After a difficult day at work, one of the best feelings is crawling into bed and sprawling out or curling up to take the best nap of your life. Unfortunately, if the mattress is too lumpy or uncomfortable, then you may just forsake the nap and spend hours scrolling online for a new one.
Casper and Helix are two of the biggest names in the online mattress space, and for good reason. Both have built loyal followings, strong reputations, and a range of options to suit different sleepers.
But popular doesn’t always mean perfect for you. So how do they really stack up against each other?
We put both brands head-to-head to help you figure out which one deserves a spot in your bedroom.
Casper: Simple, Streamlined, and Stress-Free
Casper works well for those who want a straightforward option without feeling overwhelmed in the decision process.
When shopping on Casper’s website, the quiz centers its questions around the typical issues of any mattress that’s not working (waking up in a sweat, feeling your partner toss and turn, budget, aches and pains, etc).
At the end of the quiz, they present the mattress that is supposed to achieve what is desired. Again, pretty straightforward and gives you one option based on the answers chosen.
They also have a pop-up that includes saving 5% on hybrid and maxes.
What’s Inside: Casper’s Layer-by-Layer Breakdown
Casper lists about 7 layers in their mattresses.
- QuickCool Cover: Uses specialized yarn to give an instant cooling sensation right where you sleep
- Phase Change Material: Pulls heat away from your body for a refreshing feel as you fall asleep
- Soothe Memory Foam: Contours and conforms to your body for pressure relief
- 6 Heat-Removal Bands: Work through the mattress to continuously push excess heat out
- Firmer Foam: Keeps your waist supported and prevents uncomfortable sinking
- Memory Foam Channels: Cradle and support the natural curve of your body
- Responsive Coils: Boost support and motion isolation, with edge reinforcement giving you more usable sleep surface
Helix: A Helpful Quiz and More Customization
When first clicking on the Helix website, they mention a 60-second quiz to find the perfect mattress.
There is also currently 20% off sitewide. When taking Helix’s quiz, the questions are similar to Casper but are a little more in depth.
The quiz asks about height, weight, age, typical sleep position, feel preference (soft, medium, firm), whether one wakes up with back pain, overheating, and budget.
At the end, they present the best option based on the preferences selected.
What’s Inside: Helix’s Layer-by-Layer Breakdown
Not talking about literal technology in the sense of electronics, but rather what are the layers to a great mattress. Some of the Helix mattresses have up to nine layers. Some of these layers contain:
- Cooling: Built-in temperature control technology with a choice between a Breathe Knit cover or an upgraded GlacioTex Cooling Pillow Top
- Comfort: Multiple foam layers including Memory Plus Foam and Helix Responsive Foam for pressure relief, contouring, and ergonomic support
- Coils: Thousands of individually wrapped steel coils with zoned lumbar support and full perimeter reinforcement, plus a microcoil layer for added durability
- Base: DuraDense foam anchors everything, keeping the mattress supportive and long-lasting
- Heavy-duty option: TitanCore steel coils are available for plus-size sleepers, offering sturdier support and better motion isolation
Breaking Down Each Brand’s Mattresses
Casper offers three mattress categories (foam, hybrid, and max) with about seven options total. It’s a deliberately curated lineup designed to avoid decision fatigue. Their top pick right now is the Dream Hybrid, which earned high marks from Consumer Reports in 2026 thanks to its responsive springs and ergonomic support zones that reduce tossing and turning.
Helix also has three collections (Core, Luxe, and Elite) but goes further by offering soft, medium, and firm variants across all of them. They also have specialty picks that Casper doesn’t:
- Midnight: their top-rated mattress, built for side sleepers with pressure point relief and a medium feel
- Plus: designed specifically for plus-size sleepers
- Dusk Luxe: made with couples in mind
Don’t Forget Frames and Foundations
Casper offers eight frames total, with three adjustable base options – a more adjustable variety than Helix. Their standard frames also allow you to swap out headboards, which is a nice touch for customizing the look of your bedroom.
Helix carries around eight base options, most of which come with a headboard already included. Their standout is the Ludlow frame, engineered to be completely silent and creak-free – a small detail that makes a big difference when you’re getting up in the middle of the night.
How Much Will You Actually Spend?
The two brands are in a similar price range overall, with a few notable differences at either end:
- Casper starts around $599 and goes up to roughly $4,800
- Helix starts around $799 but tops out closer to $4,000
Both offer financing through Affirm, with the possibility of 0% APR for a set number of months.
Casper has the lower entry price point, making it slightly more accessible for budget-conscious shoppers. Helix’s ceiling is a bit lower on the high end. Either way, prices fluctuate with sales, so it’s worth checking both sites before committing.
Test It Before You Commit: Trial and Return Policies
These two brands have strong trial policies:
- Casper has a 100-night trial for their mattresses with free returns.
- Helix has a 120-night home trial.
Helix also mentions that if you’re unsatisfied, then they’ll exchange for a mattress of equal or greater value.
Ratings and Reviews: What Customers Are Actually Saying
Both brands collect plenty of praise around comfort, feel, and the delivery experience. Where they differ is in what customers complain about:
- Casper negative reviews mention delivery issues, an off-putting smell upon unboxing, and the mattress feeling too firm for some sleepers
- Helix negative reviews tend to focus on the mattress losing firmness over time, sinking, or feeling overpriced for what you get
Neither brand is without its critics, but the overwhelming majority of reviews for both lean positive. The biggest takeaway here is that Helix simply has far more customer feedback to draw from, which can make it easier to research specific models before buying.
Which Brand Should You Buy?
Casper and Helix have earned their spots at the top of the online mattress world, and neither is a bad choice. But the right one comes down to what kind of shopper you are.
- If you want to pick a great mattress and move on with your life, Casper is built for you. The streamlined selection, simple quiz, and lower entry price make the whole process refreshingly painless.
- If you want to dig deeper and find something truly dialed in to how you sleep, your body type, and your comfort preferences, Helix delivers on that with more options, more customization, and a longer trial period to back it up.
The prices are comparable, the ratings are similar, and both brands offer financing and solid return policies so you’re never fully locked in.
So really, the only losing move here is doing nothing. If your mattress has seen better days, your body is already telling you it’s time. Whether you go with the simplicity of Casper or the precision of Helix, you’re trading restless nights for something better.
