Casper Dawn Mattress Construction
The Casper Dawn mattress includes a knit cover and three layers of foam that provide support and pressure relief. We’ve researched how the mattress is made and discuss the construction details below.
Knit Cover
The soft cover gives the Casper Dawn mattress a cozy feel from the start. Made of a polyester/spandex blend, it has a heathered white knit top with an elegant waterfall edge. The border is 2/3 woven fabric and 1/3 colourblock heathered charcoal fabric. The Casper logo is heat stamped on the side.
Casper Signature Foam
Next is the soothing, 1.5-inch layer of Casper Signature Foam. It relieves pressure points as it responds to your changing positions. The resulting pressure relief feels like sleeping on a cloud. Plus, it’s made of breathable polyurethane foam that won’t trap heat as it cushions your body.
High Quality Transition Foam
More pressure relief is provided by the high quality transition foam layer. The 1.5-inch breathable foam layer eases the transition from pressure relief to support. It also prevents motion from transferring to the other side of the mattress because it adapts as you move around.
ProSupport Foam
The Casper Dawn mattress is built to last, with a 6-inch layer of breathable ProSupport foam. This durable foam provides support and prevents sagging and dips in the mattress. This consistent support helps maintain proper alignment in the spine, hips, and shoulders.
Medium-Firm Feel
Of course, the right firmness level for you is a matter of personal preference. The Casper Dawn mattress has a medium-firm feel. Not too firm and not too soft, it’s a great choice if you’re not sure which firmness level you prefer. It’s also helpful for couples with differing mattress preferences.
Your Choice of Casper Dawn Mattress Sizes
There’s a Casper Dawn mattress size for virtually every bedroom or sleep style. Whether you’re comfortable on a twin size mattress or prefer to stretch out on a large sleep surface, you can find the mattress size that’s right for you. The Casper Dawn is available in the following sizes:
- Twin: 37.5″ W x 74.5″ L x 9” H
- Twin XL: 37.5″ W x 79.5″ L x 9” H
- Full: 52.5″ W x 74.5″ L x 9” H
- Queen: 59.5″ W x 79.5″ L x 9” H
- King: 75.5″ W x 79.5″ L x 9” H
- Cal King: 71.5″ W x 83.5″ L x 9” H
Casper Dawn Mattress Review: Pros and Any Limitations
Now let’s see what it’s like to actually sleep on the Casper Dawn mattress. Our team has researched and reviewed the mattress. In the following sections, we share our opinion of its pros and any limitations.
Cozy and Stylish Cover
We like how Casper has added stylish touches to the cover of the mattress. The waterfall edges and heathered white knit top give the cover a simple elegance. The soft, cozy material adds to the overall comfort of this foam mattress.
Pressure Relief
We’re impressed with the pressure relief provided by the Casper Signature Foam and the high-quality transition foam. Both layers cushion and cradle the spine, hips, and shoulders, to help prevent aches and pains from pressure points. The transition foam enhances the pressure relief by smoothing the shift to the support layer. The top two layers of foam combine to provide consistent, evenly distributed pressure relief and comfort.
Breathable Foams Keep You Cool
Unlike some foam mattresses, the Casper Dawn allows plenty of air circulation. The breathable polyurethane foam lets airflow carry away body heat. If you tend to sleep hot, we think you’ll appreciate how the three foam layers regulate temperature. Thanks to the breathable materials, you don’t have to wake up hot and sweaty.
Evenly Distributed Support
With a durable ProSupport Foam layer, the Casper Dawn mattress balances comfort with support. It resists dips and sags, maintaining evenly distributed support. Your shoulders, hips, and spine stay properly aligned, allowing you to rest comfortably.
Motion Isolation
If you share a bed with a spouse or partner, the high-quality transition layer can help you sleep soundly — even when your partner is tossing and turning. The responsive foam layer adapts as you move, so the motion is not felt on your partner’s side of the bed. Even if you or your partner gets out of bed, the other partner can sleep undisturbed.
CertiPUR-US® Certified Foams
Casper uses planet-friendly materials in their Dawn mattress. The foams are CertiPUR-US® certified, which means that they meet strict emissions and chemical content standards. Canadians can have peace of mind knowing that your mattress is free of VOCs, formaldehyde, and other harmful substances.
More Accessible Price
We like how Casper has designed its Dawn mattress to include premium materials at a more accessible price point. At 9 inches thick, the mattress does not have the high profile of more expensive models. However, it still contains the quality materials — such as Casper Signature Foam — of higher-priced models. The more affordable price makes the Casper Dawn mattress a realistic option for more Canadians.
Shipped In a Box
Casper ships the Dawn mattress in a box, vacuum compressed and wrapped in plastic. It conveniently arrives at your door, whether you’re at home, at work, or running errands. When you take it out of the box, be prepared to wait a few hours for the mattress to expand. It may also take a day or so for a slight odour or off-gassing to air out.
100-Night Sleep Trial
When you buy the Casper Dawn mattress, you can literally sleep on the purchase decision for more than three months. The mattress comes with a 100-night sleep trial, which takes effect on the delivery date. After a 30-night adjustment period, you can return the mattress during the trial period.
Casper will arrange a free pickup and full refund. They will even donate the mattress to charity, when possible.
10-Year Limited Warranty
The Casper Dawn mattress also comes with a 10-year limited warranty. During the warranty period, Casper will repair or replace a mattress that is defective due to poor workmanship or materials. The warranty does not, however, cover defects caused by misuse or improper handling. Always read the warranty terms, which can change at any time, before buying a mattress.

Concluding Thoughts on the Casper Dawn Mattress
With its lower profile and simplified construction, the Casper Dawn mattress offers quality at a more accessible price. You’ll still see some of the best foam mattress features that the company offers, such as the Casper Signature Foam.
We think you’ll like how the three layers of polyurethane foam allow airflow to regulate the mattress temperature. You can sink into the Casper Signature foam without waking up overheated. Since the foams are CertiPUR-US certified, you can also rest easy knowing the mattress is environmentally friendly.
The comfort and transition layers combine with the ProSupport layer to provide evenly distributed support and pressure relief. The spine, hips, and shoulders stay properly aligned as the Signature Foam cradles the body.
The foam layers add up to a medium-firm feel that is not too soft and not too firm — an ideal compromise for couples who can’t agree on mattress firmness. We also think that couples will appreciate the motion isolation provided by the responsive Signature Foam layer.
The knit cover adds a soft, cozy touch to the Casper Dawn mattress. It completes the overall comfort of the mattress. The slightly stretchy material keeps the surface comfy and soothing.
We think you’ll appreciate the convenience of shipping in a box to your door. You can buy the mattress without the hassle of transporting it home or rescheduling your day for a delivery team.
Shopping for the best foam mattress is easier when the mattress comes with a 100-night sleep trial. Casper does ask that you keep the mattress for a 30-day break-in period. After that, you can return the mattress for free during the trial period.
The 10-year limited warranty is another helpful feature. You can have confidence in your purchase because the mattress comes with a 10-year limited warranty. There’s usually no charge for replacing or repairing a mattress that is defective according to the warranty terms.
Our team has researched and reviewed the Casper Dawn mattress. In our opinion, it offers the comfort, support, and temperature one would expect from a top foam mattress. We recommend the Casper Dawn as a product of value.
