Loom & Leaf vs. Casper: A Point-by-Point Comparison

So you’ve explored your options and decided a memory foam mattress is the right one for you. Good choice! People love memory foam for its pressure-relieving comfort and unique contouring ability. (And people who love it really love it: Memory foam mattress owners report the highest levels of satisfaction with their sleep surface.)

But not all memory foam mattresses are alike. Here’s a closer look at the key differences between Saatva’s Loom & Leaf memory foam mattress and The Casper memory foam mattress.

The most luxurious memory foam with adaptive cooling & body-hugging support



Comfort is a tricky thing—what feels good to one person may not feel all that great to another. While some mattresses aim for a universal comfort level, others offer a range of firmness options, so you can tailor your sleep to your personal needs and preferences. Other factors that determine the comfort of a memory foam mattress: the number and type of layers, how it keeps you cool while you sleep, and whether it provides support where you need it most: in the all-important lumbar zone.

Do I have a choice of comfort options?

Loom & Leaf: Yes

Casper: No

Loom & Leaf comes in two comfort levels: relaxed firm and firm. Relaxed firm is the most popular choice, as it offers a combination of cushioning for pressure relief and contouring support that works for back, side, and stomach sleepers. Firm is for anyone who like the feel of a firm mattress or for stomach sleepers who need added support. The Casper comes in one comfort level. It’s for those who prefer a medium-firm mattress.

The bottom line: More comfort levels equals more chances for you to find your best mattress match. (Need help figuring out which comfort level is right for you? Here’s how to choose based on your sleep style and body type.)

How many layers of foam are in the mattress?

Loom & Leaf: Four

Casper: Four

From the bottom up, the 12-inch Loom & Leaf mattress has four layers. (Here’s a detailed view):

  • a 5.5-inch support base made of 1.5-lb. density polyurethane foam;
  • a 2-inch transition layer of 1.8-lb. polyurethane foam;
  • a 2.5-inch layer of 5-lb. viscoelastic memory foam;
  • a 2-inch layer of 4-lb. convoluted (wavy) memory foam infused with cooling gel.

The 10-inch Casper mattress has four layers. Starting from the bottom, it has:

  • a 5-inch support base made of 1.8-lb. density polyurethane foam;
  • a 1.5-inch transition layer made of 2.5-lb. density polyurethane foam;
  • a 1.5-inch layer of 3.5-lb. density memory foam
  • a 1.5-inch layer of 3.5-lb. density polyurethane foam

The bottom line: The number of layers, and what’s in them, determine how a mattress feels, how well it performs, and how long it lasts. (Despite the name, memory foam mattresses are not made only from memory foam. If they were, they’d be too soft to sleep on.) Typically, only the upper, or comfort, layers contain memory foam, while the base support layers are made from high-density polyurethane foam. The denser the foam, the more durable and supportive the mattress. The foam in Loom & Leaf is higher density than the foam in The Casper mattress, which is designed so it can be compressed and packed in a box.

What kind of lumbar support does the mattress have?

Loom & Leaf: Spinal cooling gel and Lumbar Zone® Quilting in the center third of the mattress provide targeted back support.

Casper: The Casper’s transition foam layer has Zoned Support™ for added firmness in the middle of the mattress.

The bottom line: Lumbar support is crucial when it comes to picking a memory foam mattress—or any mattress for that matter, especially if you experience pain in your back, shoulders, or hips while you sleep. Adequate lumbar support assures that the spine stays in neutral alignment, which means you won’t wake up sore or stiff. (Here’s how to keep pain from ruining your sleep.)

What does the mattress do to keep you cool?

Loom & Leaf: The top layer of Loom & Leaf contains a nontoxic cooling gel swirled into the memory foam. A panel of the same gel is layered onto the foam in the center third of the mattress, where body heat is concentrated, for added cooling and spinal support. Then the whole mattress is wrapped in organic cotton for maximum breathability next to the skin.

Casper: The top layer consists of a breathable, open-cell comfort foam that promotes airflow.

The bottom line: The more cooling features a mattress has, the more comfortably you’ll sleep. Sleeping hot is a common concern when it comes to memory foam. That’s because memory foam responds to temperature, softening as it warms and molds to your body. While contouring is what many people love about memory foam, it can also trap and retain heat close to the body.


Beyond judging a new mattress by comfort, it’s important to ensure your memory foam mattress is truly a quality product. You’re going to spend a lot of time on your mattress (here’s how much sleep you really need), so you want to choose a mattress that’s built to last. Understanding what your mattress is made of is a good indicator of mattress quality.

What is the density of the foam in the mattress?

Loom & Leaf: Loom & Leaf’s two memory foam layers are 5 lbs. per cubic foot and 4 lbs. per cubic foot, respectively. The high-density foam support layers are 1.5 lbs. and 1.8 lbs. per cubic foot.

Casper: Casper’s memory foam layer is 3.5-lb. density. The polyfoam layers range from 1.8 to 3.5 lbs.

The bottom line: The higher the foam density, the more supportive and durable the mattress. Loom & Leaf uses higher-density foam than Casper, which uses lower-density foam so that it can be more easily compressed into a box.

How soon can I sleep on the mattress?

Loom & Leaf: Immediately

Casper: After it’s unboxed, taken out of plastic, and expanded

The bottom line: A multi-layer, high-density foam mattress can’t be flattened and shipped in a box. Loom & Leaf mattresses are never crushed or compressed, so you can sleep comfortably on them from the moment they’re delivered. Beds in boxes, like The Casper, need a few minutes to inflate once they’re taken out of the packaging. They also need some time to air out: Vacuum sealing and wrapping in plastic concentrates odors. (Learn about mattress off-gassing here.) Casper recommends leaving the mattress in “a well-ventilated room” until any smell dissipates.

What is the flame retardant made of?

Loom & Leaf: Natural thistle

Casper: Woven silica sock

The bottom line: When it comes to mattresses, toxic ingredients are most likely to turn up in fabrics and components treated with fire retardants, such as covers and foam padding. Loom & Leaf’s fire barrier is made from an all-natural material—thistle pulp woven into a mesh—without the use of harmful chemicals. Casper uses a woven silica sock that does not contain any flame-retardant chemicals.

What is the mattress cover made from?

Loom & Leaf: Organic cotton

Casper: Polyester

The bottom line: Cotton is the most popular bedding material because it’s naturally cool and breathable. Organic cotton has the added benefit of being produced without the use of pesticides or chemical fertilizers, which means it’s hypoallergenic and unlikely to irritate the skin. Loom & Leaf’s fabrics are certified by Oeko-Tex to be free of harmful chemicals. The main ingredient in The Casper cover is polyester. (Here’s what you need to know about organic mattress components.)


Last but certainly not least, we come to value. When you’re buying a new mattress, cost is often one of the biggest factors. But to decide whether you’re getting the most for your money, consider comfort guarantees, delivery policies, warranty terms, and customer service.

How much does the mattress cost?

Loom & Leaf: $2,395 (queen)

Casper: $1,295 (queen)

The bottom line: The Loom & Leaf mattress costs more than the Casper. That’s because it’s a premium mattress made with quality materials, hand-delivered and set up in your home. Don’t get us wrong: boxed beds are a great choice for some shoppers—they’re convenient and affordable. But at Saatva, we believe you can’t fit true luxury into a cardboard box.

How is the mattress delivered?

Loom & Leaf: Free white-glove delivery

Casper: Free shipping via UPS

The bottom line: Saatva does all the heavy lifting for you—from delivery of the Loom & Leaf mattress to set up to taking away your old mattress. Casper is delivered to the customer’s doorstep, but setup is your responsibility. A boxed queen-size Casper weighs 92 pounds.

How long is the at-home trial period?

Loom & Leaf: 365 days

Casper: 100 days

The bottom line: With Loom & Leaf, you get 365 days to decide whether or not you’re happy with your mattress. If not, we will exchange it for another mattress or take it away for donation or recycling. In the case of a return, you are responsible only for a $99 processing fee. Casper will arrange for returned mattress pickup through a local charity or recycling party with no extra charge.

How long is the warranty?

Loom & Leaf: Lifetime warranty

Casper: 10 years

The bottom line: The Loom & Leaf memory foam mattress carries a lifetime warranty. The warranty works like this: If a mattress is deemed defective during the first two years, Saatva will replace it with a brand-new mattress, free of any charge. Starting in year three and for as long as you own your mattress, Saatva will repair and re-cover your mattress. You will be responsible only for a $149 processing fee. Casper offers a 10-year warranty and waives shipping costs associated with mattresses returned under the warranty.
