Construction

Helix Midnight and Midnight Luxe Mattresses are designed with comfort and support in mind. At 12 inches high, Midnight is constructed in 4 layers. Midnight Luxe is 14 inches high and has 6 layers. The following sections describe the construction in detail.

Comfort

Midnight’s Soft Touch cover is made from a breathable knit fabric that promotes air flow and feels soft to the touch. Midnight Luxe has a quilted pillow top with your choice of a breathable TENCEL cover or cool-to-the-touch GlacioTex cover. The top layers of both mattresses are made of Memory Plus foam to provide comfort and relieve pressure on your spine, neck, shoulders and hips.

Support

Both mattresses have a coil core that supports and contours to the shape of your body. The individually wrapped coils are reinforced at the perimeter to provide edge support and prevent sagging. Midnight’s core contains hundreds of coils with edge support on two sides. Midnight Luxe has thousands of coils that provide targeted support for your body and edge support on all 4 sides.

In both models, a high-grade PolyFoam transition layer sits on top of the coil core, while high-density DuraFoam forms the bottom layer. The transition layer enhances support and cushioning and the base layer provides durability and support. Midnight Luxe has an extra Gel Visco layer for support and cushioning.

Firmness

A medium feel makes both mattresses comfortable without being too soft or too firm. On a firmness scale of 1 to 10, Midnight and Midnight Luxe have a 5-to-6 rating. Ideal for side sleepers, a medium mattress is a good choice for couples with different sleep preferences.

Mattress In a Box

Helix ships the Midnight and Midnight Luxe mattresses in a box directly to your home. Shipping is free in the United States. Before shipping, the mattress is compressed, rolled and wrapped in plastic to fit in a 47-inch x 16-inch x 16-inch box.

When your mattress arrives, it’s a good idea to take it out of the box right away so that it can decompress for 30 to 45 minutes. The company states that you should not leave the mattress in the plastic wrap longer than two weeks.

100-Night Sleep Trial

Helix understands that it can take weeks or months to know if a new mattress will work for you. At first, your Midnight or Midnight Luxe mattress may seem too firm if your body is used to sleeping in an old, sagging mattress.

The company’s 100-night sleep trial lets you adjust to the new mattress before making a final decision. After a 30-day break-in period, you can return the mattress until 100 days after the delivery date. Just contact a Helix Sleep Specialist to arrange a mattress pickup and refund.

Midnight and Midnight Luxe Mattresses: Pros and Any Limitations

After researching the Helix Midnight and Midnight Luxe mattresses, we believe that both models offer the following benefits and minor limitations.

Balance of Comfort and Support

The Midnight and Midnight Luxe mattresses are both designed to provide a balance of comfort and support. Thanks to the layers of Memory Plus foam and multiple layers of high-density foam, you’ll enjoy support for your spine and pressure relief at your shoulders, neck and hips. These features combine to help prevent back and joint pain so you can wake up without feeling stiff and sore.

You’ll love the Midnight Luxe quilted mattress topper. It adds a luxurious layer of comfort to your sleep experience.

Your lower back will appreciate the zoned support from the Midnight Luxe coil core. In both models, reinforced coils provide edge support and durability. You won’t feel like you’re falling off the mattress when you get out of bed.

Sleep Comfortably Cool

When shopping for the best mattress in a box, temperature control is an important factor. No one wants to sleep feeling hot and sweaty. Both mattresses help you sleep in cool comfort. The Midnight model has a soft knitted cover that promotes airflow. Midnight Plus upgrades the cooling technology with two mattress cover options: the moisture-wicking, breathable TENCEL cover or the cooling GlacioTex cover.

Free Shipping in a Box

Let’s face it, getting your mattress home from a store can be a hassle. You have to either take the mattress home yourself or arrange an appointment with a delivery and setup team.

When you order the Midnight or Midnight Luxe mattress, you get free shipping to your home in the United States. The mattress arrives in a box, so all you have to do is bring it inside and take it to your bedroom. To be on the safe side, you may want to use a dolly or ask someone help you carry it inside.

Decompression Wait Time

A minor inconvenience is that you won’t be able to use the mattress or set your favorite quilt on the bed right away. After being compressed and rolled up in a box, your Midnight or Midnight Luxe mattress will need 30 to 45 minutes to decompress. A mattress that’s been in a box can also have an odor, so make sure the room is well-ventilated to let it air out.

Risk-Free 100-Night Sleep Trial

Whether you choose the Helix Midnight or upgrade to the Midnight Luxe, you’ll need time to adjust to your new mattress. Just knowing that you have 100 nights to try it out can make it easier to choose a mattress. Even the best mattress in a bag needs a period of adjustment.

Your body may be used to sleeping on an old, soft mattress. For that reason, Helix requires that you keep the mattress for a 30-day break-in period. It may be just the length of time you need to know for sure if your new mattress is right for you. If it’s not working for you after 30 nights, you can return it within 100 days after delivery. Helix will even pick up the mattress for you. It’s nice to know that you have the time you need to decide if you can sleep comfortably on your mattress.

Flexible Payment Options

If you’d rather not pay the entire price upfront, you can pay for your Midnight or Midnight Luxe mattress in installments. Flexible financing options are available, even if you have no credit or a low credit score. Some payment plans are even interest free. It’s helpful to know that flexible financing is available when you’re shopping for the best mattress in a box for your home.

Helix Midnight and Midnight Luxe Mattresses: Final Thoughts

With the Midnight and Midnight Luxe, Helix offers hybrid mattresses with ample support and comfort. Both models have a memory foam layer as well as multiple layers of high-density foam for contouring and support. Midnight has a breathable cover to help keep you cool. The Midnight Luxe offers upgrades such as a quilted pillow top and your choice of a cooling mattress cover.

Both mattresses have a coil core that provides contouring and support. Reinforced coils add edge support on 2 sides of the Midnight mattress and all 4 sides of Midnight Luxe. The Midnight Luxe core also provides zoned support where you need it most.

Helix provides delivery in a box and a 100-night sleep trial. The company backs its mattresses with a Limited Lifetime Warranty. Flexible payment plans are available. These services help make buying a mattress more convenient and less stressful.

If you’re searching for the best bed in a box mattress, reviews can help you make an informed decision. After our research, we believe that the Helix Midnight and Midnight Luxe mattresses are quality products of value.
