Pros and Cons of the Helix Midnight Mattress

The Helix Midnight is for you if: The Helix Midnight isn't for you if:

You want to sleep cool: If you ever find yourself waking up in a sweat, the Helix Midnight may be a good remedy. This is a breathable mattress that’s designed to sleep cool.

You sleep on your back or stomach: Back sleepers and stomach sleepers will want to take into account other products in the Helix line.

You are a side sleeper: The Helix design team has custom-engineered the Midnight model to accommodate people who sleep on their sides.

You don't want to wait for it to adjust: One of the most common complaints about Helix mattresses is that they take some time to fully “break in”... sometimes, up to 30 days.

Helix Midnight Mattress Materials

When considering any new mattress, it’s wise to think about the materials used to construct it. The Helix Midnight is made of premium materials that unite the best aspects of memory foam and individually wrapped coils. Again, it’s all done with side sleepers and combination sleepers in mind. Here’s a closer look at what you’ll find within the Helix Midnight bed.

What’s Inside?

Midnight mattress

  1. Helix Soft Touch Design Mattress Cover: The mattress cover is optimized to promote airflow and to be gentle to the touch.
  2. Memory Plus Foam: A comfort layer, made of Memory Plus Foam, provides medium firmness and optimal pressure point relief.
  3. High-Grade Polyfoam Transition Layer: Transitional polyfoam provides a contouring effect and ergonomic design.
  4. Body Shape Layer: Individually wrapped pocket coils provide motion isolation and edge support.
  5. Base Layer: The bottom layer of the mattress provides sturdiness, structure, and support.

Helix Midnight Mattress Features

There are several attributes that help the Helix Midnight stand out from the crowd. Here are a few highlights.

Support for Side Sleepers

The top and middle layers of each Helix mattress are designed to offer optimum support for a specific sleep type. The Helix Midnight is made to be one of the best mattresses for side sleepers. It also works well for combination sleepers; that is, those who tend to toss, turn, or change positions during the night.

Pressure Point Relief

A special layer of memory foam helps to evenly distribute the weight of the body, cradling you to sleep and keeping your pressure points from any undue stress. This pressure relief helps minimize creakiness, stiffness, and body aches.

Temperature Regulation

Do you tend to run hot? The Helix Midnight is routinely cited as one of the best cooling mattresses. Both the breathable cover and hybrid mattress design promote air circulation and help keep body heat in check.

Compatible Foundations

Any time you’re picking out a new bed, it’s crucial to seek a compatible foundation. The Helix Foundation, sold separately, is the best option if you’re seeking to get the most out of your new mattress. However, Helix says you can also work with your existing bed frame type, specifically if you have a slatted platform, box spring, bunkie board, or slatted foundation.

Sleeping Positions Best for Helix Midnight

The Helix line is all about customization. When you take your sleep quiz, you’ll be recommended a mattress that perfectly matches your unique preferences, preferred firmness level, and ergonomic needs.

Chances are, if you find yourself looking at the Helix Midnight, it’s because you’re a side sleeper. That’s because the memory foam comfort layers in this mattress are uniquely designed to cradle and adapt to side sleepers, as well as those who change sleep position during the night.

If you’re a back sleeper or stomach sleeper, there are other Helix products that may be better-suited to your needs, such as the Helix Dusk and Dawn models.

Helix Midnight Mattress FAQ

  1. Should I flip my Helix Midnight mattress?

    No; in fact, its foam layers are arranged with a clear top and bottom and are not meant to be used upside down. You can rotate your mattress every six to eight months, but flipping is not recommended.

  2. Can I clean my Helix Midnight mattress?

    The standard version of the Helix Midnight has a cover you can unzip and wash. The Luxe version does not offer this removable cover and can only be spot cleaned.

  3. How does the sleep trial work?

    When your Helix bed arrives, you’ll have 100 nights to try it out and make sure it’s to your liking. During the 100-night sleep trial, you can return your mattress at any time for a full refund. You do not need to put your mattress back in the box, and there is no return fee.


The Helix line takes pride in customization. It offers different mattresses for different kinds of sleepers. Side sleepers may love the Helix Midnight. Others may be better off with the Helix Moonlight, the Nightfall, or even a medium-firm mattress from another company.

As far as the Helix Midnight goes, however, there’s certainly a lot to recommend it. It scores well for motion transfer, edge support, durability, cooling, and more. Combination sleepers should find it highly comfortable. As long as both parties favor side sleeping, this is also one of the best mattresses for couples. And, thanks to the breathability of the materials, we can also recommend the Helix to sleepers who run hot.

As for choosing the base version versus the Helix Luxe, that largely depends on your budget. The Luxe is a little more high-end and plusher, but if you’re looking for value, the base version is nothing to sneeze at.
