We track the Queen Lull Original Premium all-foam mattress alone.
Pick one or more traits above and we will show the strengths and watch-outs that matter for this mattress.
Choose the Lull Original Premium Mattress if you want a support-forward all-foam mattress for back or combination sleeping and you like quicker response than classic slow memory foam. Compare alternatives first if you need softer side-sleeper cushioning, very low motion transfer, or more certainty about its usual sale price.
Pressure-relief testing scored 8/10. Sinkage measured 1.65–1.71 inches, a very minimal depth, while the comfort material measured around 5 inches. The mattress offers more foam depth than the Original but still feels support-forward rather than deeply plush.
Sinkage measured 1.65–1.71 inches. Together with the 12-inch foam construction and 7-inch high-density support core, that shallow contour creates a stable, support-forward surface.
Motion-transfer testing scored 7.1/10 with peak-to-peak acceleration around 12.35–12.85 m/s². That result indicates noticeable partner movement, so easily disturbed couples should compare mattresses with lower measured transfer.
A fixed 12 lb load creates the impact while an accelerometer records the movement that crosses the mattress.
Cooling testing scored about 7.8/10 and sinkage measured 1.65–1.71″. The gel-infused open-cell foam and shallow body contact help limit heat buildup, but the solid foam core cannot circulate air as freely as a coil support system.
Edge-support testing scored 8.8/10, sitting compression measured 3.92–4.08 inches, and lying edge support rated Excellent. The perimeter is stable for sleeping near it and reasonably supportive for sitting.
We measure seated compression, then check how secure the surface remains while lying directly along the edge.
The surface mostly recovered in 0.196–0.204 seconds and fully recovered in 0.29–0.31 seconds, while bounce measured 11.07–11.53 inches and sinkage 1.65–1.71 inches. This is an unusually responsive all-foam surface rather than a slow memory-foam hug.
The mattress measures around 12 inches thick with roughly 5 inches of comfort material and a 7-inch high-density support core. Product-specific long-term public reports remain too limited to establish how quickly the foam layers may soften.
The score uses the policy terms shown in the Fine Print Check below. Models governed by the same terms use the same policy inputs.
Lull positions Lull Original Premium Mattress as a 12-inch medium-firm premium memory-foam mattress with enhanced comfort and support.
Testing supports the broad role, with pressure relief around 8/10 and support around 8.8/10, but body weight and position still decide fit.
The shallow medium-firm contour is strongest for back and combination sleepers; pressure-sensitive side sleepers and stomach sleepers over 230 pounds should compare a different feel.
Lull highlights gel-infused open-cell foam and quick-response support foam.
Cooling scored 7.8/10, and ease of movement scored 10/10.
Hot sleepers and combination sleepers should prioritize the measured traits instead of broad category claims.

Quilted memory foam coverOpen-cell memory foam cover
Lull describes a quilted memory-foam cover with open-cell foam and a hexagonal stitch pattern for breathability. This quilted surface supplies the first stage of cushioning before the sleeper reaches the foam or spring layers below, while its fibers can also influence moisture and surface airflow.
Why it matters: Across the Lull Original Premium Mattress, pressure-relief testing scored 8/10. A thicker quilt can soften initial contact, but deeper pressure relief and alignment still depend on the complete comfort and support stack.
Cooling comfort layer2" gel-infused memory foam
The mattress uses a 2-inch cooling-gel bead memory-foam layer for pressure relief and heat redirection. Memory foam conforms under sustained load, spreading pressure over a larger contact area. Its thickness and position influence contour depth and how quickly the sleeper reaches firmer layers below.
Why it matters: For the Lull Original Premium Mattress as a whole, pressure-relief testing scored 8/10. This is one of the layers most responsible for shoulder and hip cushioning; sleepers who dislike a close contour should compare it with the mattress’s recorded sinkage and recovery.
Fast response transition layer2" high-resilience medium-firm foam
Lull describes this layer as proprietary high-resilience foam designed for contouring support, motion distribution, and alignment. This layer buffers the sleeper from the firmer support core and controls how gradually resistance increases as the body sinks deeper.
Why it matters: In the finished Lull Original Premium Mattress, sinkage measured around 1.68″. It becomes especially important for higher-weight sleepers and back or stomach sleepers, who engage more of the mattress depth than lighter sleepers.
Support core7" high-density foam
The mattress uses a 7-inch sink-resistant high-density foam base layer. This foundation resists deep compression and keeps the comfort layers working on a stable plane; it is not intended to provide the mattress’s initial plushness.
Why it matters: Across the Lull Original Premium Mattress, the construction includes a 7-inch high-density foam support core. Its thickness and material quality are more relevant to long-term shape retention and bottoming-out resistance than to surface softness.
Outer coverPremium fabric cover
Lull describes the outer cover as high-quality fabric with subtle channel stitching. As the surface textile, it chiefly affects the initial hand feel, moisture movement, and how readily heat leaves the sleeper; it supplies little of the mattress's deep support.
Why it matters: For the Lull Original Premium Mattress as a whole, cooling testing scored about 7.8/10. Treat the cover as one part of thermal comfort rather than proof that the mattress will stay cool for every sleeper.
