Lull Mattress Review

lull mattress wood platform - SleepSharp

The Lull mattress is among the most popular beds out there, and for a couple of reasons. First, this mattress successfully fills the price gap memory foam beds create. Although it’s not dirt cheap, our review team finds it much more affordable than most high-end all-foam mattresses. 

Secondly, this mattress is giving most of its pricier competitors a real run for their money in terms of durability. In our experience with all-foam beds, affordability and longevity rarely come in the same sentence. So, that’s another big plus for Lull.

As an overview of this bed, the Lull is a 10-inch medium-firm mattress with three all-foam layers. The top layer is gel-infused, and the transition layer features a proprietary blend of poly foam and latex. Also, this mattress has a soft, breathable cover that boosts air circulation besides adding to its aesthetics. 

If you are on the fence about purchasing this bed, this Lull mattress review will tackle everything that you need to know about it, including comfort and support, heat retention, pressure relief, and durability among others.

Lull Mattress Brand Overview

lull mattress logo - SleepSharp

Lull is an online mattress brand that launched its operations in April 2015. Its founder and CEO, Sven Klein says that the main aim behind starting this line was to, one, offer a mattress that would work for everyone, and, two, make the mattress buying experience much more straightforward for everyone.

The Lull mattress is the flagship product of this brand. However, it also deals with other bedding products, including bed frames and foundations, mattress protectors, duvets, pillows, and sheets.

Before digging deeper into this mattress review, it’s worth letting you know that this bed is not entirely made in the US. Although some materials are USA-made, Lull says that they also obtain other components from China and Vietnam.

Who do we recommend it for?

Our review team thinks this is a perfect mattress for sleepers who;

  • Want a memory foam mattress without that annoying stuck-in-mud feeling– while this mattress’s comfort layer is soft, the transition layer is a blend of poly foam and latex. This gives it a unique responsiveness that makes it easy for the sleeper to turn and move around on.
  • Weigh 130 lbs to 230 lbs– the Lull mattress is a medium-firm (6.5/10) bed. In our experience, this is a sweet spot for a mattress that offers consistent support and comfort for individuals in this group without creating pressure points.
  • Want a quiet mattress with excellent motion isolation– this is an all-foam mattress, so it’s going to be very quiet in all conditions. Again, its three layers of foam act as shock absorbers to dissipate movement energy. This is what prevents the transfer of motion to the other end of the bed surface.
  • Couples– thanks to this mattress’s near-perfect balance of support and pillow-y feel, it tends to accommodate lots of people with different sleeping positions. As such, it’s a very recommendable bed for couples who don’t seem to get a mattress that works for everyone.

Lull Mattress Construction- Know why it’s different


When doing this mattress review, we liked the thoughtfulness that Lull gives to each of its components. The cover has an attractive two-tone construction design that gives it an aesthetically appealing style. The top fabric uses a blend of 90% polyester and 10% rayon. This combination makes it soft to the touch, breathable, and durable.

On the other hand, the side panels consist of 64% polypropylene plus 36% polyester. This blend gives these panels a great deal of wear resistance and resilience.

Although this cover is removable, it can’t go in the washing machine. Again, it can be a tad hard to get back. So, we highly recommend against removing it unless it’s very necessary.

Luckily, it’s very easy to spot-clean in case of spills or messes. You could also get Lull mattress cover to protect your bed from stains and minimize its exposure to allergens.

Comfort layer

The comfort layer is a 1.5-inch low-density memory foam infused with gel. Gel infusion technology is currently the epitome of pressure relief and comfort in modern foam mattresses. This layer encapsulates all the benefits of classic memory foam, such as contouring to your body lumpy bits for pressure relief. Its chief advantage, however, is its ability to boost air circulation, thereby curbing the issue of excessive heating that plagues memory foam beds. 

Transition layer

This is one of our key highlights in this Lull mattress review. The transition layer of this bed is a 1.5-inch layer made from a blend of poly foam and synthetic latex. This proprietary blend has a unique firmness that eliminates the quicksand feeling that you’d otherwise experience with the gel-infused comfort memory foam at the top.

Support layer

The support layer of this bed is a 7-inch high-density poly foam. This is the standard size for most layered memory foam mattresses on the market today. This layer is what gives you the support that you’d otherwise not get with the soft comfort and transition systems. More foam in the support core also translates to reduced sagging and durability.

What is the height of the Lull mattress?

The Lull mattress is a 10-inch bed with a 7″ support layer, 1.5″ transition layer, and 1.5″ comfort system. Going through most Lull mattress reviews, this height seems like a sweet spot for most lightweight to average weight individuals weighing up to 250 lbs.

How Firm does this mattress feel?

The Lull is a medium-firm bed that is slightly (very slightly) on the firmer side. Our mattress review team gives it a score of around 6.5 on a 1-10 soft-firm scale.

When you jump on this mattress, you’ll first feel like you’re sleeping on a cloud. In the next few seconds, you’ll experience a gradual sinking feeling as the memory foam starts hugging you. However, you wonk sink too far into the bed thanks to the medium-density latex-poly foam transition layer. As you hit the transition foam, you start experiencing a notable degree of support without the mattress being overly firm to create pressure points.

Keep in mind that our opinion above is based on what average weight folks might experience. We believe heavier individuals (above 250 lbs) will find the top layers overly soft before hitting the overly firm support base. This could pull the spine out of alignment, thereby leading to pressure points.

Performance Ratings- Lull Mattress in Action

The performance rating section in our mattress reviews sheds more light on how the bed fairs in various fronts that make a good mattress.

Temperature regulation

One of the chief advantages of memory foam is its ability to contour to your body shape for balanced support. Unfortunately, as it envelops you, it tends to create pockets that trap heat, which could lead to excessive sweating.

The memory foam layer on the Lull mattress means that this may be a potential problem. However, going through the reviews on Amazon and manufacturer website, there are very few complaints regarding overheating. We could attribute this to its breathable cover, the gel-infusion technology on its comfort layer, and its slightly firm transition layer.

Motion isolation

Motion isolation means that you can’t hear your partner or pet getting into or leaving the bed. This a key strength of foam mattresses, and the Lull isn’t left out. The layers in this mattress have lots of cells that work like a giant shock absorber. They absorb movement energy directly, thereby reducing its transmission to the other side of the mattress.


This is yet another major advantage that comes with foam mattresses. Since there are no springs or moving parts involved in the structure, this mattress does not create noise regardless of what you’re doing on it.

Edge support

Most all-foam mattresses struggle with edge support. So, it’s not surprising that this is one of the areas that the Lull mattress gets the lowest marks. Edge support becomes a big issue, especially if you spend a lot of time sitting on the side of your bed. However, we don’t think this will present any problem even when lying along the edge.


Memory foam mattresses like Lull tend to get bad press when it comes to sex. Most people highlight the lack of bounce and the likelihood of sweating like crazy. While we can’t dispute this, we believe sex on this memory foam has its upside too.

First, memory foam allows you to try out new sex positions when you feel like getting creative. Secondly, its gel-infused top layer and breathable cover will go a long way in keeping you cool. In terms of bounce, we believe this boils down to personal preference. If you prefer a high-efficiency bed with minimal bounce, the Lull is an incredible choice.

Pressure relief

Similar to other memory foam mattresses, the comfort layer of the Lull will mold around your body and hold you in a neutral position. It will also align your spine, neck, and back to relieve pressure points and prevent pain in sensitive areas. 

Our team of mattress review experts notes that the gel-infusion technology in this mattress will further improve your sleep by dissipating body heat away from you. This reduces the urge for frequent turns, which results in a deep sleep full of rest. In addition, the proprietary transition layer comes in handy to minimize excessive sinking into the mattress. 


The Lull is a synthetic memory foam mattress, so you should expect a chemical smell after removing it from its package. However, if its CertiPUR-US certification is anything to go by, then there’s nothing to worry about this smell. If anything, current users report that this odor isn’t overwhelming, and that it vanishes in a day or two.


The Lull is a relatively well-built mattress that we expect to hold up for quite some years. Although it’s not going to eclipse a high-end innerspring, we bet lightweight to average weight individuals will get 6-7 years of comfortable sleep out of it. This isn’t bad for a mattress that costs what the Lull does.

Lull Mattress vs. Your Weight and Sleeping Position

Light sleepers- less than 130 lbs

Most lightweight sleepers below 130 lbs tend to prefer a softer mattress in the range of 5 to 5.5 on the firmness scale. With a firmness level of 6.5, we believe the Lull will feel a little bit firmer for lightweight folks, especially side sleepers. However, for stomach and back individuals who prefer a firm bed, this one may be a good bet. 

Average weight sleepers- 130 lbs to 230 lbs

People in this weight group tend to enjoy the Lull much better than anyone else. Whether you sleep on your side, back, stomach, or a combination of these positions, the soft comfort layer will cradle you comfortably as the transition, and base layers offer optimum support. Keep in mind that this isn’t a firm mattress. Therefore, it might not impress you if you prefer the feeling of sleeping on a rock. 

Heavyweight sleepers- above 230 lbs

We’ve heard reports from heavyweight users who claim to like this bed. Well, it might work for some quick naps, but we’d never recommend it for your main bed. Heavyweight folks are going to collapse onto the firm base layer and, therefore, won’t get enough support. This could throw the spine, neck, shoulder, and hips out of whack, consequently leading to back pains, pressure points, and of course, nights full of inadequate sleep.

Lull Mattress Return and Return Policy

The Lull is a bed-in-box style mattress. Setting it up is straightforward. It only requires you to get the mattress out of the box and remove the plastic packaging. The mattress will expand to full size in less than 10 seconds. 

After setting it up, you’ll have 100 nights to try out the mattress and determine whether it’s perfect for your needs. In case you are not impressed within the trial period, Lull promises to refund all your money, and they won’t charge any shipping fees. Read more about Lull return and refund policy here

Lull Mattress Warranty Analysis

A large percentage of Lull mattress buyers tend to keep it after the trial period. Your relationship with Lull does not end there, though. They’ll go ahead to back your mattress with a 10-year limited warranty. This warranty covers manufacturer-related defects, including an indentation or sag exceeding one inch, manufacturing defect in the mattress cover zipper, and physical flaws on the cover resulting from faulty construction. 

In case of any of these issues, the manufacturer will either repair the defect or replace the mattress with a comparable model.

Regular Complaints about Lull Mattress that we’ve come across

  • Mattress not supportive enough -As we noted earlier on in this mattress review, the Lull may not offer enough support to people above 250 pounds. Its 10-inch thickness and medium-firm setting isn’t the right combination for this category of sleepers. Heavy folks tend to prefer thicker beds (12″ and above) with a firmer feel (at least 7.5). 
  • Mattress is too hard – This complaint mostly comes from lightweight individuals. People who weigh below 150 lbs won’t have enough force to push through the comfort layer. The mattress will, therefore, feel firm for their liking. We recommend a softer bed (5/10) to individuals in this group. 
  • Mattress sleeping hot – Yes, some folks, especially those who tend to sleep overly hot may find it warmer. However, the gel technology in the memory foam layer and the breathable cover does help in boosting air circulation compared to non-gel all-foam beds.
  • Chemical smell lingering for a long time – As a synthetic mattress, you may continue to smell a faint odor some days after the initial new mattress smell. This is common, and it will disappear too. If you wish to hasten this process, though, airing the mattress outside is a surefire way of doing this. Pouring baking soda directly on the mattress, followed by vacuuming, also helps a big deal. 
  • Mattress can’t be flipped – Fortunately, or unfortunately, you can’t flip the Lull mattress. However, you can rotate it to ensure even wearing. 

Our Verdict

It’s hard to beat the Lull for its affordability, but keep in mind that it’s best suited to average weight individuals and lightweight folks who prefer a firm bed. For users weighing 150-250 lbs, this bed has a medium-firm feel with an incredible balance of comfort and support. Our mattress review experts also feel that the gel-infusion technology on the comfort system helps a lot in managing heat build-up.
