Purple and Helix are two popular online-only companies that bring different things to the table.  Purple has a unique and innovative comfort layer, while Helix has an innovative process that customizes the mattress based on someone’s preferences and characteristics.  I’ll go over the main similarities and differences in this article to help people make a better decision if they are down to Helix vs Purple.

Key Similarities

  • Both have a similar business model / value proposition
  • Both have a similar poly foam base layer
  • Both mattresses are resilient and bouncy

Purple Construction

The picture below gives people an overall sense of the Purple mattress layers.  Here’s a breakdown of all the latyers:

  • The top layer is 2 inches of hyper-elastic polymer.  This material is supportive until it reaches a certain pressure threshold, at which point it collapses.  This means that people get support where they need it and pressure relief where they need it.  I also think it makes the mattress feel firm yet pressure-relieving at the same time.  It’s a highly durable material (more so than foam alternatives) and is completely temperature neutral.
  • The middle layer is 3.5 inches of 1.8 lb. density transition poly foam.  It is meant to provide a smooth transition from the comfort layer to the firm base layer.
  • The base layer is 4 inches of 2.0 lb. density poly foam.

Helix Mattress Construction

The Helix construction will differ depending on the answers to their customization quiz.  The mattress should be 10 inches in total thickness.  The layers will consist of the following materials

  • Helix Dynamic Foam- This is a proprietary foam to Helix.  It has many latex-like qualities.  It is breathable, fairly springy, and has good pressure relief
  • Microcoils- Microcoils help with pressure relief, conforming ability, breathability, and motion transfer
  • Poly foam- There will be a pretty standard poly foam layer and more than likely there will also be a transition layer in the mattress as well

Again, the layers will depend on the answers to the quiz.  The firmness and densities of the foams will vary.

Firmness/Feel Differences

The Purple feels firm yet pressure-relieving at the same time.  That is because when enough pressure is applied to the gel layer, it will collapse.  It will therefore feel firm until the gel collapses, at which point people shouldn’t feel any pressure.  The one caveat here is that if someone doesn’t weigh enough, they might not activate the collapsing of the gel.

The Helix feel will be different depending on the answers to the customization quiz.  It can be extra soft or firm depending on someone’s preferences and characteristics.

Motion Transfer Differences

Both mattresses do pretty well with motion transfer.  I would maybe give Purple the slight edge in this matchup.  That is because the gel is in a grid format where the little pieces of the grid act independently of one another.

Which Should You Pick?

  • If you weigh 125 lbs. or more and sleep just on your side, I think you would do better with the Purple because the pressure relief is so good.
  • If you are really unsure what you want, the Helix might be a great choice because of the customization process
  • If you want something completely temperature neutral, Purple is a great pick
  • If you sleep with a partner with very different preferences, Helix is a great choice


These mattresses do bring very different things to the table.  If you have any specific questions, please leave a comment below.
