Ranked #6 on our Best Affordable Memory Foam Mattress list
The wallet-friendly Lull Mattress is an all-foam model distinguished by excellent motion isolation and pressure relief. Balanced, medium firm construction should appeal to side and back sleepers across different weight groups.
- Good for side sleepers and lightweight sleepers
- Good motion isolation reduces night time distubances for couples
- Relatively inexpensive
- May not provide enough support for heavier back and stomach sleepers
- Foam layers tend to trap body heat throughout the night
Lull launched with the goal of providing premium sleep solutions at an affordable price. Its product line includes bed frames, bedding, and a mattress.
The Lull Mattress is constructed entirely of foam, including memory foam, conventional foam, and polyfoam. This construction is engineered for support, pressure relief, motion isolation, springiness, and breathability.
We’ll cover the mattress’s construction, performance, pricing, sizing, reviews, and policies. If you’re considering purchasing a Lull Mattress, keep reading to learn more and decide if it’s a good choice for you.

TEST LAB RATINGS
How the Lull Scored
Motion Isolation7.0/10
The Lull’s relatively thin comfort layer, coupled with the bounce of its transition layer, leads to slightly more motion transfer than some all-foam models.
While the 1.5-inch layer of memory foam absorbs some motion, thicker comfort systems tend to isolate motion to a greater extent. Since the transition layer has a latex-like quality to give the bed more bounce, this could also contribute to additional motion transfer.
Most sleepers are unlikely to find this motion transfer significant enough to interfere with their sleep, but individuals who awaken more easily might notice it more.
Pressure Relief7.0/10
Most all-foam mattresses have strong pressure-relieving properties, and the Lull follows this trend. Its 1.5-inch layer of memory foam adjusts to the sleeper’s body shape to support their spine while redistributing pressure from their shoulders and hips. The 1.5-inch transition layer gives deeper contouring without excessive sinkage. This strong pressure relief can help reduce aches and pains.
Temperature Control4.5/10
Like other mattresses with memory foam comfort layers, the Lull’s close conforming may trap some heat against the sleeper’s body. However, thanks to a gel-infusion, it may not sleep as hot as many all-foam models. Gel helps wick heat away to keep the surface cooler, so the Lull may be a good option for sleepers who tend to sleep hot but enjoy the hug of memory foam.
Edge Support6.0/10
Because of its relatively thin comfort layer, the Lull’s edge may feel sturdier than many other models that are constructed of foam. Sleepers do not need to sink in as far to reach the firmer foam of the transition layer and support core, which may make the perimeter of the bed feel more stable. Couples who need more mattress space and individuals who frequently sit near the perimeter of the mattress may find this stable edge particularly useful.
Perceived edge support may also depend on a person’s weight. People who weigh over 230 pounds may feel the perimeter isn’t quite as strong as they’d like, but those who weigh under 130 pounds may find it quite supportive.
Ease of Movement4.5/10
The Lull Mattress is moderately easy to move on due to its thinner comfort layer and medium firm feel. Memory foam contours closely to the sleeper and usually responds slowly to changes in pressure, which can slightly impede movement. However, the Lull uses just 1.5 inches of memory foam, so most individuals are unlikely to sink in very far. The transition layer and polyfoam core give extra support to ensure the sleeper is unlikely to feel “trapped in the bed.” Thanks to its medium firm feel, the Lull also has less hug than many memory foam models, which may make it easier to move on.
Durability5.5/10
Memory foam mattresses aren’t known for their longevity. This soft material can only compress and decompress so many times before it starts to have trouble springing back to its original shape. When this happens, you’ll start to see permanent indentations in the areas where you usually sleep, and the polyfoam core may start to dip in the middle. Similar to competing models, we anticipate the Lull to start wearing out around the five- or six-year mark.
Who it Fits
Fit by Sleep Position and Body Weight
Sizes, dimensions and weights
Side Sleepers
A memory foam comfort layer and conventional foam transition layer work together to adjust to a side sleeper’s curves. While their hips and shoulders can sink in enough to relieve pressure points, most individuals should experience enough support to keep their spine aligned.
Side sleepers who weigh 230 pounds or less are most likely to experience a strong balance of cradling and support. Individuals who weigh over 230 pounds may sink in a little more deeply, especially around their hips. Because of this, they could experience more pressure points and they may find it more difficult to maintain their spinal alignment.
Back Sleepers
The Lull’s medium firm feel contributes to an even plane that may appeal to back sleepers who weigh under 130 pounds. Thanks to its relatively thin comfort layer, individuals in this weight group should not sink in very far before getting the support they need from the transition layer and polyfoam core. This should minimize sinkage near the sleeper’s hips, which may be beneficial for spinal alignment.
Back sleepers who weigh more than 130 pounds will also likely experience a relatively even surface without too much sagging near their hips. However, some sleepers may find their midsections sink in slightly more than ideal, especially if they carry extra weight in this region.
Stomach Sleepers
The Lull may not be firm enough for some stomach sleepers. Individuals who weigh over 130 pounds may experience some drooping near their hips and bellies, and this could make it harder to keep their spines aligned.
Stomach sleepers who weigh under 130 will probably experience a better blend of plushness and support. The memory foam layer cushions the surface, while the conventional foam transition layer limits the amount of sinkage.

Availability
The Lull Mattress can be shipped within the United States. It is sold on the Lull website and through Amazon. Different return policies apply to orders from Amazon.
Shipping
Lull mattresses ship free within the contiguous United States. Shipping charges apply for orders to Alaska and Hawaii, but Lull subsidizes these costs.
Mattresses usually arrive 1-4 business days after the order is placed. They ship compressed via FedEx, and customers will receive a tracking number. The box measures 21 inches by 21 inches by 44 inches, so it is approximately the size of a mini-fridge. Customers are responsible for moving the mattress to the bedroom of choice, unboxing it, and setting it up.
Lull recommends unpacking the mattress right away. It should not stay in the box for more than 3 weeks. The mattress expands primarily within the first 2-5 hours after unpacking. It should finish expanding within 24 to 48 hours.
Additional Services
At this time, Lull does not offer White Glove delivery or old mattress removal.
Sleep Trial
Lull gives customers a 365-night sleep trial to try the mattress at home. This trial does not include a mandatory break-in period of any kind. If customers choose to return the mattress, Lull will send a courier to pick it up and then issue a full refund. Returned mattresses are either donated or recycled.
Warranty
Lull has a lifetime limited warranty that vows to either repair or replace mattresses with eligible defects at the company’s discretion for as long as the original owner retains possession.
This warranty applies to the original mattress owner when purchased from an authorized distributor. To qualify, issues must not have occurred due to the use of an improper foundation, misuse, or abuse. Covered defects include indentations over 1.5 inches, manufacturing flaws in the zipper cover, and physical flaws in the cover’s construction.
Maintain a copy of your receipt and/or your confirmation email as proof of purchase. Lull bears all costs – including shipping and handling – during the first 10 years of ownership if the mattress develops a defect and needs to be repaired or replaced. After 10 years, owners pay a flat transportation fee of $75 for mattress replacements. Additional terms and conditions apply.
