Casper vs. Lull Mattress Comparison

We’ve worked hard to show you which mattresses are the best fit for you. Check out our full mattress guides listed below!

Sizing Options

There are many factors to take into account when selecting the size of your new mattress. Most importantly, who will be sleeping on the mattress? If shopping for yourself, do you share a bed with a partner? If so, what is their preferred sleeping position, and how is it similar or different to your own? Do your pets often sleep in the bed with you?

What about body type? A very tall individual, a light sleeper who moves around a lot, and a couple who are both heavyset will all need larger mattresses, while a California king may be too large for a solo sleeper or a child. Likewise, an overly tall model may not be the best option for children or individuals with mobility issues.

Casper and Lull both offer a full range of sizes for all models, including twin XL and California king options. However, Casper’s product range includes hybrid and all-foam models, while Lull’s sole option is an all-foam product. Like most mattresses in their category, Casper’s hybrid models are somewhat heavier than the company’s flagship model, the foam-based Element, or the Lull. This is due to the hybrids’ coil-based support cores. The Wave Hybrid also features zoned lumbar support in the form of gel pads, which provide additional weight.

At 13 inches tall, the Casper Wave Hybrid is considerably larger overall than the other models in our comparison. Customers seeking a mattress for a child’s bed may instead prefer the shorter, lighter Lull or the Casper Element. Likewise, individuals who struggle to get in and out of bed might benefit from the Lull, which is only 10 inches tall but provides targeted support at pressure points.

Construction and Materials Comparison

The construction of a mattress affects its firmness level, durability, and overall feel. Certain body types and sleep styles tend to benefit more from hybrids, while others do best with all-foam mattresses. However, product differences go beyond basic structure, and so do their benefits and drawbacks. For example, hybrid models generally offer better temperature neutrality than all-foam mattresses, but very hot sleepers might still do best with a hybrid that includes cooling gel in its comfort layer.

Additionally, some mattress types are more durable than others, and material quality can strongly impact longevity. Memory foam, for example, is notorious for sagging with time. Before making a purchase, it may help to research the materials used in your mattress. From where are they sourced? Do they hold any environmental or industry certifications? What do customer reviews have to say about that model’s durability?

Casper

The Casper Original is an all-foam model that features three targeted zones encouraging proper spinal alignment. Beneath a knit polyester-blend cover, a layer of perforated AirScape foam targets pressure points. Softer foam cradles the shoulders and upper lumbar region, while a 2-inch transitional layer of zoned memory foam supports and reduces pressure on the hips and lower back. A 7-inch support core made of high density polyfoam serves a durable base that prevents sagging. The bed’s cover contains material from up to 57 recycled plastic bottles.

While the Casper Hybrid is nearly identical in construction to the Original, its support core is made from a 7-inch layer of pocketed coils reinforced by a polyfoam encasement, which provide additional air flow, bounce, and stronger edge support.

Another foam mattress, the Element features a cover made from a recycled polyester blend and a simple, two-layer construction. The model includes 3 inches of AirScape open cell polyfoam and a 6.5-inch high density polyfoam support base.

Although Casper’s Wave Hybrid and Nova Hybrid are similar to one another, they differ in construction and are designed for different customer bases. Ideal for individuals who prefer a softer sleep surface, the Nova Hybrid features a stretchy, plush quilted cover made in part from recycled plastic bottles. The comfort system consists of 1 inch of soft open cell AirScape polyfoam, another 1.5-inch layer of zoned AirScape polyfoam, and a 2-inch transitional memory foam layer featuring seven targeted zones. Like Casper’s other hybrids, the Nova contains a support core made from 6-inch pocketed coils reinforced by a 7-inch foam encasement.

The Wave Hybrid’s cover also incorporates recycled plastic bottles — up to 121 of them, to be exact. Like the Nova Hybrid, it features AirScape polyfoam and pocketed springs set in a dense foam encasement. However, The Wave Hybrid is intended for hot sleepers and those suffering from aches and pains, who may need more support and less contouring. The mattress’ 1-inch top comfort layer is made from open cell AirScape polyfoam laminated with cooling gel. The comfort system also contains a 1.5-inch layer of latex, a 1.5-inch, 3-zone memory foam layer, and 1.5 inches of zoned polyfoam containing targeted gel pods for pressure relief.

Lull

Lull’s flagship Original Mattress features a cooling cover made from a blend of polyester and rayon. Underneath is a 1.5-inch comfort layer consisting of gel-infused memory foam. Its 1.5-inch transitional layer is made from conventional blended foam, which is designed to mimic the feel of latex and prevent sleepers from sinking into the 7-inch polyurethane foam support core.

The Original Premium Mattress is similar to the flagship model, but contains 2 extra inches of foam padding in the comfort system. This creates a softer, more adaptive feel, but both mattresses are medium firm (6).

The Luxe Mattress is Lull’s sole hybrid model. The mattress contains memory foam and polyfoam comfort layers, a transitional polyfoam transitonal layer, and a support core with pocketed coils encased in dense foam. For each of these mattresses, the cover is composed of a polyester and rayon blend.

All Lull mattresses are CertiPUR-US certified. This means they are guaranteed to contain no harmful chemicals like formaldehyde, heavy metals, or ozone depleters.

In-Depth Ratings

Many mattress shoppers tend to prioritize certain features like firmness level and pressure relief. However, there are a host of criteria that can impact customer satisfaction, and some features may be more important to certain customers than others. Budget-minded shoppers, for example, may prioritize durability, while light sleepers might be more interested in motion isolating models. This section looks at some crucial factors to keep in mind while mattress shopping.

• Durability: While the most durable mattress isn’t always the most expensive option, some models and materials last longer than others. High quality components are crucial to a mattress’ longevity. Typically, mattresses featuring steel coils or high density foam last longer than lightweight, all-foam models. Customers who prioritize durability should also consider what type of foundation they want to use with their mattress. The wrong box spring or base can hasten damage.
• Motion Isolation: Motion isolation is important for individuals who share their bed with a partner or pets, especially those who are light sleepers. Some mattresses absorb motion and keep it from transferring throughout the surface, preventing one sleeper from waking up when the other stirs or gets up. Memory foam models often provide better motion isolation than hybrid or innerspring mattresses.
• Sex: Many couples want to ensure that their mattress is good for sexual activity as well as sleep. While every couple prioritizes certain mattress features, most prefer bouncy sleep surfaces that combine softness and support. Overly soft mattresses with too much contouring can prevent individuals from moving about freely in bed. In addition, some models with coil-based support cores can be noisy and indiscreet.
• Temperature Neutrality: Hot sleepers typically seek breathable sleep surfaces that stay cool throughout the night. Some mattresses absorb heat more than others, and temperature neutrality depends largely on the materials a mattress is made from. Memory foam tends to trap heat and cling to the sleeper’s body, while components like gel foam, latex, and cotton disperse body heat and increase breathability. Coil support systems may also encourage air flow.
• Pressure Relief: Athletes, side sleepers, and customers suffering from aches and pains benefit from mattresses offering above-average pressure relief. Very firm mattresses can make matters worse, causing pressure to build in areas like the shoulders and hips. In contrast, softer sleep surfaces that offer some contouring soothe and cradle these regions. Many mattresses also feature zoned coil systems that target pressure points.
• Off-gassing: Off-gassing refers to the unpleasant chemical odor released during the unboxing process. Most mattresses present some off-gassing, due to VOCs (volatile organic compounds) commonly used in materials like memory foam. Although odors usually dissipate within an hour or two, some mattresses retain their chemical smell for extended time periods. If you’re sensitive to smells or suffer from allergies, look for models with less off-gassing.
• Ease of Movement: Mattresses offering above-average ease of movement allow individuals to move about freely, without sinking into the sleep surface. All-foam mattresses and deeply contoured models tend to restrict motion, while firmer, more responsive mattresses provide better ease of movement.
• Edge Support: A mattress with strong edge support prevents sleepers from sinking inward or rolling off the edge. Good edge support also widens the usable sleep surface by several inches. Some, such as hybrid and innerspring models, feature reinforced perimeters that strengthen the mattress’ edge. In contrast, plush foam mattresses generally offer less edge support.

Prices and Sizing

While the most expensive mattress isn’t always the best, you often get what you pay for. Quality materials may cost more, but they often lead to a more durable product. Construction also influences price point. As the following tables demonstrate, hybrid models tend to cost more, as they incorporate heavier and more varied materials. All-foam mattresses generally feature simpler construction and fewer materials.

There are many other factors that can affect mattress price, such as size. A king size mattress will almost always cost more than a twin version of the same model.

Casper

Lull

Casper’s price points vary considerably between the budget Element and the company’s most expensive model, the luxury Wave Hybrid. Higher price tag notwithstanding, the Wave Hybrid boasts a wealth of features benefiting hot sleepers as well as those suffering from aches and pains. Along with zoned gel pad support and targeted coils, the model incorporates three layers of the company’s proprietary breathable, perforated AirScape foam and cooling gel. In contrast, both the Casper Original and Casper Hybrid feature a single layer of AirScape foam.

Comparable in cost to the Casper Original, the Lull offers significant pressure relief at a competitive price. Unlike Casper’s flagship model, the Lull features cooling gel-infused memory foam and a breathable cover, making it a good choice for hot sleepers. Some sizes of the Lull are also less expensive than their Casper Original counterparts, so individuals whose primary consideration is size may prefer the Lull.

Trial, Warranty, and Delivery

Purchasing a mattress online is a much different experience from buying one in a store. While many people find it a more convenient and comfortable way to shop, there are a few extra considerations that come with buying a mattress on the web. Let’s look at some now.

Shipping

Casper and Lull both ship for free to the contiguous US. Casper ships free to Canada as well.

Returns

Casper offers a full refund for all mattresses returned during the 100-night sleep trial period. Customers may initiate returns through the company website. Casper will contact a nearby charity or recycling center to pick up the unwanted mattress at a customer-designated date and time. Refunds are typically processed within two weeks.

Lull offers a 365-night sleep trial for the flagship mattress, which is one of the longest trial periods in the online mattress industry. Individuals who are unsatisfied with their purchase during this period may return their mattress and receive a full refund. Lull sends couriers to pick up and remove the unwanted mattress at no cost to the customer.

Warranties

A warranty is a written guarantee that a company will repair or replace all or part of a damaged or defective product within a defined period of time, free of charge or at a reduced cost. Most mattress warranties are limited, which means that they cover only certain defects, damages, or parts. For example, many limited warranties exclusively pertain to manufacturing defects or missing parts. Some mattress warranties are contingent on proper use, meaning that a mattress must be paired with a certain type of foundation to receive coverage.

Casper offers 10-year limited warranties for mattresses purchased directly from the company or authorized distributors. Casper’s warranty covers visible indentations larger than one inch, zipper defects, and defects in the cover fabric that do not result from improper use. Proper use is contingent on pairing the mattress with a suitable frame or foundation. The warranty does not cover comfort preferences, second hand mattresses, or mattresses sold as-is.

Lull offers a lifetime warranty, which covers the mattress for as long as the original owner retains possession of it. The warranty covers visible indentations more than 1 inch long that occur with proper use, along with fabric and zipper defects. The warranty does not pertain to minor cosmetic flaws, normal wear and tear, stains or damages inflicted by the owner, or personal preferences. It also does not cover allergies, sensitivities, or off-gassing. Owners don’t pay anything during the first 10 years of ownership if their mattress develops a defect. After 10 years, they’ll pay a flat fee of $75 if their mattress becomes defective and needs to be replaced.
