Compare What’s Inside

Lull provides a premium memory foam mattress at an affordable price. We've compiled a side-by-side comparison of Lull's top competitor, Casper, to see which mattress is the right choice for you. Casper is the name brand you think of when you hear "bed-in-a-box."

Lull & Casper at a glance

With an advanced three-layer construction, the Lull mattress is comfortable and supportive. It combines a gel-infused top layer for cooling comfort and proprietary foam underneath for therapeutic support. The Lull mattress is a great value—costing a fraction of what you'd expect to pay for a premium memory foam mattress at a traditional retail store. While Lull remains one of the most popular beds nationwide, is it really worth the hype?

Let's take a look at Lull and their closest competitor to see which mattress brand reigns supreme.

Competitor #1: Lull

Lull Mattress

Designed by experts with 30 years experience, the Lull mattress features three layers of Advanced Sleep Technology. This exclusive material is up to 7x more durable than conventional foam. It stays cool with its breathable gel top layer while simultaneously aligning your spine. The Lull mattress is CertiPUR-US® Certified, so all materials are non-toxic and safe for the environment. It's also great at absorbing motion. The foam layers ensure that motion isn't transferred over the entire bed's surface. If you sleep with a very active sleep partner, Lull guarantees their movements won't disturb your sleep.

  • Starts at $499 for a Twin and goes up to $999 for a California King

Competitor #2: Casper

Casper is the brand you think of when someone says "mattress in a box." They are eco-friendly and offer the option to try their beds in one of their showrooms in most metropolitan areas. For this comparison we're focusing on the Original Casper. Over 70% of people who have slept on a Casper say it improved their sleep. They have 3 models:

Original Casper

A great all-around mattress, offering both support and cooling. The mattress helps with spinal alignment with 3 different support zones. The softer foam around the neck and upper back provide relief, while firm foam around the waist and hips align the spine. Comes in hybrid or an all-foam option.

  • Starts at $595 for a Twin and goes up to $1,295 for a California King

Wave Hybrid

The Wave Hybrid offers the maximum support for pressure points using gel pods to keep your spine in line. The Wave keeps all the same cooling advances as the Original just with more support. 90% of sleepers reported less back pain using the Wave.

  • Starts at $1,495 for a twin and goes up to $2,995 for a California King.

Nova Hybrid

Casper's newest mattress, the Nova offers plush comfort without sacrificing support. 7 different support zones help keep your spine aligned.

  • Starts at $1,095 for a Twin and goes up to $2,295 for a California King.

Side-By-Side Comparison

Lull and Casper both offer supportive memory foam mattresses, but are made for different types of people.  Lull focuses on offering a balanced sleep for every sleeper type, while Casper makes mattresses that offer increased support for your back. They're priced about the same and offer the same length trial and warranty. So which should you choose?

Lull offers a mattress that is great for people that aren't specific to one issue. If you're looking for a mattress at a good price Lull is a good buy. If you prefer a firmer mattress, Lull is definitely the better choice. Despite its all-foam design, the Lull mattress is firmer than average—ranking around 7-8/10 on the firmness scale. The high-resilience memory foam prevents you from sinking too far into the mattress, making it a great choice for back and stomach sleepers. The firm feel ensures your spine stays properly aligned all night long.

Casper offers memory foam mattresses and hybrids with more support than the average bed-in-a-box. Casper is perfect for those sleepers who need a mattress with targeted pressure relief and firmer support for proper spinal alignment. If you need a bed with a medium-feel, then Casper is the perfect choice for you.

How To Choose The Right Mattress

First off, if your current mattress is 7-10 years old and you're experiencing more body aches and pains, it's time to buy a new mattress. Getting a good night's sleep is essential in maintaining a healthy body and mind. Choosing the right mattress doesn't have to be a hassle, follow these guidelines to find the right one for you!

  • Choose a mattress based on your individual needs. If you're looking for plushier support that adapts to your body's shape, a memory foam mattress is the best choice. If you want a more firm, traditional, feel an innerspring mattress is what you want. For the best of both worlds, get a hybrid mattress.
  • Get proper lumbar support. The majority of your body weight is positioned in what is called the "center third" of the mattress. Find a mattress that has excellent lumbar support as it prevents and alleviates pain in the back and hips. If you're looking for extra support, Saatva's unique lumbar zone technology might be the best fit.
  • Find a mattress with a long in-home trial. You want to be able to test your mattress over an extended period of time to really make sure this is the right one for you. Look for a company that offers a risk-free in-home sleep trial. Nectar offers a 365-day trial. IDLE Sleep offers a full 18-month trial (the longest in the industry).
