Lull is a Santa Barbara-based mattress-in-a-box company founded in 2015 that sells a single foam-based mattress online. While many mattress-in-a-box companies sell a range of mattresses from soft to firm support, Lull has opted to stand behind a single mattress offering that has wide appeal with its medium firmness. 

The Lull mattress is a unique three-layer design that mixes traditional foam with a layer of memory foam for comfort. It is 10-inches thick and the three layers include:

  • 7” polyurethane foam foundation
  • 1.5” foam blend transition layer
  • 1.5” gel-infused memory foam top layer

This is a uniquely simple design within the memory foam bed industry, but Lull stands behind the mattress and says its design offers durability, strength, and spinal support to sleepers. The foundation of the lull mattress is the support layer that absorbs movement and prevents bouncing during sleep. It also helps prevent sagging during the life of the mattress. The transitional layer prevents the mattress from having that sinking sensation that some softer memory foam mattresses can produce. And finally, the cooling top memory foam layer provides the soft, cradling feeling that people find attractive about memory foam beds. Lull also says that the gel-infused foam on this top layer helps you to sleep cooler and more comfortably. 

Lull’s mattress is CertiPUR-US®-Certified which is almost the industry standard now. This means that its mattress is made with no harmful chemicals, no formaldehyde, no ozone depleters, will produce minimal off-gassing, and more. It is also a Sustainable Furnishing Council® Member as well as a Mattress Recycling Council® Member. Its mattress does not have GREENGUARD Gold Certification which many more expensive mattresses have to verify their commitment to environmentally and human friendly practices.

In addition to its mattress, Lull sells the full array of accompanying products such as bedding and bed frames. Lull also sells a convenient and well-priced bedding bundle that includes two pillows, a sheet set, comforter, and duvet cover starting at $505. This is a great price. However, Lull’s top competitor actually includes some of these items with a mattress purchase. 

Top Ranked Companies


The Good

  • Price
  • Overwhelmingly Positive Customer Reviews
  • Option to Purchase from Amazon
  • Benefits of Memory Foam with Support From Foam
  • Warranty


Lull’s mattress is well-priced and is competitive with other mattress-in-a-box competitors. Its mattress starts at $649 for a twin size mattress. This is a great price for a well-reviewed mattress with the Lull warranty in comparison to some higher-priced mattress-in-a-box mattresses that can start in the low $800 range. 

In addition to its already affordable prices, Lull typically has discounts or sales running on its website. When this review was written, the company was running a promo that gave customers $150 off any mattress size. 

Overwhelmingly Positive Customer Reviews

Lull’s mattress has thousands of positive online reviews across several review platforms. Customers seem to really enjoy the mattress. Interestingly even customers who seem to express that they didn’t love the mattress initially end up including in their review that after a few weeks of adjustment they really enjoy the Lull mattress.

We are also impressed by Lull’s review guarantee. Lull promises they do not hide negative reviews. It even stands by this promise with a guarantee to provide customers with a full refund if it doesn’t post their review.

Option to Purchase from Amazon

Several mattress-in-a-box companies now sell their mattresses on Amazon. If you prefer the convenience of purchasing from Amazon, you are able to buy Lull’s mattress in Queen size only. We recommend that you compare the price on Amazon with Lull’s website to make sure you are getting the best deal since you will receive free shipping either way.

Benefits of Memory Foam with Support From Foam

Because Lull sells one mattress, the company has crafted it to appeal to as many sleepers as possible. It falls in the middle in terms of support. Many reviewers like that the mattress offers good support from the foam foundation layer as well as the body-hugging features of memory foam from the top layer. 


Lull offers customers a good warranty, similar to many competitors. Customers can try out its mattress for 100 nights risk free. If you don’t like your mattress, Lull will pick it up for free and give you a full refund.

The Bad

  • Mattress May Not Be a Universal fit
  • Mattress Cover Limitations
  • Only One Mattress Option
  • New Mattress Smell

Mattress May Not Be a Universal Fit

The Lull mattress is 10 inches thick. This is on the thinner end of most mattress-in-a-box offerings. Most start their mattress thickness at 12 inches. Because of this and other factors, the Lull mattress may not be a good fit for all people including larger sleepers. 

Lull states on its website that it was designed to comfortably support two people weighing up to 250 lbs each. 

Mattress Cover Limitations

Mattress covers are important for maintaining the warranty on your mattress and comfort — and in the case of Lull’s mattress, maintaining a comfortable sleeping temperature. 

However, Lull’s mattress cover, unlike other mattress-in-a-box sellers, is not removable and therefore not machine washable. Reviewers state that while the cover is technically removable, it is almost impossible to get back onto the mattress. Lull does not recommend removing the mattress cover and that you do not touch or place anything on the fire retardant sock surrounding the mattress. 

It does sell a good mattress protector to help customers prevent the need to remove and wash the cover. 

Only One Mattress Option

Because Lull only offers one mattress it will likely not be a good fit for all sleepers. Other companies sell a range of mattresses that vary in support and other features. Lull says that tests from an independent consumer product lab rate its mattresses’ firmness at six, based on a scale of one (very soft) to ten (extremely firm). 

New Mattress Smell

While Lull’s mattress is CertiPUR-US®-Certified many people noted in their reviews it has a strong chemical, new mattress smell when first opened. Lull says that any smells a customer notices are normal and its mattress does not contain any harmful chemicals.


The Bottom Line

If you are looking for a well-priced, convenient mattress that is medium-firm then you will likely be very satisfied with the Lull mattress. Its mattress has been reviewed by thousands of customers and has an overwhelmingly positive rating. The mattress's construction should appeal to many, and the company also offers customers a nice assortment of bedding and bed frames.

You should note that the mattress is only rated to support two sleepers up to 250 lbs each. If you are larger, this may not be the mattress for you. If you prefer a softer mattress or that sinking-in feeling that some memory foam mattresses offer, you will also not likely enjoy the Lull mattress.

Because of its excellent 100-night risk free trial with free shipping and free returns, Lull is a great option to try. We also like that it offers customers the option to finance their purchase if needed.

It was time to get my mother a new mattress. She's had the same one for 20 years. We found the Lull bed in a box that shipped right to her door. The mattress relieved her back pressure. She's got dogs and they get on the bed. There are layers to help distribute the motion to keep the bed for shaking when the animals climb on it. The memory foam keeps it's shape over time.
