About the Casper Element Pro mattress
Casper is one of the original mattresses in a box, launching its first mattress in 2014. Now Casper sells many mattresses, including upgrades of its originals, as well as bedding products like pillows, sheets and blankets, and dog beds.
The Element Pro, a 10-inch foam mattress features three layers: an “Airscape” top of viscoelastic foam designed to diffuse heat throughout the night, a memory foam layer for pressure relief, and a durable foam base for support.
It’s designed with feedback from the original Casper Element mattress in mind. Customers appreciated the first Element for its plush surface that cushioned a variety of sleep positions. The company claims its Element Pro mattress carries on the best features of its predecessor while offering an additional support layer to promote a more responsive sleep.
What we like about the Casper Element Pro mattress
It relieves pressure
The Casper Element Pro is a soft all-foam mattress, so it makes sense that it wouldn’t put uncomfortable pressure on, say, the hips and shoulders of a side sleeper. Foam mattresses, particularly ones made with memory foam, typically absorb weight and cushion around the body, providing a sort of sinking-in sensation.
Think of it as a giant sponge: If a person sleeps on any given squishy surface, of course they’re going to feel all that joint and spine pressure dissipate.
Here at Reviewed, we test pressure relief by moving weights, like a barbell, across the mattress and measuring how the weights sink into the surface. This gives a sense of how various parts of the body would be supported or cushioned. Based on our lab tests, the Element Pro mattress showed signs of providing such pressure relief.
What we don’t like about the Casper Element Pro mattress
It doesn’t diffuse heat well
Foam mattresses usually have a difficult time diffusing heat. The material itself is dense, which discourages airflow, so a body’s warmth becomes trapped and heats the surface and you can’t find any cool spot to lie in. Unfortunately, our tests indicate that the Casper Element Pro mattress, even with its supposed Airscape heat-diffusing layer, fails to overcome this issue.
For this test, we warm heating pads to body temperature and place them around the mattress’s surface. This helps us measure the rate at which temperatures decrease over time. And some pads reside inside pillowcases and blankets, giving us a sense of what it would be like for someone sleeping on this mattress at home. From what we can tell, Casper’s Element Pro mattress lacks the ability to diffuse heat throughout the night.
It offers little motion isolation
If you share your bed with a partner or pets, you’ll likely value a mattress’s ability to isolate motion so that when your bedmate moves, you don’t feel a ripple effect. While foam mattresses can often isolate motion thanks to their cushioning surfaces, the Casper Element Pro mattress didn’t score particularly well here.
We noticed that the mattress didn’t absorb all of the force from our 150-pound punching bag, which we dropped onto one side while recording the force distribution on the other side. This indicates that a partner or pet’s tossing and turning may disturb your slumber.
Similarly, when lying on the Casper Element Pro mattress, we noticed if we shifted our position at all, we could feel the slatted bed frame beneath us. This suggests the mattress has issues absorbing motion throughout the entire 10-inch depth, which we found puzzling.
It provides basically no edge support
Edge support is an important attribute for anyone who likes to sit or lie along the sides of their mattress, but it’s essential for people with mobility impairments who use the edge to get in and out of bed. Foam mattresses often struggle with it because they lack the framework and coils of a hybrid or innerspring mattress.
But even we were surprised by how poor the Casper Element Pro mattress’s edge support was. The edge collapsed easily under the weight of the 150-pound punching bag we laid along it. At one point, we left the punching bag near the edge of the mattress (but not teetering on it) and walked out of the room. When we came back a few minutes later, the punching bag was on the floor. So either our Cambridge lab is haunted, or the Casper Element Pro mattress can’t hold weight near its sides.
What other reviewers are saying about the Casper Element Pro mattress
Because the Casper Element Pro mattress is new, it does not have an average star rating or many reviews on the Casper website yet. Early reviewers say the Element Pro is a bit firmer than expected, but the surface remains soft enough to support most sleeping positions. Some customers also appreciate the more affordable price as compared to Casper’s other mattresses.
A few reviewers note that the mattress may not be best for side sleepers and heavier people who require more support from a bed, while one says it “supports every point of contact, helping to prevent new back pain.”
What is Casper’s return policy and warranty?
Like other mattress-in-a-box companies, Casper offers a 100-night trial but asks customers to sleep on the mattress for at least 30 nights before attempting to return it. The company offers a 10-year limited warranty, which is only valid for the original purchaser and product.
The warranty covers defects attributed to its manufacture, such as splitting foam or a visible indentation greater than 1 inch that isn’t associated with an improper or unsupportive bed frame and base. The warranty doesn’t cover general wear and tear over time. It also nulls if the mattress is sold from the original purchaser.
In the event of a defect, customers can either request a replacement of the same model or upgrade to a more expensive replacement by paying the difference between their original purchase price and the current cost of the upgraded mattress.
Should you buy the Casper Element Pro?
No, there are better alternatives
Based on our lab results and experiences, we don’t think the Casper Element Pro mattress is worth it. Even with its ability to relieve pressure, its poor scores in heat diffusion, motion isolation, and edge support make it a lackluster option—especially when there are so many other foam mattresses to choose among.
Our favorite foam mattresses include the Lull Original, which sleeps cool but may be too firm for some sleepers. We also like the Tuft & Needle Original Mattress, which provides balanced support for any sleep position but retains some heat.
