period.

FAQs
What firmness level should I choose for my Lull king mattress?
