Helix Mattress 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.

Purple mattress

Purple Mattress Highlights

  • The Purple is a mattress with a big personality, but it does have a lot to boast about: it sleeps cool, is great for spinal alignment and does a good job with reducing any movement you’ll feel from other people (or animals).
  • Customers who own the Purple have claimed it’s helped them relieve back and neck pains.
  • The Purple is topped with a unique pressure-releasing material that is especially great for back and side sleepers – when you lie on your back, it will help your spine maintain its natural curve and when you lie on your side, it will help keep your spine straight.

Compare the Inside Layers

A look inside the Helix Midnight

Inside the Helix

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.

Here is a look inside the Helix Midnight, the most popular of the new models.
  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.

Inside the Purple mattress

Inside the Purple Mattress

The Purple mattress is made with a layer of hyper-elastic polymer (designed to provide great pressure relief) on top of two layers of high-density polyurethane foam (designed for durability, support and motion isolation). Here’s a look at the layers, described from top to bottom:

  • Responsive Knit Cover: Soft and stretchy cover that helps maximize the flexing properties of the Smart Comfort Grid™. The breathable design also promotes airflow to help you sleep cool.
  • Smart Comfort Grid™: Designed to cushion your shoulders and hips (pressure points), and support your body’s natural shape.
  • Plush Comfort Foam: Soft, high-density polyurethane foam designed to enhance the responsiveness and feel of the Smart Comfort Grid™.
  • Support Foam: Medium-firm, high-density polyurethane foam provides structural support to the mattress.

These two hybrid mattresses bring a lot to the table (or bed), but which is best when it comes down to the Helix vs. Purple mattress? Well, it’s not such a black-and-white answer.

Helix offers a customizable shopping experience that’s tough to beat. With the Color-MATCH system, Helix can connect you to a bed made just for your needs. But Purple’s thoughtful design targets sleepers large needs in a bed – pressure relieving properties and spinal alignment – in a big way. In fact, the Purple almost scored a perfect 10 in our testing for spine alignment!

Both of these mattresses are sure to satisfy you. If you’re more particular about your mattress needs, Helix will be the way to go since you can customize your selection based on specific preferences, but if you’re looking for an overall great mattress the Purple will be a great choice as well.
