Helix versus Leesa

If you find yourself sniffling and sneezing each time the seasons change and you fire up the furnace or a/c, you may be ultra-sensitive to all that dust and fluff now floating around in the air. And if you react strongly to airborne particles, it’s likely you also wake to a stuffy nose if you’ve been sleeping on a typical coil spring mattress for the past few years. You see, the soft padding used in these mattresses is a haven for allergens and in particular, dust mites that absolutely thrive in bedding. Yes, these invisible-to-the-naked eye, eight-legged critters feed off the dead skin cells your body naturally sloughs off during the night and over the years, they multiply and multiply…

Cleaning, airing and vacuuming can help, but at the end of the day you will never fully eradicate dust mites unless you change your approach. And your mattress.

Memory foam mattresses are renowned for their anti-microbial properties and the inability of dust-mites to penetrate their surface. They can be thoroughly spot-cleaned if the need arises, but rest assured that they are totally effective at stopping those mighty-mites in their tracks. Now you may have heard that the chemical process used to produce memory foam can result in some smelly off-gassing that is highly irritating for allergy sufferers. While this can be the case for some brands, many have found a way around this and that’s where Memory Foam Doctor can help. We’ve reviewed many of the top mattress manufacturers and sorted their products by sleep style, price points and special features to produce a comprehensive, consumer-friendly comparison that can help with your purchasing decision.

For those looking for a memory foam mattress that is allergen-free, dust-mite prohibitive and delivers zero to minimal off-gassing, both Helix and Leesa memory foam mattresses are great options. Ready to learn more?



When it comes to on-line mattresses the Helix name may sound new but they’ve actually been around for over 30 years. In fact, this progressive manufacturer was the first to develop and work with 3-D modelling that replicates the human body so their design team can actually see how various body types and sleep styles use the mattress. Constructed entirely in the United States, their mattresses use only the highest quality materials including Helix Dynamic Foam, poly foam, latex and pocketed micro coils for a hybrid mattress that gives you the bounce associated with coil-spring construction but with the comfort of memory foam.

Why is Helix a Great Brand for Allergy Sufferers?

Off-gassing is a common complaint with consumers however because Helix uses high-grade foams that are certified by CertiPUR – US and made without the use of harmful chemicals, there is virtually no off-gassing which makes this mattress ideal for allergy sufferers. On top of that, each of their mattresses is custom-designed for the individual user. You place your order, complete a questionnaire related to your sleep style and preferences, and the Helix team uses this info to begin building your ideal sleep surface. Need a little extra support at the hips and shoulders for tired joints? What about some added cushioning around the tummy or improved ergonomics for that bad back. Helix’s commitment to you is that they will build you a bed that delivers a deeper, more restful sleep that meets your individual needs.



Because of its lightweight construction, the Helix mattress cover delivers enhanced air flow for a cooler, more comfortable sleep. Made from 100% polyester, this fresh, white cover features a softer, brushed top and sturdy, darker blue side panels for a sleeker, customized fit. Better still, a handy zip makes it easy to remove and wash as needed.

Top Layer

Because Helix customizes each memory foam mattress to suit the user’s individual needs, the layering will differ from bed to bed. That said, each of their mattresses does begin with a top layer comprised of 2-inches of high-grade Dunlop latex for a super soft sleep surface that is resistant to dust mites and uses millions of tiny channels to deliver continuous air movement for a cooler sleep.

Second Layer

With Helix, the second layer features 5-inches of individually pocketed spring coils that can move independently to one another for superior support with minimal motion transfer. The benefit to this type of “hybrid” mattress is that it uses both memory foam and micro coils to deliver a sleep surface that provides not only superior support but a little more bounce than standard memory foam mattresses.

Third Layer

The brand’s propriety Helix Dynamic foam forms the third, 2-inch layer of this mattress for an effective transition between the solid foam base and the top memory foam and micro coil comfort layers. This essential layer continues to deliver the superior level of breathability found in the upper layers for an always comfortable sleep experience.

Fourth Layer

The base layer includes 4-inches of high density, allergen resistant poly foam for uniform support of the upper comfort layers and a more durable, longer-wearing mattress.

Additional Benefits


Helix has designed their customer questionnaire around 4 pillars: Elasticity (mattress responsiveness), Support (based on height, weight and typical sleep position), Feel (softer or firmer) and Temperature Regulation (do you prefer a cooler or a cozier sleep) to craft a custom mattress to meet your sleep needs.

Cooler Sleep

Dunlop latex is renowned for it’s cooling properties and being springier than typical memory foam. Because the Helix mattress features a thick, 2-inch top layer of latex, you’re guaranteed a cooler, more comfortable sleep experience.

Trial Period / Warranty

Helix offers a 100-night trial period and the 10-year warranty (with 100% money back guarantee if you are not happy with your purchase within the prescribed timeline).



The design team at Leesa are committed to reimagining your sleep and purchase experience by producing a superior grade memory foam mattress that is manufactured entirely in the United States and foregoes the typical bricks-and-mortar stores for a top-quality product at an affordable price. And because the good folk at Leesa are determined to give back to their communities, they regularly donate mattresses to those in need… which means you can sleep easier knowing you’ve been part of helping those less fortunate. A win-win-win situation!

Why is Leesa a Great Mattress for Allergy Sufferers?

Unlike many of the memory foam mattresses on the market, Leesa does not use ozone-depleting chemicals, heavy metals or contain formaldehyde. As a result, it’s an ideal choice for those suffering from allergies or who are sensitive to chemicals. But there’s more because in addition to staving off those pesky dust-mites and eliminating the problem of off-gassing, this superior grade mattress is renowned for instantly adapting to your body’s contours, taking pressure off key joints and supporting your lower lumbar region regardless of how often you move in the night.



The Leesa mattress cover is a single piece of thinner, lightweight poly-lycra blend fabric that not only tightly secures the entire three layers of memory foam, but ensures you’ll be able to experience the soft, contouring sensation that is synonymous with this style of mattress. And similar to Helix, the cover can be removed for machine washing to ensure an always pristine sleep surface.

Top Layer

The top layer of the Leesa mattress is made from a 2-inch thick layer of their proprietary Avena foam that not only repels dust-mites and allergens but delivers a cooler, more comfortable sleep experience. Like latex, Avena features a softer texture and amazing ability to dissipate body heat however because it is more durable than latex you have a longer-life mattress. Avena foam also offers up a little more “bounce” than regular memory foam so you have a bed that is easier to move around on.

Second Layer

When we move to Leesa’s second layer, we find a 2-inch thick layer of 3-PCF memory foam that delivers deeper compression support and instant contour cradling to distribute your body weight across the entire sleep surface. This takes pressure off key joints such as shoulders, hips and knees for a more restful night and pain-free morning.

Bottom Layer

Leesa’s core support foam base includes 6-inches of high-density foam that is specially designed to support any size of sleeper and help the upper layers to deliver a uniform level of comfort and support. Because this high-density foam is also very breathable, it works in conjunction with the middle and top layers to absorb excess heat and ensure a cooler sleeping surface.


More Bounce

Because Leesa’s proprietary Avena foam delivers a little more “bounce” than conventional memory foam mattresses, you have a bed that is easier to move around on and for fans of coil-spring construction, has that extra springiness you love.

Cool Benefits

Leesa’s Avena foam top layer is not only aerated for enhanced air movement but is made with a breathable foam that allows body heat to dissipate quickly for a cooler, more comfortable sleep.

Trial Period / Warranty

Leesa provides a 100-night trial period and 10-year warranty (with 100% money back guarantee) that is fairly standard with this type of mattress. If you’re unhappy with your mattress at any time during the 100-night period, Leesa will pick it up at no charge to you.
