What's Inside The Helium Sleep?

Made with TLC so you get all the ZZZ's

The Helium Sleep Layers

1. Plush Cover - The smooth, soft cover is made with a stretchy, durable blend of viscose and polyester for a cozy feel.

2. Aerated Latex (non-allergenic) Foam (1.5 inches) - The small holes in this top latex (non-allergenic) layer constantly pull heat away from the body for a cooler sleep. The latex (non-allergenic) also supplies a nice, springy feel that makes bedroom activities other than sleep especially enjoyable. 😉

3. Gel Memory Foam (2 inches) - Our proprietary foam formula features larger cells than traditional memory foam. This layer helps transfer heat away from the body so you stay cool.

4. High-Density Base (7.5 inches) - Our long-lasting, high-density foam core forms the foundation of your Helium Sleep. It’s firm enough for good spinal alignment without creating an uncomfortably hard-feeling mattress.

Frequently Asked Questions

The Helium Sleep is manufactured by seasoned mattress professionals who have been designing and crafting mattresses for decades. We’ve taken everything we’ve learned over our many years of experience to create a supportive, durable mattress that provides optimal comfort for every type of sleeper: back, stomach, side and combo! Plus, its gel memory foam and aerated latex (non-allergenic) foam inner helps transfer heat away from your body as you sleep, keeping you cool all night long.

We take care to select high-quality materials for the Helium Sleep, each with a distinct and important function:

  • Outer cover - made with a blend of quality fabrics, the cover wicks away heat and moisture to keep you cool
  • Top comfort layer - made of the finest aerated latex (non-allergenic), our comfort layer provides ideal softness while absorbing pressure and blocking heat buildup
  • Gel memory foam layer - with pressure-relieving gel beads, you’ll get balanced support that helps alleviate back, neck or joint pain
  • Base foam layer - the Helium Sleep’s long-lasting, high-density foam core is firm enough for good spinal alignment without creating an uncomfortably hard-feeling mattress.

When placed on a strong foundation or base, the Helium Sleep mattress can support an industry-leading 750 pounds. For customers over 300 pounds we strongly recommend purchasing the King Helium Sleep and the companion King Helium Sleep Foundation.

Great News: Your Helium Sleep never needs to be flipped, since the memory foam and latex (non-allergenic) comfort layers are on the top side. To increase the longevity of the mattress, we recommend rotating the mattress 180 degrees or head-to-toe every 3 months.

Once you open your Helium Sleep mattress from the sealed vacuum-compressed 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.

In the colder winter months, your Helium Sleep 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.

Remember, a new mattress is a big change for your body, so it may take a night or two to get used to it. With our 101-night sleep trial, you’ll get more than 3 months to try it out!

The allergy risk is negligible, as the latex (non-allergenic) core is washed thoroughly and the proteins typically responsible for triggering allergic reactions are denatured by the high temperatures we use during manufacturing. According to medical literature, there haven’t been any cases of allergic reaction to latex (non-allergenic) mattresses.

The soft mattress cover will also protect your skin from direct contact.

Yes, financing is quick and easy! With Affirm, you can buy now and pay later with $0 down and 0% APR financing for up to 36 months. No hidden fees, deferred interest or catches: you’ll know exactly what you’ll owe before you commit. You also have the flexibility of picking a payment plan that suits your budget, with plans ranging from 3 to 36 months depending on your order size.
