Helix Midnight vs Helix Midnight Luxe mattress: Materials & design

  • The Midnight Luxe comes with sewn in pillow top 
  • The Midnight is 11.5 inches tall, while the Midnight Luxe is 13.5 inches tall 
  • The Midnight has five layers vs the Midnight Luxe's 6 layers 

The Helix Midnight is 11.5 inches deep and boasts five comfort layers, topped with a breathable cover. The upper layer of Helix's proprietary 'Memory Plus Foam' works to relieve pressure, provide soft sinkage and deep body contouring, while cradling pressure points along your shoulders, hips and lower back. Beneath that are two transitional layers of responsive, high-grade polyfoam. Underpinning it all is a layer of pocketed coils to help minimize motion transfer, followed by a sturdy base layer for stability.

The Helix Midnight Luxe is the newer, taller, plusher version of the original Midnight. It's 13.5 inches tall and is made up of six supportive layers, topped with a plush pillow top for an elevated cloud-like sleep feel and wrapped in a cool to the touch Tencel cover. 

Despite the inclusion of a pillow top, a responsive layer of dense foam prevents you from sinking deeply into this bed. Then, a layer of copper gel-infused ultra responsive memory foam provides additional support and stability. Next up, the layer of durable steel coils (of which there are up to 1,000) provides advanced lumbar support as well as bolstering the sturdiness of the bed's edge. Again,  a dense layer of foam provides the base support of the mattress.

Helix Midnight vs Helix Midnight Luxe mattress: Comfort & support

  • We gave the Midnight a rating of 6.5/10, and the Luxe 6/10 for firmness 
  • Both offer pressure relief for side sleeping, but suits back sleepers too
  • The Luxe offers sturdier edge support 

During our Helix Midnight mattress review, our lead tester rated this bed as a 6.5 out of 10 for firmness (slightly firmer than Helix's rating of 5-6 out of 10), which places it in the medium-firm category. It provides enough cushioning support for side sleepers to gain the pressure relief across the touch points of the mattress, including the shoulders, hips and knees, but also supportive enough for back sleepers, too. 

Motion isolation is strong (which is great news for restless sleepers who share a bed) but we found edge support to be average (a sturdy edge is crucial for those with mobility issues or those who need to sleep right up to the edge).

During our Helix Midnight Luxe mattress review, our lead tester found that the inclusion of the plush pillow top created a sumptuous sleep surface that offered deep pressure relief for side sleepers. However, this bed is supportive enough for back sleepers too. This is largely due to the enhanced lumbar support that works in tandem with the responsive layer of dense foam to hold you on top of the mattress, as opposed to sinking too deeply within it.  

Like the original Midnight, motion isolation is excellent. However, unlike the Midnight, the edge support is reliable on the Luxe. Here, full perimeter support is provided for enhanced stability, which means you won't feel the mattress sink or collapse beneath you when you sit or sleep on its edges. Again, Helix rate this bed as 5-6 out of 10 for firmness, but we think it's a touch firmer at 6 out of 10. Although it's supportive enough for back sleepers, it won't be firm enough for stomach sleepers.

Helix Midnight vs Helix Midnight Luxe mattress: Temperature control

  • Both handle temperature regulation well 
  • Inclusion of more innersprings and Tencel cover boosts the Luxe's temp control
  • Option to upgrade both beds to include a GlacioTex cooling cover

The Helix Midnight handles temperature regulation well, thanks to its breathable cover and the inclusion of individually pocketed coils that help prevent warm air created by body heat becoming trapped within the bed. However, if you sleep particularly hot, you may want to consider upgrading to the GlacioTex cooling cover.

There is also the option to upgrade to the GlacioTex cooling cover, too - but you may not need it. The Luxe comes with a naturally cooling Tencel cover that feels cool to the touch. Beneath, the copper infused memory foam helps keep temperatures regulated, while the additional pocketed coils boost the bed's overall breathability.

Buy the Helix Midnight if...
