We track the Queen Lull Original memory-foam mattress alone.
Pick one or more traits above and we will show the strengths and watch-outs that matter for this mattress.
Buy the Lull Original if you want a straightforward foam mattress for back sleeping, combination sleeping, or a firmer-feeling value pick. Skip it if you are a pressure-sensitive side sleeper, sleep very hot, or want a return policy without a processing-fee caveat.
Pressure relief scored 6.8/10. Sinkage measured 1.44–1.50 inches and the measured comfort layer was about 3 inches, so the Original feels more support-forward than plush. Back sleepers are the clearer fit; side sleepers with sensitive shoulders or hips should compare thicker or softer foam beds.
Support and alignment scored 8.9/10. The mattress has shallow sinkage and a 10-inch memory-foam build with a 7-inch high-density foundation. That is why it is more convincing for back sleepers and some combination sleepers than for pressure-sensitive side sleepers.
Motion-transfer testing scored 7.6/10, with peak-to-peak acceleration 11.08–11.54 m/s². That result indicates noticeable partner movement, so very motion-sensitive 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 scored 7.8/10. Lull lists OpenCell memory foam and gel-infused cooling foam, and shallow sinkage helps limit surface contact, but this is still an all-foam mattress. Very hot sleepers should compare hybrids or more cooling-focused foam beds.
Edge support scored 9/10, with 3.43–3.57 inches of sitting-edge compression and an Excellent lying-edge result. That is a real strength for a foam mattress and helps couples use more of the surface.
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, fully recovered in 0.29–0.31 seconds, and measured 12.56–13.08 inches of bounce. It should feel easier to reposition on than slower, deeper-sinking memory foam.
The 10-inch memory-foam construction has about 3 inches of measured comfort material over a high-density support core. Owner complaints provide risk context and are not assumed to apply universally; long-term evidence remains limited.
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 the Original as a medium-firm memory-foam mattress for pressure relief, support, and cooler sleep.
Testing supports the broad role, with pressure around 6.8/10 and support around 8.9/10, but body weight and position still decide fit.
The shallow, slightly firm foam surface is strongest for back and combination sleepers; pressure-sensitive side sleepers and stomach sleepers over 230 pounds should compare a different feel.
The model is marketed through its materials, airflow, surface feel, or support design.
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
Lull describes a quilted memory foam cover with open-cell foam and a hexagonal stitch pattern for airflow. 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 Mattress, shallow contour can suit back sleepers who prefer minimal sink. A thicker quilt can soften initial contact, but deeper pressure relief and alignment still depend on the complete comfort and support stack.
Gel-infused cooling memory foamMemory foam with cooling gel
The mattress uses 1.5 inches of gel-infused memory foam intended to contour and move heat away from the body. 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 Mattress as a whole, shallow contour can suit back sleepers who prefer minimal sink. 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.
Therapeutic mid-layerHigh-resilience foam
Lull lists 1.5 inches of high-resilience foam to deepen contouring while limiting excess sinkage. This foam distributes load through the comfort stack. Its position, thickness, and firmness matter more than a gel infusion or branded name alone when judging contour and support.
Why it matters: In the finished Lull Original Mattress, shallow contour can suit back sleepers who prefer minimal sink. Near the surface it contributes more cushioning; deeper in the mattress it primarily moderates the transition into the support core.
High-density foam foundationHigh-density foam
The mattress uses a 7-inch foam foundation for durability and support. 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 Mattress, the memory-foam build has a defined comfort layer over a support core. Its thickness and material quality are more relevant to long-term shape retention and bottoming-out resistance than to surface softness.
Premium coverChannel-stitched fabric cover
Lull describes a high-quality fabric cover finished 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 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.
