Comparing Helix & Purple Mattresses

While both of these companies’ mattresses are designed to accommodate a wide variety of sleepers of all shapes and sizes, each comes with their own unique benefits and features.

Deciding Between Helix & Purple 

Firmness / Feel

All mattresses are rated on a firmness scale from 1 to 10, with 1 being the softest and 10 being the most firm. Typically, mattresses on the softer end of the spectrum are better suited for side sleepers because the mattress conforms to their hips and shoulders and allows for proper spinal alignment.

Firmer mattresses support your neck, shoulders, hips, legs, and feet, making them ideal for back or stomach sleepers, especially those with heavier frames. The Purple Mattress, with its memory foam construction, is on the medium-soft side of the firmness scale, allowing it to accommodate side sleepers. The Helix Dusk is on the medium-firm side and allows for stomach and back sleepers to reduce stress on their pressure points. If you’re set on a soft Helix mattress, try the Helix Moonlight. 

Motion Isolation

If you toss and turn while you sleep, or if you tend to get up frequently, you might want to invest in a mattress with low motion transfer, especially if you share your bed with someone else. Motion isolation keeps movement on your side of the bed so it’s less likely that you’ll disturb your partner. The Helix Dusk and the Purple Mattress feature low motion transfer, making them both some of the best mattresses for couples.

Edge Support

Over time, the edges of your mattress may lose some of their firmness, making getting in and out of bed difficult. For the elderly or people with bad backs, having a mattress with edge support is a necessity.

The Helix Dusk’s firm, hybrid construction delivers outstanding edge support, and you won’t have to worry about the mattress losing its edge shape in the years to come. The Purple, while offering some edge support, may lose its shape if you spend a lot of time on the edge of the bed.

Pressure Relief 

A good mattress relieves pressure on your body so that you don’t wake up with aches and pains every morning. In order to provide pressure relief, the Helix Dusk and the Purple incorporate memory foam into their design, allowing them to contour with your body and reduce pressure on areas such as your hips, shoulders, and neck by keeping the spine aligned.

Spine Alignment 

Spinal alignment, like pressure relief, is a necessary quality you should consider when mattress shopping. Keeping your spine aligned is key to promoting proper posture and reducing body aches and pains. The Purple Mattress all-memory-foam construction allows for side sleepers to keep their spines aligned while the Helix Dusk’s hybrid design promotes spinal alignment for back or stomach sleepers. For more mattresses that protect the spine and provide pressure relief, see our picks for the best mattress for back sleepers.


You want a mattress that retains its shape and form for as long as possible. Helix and Purple have designed their products to last a long time, which is why they offer a 10-year warranty on their mattresses. However, the Helix Dusk’s hybrid design and enhanced edge support mean that this mattress will retain its firmness and shape for a slightly longer period.


The Helix Dusk and the Purple Mattress both incorporate various materials into their construction to keep sleepers cool throughout the night. The Purple Mattress has a slight edge because of its proprietary Purple Grid technology found in its comfort layer, which promotes airflow and draws heat away from your body. However, see our list of the best mattress for hot sleepers that features another Helix brand mattress.
