Let’s get started!

Construction: What’s It Made Out Of?

In the first category of our Lull vs Casper comparison review, we’ll be going over what each mattress is made of.

Lull Construction

The Lull mattress is a hybrid option featuring three individual layers of high-quality materials. Lull has constructed their mattress to offer the very best in comfort and support as well as proper alignment.

lull vs casper mattress comparison

Comfort Top Layer

The top of every Lull mattress is equipped with their comfort top layer, featuring 1.5” of blended memory foam and specialty foams. Lull has specifically designed this layer with top-notch comfort in mind. It provides perfect contouring to every body shape, avoids areas of pressure and numbness by distributing body weight evenly, and ensures you’re never left sore or achy from a too-soft surface by providing proper support under the neck and lower back.

This top layer of the Lull mattress also features most of the temperature controlling technology for the product – featuring infusions that are designed to enhance breathability and airflow, promising to keep you cool and comfortable.

Therapeutic Mid-Layer

Up next is Lull’s transition layer, made with 1.5” of blended premium foams. This layer helps to keep you comfortable and supportive in a couple of ways.

This is where you’ll find all of the crucial bounce-back and responsiveness in the Lull mattress. This layer has been specifically designed to respond to your body and any movement you make on the mattress. This helps to ensure that you’re not left with a sinking sensation or left feeling like you’re bouncing on a trampoline.

Core Support Base Layer

Bringing up the bottom of the Lull mattress is a 7” layer of high-grade core support foam. This layer’s thick density allows for zero motion transference through the night – ensuring that you’ll never be disturbed by your partner, pets, or kids moving around on the mattress. It also guarantees reinforcement of the entire mattress band ensures it will never sag by adding “strength. Durability, and structure.”

Casper Construction

The Casper mattress features four unique, individual layers that combine the very best qualities offered by both memory foam and latex – coming together to create one comfortable, supportive mattress.

Breathable Memory Foam

Casper starts their mattress off with a layer of ultra-breathable memory foam. Thanks to Casper’s specially formulated memory foam, featuring a unique open-cell construction, this layer can provide users with all of the great qualities you’ve come to expect from memory foam – perfect contouring, joint cradling, and pressure point relief.

But, their proprietary formula cuts out all of the most common memory foam issues, such as heat retention or a sinking feeling. Allowing the Casper mattress to simply provide unsurpassed comfort while always remaining cool.

Pressure Relieving Memory Foam

The second layer of the Casper mattress is constructed with their high-grade pressure relieving memory foam. This particular layer is where you can expect all of the deep, luxurious qualities that users have come to expect from memory foam. This layer works with the layer above to provide full-body pressure relief, joint cradling, and all-over contouring for an unsurpassed level of comfort.

Zoned Support Memory Foam

Up next is Casper’s layer of zoned support memory foam – the last layer featuring memory foam. Casper has designed this layer to be soft and cradling in all the right areas while remaining firm and supportive where it counts. This helps to ensure that you’re achieving proper alignment and the perfect amount of firmness to softness in all the right places.

Supportive Latex Foam

Casper harnesses the powers of latex in their last layer of supportive latex foam. This foundation layer guarantees that Casper users are getting that crucial firmness and support from their mattress. It reinforces the entire mattress, enhances the layers above, and guarantees necessary support and stability.

Who Wins?

In the construction section of Casper vs Lull, we’re giving Lull the win. They have fewer layers than their Casper counterpart, but we feel like Lull has better utilized their sections – ensuring that every inch of their mattress is working to keep you comfortable, supported, and healthy.

Temperature Control

In the next section of our Lull vs Casper review, we’ll take a look at the temperature control offered by both options to see which mattress will best keep you cool and dry.

Lull Temperature Control

Science has proven that the optimal temperature to achieve the best level of REM sleep is 69 degrees. Lull understands the need for a cool mattress to ensure a peaceful night’s rest and they’ve designed their mattress with that in mind.

They’ve infused the top layer of their mattress with a gel polymer that actually draws heat away from your body during the night and distributes it evenly through the mattress to guarantee that the surface always remains cool to the touch.

They also utilize top-tick fibers and an open-cell foam construction to increase the overall airflow and breathability of the mattress – which also enhances the performance of the gel polymer infusion.

Casper Temperature Control

While virtually every mattress on the market equips their product with some sort of temperature control, it’s often only the top layer or two. Casper, on the other hand, has made sure to equip every last layer of their mattress with some form of temperature regulation to guarantee that you’re always kept cool and dry.

To start things off, Casper’s top layer features an open-cell memory foam formula that actually harnesses the powers of convection and conduction to actively draw heat away from your body as you sleep. The layers of memory foam underneath are designed with top-notch breathability and airflow to ensure that heat is never trapped.

Casper even utilizes their very bottom layer to ensure that you stay cool and comfortable. Their latex layer is specifically designed to absorb the heat that’s drawn down from through the top layers and distribute it evenly through the very bottom of the mattress – farthest away from the skin.

Who Wins?

In the second category of our Casper vs Lull comparison, Casper has the leg up. We appreciate the technology that Lull has infused in their product. But, in the end, Casper simply utilizes more layers of their mattress to ensure that you’re getting the coolest sleep possible.

Overall Comfort: Firmness vs Softness

In this category, let’s compare the overall comfort as well as the firmness to softness ratio offered by the Lull vs Casper mattresses.

lull vs casper

Lull Comfort

The Lull company wants to ensure that their customers are not only comfortable and supported but maintaining a healthy sleep as well.

Their top layer of blended memory foam and specialty foams is designed to provide all of the unsurpassed joint cradling and pressure point relief that users have come to expect from the memory foam name.

The addition of blended specialty foams guarantees that your neck and lower back remain supported – which is uncommon with most foam options – to ensure that you’re never left achy or sore upon waking due to a too-soft surface.

Their transition and core support layers work together to ensure that you’re always getting all the necessary firmness, support, and stability. This combination guarantees that your entire body can always achieve proper alignment – allowing your muscles to relax completely.

Lull has also designed their mattress with ultra-responsiveness and bounce-back that guarantees you’ll never experience that dreadful foam sinking sensation and reduces motion transference throughout the mattress.

casper vs lull comparison

Casper Comfort

Casper advertises their mattress as a medium-firm option – which is the most popular firmness level among consumers and serves as a great place to start for those that are currently uncertain on their specific firmness needs.

Our “Construction” category above points out that the Casper mattress is primarily made of memory foam. Memory foam is well known for its unsurpassed ability to relieving pressure and contour perfectly to joints and problem areas. However, it can leave a lot to be desired in the firmness and support category.

Casper combats this issue with the addition of their zoned support and supportive latex foam layers. The zoned layer provides a level of firmness and support in all the right places while the latex foundation ensures that the entire mattress is properly reinforced and provides overall stability.

Who Wins?

When it comes to the overall comfort of Casper vs Lull, Lull takes the cake in this category. Both mattresses seem to be designed with the customer’s comfort in mind. But, Lull works hard to ensure that each layer is offering comfort, support, and proper alignment to ensure optimal relaxation and an overall healthier sleep.

Price: Casper vs Lull

Below, we’ll be taking a look at the price tags that come with the Lull vs Casper mattresses to see which option is the most budget-friendly.

Lull Price

Lull has done their best to ensure that their mattress is affordable for the average family. Each and every one of their size options comes in under $1000.

  • Twin – $500
  • Twin XL – $550
  • Full – $ 700
  • Queen – $800
  • King – $ 900
  • California King – $ 900

Every inch of the Lull mattress is working to keep you cool, comfortable, and supported. Given all the benefits and great qualities you can expect from the product, the price tag really can’t be beaten.

Plus, you can upgrade from a king to a California king-size for the same price. And if that isn’t enough to sweeten the deal for you, Lull offers financing on their products to help guarantee that almost anyone can afford the high-quality new mattress that they deserve.

Casper Price

When it comes to the average prices of a new mattress nowadays, Casper ranks somewhere in the middle. The queen-size option is just a hair under $1000 while their larger sizes are just over.

  • Twin – $595

Of course, Casper isn’t the cheapest option available on the market. But, they’re certainly not the most expensive either. Considering the high-quality construction, overall comfort, and temperature control in every layer – the price tag isn’t too astounding.

Plus, you can upgrade from a king to a California king-size at no additional cost.

Who Wins?

It’s pretty clear that Lull takes the win again in the price category of our Casper vs Lull comparison. Casper certainly isn’t the most expensive option on the market.

But, Lull keeps their prices safely under the $1000 and they even offer to finance your purchase to help guarantee that their product is affordable for the average working family.

Pros & Cons Of Lull vs Casper

Here, we’ll be taking a look at a few of the best reviews of the Lull vs Casper mattresses as well as going over a few of their most common problems.

lull vs casper

What Do Users Love About Lull?

Many Lull users claim that their mattress has given them the very best comfort and pain relief that they’ve ever experienced in any mattress. A lot of reviewers have been sure to point out that they’ve recently made the switch from popular, more expensive brands such as Serta or Tempurpedic. According to their experience, the Lull mattress performs just as well, if not better than their more expensive counterparts.

Several reviewers have also noted that they suffer from ailments or illnesses that cause chronic pain. After switching to the Lull mattress, they’ve noticed that a lot of their nighttime tossing and turning as well as their morning aches and stiffness has been greatly reduced or even completely eliminated.


  • According to customers, the Lull mattress can be expected to arrive at your doorstep with 1-4 business days
  • Users rave that the Lull’s temperature controlling properties perform perfectly
  • The Lull mattress is completely compatible with any flat surface including the floor

What Are The Common Downfalls Of Lull?

The Lull company compresses and vacuum seals their foam mattress. This packaging process makes shipping much easier, quicker, and cost-effective. It’s a common approach among direct-to-consumer companies.

But, this packaging process can cause fresh foam odors to become trapped. Upon breaking the seal, those odors are released and consumers often notice a chemical-like off-gassing smell. Lull recommends allowing the mattress to properly ventilate for up to 72-hours to allow the smell to dissipate. However, some Lull users have noticed that the odor still lingers several weeks later.

Lull does note that all of their mattresses are made wit Certi-PUR US Certified foam and the off-gassing odor is merely a result of the packaging process – the smell is in no way harmful to people or pets.  


  • Unfortunately, the Lull’s cover is not washable – you can only spot clean the mattress with cold water and a mild detergent
  • There is a layer of fiberglass flame retardant underneath their cover that should not be touched or disturbed – therefore Lull highly recommends that you never remove the cover
  • It’s recommended that the Lull mattress be rotated every 3-6 months, especially if you sleep with a partner

What Do Users Love About Casper?

Users love their Casper mattress, that is easy to see. But, after a scroll through the review section, it seems their biggest praise comes down to their perfect balance of softness and firmness.

Casper worked diligently to create a mattress that provided the best in both comfort and support. According to real-life reviews, they hit the nail on the head. In fact, a large handful of reviewers pointed out that they suffer from ailments such as arthritis or fibromyalgia which causes significant pain and stiffness.

Thanks to their Casper mattress, much of their nighttime tossing and turning as well as their morning stiffness has been greatly reduced or even completely eliminated.


  • Every layer of the Casper mattress is designed to keep you cool, comfortable, and dry
  • You Casper purchase is protected by an industry-standard sleep trial and warranty
  • The Casper mattress offers the perfect harmony of comfort and support – backed by real-life customer reviews
  • According to Casper customers, their customer service department is always friendly, courteous, timely, and happy to help with even the smallest of issues

What Are The Common Downfalls Of Casper?

We found very few complaints pertaining to the actual performance of the Casper mattress. But, we did notice that a large majority of customers noticed a very strong chemical-like odor upon opening their mattress.

Direct-to-consumer mattresses, especially those with a foam construction, are commonly compressed and vacuum-sealed for easier and cheaper shipping. While it’s not necessarily a bad tactic, it can allow for a “fresh-foam” odor to become trapped in the packaging. When the seal is broken, the odor is released, causing a harmless “off-gassing” smell.

Usually, this odor will dissipate within 48-72 hours with adequate ventilation. However, many Casper users have complained that odor did not dispel properly – some claiming that it even lasted upwards of 2 weeks.


  • Because of the way the Casper mattress is compressed for shipment, it can take up to 72-hours for the mattress to fully expand and be ready for use
  • Like many foam options, Casper lacks sufficient edge support leaving users susceptible to rolling off the edge
  • Users that sleep with a partner that’s larger in size have noticed that the mattress has a tendency to lean significantly
  • Unfortunately, some users claim that their Casper mattress broke down in as little as 6 months

About The Companies

In the last category of our Lull vs Casper comparison review, we’ll go over a few of the most important details surrounding the two mattress companies.

Lull Company

Sven Klein found himself shopping for a new mattress with his wife for the first time since they’d bought one knew as a couple. It didn’t take long for all of the memories of the first excursion to come rushing back to him and have him dreading the experience before it truly even got started.

It turned out, his dread wasn’t baseless. There he was for the second time, surrounded by pushy, over-eager salesmen, inconsistent and completely inflated prices, and expected to choose a mattress based off of 10 minutes spent lying on it in a bright, crowded store.

Klein and his wife didn’t come home with a mattress that day But, Klein did leave the store with what he describes as his “aha moment”. After that unpleasant experience, Sven Klein set out to reinvent the way we buy a new mattress. He founded the Lull mattress company that would provide customers with a high-quality product, allow them to test it sufficiently in their home, and made it affordable for the average working family.

casper vs lull

Casper Company

The creators of the Casper mattress found themselves in the same position as many online mattress company founders – they were fed up with the way we were expected to buy a new mattress. The big box stores were full of pushy salesmen, the prices were way too high, and the 10-minutes test runs were insufficient.

So, in 2014, 5 friends came together to create a solution to this common problem. They founded the Casper mattress company that would allow consumers to purchase a high-quality mattress at an affordable price – and allowed them to properly test the product in their home.

Since their founding, Casper has been recognized by Good Morning America, The New York Times, and Forbes. In 2017 they received the title of one of the Most Innovative Companies by Fast Company and received Good Housekeeping’s Lab Pick in 2018.

When it comes to Lull vs Casper, both mattresses are truly great options. They both offer high-quality craftsmanship and construction, temperature controlling properties that truly work, and a high level of comfort.
