What We’ll Cover in this Lull Mattress Review

As far as Mattress Dimensions go, they’re pretty standard for the most part. The different sizes of a mattress (Twin-California King) differ only about an inch or so from one another. What sets the Lull mattress apart its its thickness; most mattresses have a thickness of anywhere from 6-9 inches. The Lull is 10 inches thick, meaning there are more layers to cushion you as you sleep.

Usually, thickness relates to the number of layers, and the thickness of those layers, so the thicker a mattress is, the heavier it is because it contains more layers. This is a nice feature to look for, because this makes the mattress more accommodating and comfortable for a greater variety of sleepers. If you are a heavyweight sleeper and weight over 250 pounds, you may want to look for a thicker mattress (12 inches or more), so you can get the proper support you need.

The Lull mattress is slightly heavier than some other bed-in-a-box brands, but with more weight comes more soft layers. The box your mattress arrives in will vary in weight from about 45 to 100 pounds, so depending on the size of the bed you buy, it may be wise to find some help in carrying the mattress to whatever room you’re setting it up in.

Lull Warranty, Trial, Shipping & Unboxing

Lull gives you 100 days to figure out if you want to keep the mattress. If you don’t, they’ll pick it up for free and issue a full refund.  No need to shove it back into the box; they’ll retrieve it as is and donate it to an organization that needs beds.

The Lull comes with a 10-year limited warranty, meaning they’ll repair or replace (with a comparable model) the mattress if they see it has a manufacturing or material defect that has nothing to do with wear and tear or misuse of the mattress.

The Lull mattress ship free and will arrive 1-4 days after ordering. It will come compressed inside of a box. Setting it up is as simple as getting it out of the box and the plastic cover, then unrolling it on the bed foundation you’re using. The company says the mattress will expand the most within the first 2-5 hours out of the box and will be at its full thickness between 24-48 hours. They also say, for proper use, the “flatter the surface the better.” 

What Type of Mattress is the Lull? 

The Lull mattress is a gel memory foam mattress.

Does the Lull Sleep Cool or Hot? 

The density of memory foam has traditionally trapped heat. It has been nearly 40 years since the visco-elastic polyurethane foam was first produced for NASA so newer foams, like the ones in the Lull mattress, do a better job letting heat dissipate.

The Lull mattress top layer is infused with gel that gets rid of heat and helps sleepers doze at a comfortable temperature. This may not be enough for all people, so if you’re frequently suffering from night sweats, you may want to check out our top picks for best cooling mattresses for hot sleepers.

Lull Mattress Firmness & Feel

The Lull mattress is a medium-firm mattress, that skews slightly to the firmer side of medium. But foam does a great job contouring to the body so the Lull mattress relieves pressure and keeps the spine aligned while still being durable.

This will hold true for most average sleepers and even for heavier back sleepers.

Is the Lull Mattress Good For Couples? 

The Lull mattress has a lot in common with some of the best mattresses for couples. It runs on the firmer side of medium-firm and provides good edge support, so couples can use the entire surface of the bed without feeling like they’ll pitch off the side of it. And sitting on the edge of the mattress won’t depress the mattress so much that you slip off. By its very nature, memory foam does a great job minimizing motion transfer. You won’t be disturbed if your partner is moving around or getting out of bed on the Lull mattress, and neither will your partner.

Lull Mattress by Sleeping Positions 

Back Stomach Side Combination
✅Evenly distributes weight 

✅Good balance of contouring and support

✅Does not put any pressure on important points

❌Hips may sink for strict stomach sleepers 

✅Not too soft, but had enough give for hips and shoulders

❌Very lightweight sleepers may experience too much pressure 

✅Easy to move around for lightweight to average weight people

Back Sleepers: Back sleepers fare well on a lot of all-foam beds. The Lull is no exception. The Lull will evenly distribute the weight across the body and supports the lower back to keep the spine aligned. See all of our top picks for Best Mattresses for Back Sleepers.

Stomach Sleepers: Stomach sleepers will find this mattress does not put any pressure on pressure points but it also may cause some sinkage in the hips due to not enough support o keep the spine aligned.

See: Best Mattresses for Stomach Sleepers.

Side Sleepers: The Lull Mattress may suit side sleepers the best of all strict sleeping positions. The best mattresses for side sleepers are ones that cradle your pressure points and contour to your curves. Lucky for side sleepers, the Lull offers a perfect balance of softness and support, and provides excellent pressure relief, so you can wake feeling rested and refreshed instead of sore and tight.

Combination Sleepers: Leightweight to average sleepers will find this bed pretty easy to move around on. For heavier sleepers, you may find the Lull makes you feel “stuck” when you try to move from stomach to side or side to back.

Lull Mattress Design

Lull is made up of three layers of premium memory foam. The Lull mattress has a removable fabric cover made of polyester and rayon that is also breathable so it doesn’t heat up too much.

Top Layer: 1.5 inches of gel memory foam—foam for pressure relief and the gel for cooling.

Second Layer: 1.5 inches is a transition layer of foam—that provides a firmer foam layer between the softer top and the firmer base. It is meant to contour to the body’s curves.

Base Layer: 7-inch support layer.

Our Lull Mattress Final Review

Nerd Score: 4.6/5

If the idea of a memory foam mattress appeals to you, but pricey options do not, the Lull might be a great place to start.

It will accommodate most average size sleepers whether you sleep on your back, side or stomach because of the combination of contouring layers of foam and the support foam base underneath. You may be wary of trying a memory foam mattress for the first time as they do take some getting used to. However, with free shipping and returns and a 100-night trial period, what are you really risking? When you can get a memory foam mattress that costs under $1000, that’s a bit of a steal. If you’re intrigued, start with the Lull.

FAQs 

Will the Lull Mattress have off-gassing smells?

All-foam mattresses will have a smell when you unbox them. This is from the materials used to create the foams that are in the mattresses. The scent is not harmful and should be gone within a few days.

Do I need to flip my Lull Mattress?

Nope! You don’t have to worry about that with the Lull as it isn’t designed to be flipped. If you sleep with a partner and there is a significant difference in weight between the two of you, then Lull recommends rotating the mattress every 6-8 months.

What kind of foundation best supports the Lull?

While Lull recommends removing the mattress as soon as its delivered to your doorstep, you can keep it in its box for no more than 3 weeks. Keeping the mattress in its box longer than that can interfere with the bed’s ability to perform at its best.
