Is the Lull a Good Mattress for You? 

Before I get into my full review, let’s answer the most important question: Is the Lull right for your needs? The Lull is an all-foam mattress with a softer-than-average feel, making it a great fit for a select group of sleepers. 

Who I recommend the Lull Mattress for

  •  I think this mattress would be great for back sleepers. it offers a mix of pressure relief and spinal support. The memory foam comfort layer provides some body contouring, while the firmer poly foam layers help elevate the hips in line with the spine.
  • This could also be a great choice for side sleepers, because the memory foam comfort layer provides pressure relief around the shoulder and hip. At the same time, the firmer poly foam layers help maintain side sleeping spinal alignment.
  • Folks who love memory foam will find many of the material’s characteristics at play in this bed: It offers some body-contouring, sinkage, and pressure relief.

Who I don’t recommend the Lull Mattress for

  • Stomach sleepers might not get enough support on this mattress. It’s likely that your hips will sink into the bed, throwing the spine out of alignment. Strict stomach sleepers will probably want to look for something firmer.
  • Heavier folks (250 lb and up) also might not find enough support on the Lull, because its all-foam construction isn’t exceptionally sturdy. It also doesn’t have great edge support, so larger folks won’t be able to utilize the full surface of the mattress.

How Firm is the Lull mattress?

Now that we have an overview of the Lull mattress, let’s go over its firmness and feel. 

Firmness can be dependent on a person’s body type and preferred sleeping position. Because of that, we like to poll a range of folks at Sleepopolis to rate the firmness of a mattress.

Lull Mattress Firmness
I found the Lull mattress to have a medium firmness

After laying and rolling around on the bed, I ranked the Lull a 6 out of 10 for firmness. The industry standard for medium firmness is 6.5, so the mattress is just a touch softer than medium firm.

Understanding the Lull’s construction helps us make sense of why it feels a hair softer than medium firm. The mattress combines soft memory foam with firmer poly foams, which creates a balanced feel that’s right around the middle of the firmness scale. This could appeal to back and side sleepers, because both sleep positions require a bit of pressure relief combined with support for spinal alignment.

Lull Mattress Performance 

While firmness is helpful to know when choosing a mattress, there are other important factors to consider. I also tested for pain relief, support, support in different sleeping positions, and more.

Testing the Lull Mattress in Different Sleeping Positions

Different sleeping positions and weights need different amounts of support. Take a look at whether the Lull could work for yours. 

Is the Lull a Good Mattress for Light Sleepers (Under 130 lb)?

  • Light Back Sleepers – Light back sleepers should feel great on the Lull! The firmer poly foam layers will do a great job keeping their spines in a nice even alignment in this position.
  • Light Side Sleepers – The Lull would be a decent option for light side sleepers. I don’t think they’ll feel pressure building up at the shoulder or hip. 
  • Light Stomach Sleepers – The Lull would not work well for light stomach sleepers. It doesn’t offer enough support to keep their hips lifted up in line with their shoulders.

Is the Lull a Good Mattress for Average Weight Sleepers (130 – 250 lb)? 

  • Average Weight Back Sleepers –  The Lull should feel wonderful for these sleepers! Its foam support system will help keep their spines in an even alignment in this position.
  • Average Weight Side Sleepers – Average weight side sleepers should like the Lull, especially if they alternate between their side and another position at night. 
  • Average Weight Stomach Sleepers – These sleepers will likely find their hips sinking too far into the mattress. I’d recommend average weight stomach sleepers search for a firmer option. 

Is the Lull a Good Mattress for Heavy Sleepers (over 250 lb)? 

  • Heavy Back Sleepers – This mattress won’t provide enough support for heavy sleepers. I’d recommend these sleepers check out our Best Mattress for Heavy People review for better options. 
  • Heavy Side Sleepers – See above. 
  • Heavy Stomach Sleepers –  See above.

Lull Mattress Pain Relief Performance

Pressure relief is how a mattress can help alleviate tension at the shoulders, hips, and lower back. It’s important for all sleepers, but especially for those who experience pain at night or the next day. I’m going to use a pressure map to test out the Lull mattress’ pressure relief. 

The test works by rolling out a pressure map on the mattress and laying on it. As I move into different sleep positions, the map records how much force I’m exerting on the mattress. It ultimately shows a colored “map” of the pressure. The color blue on the map shows low pressure and red shows high pressure.

Lull Mattress Pressure
Pressure map test results for the Lull mattress

Back Pain – When I’m on my back, my weight feels evenly distributed. I sink into the comfort layer a bit and feel some nice contouring around my body. At the same time, the firmer poly foam layers keep my hips elevated and aligned with my spine. They also keep my whole body elevated enough that I don’t feel stuck in the bed. This shows it’d be a good choice for back sleepers who like a mattress with a gentle feel.

Shoulder Pain – The Lull had impressive pressure map results when it came to my shoulder. It showed no pressure building up in that area. I felt comfortable laying on my side with enough support. This should be a good option for most side sleepers, unless you have sensitive joints. 

Hip Pain – The hip is a common hot spot for sleepers, but the Lull doesn’t show much pressure building up in the area for me. This makes it a good option for side sleepers or combo sleepers who switch between their side and back. However, if you have sensitive joints and are a side sleeper, it might be better to opt for a mattress with an additional layer of memory foam for better support.

Lull Mattress Performance for Couples

If you sleep with a partner, you should  consider a few additional factors that single folks might not have to worry about. You’ll likely want a mattress with motion isolation, mobility, cooling properties and edge support. Read below to see why and how the Lull performs in these categories. 

Motion Transfer 

As with pressure relief, motion transfer impacts whether a mattress matches your sleep needs. This term refers to whether you’ll feel a sleeping partner’s movements if they shift around during the night. It’s extra important to consider motion transfer if you share a bed with a partner, child, or pet!

To test motion transfer on the Lull, I dropped a 10 lb steel ball from 4 inches, 8 inches, and 12 inches. These heights mimic various movements, from tossing and turning to getting out of bed or jumping on top of it. Next, I measured the disturbance caused by each of these drops. The bigger the lines, the bigger the disturbance!

Lull Mattress Motion Transfer
I was impressed with the Lull mattresses ability to isolate disturbance

After looking at these results, I’d say the bed performed about average overall. It did a decent job of isolating smaller movements, but you’re still going to be disturbed if a dog or kid jumps into bed during the night.

Sex

Typically, a fairly responsive mattress is  ideal for sex. That way it’s easy to move around and change positions. The Lull has both memory foam and firmer poly foams, which allow it to be responsive. It should be a nice option for couples looking to move around rather easily. 

Cooling 

Sleeping with a partner can cause you to overheat, so it’s important for a lot of couples to have a cooling mattress. The Lull uses  gel in its foam layer, which helps to dissipate heat. Overall, it sleeps pretty cool for an all-foam mattress. Most couples and hot sleepers should be comfortable on this mattress. 

Edge Support

Edge support shows whether or not you can sleep near the side of a bed without it collapsing or sagging beneath your weight. A strong edge is helpful when trying to use the full surface of the mattress, which is typical for couples sharing the space. Because of its all-foam construction, the Lull isn’t exceptionally sturdy. I felt the Lull had slightly below average edge support. 

What is the Lull Mattress Made Of? 

The Lull is an all-foam bed that uses a combination of memory and poly foams to create a balanced feel. But these aren’t your everyday foams. The memory foam is infused with gel to help dissipate heat, and all of the foams are CertiPUR-US Certified, meaning they’re free of a variety of harmful chemicals.

Intrigued? Let’s take a gander at what’s inside the Lull!

Cover – First up, you’ll find a cover made from a polyester blend that has a durable, cozy feel.

Comfort Layer – Beneath the cover, there’s a comfort layer made from 1.5” of gel-infused memory foam. In classic memory foam fashion, this layer has a slow response to pressure, allowing sleepers to sink in for some body-contouring and pressure relief. Meanwhile, the gel infusion helps draw heat away from the sleeper.

Transition Layer – Next up is another 1.5” foam layer, but this time it’s made of poly foam. It’s a little firmer and has a quicker response to pressure than the memory foam above it. This layer helps balance out the softness of the memory foam, creating a mix of support and comfort that could appeal to back and side sleepers.

Base Layer – Finally, you’ll find 7” of high-density poly foam. This material is firmer than all the layers above, and it helps provide support and structure for the mattress.

Lull Mattress Unboxing and Off-Gassing

Similar to most bed-in-a-box mattresses, the Lull does release a bit of a chemical smell once it’s opened. This process is known as off-gassing. However, the odor should go away within 24-48 hours, and is no stronger than the smell of a typical box mattress. Unboxing the Lull is pretty easy. This bed isn’t overly heavy or difficult to take out of its box. 

The foams in the Lull mattress are CertiPUR-US certified, which means they’re free of a variety of harmful chemicals, including formaldehyde, heavy metals, and ozone depleters. These foams also minimize strong smells coming from the mattress.

My Final Thoughts about the Lull Mattress

Now that we’ve made it through all the tests, I want to go over who would benefit most from the Lull mattress and who might want to look for another option.  

My favorite things about the Lull Mattress

This is an all-foam mattress that would be great for couples. This bed has great motion isolation so you will not feel your partner tossing and turning at night. I think it’s a particularly great bed for r lightweight and average weight back sleepers, as it provides an ideal mix of pressure relief and support. 

I also thought the Lull did a good job at preventing sleepers from overheating, which some memory foam mattresses can be prone to. Hot sleepers and couples should appreciate this mattress’s cooling features.

My Lull Mattress complaints 

I would not recommend the Lull mattress to stomach sleepers or heavy sleepers (over 250lbs). It doesn’t provide enough support for these sleeper types. When I tested it out on my stomach, my hips sank too far into the mattress, which threw my lower spine out of alignment.

Lull Mattress Policies and FAQs

Does Lull offer a mattress warranty?

All Lull mattresses come with a lifetime warranty.

Does the Lull come with a sleep trial?

Yes, Lull offers a 365-night trial period with this bed. If you decide you don’t like your Lull within this period, you can return it for a full refund.

Do you need a box spring with the Lull?

No. The Lull, like many mattress-in-a-box beds, is designed to work on a slatted bed frame and doesn’t require a box spring. That said, if you already have a box spring or you prefer to use one, feel free to do so.

Can you flip a Lull mattress?

No, you should not flip a Lull mattress. The support layer is on the bottom, so if you did flip it, you’d be sleeping on a super-firm surface. If you’re worried about wear, aim to rotate your mattress 180 degrees approximately every six months.

Lull Mattress Vs  

If you’re looking at the Lull, then you might also be considering other popular online mattresses. So let’s compare the Lull to some of its mattress-in-a-box competitors here!

Purple

  • While the Lull is an all-foam mattress, the Purple uses a proprietary hyper-elastic polymer in its comfort layer. You won’t find this unique material in any other mattress.
  • The Purple’s hyper-elastic polymer creates a medium firm feel and balances support with pressure relief, much like the Lull. The hyper-elastic polymer is bouncier than the Lull’s foams, so you’ll enjoy more springness and mobility on the Purple.
  • While the Lull uses gel to dissipate heat, the Purple’s temperature-neutral polymer does an even better job of sleeping cool. It could be the better choice for folks who are prone to overheating.
  • Like the Lull, the Purple is probably best suited to back and side sleepers thanks to its balance of support and comfort.
    The Purple is more expensive than the Lull.Has the Purple piqued your interest? Learn more about this mattress in our detailed review!

Nectar

  • Like the Lull, the Nectar is an all-foam bed that uses memory foam for comfort.
  • While the Lull has 1.5” of memory foam, the Nectar has nearly 5” of this material. There’s more room to sink into the Nectar, and it’s maybe a touch softer than the Lull.
  • Thanks to its thick memory foam layers, the Nectar could be an especially good match for side sleepers, who need plenty of pressure relief around the shoulder and hip.
  • Memory foam lovers might really appreciate the Nectar, because it uses a ton of this material. It offers classic memory foam characteristics such as body contouring, sinkage, and pressure relief.
  • The Nectar and Lull are fairly comparable when it comes to price.Need to know more about the Nectar? Check out our full review!
