Read our full Casper mattress review.
Mattress firmness is measured on a 1–10 firmness scale, with higher numbers yielding a greater firmness level. The Casper Original mattress falls at a 6/10, meaning it’s a medium-firm mattress. Medium-firm beds are said to have the universal firmness because it’s the feel that most sleepers prefer. The Helix Midnight is also a medium-firm bed with a 6/10 firmness level.
While the Helix and Casper have similar firmness levels, the way that they feel is noticeably different. The Helix mattress has a top layer of medium-firm memory foam that cradles the body for a hugging feel. Casper uses a polyfoam top layer that’s more responsive, which means the foam responds more quickly when you move.
The top layer of foam in the Casper mattress has more of a traditional pillow top feel rather than a memory foam cradle. Underneath this soft foam is Casper’s Zoned Support memory foam, which brings extra support to the body’s trunk and more contouring at the top third and bottom third of the mattress.
The Helix’s conforming feel brings wonderful pressure relief for side sleepers and a moderate hug for back sleepers who like a traditional memory foam feel. The spring support system underneath offers responsiveness so you won’t feel stuck.

Both the Helix and Casper mattresses do an excellent job stifling motion where it occurs, ensuring that it doesn’t spread to the other side of the mattress. Light sleepers who sleep with a partner, child, or pet sleep best on mattresses that dampen motion (like the Helix and Casper).
While we believe both beds will work for most couples, the Helix spreads just a bit more motion because of its supportive layer of springy coils. If your primary concern is motion transfer, the Casper may be the better bed. See our picks for the best mattress for couples that isolate motion and accommodate two sleepers well.
Helix and Casper both excel at delivering sturdy and comfortable edges. Both beds allow couples to spread out and lie along the edges, and they’re each stable enough for people to use the perimeter for support while getting into or out of bed.
The Casper and Helix both deliver above-average pressure relief, offering the cushiony feel and cradling loved people with joint pain. Because the Helix mattress has a layer of memory foam along the top, it’s the best choice for lightweight folks who need cushioning.
The Casper’s polyfoam requires a bit more weight for maximal give, so it’s best for side sleepers who weigh between 130–230 lbs. The Casper is a good mattress for lower back pain and for those who have sensitive areas along their spines, while the Helix provides a more general close, conforming feel.
The Casper’s ergonomically Zoned Support system provides superior spinal alignment compared to the Helix, at least for most sleepers. Casper’s added firmness at the body’s core helps keep stomach sleepers’ hips from sinking in too far, which prevents the spine from arching out of alignment. Also, its softer feel at the head and foot of the mattress means side sleepers experience more give at their shoulders, which helps to keep the spine aligned.
While the Casper is generally better for proper alignment—and with it, back pain relief—the Helix does a remarkable job supporting the spines of back sleepers and side sleepers. These people are likely to find good alignment on either mattress. If you wake up in pain, see the best mattresses for back pain.
Overall, our mattress testing team thinks the Helix mattress is more durable than the Casper. Thanks to the resilience of innerspring coils, the Helix is likely to last a year or two longer than the Casper mattress. However, both beds are made with high-quality materials and durable builds that mean they should last longer than the average bed. Expect around six to eight years of use from the Casper and seven to 10 years on the Helix.
The Helix Midnight sleeps cooler than the Casper. Because the Casper is made from 100 percent foam, there isn’t the same level of breathability as there is on the hybrid Helix bed. While both beds sleep cool enough for the average sleeper, we’d recommend that hot sleepers opt for the Helix over the Casper. For other choices, see the best cooling mattresses.
The Helix Midnight is thicker than the average bed and made from layers of foam and innerspring coils. The top layer of the Helix is made from the brand’s proprietary Memory Plus Foam, a medium-firm memory foam that deeply contours to the body.
Next is a thin layer of high-grade polyfoam that absorbs motion from the coils beneath and protects the body from sinking in too far. The support system boasts a thick 8” layer of individually wrapped coils for targeted support.
The Casper Original mattress is an all-foam bed with an average thickness. The top layer of Airscape Foam has a soft feel, yet is still more responsive than memory foam. This top comfort layer is hole-punched to promote breathability and cooler sleep.
The second layer is Casper’s ergonomic Zoned Support, which boasts firmer memory foam along the middle third of the bed and softer foam at the feet and shoulders. The final layer is a high-density foam that further dampens motion transfer and brings some stability to the edges.

Helix Sleep ships mattresses for free to all 50 states in the U.S., and the brand ships to parts of Canada for a fee. Helix manufactures beds to order, so the shipping time is a bit longer than average. Expect to receive your bed in roughly four to 15 business days.
Every new Helix mattress comes with a 100-night sleep trial. In other words, from the date your new bed is dropped off on your doorstep, you have 100 nights to see how you like it. After a 30-day adjustment period, Helix offers full refunds during the trial period.
If you decide to return your new mattress, Helix works with you to arrange a mattress pickup, so you don’t need to stuff it back into its box. For customers who decide to keep their Helix mattress, it comes with a 10-year warranty. The Helix mattress warranty covers defects in materials or workmanship, including things like foam cracks or body indentations greater than 1” deep.
Mattresses ordered from casper.com ship to the contiguous U.S. and parts of Canada for free, with a fee for shipments to Alaska and Hawaii. Because Casper has warehouses located across the U.S. and Canada, you can expect your new mattress to arrive in around two to five business days.
Casper mattresses also come with a 100-night trial period that starts the day that you receive your new bed. However, you’re not required to wait 30 nights before deciding if the Casper is the best mattress for you. According to Casper’s return policy, you may return your bed at any time during the trial period for a full refund. In that case, the brand will send a team to your door to pick up the used bed and take it to a charity or recycling center.
Every Casper mattress comes with an industry-standard 10-year limited warranty. It covers similar defects as the Helix warranty, including body impressions greater than 1” deep and flaws in the foam.
