Helix and Casper are two of the most popular online mattress brands. They both have multiple mattress models and thousands of 5-star ratings, but how do they compare? In this post, we will explore the relative advantages and disadvantages of the flagship mattresses from Helix and Casper.

Helix vs. Casper Mattress Overview

Both Helix and Casper originated between 2014 and 2015, and they have since become major players in the bed-in-a-box business. They have a lot in common, but we’ll focus on the differences so you can move closer to making an educated purchase decision. We’ll also look at how both companies have moved into the hybrid mattress realm and offer several models from which to choose.

Casper vs. Helix Mattress Video Comparison

Of course, there is more to consider than what we could fit into one video or a few bullet points, which is why we’ve assembled the rest of this review.

If you created a list of the 10 most popular bed-in-a-box companies, both Helix and Casper would be on it, alongside GhostBed, Purple and others. As such, if you’re looking to make your decision purely based on reputation, that’s not really going to help much with these two beds. In reality, the Helix mattress vs. Casper debate comes down to five major items:

  • Coils — All Helix mattresses have coils, which tend to, among other things, make a bed more durable over the long run. Casper is now also selling two hybrid models that have coils.
  • Universally Comfortable — Casper is one of those mattresses that almost everyone regards as being dangerously comfortable. Helix is comfortable, as well, but if you forced us to crown a winner, we’d give the slight edge to Casper.
  • More Options — The entire value proposition from Helix is about matching you with the right mattress. They simply have more mattress models than Casper, and Helix does a great job of lining you up with the best option for you.
  • Motion Isolation — Casper wins here, barely, but both beds do a good job at limiting motion transfer within the mattress.
  • Heavy Sleepers — If you’re 250 lb or more, Helix Plus is made just for you.

Helix Sleep Quiz

Just a few steps help narrow down your mattress search

Helix Sleep has taken the approach that not everyone is the same, and therefore no single best mattress exists — hard to argue with that. As such, Helix actually makes more than 10 different mattress models, each designed for different types of sleepers.

Don’t worry; you don’t need to do any of the calculations yourself, nor do you really need to know the difference between all the models. Helix actually runs you through its Sleep Quiz in order to direct you to the most suitable mattress. The Sleep Quiz takes only a few seconds, but it’s a brilliant way to tailor the mattress-buying experience (and cut down on the number of returns).

The Sleep Quiz that you see above is a big differentiator for Helix and is one of the main reasons that someone would get one of their beds. You can take the Sleep Quiz for yourself on Helix’s website.

Design & Construction

Helix uses pocketed coils as the support system in all of its mattresses, whereas the original Casper mattress, Casper Wave, and Casper Element all are entirely made of foam. Casper’s signature construction includes three layers: support foam, memory foam, and an open-cell foam designed to encourage airflow.  Casper now also sells two different hybrid models.

Construction side view of the Helix mattress

There are two things to consider here. The first is a personal preference. You might prefer (or not prefer) the feel of a bouncy, responsive coil mattress.

The second is support. While Casper is undoubtedly a durable mattress, it’s widely accepted that hybrid/spring mattresses are more durable than all-foam beds long-term. As such, we do really appreciate that Casper started selling those hybrid beds also.

Feel & Firmness 

Helix makes a mattress for nearly every sleeper. You can find ones ranging from soft to firm and everything in between. Each Helix mattress also has a supportive, responsive feel to it, partly thanks to the pocketed coil layer found in their foundations.

If you forced us to make a split-second decision, we would anoint Casper, the winner on comfort. In fact, we think Casper is one of the most comfortable mattresses available online today.

Casper is near universally loved

Now, clearly, comfort is subjective, but our entire team agrees that Casper is comfy—and we are all different weights, heights, genders, and have different sleeping preferences. Casper is just a universally comfortable bed.

Casper has a more neutral feel to it. Picture a soft, comfy foam and that’s how Casper feels. It doesn’t feel like memory foam or latex foam or an innerspring bed. It just feels neutral, almost boring (in a good way). It’s about a medium on the soft-to-firm scale.

While you can get Helix in a variety of firmness levels ranging from soft to firm, Casper is middle of the road. It’s about a medium on the soft-to-firm scale.

Here’s what it all boils down to. If you’re under 250 pounds and just want the easy, safe pick, that’s Casper.

Other Factors To Consider

Construction and feel aren’t the only things that matter in a mattress. Here are a few other important areas of comparison for Helix vs. Casper.

Edge Support 

We can’t really pick a clear winner here. In fact, neither Helix nor Casper is fantastic for edge support. But this is something that we see with a lot of softer mattresses: They just compress a little too much along the edges so that you get a little of that roll-off sensation. 

There’s an easy solution for this, however, and that is to upgrade sizes. Edge support only really affects couples, so instead of getting a queen or a full, if you can, upgrade to a king that gives you more room to stretch out.

Motion Isolation

We are splitting hairs on this one, but if you are a sensitive sleeper that wakes easily, Casper is probably the better option. Helix is actually efficient at deadening cross-mattress motion, as well, but it’s hard to beat out an entire foam bed. In general, coil mattresses tend to reverberate motion more than their all-foam brethren.


If you tend to get hot when you sleep, Helix is definitely the better choice. The coils in the mattresses’ base allow for more airflow than an all-foam foundation and simply lends itself to better temperature regulation

Given that most of Casper’s mattresses are entirely made of foam, they won’t cool you down as easily. Even with the top layer that’s designed to encourage airflow, we would consider all of Helix’s mattresses temperature neutral.

Body Type Analysis

Both mattresses can accommodate different body types, but Helix covers far more range than Casper does in this department.


Casper does quite well for smaller body types. Petite sleepers will have fewer issues with edge support or foam durability. Sleepers under 150 pounds can opt for Helix, but you don’t necessarily need the extra support it provides. 


With Helix compared to Casper for an average body type, it’s a fairly close call. Casper mattresses still hold up well in this category — especially its hybrid models. In general, though, Helix offers more options for sleepers in this weight category because they offer a bit more support if you need it. 


It’s no contest for heavy sleepers: Helix is the clear winner with its underlying coil support system. The Helix Plus is even designed specifically for sleepers who weigh 250 pounds or more. That being said, the Casper Wave Hybrid will also now be a good solution for heavier people. It’s a 13-inch coil bed with a zoned support design. 

Sleeper Type Analysis

In the Helix vs. Casper mattress debate, both companies can accommodate different sleep styles fairly well.

Side Sleepers

Helix has more options for side sleepers, like the Moonlight and Sunlight models, which have a plush, pressure-relieving profile. Casper can accommodate side sleepers, too, but more petite side sleepers may find its mattresses a tad too firm.

Combo Sleepers

Both Helix and Casper are great for combo sleepers who favor all positions. Each has medium firmness levels that are really accommodating, and their responsive feels make it easier for combination sleepers to switch positions. It ultimately depends on the money you want to spend and what your body type is. 

Back & Stomach Sleepers

Both Casper and Helix provide enough support for back and stomach sleepers; it just depends on how firm you want to go. Casper will be fine for petite to average back and stomach sleepers. However, if you weigh over 230 pounds or want a particularly firm mattress, Helix is the way to go.

Casper vs. Helix Review Verdict

The Helix mattress offers a ton of different options and are almost “customized” based on what the specific sleeper needs. If you like the idea of being matched up with a mattress via sleep quiz, and you’re in the market for a hybrid mattress, you might really enjoy Helix. The company has an option for everyone and can support all body types. 

Casper, on the other hand, is perfect for people who are looking for a reliable, basic, all-foam mattress with a classic foam feel that most people seem to love. Its new hybrid models make it even more competitive against brands like Helix. There’s a reason why Casper is arguably the most popular online mattress in the game right now.

Casper and Helix Company Policies

Let’s cover an area where most consumers have questions: company policies. Both Helix and Casper offer free shipping with their mattresses.

The beds show up compressed and plastic-wrapped inside of a box that’s about 48 inches tall. It’s actually a pretty neat thing to see a full size bed that has been (somehow) fit into a box. All you need to do is cart the box inside, remove the plastic wrapping, and allow your bed to fully inflate.

Both brands also offer a 100-night risk-free trial where you can evaluate the bed from the comfort of your own home. You have more than three months to make your mind up on the mattress. This should be plenty of time to allow your body to adjust to the bed.

If for whatever reason, you’d like to return the mattress, both Helix and Casper offer 100% free returns. In fact, they will send someone to your house (usually a charity or 1-800-GOT-JUNK) to pick up the mattress free of charge.

You read that right — completely free returns, even if you’ve slept on the bed for 99 nights. That’s a pretty great policy. Most other mattresses that we’ve reviewed also have the same policy.

If everything works out and you decide to keep the mattress, they both come with a 10-year warranty. Again, this is standard for the online mattress shopping industry. Leesa and Tuft & Needle, along with plenty of other brands, also have the same warranty policy.
