Lull Mattress Review

The Lull mattress is often described as “versatile” and “comfortable.” And when you can get a memory foam mattress that costs under $1000, that’s a bit of a steal. If you’re intrigued, you might want to start with the Lull.

Nerd Score: 4.6/5


Lull entered the bed-in-a-box game looking to throw a strike down the heart of the plate and build a mattress that accommodates the average sleeper regardless of their sleep position.

They delivered a memory foam mattress at an accessible price that does prove a good fit for the average person searching for a medium-firm mattress that will last. And when we say “accessible” we mean lower than most memory foam mattresses.

Customers describe it as “versatile” and “comfortable.” It gets high marks for the thing memory foam mattresses needs to do well—relieve pressure. You will get that comfort and contouring with the Lull mattress.

Also, just as an aside, go to the Lull website and take a minute to read up on the genesis of memory foam with NASA. It should interest anyone in the middle of researching mattresses and wondering how we got from innerspring to foam. Yes, memory foam started at NASA.

The Lull mattress is a gel memory foam mattress.


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.


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 keeping the spine aligned while still being durable.

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

Edge support

The Lull mattress is medium-firm and edging more towards firm than medium. That results in quite good edge support.

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.

Motion transfer

By its very nature, memory foam does a great job isolating motion. You won’t be disturbed if your partner is moving around or getting out of bed on the Lull mattress, neither will your partner.


Lull is made up of three layers of premium memory foam.

The top layer is 1.5 inches of gel memory foam—foam for pressure relief and the gel for cooling.

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

The bottom layer is a 7-inch support layer.

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.

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 definition of “defects” is fairly standard in the mattress industry:

  • Sags of greater than 1 inch that didn’t result from using the wrong foundation
  • Something wrong with the zipper that didn’t result from you yanking on it
  • Fabric tears or seams ripping due to poor construction

Delivery & Setup

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.”

Customer service

Lull was committed to easing customer complaints about the wackadoodle nature of buying a mattress in an actual store. So they put a lot of effort into customer service and it shows in online reviews.

The company is super accessible. Call, chat or TEXT Lull seven days per week during business hours or email anytime.
