Highlights

The Helix mattress is a bed that’s made just for you, literally.

With the Helix Color-MATCH system, you’ll be paired with one of nine new mattress models recently launched by Helix. All you have to do is complete the Helix Sleeping Quiz, which asks you to answer questions about your sleeping style, body type and comfort preferences. With this data, Helix will determine which of their mattresses matches your firmness, support and pressure relief needs.

 


Take a closer look at each of the nine mattress models:

Made with Helix Memory Plus Foam

Memory Plus foam is great for side sleepers. It provides balanced support which is just enough to keep your spine aligned without feeling too stiff. Too much support for side sleepers can cause discomfort.

*Helix’s most popular option for the average sleeper.

Made with Helix Dynamic Foam

Helix Dynamic Foam provides extra support, making these mattresses a particularly good choice for back and stomach sleepers. Although, side sleepers are welcome!

Helix Specialty Mattresses*

*Helix specialty mattresses start at $1,190 for queen.

  • Casper is one of the early market leaders in the foam mattress space and offers a good universal mattress for the average sleeper.
  • Casper has crafted a memory foam mattress that is breathable and promotes airflow, so you won’t get that hot, sinking feeling that you would with traditional memory foams.
  • The Casper team is continually refining its design based on customer feedback and sleep tests; so buying a Casper today doesn’t necessarily mean it’s the same one from a couple years ago. Casper’s latest innovation – Zoned Support – is a new foam system that contours high-pressure areas like your hips, shoulders, and core to provide relief and support where it’s needed most.

Layers inside the mattress

Each of the nine new mattress models has the same base construction.

The difference lies in the second layer, or the comfort layer, with the exception of the specialty mattresses. Depending on the model, this layer will be made with either Helix Memory Plus Foam or Helix Dynamic Foam.

Memory Plus foam provides proper support and pressure relief for side sleepers without being too stiff, while Dynamic foam provides extra support and lends itself to being a good option for back and stomach sleepers.

  1. Helix Two-Layer Cover: The Helix Midnight is topped with a dual-layer cover that can be zipped off. The stretchable top layer is soft to the touch, while the lower layer promotes airflow and breathability.
  2. 2’’ Memory Foam Comfort Layer: Directly below the mattress cover is the comfort layer made of Memory Plus Foam – a special foam blend by Helix. This layer is designed to provide pressure relief in areas such as the hips and shoulders making this mattress great fro side sleepers. (Remember this is the layer that differs depending on the model!)
  3. 1’’ High-grade Polyfoam Transition Layer: Next you’ll find the transition layer made of high-grade polyfoam designed to provide ergonomic support and cushion.
  4. 6’’ Pocket-coil Body Shape Layer: This layer is made of 660* individually wrapped pocket-coils to help cradle your body and limit motion transfer. The outer coils reinforce the perimeter of the mattress to provide edge support.
  5. 1’’ DuraDense Foam Base Layer: The bottom layer of the Midnight mattress is made of dense memory foam that provides overall durability and support.
