You should buy Casper if: If you’re an average sleeper looking for a bed that hugs you, the Casper would make a great pick. The Casper mattress does a nice job of appealing to many types of sleepers – it’s not too firm or soft, it will keep you cool, and it uses zoned support to keep you comfortable and avoid pain at the pressure points like your hips and shoulders.

You should buy Helix if: If you want a more customized mattress, Helix offers more specialized mattress models. If you have a particular need or preference, the Helix may be a better option for you. For instance, the Helix offers great motion isolation, meaning you won’t feel your partner moving around as much on the other side of the bed. That make the Helix great for couples and combination sleepers who move around a lot during the night. The Helix can also appeal to heavier people (200+ lbs) and is a better option than the Casper for people who tend to sleep hot.

Compare the Construction of the Mattresses

The main distinguishing feature between the Casper and Helix mattress lies in their differing constructions. The Casper mattress is entirely made of foam while the Helix is made of a combination of foam and coils. Hybrid mattresses like the Helix feel more bouncy than an all-foam like the Casper. Hybrid mattresses also will be more firm feeling and durable over time.

If you’re a heavier sleeper, you’ll be more supported on a hybrid like the Helix. Average sleepers will be comfortable on either the Casper or Helix. Other special needs like sleeping hot can be solved the Helix. The hybrid construction allows for more airflow through the bed so you won’t trap in body heat.

Now, we’lI take a deeper look inside each mattress to see what sets them apart.

Inside Casper Original

Inside the Casper Mattress

The Casper is composed of four foam blend layers designed to increase breathability, relieve pressure points, provide contouring, and offer a great support system. On the top layer of the Casper, you’ll find open-cell foam specially designed to avoid the heat trapping that memory foam is infamous for. The zoned support layer under this one is designed to evenly distribute your body weight across the surface. This is great because then your hips or shoulder won’t sink in too far and you won’t wake up in pain! Finally, the bottom layer of the Casper ensures its long-term durability so this mattress will last you for years to come.

  • Open-cell foam top layer designed for breathability and increased airflow
  • Zoned support foam layer – targeted support and spinal alignment
  • Durable support foam layer – added support and to prevent sinkage
Inside Helix

Inside the Helix Mattress

Each Helix mattress has the same construction with a unique comfort layer for added support. The dynamic layers of foam add cushioning and softness. The cover on the Helix is super soft to the touch and has a breathable construction for a cool night’s sleep. Inside the Helix mattress, the memory foam and polyfoam layers provide a cushiony layer of top support that allows your body to sink in just enough for proper alignment and comfort. Like the Casper, your body weight is evenly distributed across the surface for a pain-free night’s sleep. Finally, at the base of the Helix mattress lies a coil layer that makes the Helix great at isolating motion and a dense foam layer for long-term durability. 

  • Soft-touch cover – increases airflow
  • Memory foam comfort layer – avoid pain in pressure points (hips and shoulders)
  • Polyfoam transition third layer – offers support and cushion
  • Body shape layer – coil layer for motion isolation and edge support
  • Foam base layer – dense layer of durability

Verdict: Is Helix or Casper Better?

After comparing the Helix vs. Casper mattresses, the Casper barely beats out the Helix with a score of 9.1/10 compared to Helix’s 8.9/10. However, Helix is a hybrid mattress and offers different features than the memory foam Casper bed so it may better suit your needs. Both mattresses are pretty comparable in pricing so your choice will most likely be decided by the varying features.

When making the choice of the best mattress for you, take into consideration Helix’s customizable design that allows you to combine several attractive mattress qualities in one bed. This makes the Helix better for couples while the Casper is a great choice regardless of sleeping position and sleepers of all body types thanks to its medium-firmness level. Both mattresses ensure a 10-year warranty as well as a 100 night sleep trial

If you love memory foam beds, the Casper may be for you, but if you are looking for a little bit of everything then the Helix may be your go-to. No matter which brand you choose, you’ll be sure to sleep comfortably on your new bed for many nights to come.
