Lull Mattress Video Overview

For those of you who would rather watch than read, here is a quick summary video detailing what we like most about the Lull mattress.

There’s only so much detail we can fit into one video though. Keep reading to learn more about the Lull bed-in-a-box.

Lull Company Policies—Shipping, Warranty, etc.

Lull, like most online mattresses, ships completely free within the United States. They ship with FedEx Ground, and according to their website, usually take anywhere from one to four business days for delivery.

Your Lull mattress will show up to your home in a box that’s a little bit larger than a mini fridge, which Lull likes to boast reduces package volume up to 70%. Once your mattress is unpackaged, arrange it on your bed frame and allow it to inflate to its full shape, and off-gas a bit. Since the bed has been wrapped in plastic for a few days it could have a chemical smell to it. This usually goes away within a week. Here’s what that unboxing process looks like.

Again, like most bed-in-a-box mattresses, Lull always offers completely free returns if you for some reason are unhappy with your purchase. All they ask is that you give your mattress at least two weeks before requesting a return and refund because it takes some time for your body to adjust to a new sleep surface.

If you do happen to return your mattress, Lull will send a third party charity to come to your house and pick it up for you, so no work is required on your part.

Lull also offers a 10-year warranty with their mattress, which is, again, what most other online brands offer. Basically, Lull offers the industry standard regarding their policies—which we should acknowledge is a pretty good standard.

Lull Bed Price and Coupon Code

Lull offers their mattress at a fairly affordable price, which they claim is because they cut out the retailer middleman, as is the case with a lot online bed-in-a-box brands. In our opinion, this is actually a really nice mattress considering the price, especially if you don’t want memory foam or neutral-foam, but something in between. Here’s a full pricing break down:

SizePrice (MSRP)
Twin XL$650
King / Cal King$1,000

While Lull is already pretty affordable, they also typically offer promo codes for around $50-100 off their bed during holidays, good moods, etc., and also offer financing options. You can check for current offers and deals.

What Is Lull Bed Made Of?

Lull has some somewhat of an interesting feel. It is constructed with both polyurethane foam (poly foam) and memory foam, and feels like a super comfortable balance between the two (i.e. there’s no overwhelming memory foam feel).

Let’s break it down. So first, Lull has a 7” foam base layer for support. Next is a 1.5” transitional layer made up of a proprietary blend of foams, which for this review we’re simply calling neutral-foam, but in reality is just poly foam. This is what limits the stuck-in-the-mud feeling you would otherwise get with the 1.5” memory foam top layer. Altogether, this creates a 10” thick, 3-layer, all-foam bed.

Construction of the Lull mattress

While this mattress will be easy to move around on, you still get a bit of that cuddly, sink-in feeling that memory foam provides.

Lull states on their website that all of the foams that they use are CertiPUR-US Certified, which means that the materials have met rigorous standards of minimal off-gassing. Lull also states that they don’t use harmful chemicals, such as formaldehyde, ozone depleters, heavy metals, and certain flame retardants. All of their foams meet a standard of fewer than 0.5 parts per million volatile organic compounds (VOC).

Lull is also a member of the Sustainable Furnishings Council, which means they take steps to minimize their carbon emissions, waste stream pollutants, and non-recyclable content. Basically, Lull is a champion of the environment.

Cover, Cleaning, and Care

Lull wraps up their all-foam mattress with a soft cover made of polyester and rayon. While it is removable, we don’t recommend actually removing it because it’s a pain to put back on. It’s not machine washable either, which tends to be the case with most online beds. But fret not, if you spill anything on this mattress while you’re brunching in bed, just spot clean the area with some mild detergent and warm water.

Lull also offers a mattress protector on their site, called the Lull Protector. It’s supposed to be 100% waterproof and spill resistant. It’s also machine washable, which makes it hypoallergenic because you can wash away any dust, skin cells, or dust mites. This is a nice addition if you’re a clean freak or have sensitive allergies. If you want a cover, be aware that any mattress protector from Amazon and other retailers should work. You don’t have to get the one from Lull.

Feel, Firmness, and Responsiveness of Lull Bed

Lull has a unique feel that’s a blend between both memory foam and neutral-foam, with an overall medium firmness level. Since they only offer one bed in their line (as of the date of this post), this is the only firmness option available, but it should be accommodating for most sleeper types. You can get more details on that later in this post.

In our opinion, the Lull feels like you’re laying on a soft cloud, but then the material begins to contour to your body and you sink in a bit, like the cloud is hugging your body back. We find it somewhat unique, and definitely comfortable.

Because of the memory foam, this bed isn’t immediately responsive. You’ll see your hand print for a second or two after pressing into it; this is why the bed feels like it’s kind of hugging you.

Good pressure relief, but slower responsiveness

Even though the Lull is slower to respond, we didn’t find it made us feel “stuck in the mud.” This is because of the neutral-foam layer right beneath the memory foam. Because it’s fairly easy to move around on this bed, this is a good option for combo sleepers who like to switch positions during the night, but still want a memory foam bed. The less resistance you face while moving around on the bed, theoretically, the more restful sleep you’ll have.

Is The Lull Good for Back and Stomach Sleepers?

The Lull should be good for most sleeper types, including back and stomach sleepers. Keep in mind that a lot of this depends on body type, though. Back and stomach sleepers need a firmer surface in order to keep their hips and shoulders in proper alignment. Beds that are too soft will let them sink into the bed excessively, which can lead to pain or discomfort in the morning.

Good for a lot of back and stomach sleepers

The more petite you are, the less pressure you’re putting on the mattress, and the more you’ll lay on top of the bed instead of down in it. Therefore, the bed will be firmer for petite body types, and better for sleeping on your stomach or back.

We think medium or average body types will also be supported on this bed no matter what sleeping position they prefer.

Is The Lull Good for Side and Combo Sleepers?

Yes. Side sleepers will typically want a softer mattress, which will provide more pressure relief, particularly for their hips and shoulders. We wouldn’t consider Lull to be a plush mattress, but it’s definitely soft and pressure relieving enough for strict side sleepers. In fact, if you twisted our arm, we’d say Lull is better suited for side sleeping than anything else.

Combo sleepers tend to switch sleeping positions throughout the night. As we’ve mentioned, petite to average sized individuals should be fine with switching positions, especially because the memory foam on this bed doesn’t really have any of that stuck-in-the-mud feeling, which means they’ll face less resistance while moving around. Heavier combo sleepers should look for a firmer bed or something that incorporates coils for durability.

Is Lull Good for Heavier People?

No—this is an all-foam, 10” thick bed, and while we think that there’s a lot to like about it, it’s just not going to be supportive enough for larger people long term. It’s just not designed for that. if you’re at, or over, 250 lb you should probably look into the beds on our list of the best mattress for heavy and obese sleepers.

Does Lull Sleep Hot?

While memory foam is usually known for trapping heat because of how the material contours around your body, Lull is pretty much temperature neutral. That said, if you sleep excessively hot at night, you may want to look into a bed with some active cooling features, like the Brooklyn Aurora or the other selections on our Best Cooling Mattress for Hot Sleepers list.

For Couples: Edge Support and Motion Isolation

Edge support is important for couples who like to fight over the middle of the bed, or sleep on a smaller bed in relation to their size. Lull doesn’t have the best edge support, so if you’re a couple interested in this bed, go a size up or cuddle in the middle.

Great for motion isolation

As for motion isolation, Lull does a good job here, so you probably won’t feel your partner moving around or getting up during the night, which is important if you’re trying to get restful sleep. Even sensitive sleepers will likely be able to sleep soundly with Lull.


We like Lull, but it’s not for everyone. It has a unique feel that sits somewhere in between a standard poly foam and memory foam. It also is designed for petite and average sized individuals, not heavy people. And when it comes to temperature regulation, there’s nothing really special about Lull. The bottom line is that you get this bed if you’re looking for a slightly softer foam mattress, but you aren’t in love with a traditional memory foam feel.

How did the Slumber Yard get the Lull mattress?

We were sent this bed from Lull, however, we did not accept any money to say positive or negative things about it. We review products independently.

What kind of bred frame should I use with my Lull bed?

On their website, Lull states you can use your Lull bed on any slatted bed frame, box spring, or even the floor. They suggest you use a surface that allows for air ventilation in order to prevent any mold. Lull also sells their own bed frames in metal and wood, so you can check those out on their website.

What does a Lull mattress smell like?

Your Lull mattress might have that new mattress smell for a couple of days, but it usually fully disappears after that time period. On their website, Lull states that any smells that you may notice with your new Lull bed are completely normal when purchasing products that contain new foam, and that none of their mattresses contain harmful chemicals. Just make sure to give your bed time to air out a bit before sleeping on it.

What kind of sheets should I get for my Lull mattress?

Standard sheets according to your bed size should be fine. On their website, Lull recommends you get sheets with elastic sewn into the edge, all the way around, for the best fit.
