The Lull mattress is an all-foam, medium firm mattress with three layers: a comfort layer made of gel-infused memory foam, a transition layer made of latex-like polyfoam and latex, and a support core made of high density polyfoam.

With the three separate layers working together, the Lull conforms to the body and provides pressure relief without too much of the “sinking” feeling that you get from memory foam. The high density core also provides lumbar support and promotes spinal alignment, which helps with back, hip, and neck pain. At a lower than average price point, this flagship product from the Lull brand is a great new addition to the bed-in-a-box market.

How Much Is the Lull Mattress?

As mentioned above, the Lull mattress has a lower than average cost point for an all-foam bed-in-a-box mattress. The mattress isn’t exactly cheap, but it’s definitely reasonably priced. Add-ons such as bed frames and foundations could increase your total, but the Lull still falls on the less expensive end of the spectrum when it comes to pricing.

How Does the Lull Mattress Feel?

The Lull has a medium-firm feel, about a 6 on the 1 to 10 scale, which gives you a good balance of contouring and support. When you first lie down on the mattress, you can definitely feel the softness of the memory foam comfort layer taking the pressure off of your hips, shoulders, and neck. However, due to its polyfoam transition layer, the Lull doesn’t sink too deeply, nor does it give you that feeling of being “stuck.” The high-density foam core provides noticeable support and distributes body weight evenly throughout the surface of the mattress, which takes pressure off of the back and keeps the spine straight. You can definitely feel the combination of support and cradling from the get go.

What Is the Lull Mattress Made Of?

Cover Material

The Lull’s cover is made from a polyester rayon blend. It’s durable, but still soft and cozy.

Comfort Layers

The first layer of the mattress is 1.5 inches of gel-infused memory foam. This layer offers the classic conforming and pressure relief of classic memory foam, with added heat dispersal and cooling to keep the mattress from sleeping too hot.

Transition Layers

The transition layer of the Lull is 1.5 inches of blended polyfoam that has a feel similar to latex. This layer is firmer than the comfort level and has a quicker response to pressure. This moderates the sinking feel of the mattress while evenly distributing weight and providing additional support.

Support Core

The support core of the mattress is 7 inches of high-density polyfoam. This core serves as the base of the mattress, and is much firmer than the comfort and transition layers. It provides support, prevents sagging, and maintains the structural integrity of the mattress.

Does it Isolate Motion?

Rating 3/5

The Lull does a pretty good job at isolating motion.

Motion isolation refers to how well a mattress keeps motion on one part of the bed from being felt by a person on another part of the bed. A mattress with good motion isolation is particularly important for couples, especially if one or both people are light sleepers.

In general, memory foam tends to isolate motion well. The Lull performs quite well when it comes to isolating smaller movements, and performs about as well as most other memory foam mattresses when it comes to isolating larger movements. You’re unlikely to feel your partner move on their side of the bed, for instance, but you may feel a child jumping up and down at the end of the bed. In general, though, the Lull keeps motion transfer to a minimum, and should keep most sleepers, even light sleepers, from disturbance during the night.

Does the Lull Mattress Sleep Cool?

Rating 3/5

The Lull sleeps moderately cool.

Memory foam is notorious for trapping body heat and sleeping hot. This is because of the density of the material, and the way it contours to the body. However, the top layer of memory foam in the Lull is injected with cooling gel. The gel helps to keep heat from collecting near the sleep surface..

This added feature keeps the Lull relatively temperature neutral. That is, it keeps the sleep surface from getting too hot, but it does not actively cool. This is enough to keep most people comfortable. However, if you’re a particularly hot sleeper, you may want to seek out a mattress with materials and features that better aid in cooling.

Will It Sag Along the Edges?

Rating 3/5

The Lull has edge support that’s about average for a memory foam mattress.

Edge support refers to how well the edges of the mattress support your weight, either while sitting or lying down near the mattress edge. Edge support is especially important for people who want to utilize all of the surface area of their bed (including couples), and people who tend to spend time sitting on the edge of their bed.

Most all-foam mattresses, especially when they incorporate memory foam, have issues with edge support, and sag when people put pressure on the edges of the bed. Like its counterparts, the Lull doesn’t stand out when it comes to edge support, and you’ll experience some sinkage. This isn’t a big deal for all sleepers, but will likely be more of an issue if you sleep near the edge and are more than 230 pounds.

Is It Good for Sex?

Rating 3/5

When it comes to sex, the Lull has its pros and cons, but it is generally a sex-suitable mattress.

As an all-foam mattress, the Lull is basically silent, which is great for discretion. However, the Lull has limited bounce, and it’s relatively difficult to move from one part of the mattress to another, which makes changing positions a little onerous.

What About Off-gassing?

Rating 3/5

The Lull has around the same amount of off-gassing as other bed-in-a-box foam mattresses.

When foam mattresses are first unpacked, they often give off a distinct chemical odor. This odor comes from the release of VOCs (volatile organic compounds), which are manufacturing byproducts. This is referred to as “off-gassing.” Though VOCs are harmless, the odor can be somewhat unpleasant, especially to people who are sensitive to smells.

The Lull does tend to let off a slight chemical smell when it is first unpacked from the box. However, the Lull does not have a particularly bad off-gassing problem when compared to other all-foam bed-in-a-box mattresses. According to reviews, the smell usually dissipates within a few hours and doesn’t linger on noticeably.

What Type of Sleeper Is the Lull Mattress Best for?

The Lull mattress is suited to a number of different sleeping positions, but it generally works best for back and side sleepers, especially those under 230 pounds.

Side Sleepers

People who sleep on their sides generally seek out mattresses with a good deal of cushioning and contouring, so as to relieve pressure on the hips, shoulders, and neck. The Lull’s top comfort layer provides that memory foam hug and takes the weight off of common side-sleeper pressure points. This mattress is a good pick for the average side sleeper.

Stomach Sleepers

Some stomach sleepers may not get enough support from this mattress. People who sleep on their stomachs tend to need a firmer mattress, in order to keep their hips from sinking into the bed and throwing their lower back and spine out of alignment. This is especially true for stomach sleepers who are over 230 pounds. For a stomach sleeper in that weight class, the Lull is not the right choice. Strict stomach sleepers under 230 pounds might also want to consider a different mattress, as the Lull may not have enough support for your needs.

Back Sleepers

The Lull is also great for back sleepers, since the contouring of the comfort layer is balanced by the support of the transition and foundation layers. Back sleepers need that support to keep their hips elevated and their spines in neutral alignment as they sleep. The support-comfort combo offered by the Lull should suit most back sleepers well.

How Does Body Weight Impact the Lull Mattress's Performance?

Put simply, the Lull is probably not a good pick for people who are over 230 pounds. Because it’s all-foam, 10 inches thick, and relatively lightweight, it will not offer the right level of support for those who are 230 pounds and above. This is especially true over time: while the mattress may be fine for a person in that weight class in the short term, using it as a primary bed long term may cause aches, pains, and disturbed sleep.

People who are 230 pounds and above would be better served by picking a different mattress altogether, specifically one that is firmer, thicker, heavier, and more supportive.

Is the Lull Mattress Good for Couples?

The Lull Mattress is suitable for couples.

This mattress has a few things going for it when it comes to couple-friendliness. The Lull does a good job at isolating motion, which is one of the most important factors to consider when buying a mattress as a couple. In addition, couples may enjoy the features of the mattress that make it adequate for sex, such as traction and a lack of noise.
