What are the differences between The HeliumSleep, HeliumSleep Flex, HeliumSleep Luxe, and HeliumSleep 3D Matrix®?
All of our mattresses are backed with our 20-25 year warranty and feature the best in sleep technology so you wake up rested, refreshed, and ready to take on the day! Selecting the right HeliumSleep mattress will come down to the level of support and coolness you prefer.
The original 11” HeliumSleep is our most affordable mattress, built using research and feedback from tens of thousands of past customers. This mattress features a unique, aerated top layer of latex (non-allergenic) for better bounce and breathability, 2” pressure-relieving cool gel memory foam and a high-density, durable support core. Offering a blend of support and comfort with a medium-firm feel, this mattress works well for all sleeping styles, including side, back and stomach sleepers.
Tired of waking up hot? You’ll stay cool and comfy all night long on our 13” HeliumSleep Luxe, the Coolest Bed in the World™. It’s the only mattress with core & surface cooling technology, plus a full seven layers of comfort—including cooling gel memory foam, our patent-pending Ghost Ice Layer designed to sense heat and adjust throughout the night, and a plush cover infused with cooling fibers. With its medium-plush feel, this Luxe is best for side sleepers and back sleepers who love the feeling of snoozing on a cloud. Similar to the other HeliumSleeps, it’s also great for couples because of its low motion transfer.
Next up is the 13” HeliumSleep Flex, our best-selling hybrid mattress that combines the sturdy support of reinforced coils with the plush comfort of memory foam. If you’re used to sleeping on a traditional innerspring mattress, this is the perfect transition to the cooling comfort of gel memory foam! This medium-support mattress also features cooling fiber woven into its plush, quilted cover, for a cool-to-the-touch feel. The Flex is an excellent option for all types of sleepers, as well as couples that are looking for minimal motion transfer.
Finally, the new 12” HeliumSleep 3D Matrix® hybrid is our most luxurious mattress, featuring seven layers of exclusive patented technology for your best sleep ever. Craving a cooler sleep? The 3D Matrix layer features a thermal-conductive gel polymer that absorbs excess heat and transfers it away from your body. Need added support due to joint pain? 1” of soft transition foam cradles your body for amazing comfort, and the Ghost Bounce layer is responsive like latex (non-allergenic) and contouring like memory foam—some say it’s as close as you can come to floating without leaving the ground!

What is a hybrid mattress?
The Helium Sleep Flex and HeliumSleep 3D Matrix® are both hybrid mattresses, which combine the sturdy support of reinforced, individually wrapped coils with the plush comfort of gel memory foam.
Do I still need a box spring/foundation?
All of our mattresses are made to industry-standard sizes, so they’ll fit with your current frame or foundation. However, we highly recommend our matching foundation/box spring for the best support. With its 9-inch height, this foundation ensures that your mattress lays flat and your investment stays in great condition.
Do all Helium Sleep come with a warranty?
Yes! Your HeliumSleep comes with an industry leading 20-25 Year Warranty with proof of purchase from the official HeliumSleep website or an authorized retailer.
Do Helium Sleep mattresses have a break-in period?
Once you open your HeliumSleep mattress from the sealed vac-pac packaging, it may take a few hours to a full day for it to fully expand, breathe and adjust to your room’s temperature. You can sleep on it almost immediately. Remember, a new mattress is a big change for your body, so it may take a night or two to get used to it.
In the colder winter months, your HeliumSleep may take up to 5-days to fully decompress. If it sat on a cold truck or in a cold warehouse, the temperature-sensitive materials will need plenty of time to take their natural form.
If the mattress is returned within the 101 Night Sleep Trial, do I get a full refund?
Yes! As long as you request a return within HeliumSleep’s 101-Night Sleep Trial period you will get a full refund on your mattress purchase!
Do I need to rebox the mattress if I return it?
Nope! Simply contact our friendly customer service team within the 101-Night Sleep Trial period and we’ll coordinate a free pick-up. After we take the mattress off your hands, we donate it to a charity near you, such as Goodwill or Salvation Army.
