The Nolah and Helix comparison puts two of the DTC segment's most interesting brands head to head. Nolah built its reputation on proprietary AirFoam technology designed specifically for side sleepers. Helix built theirs on customization — offering more distinct models than almost any other mattress brand.
The AirFoam Claim: What Is It?
Nolah's AirFoam is a proprietary open-cell foam formulation that Nolah claims sleeps cooler than standard memory foam and provides superior pressure relief. Independent testing confirms AirFoam sleeps cooler than traditional memory foam, though it's not cooler than a good hybrid with coil airflow.
Pros and Cons
What We Like
- AirFoam provides excellent pressure relief
- Great motion isolation for couples
- Good for side sleepers
- CertiPUR-US certified foams
What Could Be Better
- Not ideal for very heavy sleepers
- Limited edge support vs hybrids
- Only available online
- May sleep warm for some
Helix's Customization Advantage
Helix offers 11 models targeting different body types, sleep positions, and preferences — from Helix Dawn (extra firm) to Helix Moonlight (plush side sleepers), plus Luxe and Elite versions of most models with enhanced materials. Their sleep quiz recommends the best match for your specific profile.

Frequently Asked Questions
Is Nolah or Helix better for side sleepers?
Both perform well for side sleepers. Nolah's AirFoam provides excellent pressure relief with its proprietary foam formula. Helix Midnight (the side-sleeper-targeted model) delivers comparable pressure relief with the added benefits of a hybrid's cooling and responsiveness. For hot side sleepers, Helix Midnight has the edge.
Does Nolah AirFoam sleep hot?
Nolah AirFoam is marketed as sleeping cooler than memory foam, and that claim is largely validated — its open-cell structure dissipates heat better than traditional memory foam. However, it still runs warmer than hybrid constructions with coil airflow. Hot sleepers should consider Nolah's Evolution hybrid instead.
Which brand offers more customization?
Helix wins clearly on customization. They offer 11 mattress models across a firmness spectrum, plus a sleep quiz that recommends the best match. Nolah offers fewer models (Original, Evolution, Natural) with fewer firmness options. For personalization, Helix is the better platform.
How do Nolah and Helix compare on motion isolation?
Nolah Original (all-foam) has excellent motion isolation — better than most hybrids. Helix hybrids are good but not exceptional on motion isolation due to the coil component. For light sleepers disturbed by partner movement, Nolah's all-foam construction has an advantage.
Which has a better trial and warranty?
Both Nolah and Helix offer 120-night trials with free returns. Nolah offers a lifetime warranty; Helix offers a 10-year warranty. Nolah's lifetime warranty is a meaningful long-term advantage.
