Help me to welcome in the new Lull mattress! Lull is a 10″ all foam mattress designed to fit into the universal comfort feel. While Lull prioritizes supportive comfort and cooling, they have created a mattress they believe will fit the needs of most sleepers.
Does the Lull actually meet those standards? We put it to the test in this week’s mattress review! Continue reading below to find out!
A top layer of gel infused memory foam helps the Lull mattress stay cool and breathable — a good pick for hot sleepers!
The Lull mattress is a 10″ memory foam mattress built from 3 separate foam layers.
- Top layer (cooling & comfort) – 1.5″ of gel infused memory foam. This layer is designed to provide great cooling on the sleeping surface of the mattress, while also creating comfort by relieving pressure points for sleepers.
- Middle layer (support) – 1.5″ of conventional foam. This transitional layer works to support the body while maintaining proper spinal alignment and even weight distribution. The combined densities of the top and middle foam layer help to ensure great support for both light, average, and heavier sleepers.
- Bottom layer (foundation) – 7″ of dense support foam. This layer acts as the foundational base for the mattress and provides a strong, stable, and dense foundation that works with the top layers to create great support.
The Lull’s cover mixes a modern look with a soft feel.
Although the cover may not seem like an important piece of the mattress, it can be just that. Covers help to improve breathability and cooling, while also providing a soft to the touch feel. Made from 90% polyester and 10% rayon, the Lull’s cover has a soft feel. While polyester is very lightweight, it does not lack durability either. The cover of the Lull is highly elastic. Even after a fairly abrasive tug on the cover, it was able to return to its original shape almost immediately. Additionally, this cover can be easily removed for spot cleaning.
Aesthetically, the cover has what has become the standard two-tone design, with grey side panels and white fabric on top. The side panels are built from 64% polypropylene and 36% polyester, this gives them a great resiliency to damage. I quite like the dark navy strip that divides the white fabric from the grey side panels, it’s a subtle touch that helps give the Lull mattress a clean style.
Firmness, Feel, & Support
The Lull mattress has firmness somewhere between a medium and a slightly firm feel. It’s a mattress designed to meet the needs of almost any sleeper. On the firmness scale, the Lull comes in at a 6-6.5 out of 10, with 10 being the most firm.
With regards to overall feel and support, the Lull is well above average. As a stomach and side sleeper, I found the mattress to be very supportive. I received the same response from my wife, who sleeps mainly on her side and back.
The Lull’s foam layers work well together to provide that balanced push-back feel, while not creating pressure points. The Lull rides a very fine line in this respect. If you go too firm then you may find yourself tossing and turning while trying to relief pressure, too soft and you can find a lack of proper support creates its own problems. I’m impressed the Lull is able to deliver the slightly firm feel without going too far along the firmness spectrum, leaving it close enough to the middle that it finds a balanced feel suitable to the majority of sleepers.
A huge plus for me was the minimal amount of motion transfer I saw while sleeping on the Lull. The top 2 layers of foam do a great job of dissipating most of the motion throughout the night. However, the Lull does not have instantaneous response. The foams are not extremely slow, but they do not hop right back into shape immediately after pressure is applied.
That said, the Lull’s slightly firm feel helps in this area also. Since there is not a dramatic hug with the mattress there isn’t as critical of a responsive need. Despite the slower response times I did not ever feel trapped or otherwise enveloped by the foams.
The edge support is above average. The 3 layers of foam do a great job supporting you while lying or sitting on the edges of the mattress. This is a positive attribute for those sleepers who prefer to sleep closer to the edge, or for amorous bedroom activities!
Additionally, bounce plays a role when talking about amorous bedroom activities and general mattress comfort. The Lull’s slightly firmer feel helps create a reasonable amount of bounce. It’s a sizable step up from traditional memory foam, but if you’re comparing it to a coil mattress it’s going to be less than this. I would say the bounce is slightly above average when compared to most other 10″ foam mattresses.
Every mattress reviewed on Sleepopolis goes through a quick series of sinkage tests. These tests are designed to offer a comparison against other mattresses in addition to determining how it will perform under various conditions, pressures, and positions.
- Lying on back – in a normal lying position where my weight was evenly spread across the mattress, I saw 2″ of sinkage.
- Lying on side – while lying on my side, I saw closer to 2.5″ of sinkage.
- Sitting on edge (conservative) – while sitting on the edge with my butt scooted back onto the mattress I saw about 3″ of sinkage.
- Sitting on edge (aggressive) – with all of my weight placed on the edge (in a sitting position) I saw 5″ of sinkage.
- Standing in middle – while placing all of my weight at one point on the mattress I saw 5.5″ of sinkage.
Keep in mind, sinkage will vary based upon body weight. As a reference point, I weigh 140 pounds.

The big bottom line question, who is the Lull mattress best for?
I would recommend the Lull mattress to sleepers who:
- Prefer a medium to slightly firm feel – sitting at a 6-6.5 out of 10 on the firmness scale, where 10 is the most firm, the Lull has a medium to slightly firm feel. Many times mattresses that venture beyond a 6 out of 10 can create pressure points or too much of a “floating on top” of the mattress feel. Even with a 6-6.5, the Lull creates great pressure relief, a slightly firm feel, and consistent support.
- Want a cool mattress – built with a 1.5″ top layer of gel infused memory foam, the Lull does a good job of preventing heat retention in the mattress. The slightly firm feel helps in this area by preventing any type of “stuck” feeling for sleepers. The Lull is well above average with regards to cooling and is significantly better than most traditional memory foams.
- Want minimal motion transfer – designed with 3 layers of foam, the Lull does a great job of handling motion. The top 2 layers of foam work together to dissipate much of the the motion, preventing major disturbances during the night.
Slightly Firm Feel + Great Support
- Edge Support
Lull features a 10-inch, all-foam design with a memory foam comfort layer. Our testers all rated the Lull as having a medium firmness when it comes to feel. We also thought the Lull did a good job at preventing sleepers from overheating, which some memory foam mattresses can be prone to.
