We Tested (and Rated!) Every Mattress at Casper

Buying a mattress sounds intimidating, especially if you’re going in person to test out a bunch of different options and aren’t sure which brand you want to focus on. To make it a bit easier on yourself, consider ordering online and getting a mattress that comes delivered in a box. Casper was one of the original direct-to-consumer (DTC) mattress brands that became popular in the mid-2010s, and it has remained a popular choice for those looking to order a mattress-in-a-box.

As part of our Personal Shopper series, we sent two editors to test out Casper mattresses in person at the Casper store in Manhattan’s NoHo neighborhood. They spent time on all six Casper mattresses, evaluating the firmness, design, motion transfer, and edge support of each one. Read on for all of our insights, and get ready to upgrade to the bed of your dreams.

Casper’s mattresses are simple and unfussy, with both foam and hybrid options available for all types of sleepers and firmness preferences. In particular, Casper stands out for its Snow line, which features cooling technology that is designed to keep hot sleepers comfortable. Casper offers a 100-night trial period for its mattresses, plus in-home delivery and setup if you’d rather not deal with unpacking it yourself.

In addition to mattresses, Casper sells seven different pillows, as well as sheets, duvets, mattress protectors, bed frames, and even lighting to outfit your entire bedroom. We’ve tested and written about several Casper products over the years, including its original hybrid pillow, cooling hybrid pillow, upholstered bed frame, attachable headboard, and viral Glow Light.

We judged every Casper mattress based on the following criteria:

• Feel: Is the mattress firm, soft, or somewhere in between? Does it have extra cushioning? Is it comfortable no matter the sleep position?
• Support: Does the mattress effectively cradle pressure points? Does it feel comfortable to lie on?
• Materials: What is the mattress made from? Is it a hybrid mattress? Does it have cooling properties?
• Safety: Do the materials in the mattress have any certifications?

Each Casper mattress was tested by Apartment Therapy editors Lizzy Francis and Sarah Everett. Lizzy is Apartment Therapy’s lifestyle editor, covering real estate, cleaning, organizing, and shopping. She has been with Apartment Therapy since May 2024, and was previously an editor at Fatherly. Sarah is the home projects editor, and covers Before & Afters, DIYs, home projects, and design trends for Apartment Therapy. She has a master’s degree in journalism and has been on the Apartment Therapy editorial team since 2020.

Lizzy’s thoughts: Casper’s most affordable mattress is simply called The One, and it offers a soft, responsive feel that still provides support. As someone who doesn’t like all-foam mattresses, I was surprised at just how supported I felt while lying down — my spine maintained its natural curve while my joints felt cushioned. Casper describes The One as having a medium-firm feel, but I actually found it to be pretty soft (or maybe I’m just used to a firmer mattress!). 

It features three layers of breathable foam, including an open-cell foam layer that’s designed to prevent overheating. Although I couldn’t test its cooling features overnight myself, I can see how the foam encourages better airflow — although no foam mattress will be as cooling as a hybrid or innerspring model. I also noticed that this mattress has pretty good edge support, especially considering the price. Casper recommends The One for back and stomach sleepers, but I think side sleepers would be just fine as well. 

Specifications: 

• Type: Foam
• Sizes: Twin, twin XL, full, queen, king, California king, split king
• Height: 11 inches
• Firmness: Medium-firm

Lizzy’s thoughts: The Cloud One offers a bit of an upgrade to The One, but is still priced pretty affordably. It has more of a springy, medium-soft feel that balances plush comfort with solid support — although I actually think that it feels slightly firmer and more buoyant than The One. It responds similarly to a latex mattress, despite being all-foam. That feel can be attributed to the cloudlike “foam pillars,” which sit in the mattress’s core and add a touch of luxury compared with typical flat foam layers. 

Like The One, the Cloud One offers good edge support, minimal motion transfer, and a breathable foam layer for better airflow. Casper says that it’s suitable for all types of sleepers, and I agree that I felt supported in all sleep positions. Although I’m not personally a fan of all-foam mattresses, I think this one stands out due to the foam pillars and relatively affordable price point.  

Specifications: 

• Type: Foam
• Sizes: Twin, twin XL, full, queen, king, California king
• Height: 11 inches
• Firmness: Medium-soft

Lizzy’s thoughts: This one is my favorite! The Dream is a springy hybrid mattress that combines supportive coils with responsive foam, which in my opinion is the best type of mattress. It offers excellent edge support, virtually zero motion transfer, and targeted ergonomic zones that provide softer cushioning at the shoulders and firmer support at the hips. I think side, back, and combination sleepers would most benefit from this feature, although Casper says it’s suitable for all sleep positions. 

The Dream is advertised as having a medium feel, but I think it’s more on the medium-firm side. I felt immediately supported, and my joints didn’t feel like they were sinking in at all. Another nice feature was the jersey cover, which looks and feels cozy but is thin and airy enough to be considered breathable. And of course, the Dream comes with the same cooling foam that all Casper mattresses have, but with the addition of flexible coils for even better airflow.

Specifications: 

• Type: Hybrid
• Sizes: Twin, twin XL, full, queen, king, California king, split king
• Height: 12 inches
• Firmness: Medium

Sarah’s thoughts: Looking for a cooling mattress? Then Casper’s Snow line is for you. Like the Dream, it’s designed with three ergonomic zones — but unlike the Dream, it comes with added cooling technology. These features include three temperature-regulating bands (called HeatDelete bands) placed on the foam layers that pull away heat while you sleep, as well as another layer of heat-absorbing material. While I couldn’t sleep on it overnight, I was still impressed by the design, although I preferred the Snow Max (more on that one below).

This mattress has a medium feel with solid support, good edge stability, and excellent motion isolation. I found it to be more on the medium-firm side, though, especially compared with the Snow Max, which is softer. Casper recommends it for all sleeper types — hot sleepers will love the cooling technology, side sleepers will benefit from the ergonomic zones, and stomach and back sleepers will like the support of the medium firmness level.

Specifications: 

• Type: Hybrid
• Sizes: Twin XL, full, queen, king, California king, split king
• Height: 12 inches
• Firmness: Medium

Sarah’s thoughts: The Dream Max offers a soft, plush feel that gently cradles the body while maintaining proper spinal alignment, making it especially comfortable for side sleepers and those prone to back pain. Like the standard Dream mattress, the Dream Max has ergonomic zones, with more support under the hips, waist, and lower back — but the Dream Max takes it a step further with two layers of zoning instead of one. It also has channels cut into the foam, which allow for better cradling. If you like more of a sink-in feel, you’ll love this mattress!

As someone who is a pretty still sleeper, one of my biggest problems is waking up feeling hunched and stiff, but this mattress seems like it’s comfy and supportive enough to prevent that from happening. Despite its softness, it delivers impressive edge support, though the motion isolation could be better. I think this one had the most noticeable motion transfer out of all the mattresses we tested, and I could very much feel Lizzy move around next to me. So, this might not be the best option for light sleepers who share a bed. Still, I love how soft and cushioned the Dream Max is, and I highly recommend it if you’re looking for a true luxury feel.

Specifications: 

• Type: Hybrid
• Sizes: Twin XL, full, queen, king, California king, split king
• Height: 14 inches
• Firmness: Medium-soft

Sarah’s thoughts: If you’re a truly hot sleeper or live in a climate that’s hot and humid year-round, then the Snow Max is for you. Unlike the standard Snow mattress, the Snow Max is noticeably cool to the touch — so much so that I could feel it working through my long sleeves. It has similar features to the standard Snow, including a cooling cover, temperature-regulating layer, and HeatDelete bands, but the Snow Max has six bands instead of three for ultimate heat absorption. 

In terms of comfort, the Snow Max offers a soft, sinking feel that’s similar to that of the Dream Max, with two layers of zoned support and cut foam for optimal cradling. It feels like a cloud, and I personally prefer it to the firmer feel of the standard Snow mattress (although I can see how those who don’t like a sink-in feel would prefer the Snow). I noticed a lot less motion transfer compared with the Dream Max, but the edge support was weaker and I felt like I could easily slide off. Overall though, this is a plush, ultracooling option that hot sleepers will appreciate.
