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

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)

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"

Vincent B. (4/5)

Best Sleep and Amazing Support

"We absolutely love our Helix Midnight Luxe mattresses. They are incredibly comfortable, supportive, and have made such a difference in our sleep quality. The balance of softness and support feels perfect. On top of that, Helix customer service has been wonderful to work with. They were helpful, responsive, and truly went above and beyond to make sure we were taken care of. It’s refreshing to find a company that stands behind their products and genuinely cares about their customers. Highly recommend both the mattress and the company!"

Renea Q. (5/5)

Way too soft and loses structure quickly

"I bought a Helix Midnight Mattress about a year ago and it’s already lost its structure. The edge support is basically gone — sides and corners sag, and sitting on the edge makes it collapse. This doesn’t feel like normal wear, more like a build/material issue. Also, this is marketed as a “medium” mattress, but it’s nowhere close. It feels extremely soft — to the point where you sink in way more than expected. The firmness description feels pretty misleading. The warranty process has been worse. I submitted photos showing the problem, including corners/edges with no sheets or anything on the bed. They asked for more photos (frame, slats, tags, full surface) — I sent all of that. Then they kept asking for more photos. It just goes in circles and never actually moves forward. At this point I’ve sent everything they’ve asked for, and the claim is still stuck. Wouldn’t buy from Helix Sleep again."

Elizabeth Q. (1/5)

Highly recommend

"Very pleased with this purchase. I didn't realize how poorly I slept until remedied by this mattress! If I awaken for whatever reason I have no difficulty getting back to sleep. But side dilemma-I very often tell myself "I'll just relax here for ten more minutes" and then, surprise!, it's two hours later. . . I consider this a happy problem and what alarm clocks were made for. Very cozy mattress. PS I'm primarily a side sleeper."

Ellen J. (5/5)

Great support

"Swap in of Helix took only a few minutes. It provides much better support than my old memory foam mattress. No more feeling like you're coming out of a hole. My back pain is greatly reduced. I just finished 12 weeks of spinal decompression. That probably reduced the pain. Hopefully the supportive mattress will keep it away."

Dennis P. (5/5)

An Upgrade

"I had a high quality mattress that wasn't too old, but, it was firm. With some recent health issues, I was having trouble sleeping. I tried the Helix Midnight and I'm sleeping better in all positions. It's just the right amount of 'plush' and 'firm' at the same time. Note; This mattress and others like it are very heavy and require 2 people to handle. Also, I have an old mattress to dispose of."

Robert C. (4/5)

Knocked Me Out Cold

"Day it arrived I unpacked the mattress, laid down to see if it was right for me, and fell asleep with every light on, computer still running, work clothes still on, 2 hours early, before I even put sheets on, and promptly fell asleep like I got beat over the head with a bottle of sleep aids. So I'd say it worked about right for me. Would recommend."
