Lull Mattress Review – A Firm, Comfortable Foam Mattress

Lull mattress

Lull is another mattress-in-a-box brand that aims to appeal to all types of sleepers. They want you to be just as comfortable in every position you try.

Sven Klein, founder and CEO, entered the mattress business because he didn't like the mattress business. It all started when he and his wife were shopping for a new mattress. It seemed like the salesmen were more concerned about the sales than the satisfaction of the customer. He was tired of the pushy atmosphere, and the stress of keeping track of the varying prices for each store. From that frustrating situation came an "aha moment," and Lull was born. 

Lull is unique in that their top layer of memory foam breaks the convention of traditionally warm memory foam mattresses by adding cooling gel.

But does Lull actually live up to its promise of quality? Let’s take a closer look.

Firmness and Support

Very Soft

Very Firm

Lull: 8/10

The Lull mattress is firmer than a lot of the other foam-only mattresses we’ve reviewed. It’s not so firm that it starts to create pressure points, but firm enough to offer support for most sleeping styles.

If you’re a combination sleeper and primarily sleep on your back and stomach, this firmness level is probably the one you want. It sinks where it’s supposed to and supports your back, so you wake pain-free.

Although some side sleepers will be comfortable on this mattress, back and stomach sleepers will find it much more appealing. Side sleepers generally like a softer mattress, and the Lull pushes the boundaries of what a side sleeper might endure. It’s comfortable enough for brief stints on our side, but those who always sleep on their side will probably want a softer option in a mattress.

As far as edge support goes, Lull is far above average. When sitting or lying on the edge, you never get the feeling like you’re falling towards the middle.

Motion Isolation



Lull: 9/10

The motion transfer in the Lull mattress is virtually non-existent. The top layer of the mattress is made of cooling memory foam, which means a partner’s motion shouldn’t disturb even the lightest of sleepers. There aren’t too many mattresses that can handle the wine glass test, but this is certainly one of them.

The bounce of the mattress is towards the middle of the pack. Some memory foam mattresses make you feel stuck in one position, but the Lull solves that problem. It’s not the most responsive mattress we’ve seen, but this shouldn’t be a problem for most shoppers.

The firmness level of the Lull compensates for the lack of responsiveness. You don’t sink into the mattress, so the Lull gets a little more leeway when it comes to bounce.

Off-Gassing and Smell

Every new mattress comes with a factory smell, but some people are more sensitive than others. If you’re extremely sensitive to the smell of a new mattress, this might not be the best selection for you.

The off-gassing of the Lull won’t be a dealbreaker for most people, but I found that the “new mattress” smell lingers longer than some of the other mattresses we’ve reviewed. It goes away after a couple of days, but those with sensitive noses might wake with a headache the next day.

If weather permits, leave the windows open in your bedroom to help the smell go away. It should disappear in the matter of a few days, though, and there’s no overwhelming scent after that.

Construction and Material

The top layer of the Lull mattress is comprised of 1.5 inches of gel-infused memory foam. Lull designed the layer this way to provide both comfort and cooling. A lot of other memory foam mattresses cause sleepers to wake up in a pool of sweat. The gel infusion neutralizes the heat retention of memory foam, allowing for a cooler night’s sleep than other memory foam mattresses.

Beneath the memory foam is 1.5 inches of poly foam. It’s a transitional piece of foam between the firm bottom and soft top. The poly foam distributes your weight according to your sleep position for optimal spinal alignment.

At the bottom of the mattress is seven inches of dense support foam. This layer is the foundation of the bed, and where most of the firmness comes from. The support foam, while firm, helps dampen the motion transfer across the bed. When combined with the top layer of memory foam, the result is virtually no motion transfer in a Lull mattress.

Does it Sleep Hot or Cool?


Since the top layer of the Lull is memory foam, you might think that it sleeps hotter than some of the other mattresses we’ve reviewed. Surprisingly, it falls somewhere in the middle, and is about the same temperature as a Casper or a Leesa mattress.

If heat isn’t a problem for you when you sleep, this bed will be perfectly fine. If you’re struggling to find a bed that keeps you cool, however, you might want to look elsewhere. The Lull is comfortable and cooler than a lot of other mattresses that use memory foam as a top layer. Lull doesn’t prioritize cooling like other brands, though, so it won’t provide relief for the hottest sleepers.

Unique Features

  • The motion transfer is the primary characteristic that sets this bed apart from the competition. Other than that, there isn’t too much innovation in this bed. Lull sticks with what works and provides a firm, supportive mattress that will fit most sleeping styles.The only unmentioned place where Lull shines is in the cover that comes with the bed.
  • The Cover: The cover is one of the bright spots in the Lull mattress. Most people don’t put the cover of a mattress as a top priority, but it’s an important element of any mattress. Ideally, you want a cover that’s soft, elastic, and durable.The cover on this mattress checks all of these boxes without sacrificing durability. Lull makes their covers out of polypropylene and polyester, and they provide a cool, breathable cover that can handle some rough pulls.

Public Perception

User reviews for the Lull mattress are generally positive. Some outliers complain about their experiences, but this is usual for a bed. Everyone sleeps differently, so there’s no guarantee that a particular mattress will work for you.

The biggest complaints came in the firmness of the mattress. These usually came from side sleepers who couldn’t find a comfortable spot.

Other than a few complaints, sleepers seemed to like their experience with the Lull mattress. The reviews were about as positive as most of the other mattress-in-a-box options we’ve seen.

Check out a short review and unboxing video here:

Here are the thoughts of someone who’s slept on the bed for a year:

The Purchasing Process

From ordering to delivery to setup: Lull makes the buying process easy for their customers. There aren’t many options to choose from, but this is a good thing when it comes to mattresses. Other brands can overwhelm customers with a variety of different options. Lull keeps it simple.

Once you’ve decided that the Lull bed is the right choice for you, all you have to do is settle on a size and plug in your information. The mattress is speedy in getting to you and should be at your door in one to four business days.

Unboxing the mattress is similar to most mattress-in-a-box processes. The box is around the same weight as comparable mattresses, and most people can unbox it by themselves without the help of an assistant.

Most of the expanding will take place in the first two to five hours after opening. You can sleep on the mattress after that, but it won’t fully expand for another 24 to 48 hours.

Customer Service

Customer service is one of the strong suits of Lull -- and it has to be. Mattresses that do all of their business online need to have responsive customer service, or else they’ll lose a large percentage of the market.

You can send an email at any time, or call, text, or chat with a representative from 6 am to 6 pm PT every day. They’re quick to respond to emails, and keep you updated throughout the process of getting your problem resolved.

How Much Does It Cost

As of this writing, Lull is giving all of their customers $50 off of a new mattress. They also offer regular promotional codes, and you may have seen them advertised with some personalities you follow. Like a lot of online mattress companies, they frequently use holidays as a way to discount mattresses. If you can wait until the next national holiday, it may save you a few dollars.

The price breakdown is as follows:

  • Twin: $500
  • Twin XL: $550
  • Full: $700
  • Queen: $800
  • King: $900
  • Cal King: $900

Price varies depending on which company you're looking at. Check out the Top 10 Best Mattresses to see how Lull's price compares to the best on the market.

How It Compares

The Lull is firmer than a Casper mattress but softer than mattresses like Purple. It’s not the coolest mattress on the market, but it won’t overheat you if you don’t naturally run hot while you sleep.

The price is on the lower end of the spectrum, though it’s not the cheapest option either. When comparing it to other mattress-in-a-box option, it falls somewhere near the middle depending on your preferences. If you’re looking for a bed that’s firm, comfortable, and keeps motion transfer to a minimum, it should be closer to the top of your list.

Is Lull Right For You?

If you’ve ever owned a Leesa mattress but wanted something a bit firmer, the Lull will be what you want. On the other hand, if you like most of the attributes of the Lull bed but want something that’s a bit softer, take a look at our Leesa mattress review and see if it fits your needs.

If you’re constantly hot when you sleep, take a look at our Purple mattress review. Purple prioritizes keeping you cool, and Lull doesn’t focus on it as much. Most people won’t overheat on a Lull, but it won’t keep the hottest sleepers comfortable during the night.

The Lull is perfect for someone who wants a foam mattress that stays firm and limits motion transfer. These are the places where the Lull shines the brightest. It’s not the best as far as bounce and responsiveness are concerned, though. For these characteristics, I suggest taking a look at our Eve mattress review.
