Frequently Asked Questions

What are the benefits of the Midnight mattress?

The Helix Midnight is scientifically designed to give side sleepers who love a medium-feel mattress an excellent night of sleep.

It cushions shoulders and hips to reduce pressure & pain when you wake up, and includes exclusive SupremeSupport 2.5 Memory Foam, with 2.5x more cushioning than other mattresses, to help you relax and recharge.

Why is the Midnight the best mattress for side-sleepers and sleepers who toss and turn?

The Midnight mattress is designed with exclusive, ultra-dense memory foam layers that cradle the hips and shoulders, which often experience pressure when we sleep on our sides or we toss and turn. It is cozy and supportive, ensuring your body stays in alignment while you sleep.

How does the GlacioTex Cooling Cover work?

The GlacioTex Cooling Cover is a great option for people who like that feeling of crisp, cool sheets when they get into bed each night. Made from Helix's cutting-edge, heat conductive fabric, the GlacioTex Cooling Cover draws heat away from the surface of the mattress for a cool-to-the-touch feel — while also feeling soft and comfortable beneath you.

What's the difference between the Midnight and Midnight Luxe?

The Midnight mattress is great if you’re looking for a superior mattress at a great price, including deluxe foams for comfort and cooling options. But the Midnight Luxe offers the high quality of the Core mattress, PLUS enhanced lumbar support and more advanced cooling & support options.

Does this mattress require a box spring, foundation, or a particular base?

A support system for your mattress is required. It is recommended to use the Helix Foundation to provide correct support and avoid sagging over time. If you prefer to use something different, it is recommended to use a bunkie board with a box spring, or any support system with a firm, flat surface and thick slats no wider than 5.5 inches apart, which can cause sagging and void your warranty.

Does the Midnight mattress have any safety certifications?

The Midnight mattress, like every Helix mattress, is assembled in their Arizona facility, allowing Helix to ensure the highest quality every single time. Helix mattresses are GREENGUARD Gold Certified and made with CertiPUR-US certified foams, which guarantees they are made without any harmful chemicals including ozone depleters, PBDE flame retardants, mercury, lead, heavy metals, formaldehyde, and have extremely low impact on indoor air quality.

Reviews

Wish I Had Bought It Sooner!

"I love the Helix Midnight mattress! With my old mattress, I woke several times a night and woke up with pain and soreness in my joints. Once I started sleeping on my Helix, my sleep drastically improved. I sleep more deeply with less frequent wakings and I don’t wake up in pain. The mattress molds to my body, offering support where needed. It is so comfortable! I wish I had bought it sooner."

Tracy L. (5/5)

The quality of the mattress

"The quality of the mattress is decent. It's just not as comfortable as I was hoping it would be after taking the quiz and having this recommended to me. I was finally able to improve my overall sleep by stacking my originally purchased Helix mattress on top of it like a mattress topper."

Jeannie A. (4/5)

Would have loved it, but someone stole it after delivery :(

"I was so excited for this mattress. After reviewing dozens of mattresses, I went with the Helix. It was delivered to my parents’ home as I was in the process of moving. To my delight, it was delivered the night before I closed on my new home. It, along with other items, were loaded onto the trailer to be delivered to my new house the following day. Sadly, someone went into the trailer and stole it and I never got to try it."

SALLYE M. (5/5)

I wish the cooling top actually worked.

"The firmness and height are great. This mattress is springy and comfortable. The problem is have is I got the cooling top, since I am such a hot sleeper, and it hasn't made any difference. I am disappointed really in that since it was an upcharge."

Ashtan R. (3/5)

Best sleep in years

"I’m incredibly impressed with my Helix Midnight king size mattress. It’s so comfortable and I haven’t slept this well in years (even my Oura ring noted a great improvement in sleep quality). I find this to be the perfect medium. Not too firm; not too soft; just right! I’m very happy with this purchase and highly recommend it."

Kevin S. (5/5)

Get it

"Best sleep, every night. Comfort, cool and I paired it with an cool mattress pad, so I don't sweat anymore at night. I did my homework and concluded on the Midnight. It has been 3 months and I haven't slept on my sofa since because I really love the comfort and quality of my sleep. Thank you."

Kevin A. (5/5)

Best decision ever!

"Love this mattress and cannot believe how much this one decision could impact my overall health. This Helix mattress perfectly conforms to my body and supports my side-sleep position. I no longer wake with terrible hip pain. And the white-glove delivery and assembly couldn't have been easier. I now look forward to restful nights on my beautiful mattress."

Alexis C. (5/5)

Great mattress

"This mattress is amazing I had no idea what stiffness i wanted but I knew I wanted a little cushion and my boyfriend prefers firmer I went with a 6 and its a perfect compromise we both sleep so much better and our dogs put themselves to sleep early just to lay in bed."

Kadi h. (5/5)

Excellent mattress for the price

"This mattress is great if you prefer it on a slightly softer side. However, after sleeping on it for 4 weeks, it was a little too soft for me and my wife. We decided to exchange it for the twilight."

WORASITH K. (4/5)

No relief for short queens

"Purchased the short queen and it would have been helpful if there was a short option for the base. Currently the mattress and base do not line up. The mattress is incredibly comfortable but the setup is easily the squeakiest I've ever slept on"
