According to the Centers for Disease Control and Prevention, 1 in 3 adults aren’t getting enough sleep. And while acquiring good nighttime habits is one way to help improve the quality of sleep, investing in a new mattress may also help significantly.

If you’re in the market for a new mattress, you may have come across two popular bed-in-a-box mattress manufacturers: Casper and Lull.

Casper and Lull are both known for manufacturing high quality mattresses that come with solid warranties. Both companies are based in the United States and use American workers to produce a portion of their bedding products.

In this article, we’ll do a deep dive into Casper and Lull, as well as compare the two brands’ flagship mattresses.


Casper Sleep, Inc., which was founded in 2014, is one of the original manufacturers of compressed bed-in-a-box mattresses.

Casper mattresses can be purchased online and in select retail stores. They also go on sale several times a year.

There are three different mattresses in the Casper line, designed to accommodate a variety of sleep positions, preferences, and budgets. Most can be purchased as either a foam or hybrid innerspring mattress, and support levels range from soft plush to medium firm.


Lull was founded in 2015. They manufacture sleep products, including one bed-in-a-box mattress, pillows, and sheets.

Currently, you can only buy Lull mattresses online through the Lull website and Amazon. This sales model ties into Lull’s ideology of reducing middlemen and eliminating retail store markups. They also offer discounts often.

Lull doesn’t like to be pinned down about the firmness level of their mattress. When asked, customer service representatives are likely to tell you that firmness is subjective and based on the sleeping experience, body type, and needs of each sleeper. According to some user reviews, the Lull mattress gives soft-to-medium soft support.

Lull mattresses are manufactured in the United States and Asia with local and imported materials.

  • Customization. Lull only offers one mattress and one firmness level. Casper offers three different mattresses, and their Original mattress is available as a foam or hybrid.
  • Softness. Reviewers say the Lull mattress is entirely made of foam and on the soft side, whereas the Casper Original Hybrid has innerspring support and firmer edges.
  • Availability. The Casper Original Mattress is available on the Casper website and in stores so you can try it yourself. The Lull mattress is only available on the Lull website and Amazon.

Casper Original Mattress

  • Height: 11 inches
  • Size options: Twin, twin XL, full, queen, king, California king
  • Firmness rating: Medium to medium firm
  • Warranty: 100-night, risk-free trial, a 10-year limited warranty

The Casper Original was first offered exclusively as an all foam mattress. It’s also available as a hybrid with innersprings, if you’re seeking more support.

The Casper Original is constructed with three support zones, which make the mattress soft and cushy around the shoulders (so side sleepers won’t wake up with a numb arm) and firmer underneath the spine, waist, lower back, and hips.

A study from 2015 suggests that medium-firm mattresses are the best choice for spinal alignment and comfortable sleeping. However, it’s important to note that memory foam mattresses are, as a general rule, less firm than innerspring mattresses.

Memory foam is also notoriously warm, but the Casper Original’s top foam layer is perforated, which is intended to disperse heat and increase airflow. Reviewers generally speak positively of its cooling abilities.

Who is it for?

If you’re seeking a soft to medium mattress, the Casper Original’s all-foam version provides a soft, yet supportive surface.

If you’re an edge sleeper or prefer more bounce, you may be better off with the hybrid, since it has a solid, firm border and a spring base that adds lift.

Both versions of the Casper Original get high marks from couples for motion isolation.

The Lull Mattress

  • Height: 10 inches
  • Size options: Twin, twin XL, full, queen, king, California king
  • Firmness rating: Soft to medium
  • Warranty: 100-night, risk-free trial, a 10-year limited warranty

The Lull Mattress (Lull’s only mattress) is made from three layers of foam. Lull customer service representatives say it has a one-size-fits-all firmness level, although reviews suggest that this mattress is on the soft side.

The top layer is made from gel-infused memory foam, which is intended to dissipate heat and promote maximum airflow. An inner transition layer is made from a supportive resilience foam that’s designed to support and cushion the body without sinking.

The base layer is made from polyurethane foam for durability, support, and to prevent sagging. This mattress doesn’t require a box spring.

Who is it for?

Users say the Lull mattress provides a hugging feeling and is best for side sleepers who like a softer mattress. Some stomach sleepers say this mattress is too soft to provide ample support around the hips.

A handful of reviews also mention motion isolation and say the Lull lets couples change positions easily without disturbing their sleep partner.

Both brands are bed-in-a-box mattresses. They’re delivered hands-free in compressed packaging. This means your mattress will need between 24 and 48 hours to expand to its full size.

As with most compressed mattresses, you might experience a funky (but harmless) off-gassing scent as your mattress expands, so it’s best to open a few windows or take the mattress outside. However, reviewers have reported little-to-no new mattress smell upon arrival with both Lull and Casper mattresses.

Casper offers a setup service for $149, provided you also buy one of their select bedframes or a California king-sized mattress. They will also cart away your old mattress if you live in one of their in-home delivery and setup market areas.

Lull doesn’t offer a setup service.


The Casper Original Mattress comes with a 100-night, risk-free sleep trial and a 10-year limited warranty.

You can make a free return or request an exchange during the 100-night sleep trial. If you wish to return your mattress, Casper will arrange a free pickup through a local charity that accepts furniture donations and refund you the full cost.

In the event of an exchange, you won’t be entitled to the 100-night, risk-free trial or a refund, should you wish to return the second mattress.


Lull offers a full money-back guarantee if you wish to return your mattress within the first 100 days. They also provide free pickup and removal.

Note that these terms only apply to mattresses purchased directly from Lull and not from a third party retailer, including Amazon. If you’ve purchased from Amazon, you’ll have to go through their return process.

Casper and Lull mattresses have CertiPUR-US certified foams, made without ozone-depleting materials or toxins — including flame retardants, lead, mercury, formaldehyde, phthalates, and heavy metals — as regulated by the Consumer Product Safety Commission.

Both Lull and Casper mattresses also meet federal government standards for flammability deterrents, as governed by 16 CRF 1633 and 1632.

Casper Sleep, Inc. is endorsed by the American Chiropractic Association for producing high quality products.


The Casper Sleep company has an A+ accredited business rating from the Better Business Bureau. They have a 4.3 (excellent) rating from Trustpilot.

In 2020, a class action lawsuit was filed against Casper Sleep, Inc. by some of their investors.


Lull has an A+ accredited business rating from the Better Business Bureau and a 3.6 (average) from Trustpilot. However, Lull’s Trustpilot rating is misleading, since the only customer review on the site gave Lull very high marks.

Customers of both Casper and Lull mattresses are typically satisfied with their products and the level of customer service they received.

The Casper Original gets fairly consistent high marks for reducing back pain and having no motion transfer.

The Lull gets consistently high marks for eliminating or reducing all-over aches and having limited to no motion transfer.

Both mattresses are reported to be hard for some people, particularly older individuals, to get onto the bed.

Casper Sleep, Inc. and Lull are two American companies that produce foam-based bed-in-a-box mattresses. Their mattresses are compressed and shipped hands-free directly to your door.

The Lull Mattress is all foam, while the Casper Original is available either as an all foam or hybrid mattress.

Key differences between the two brands include more customization options and accessibility with Casper than Lull.

The Casper gets high marks from back, side, stomach, and combination sleepers, especially in its Hybrid version. The Lull is favored by back, side, and combination sleepers, and may be better for folks who like a soft mattress.
