Best for Sleep Positions: Eight Sleep

Eight has different comfort models, so it can accommodate side sleepers, back sleepers, and stomach sleepers. The Purple mattress generally only offers one comfort level.



Best for Motion Transfer: Tie for Purple and Eight Sleep

This is a tie-breaker!

Both mattresses do a good job at preventing the sleeper from feeling their partner tossing and turning. Both Eight and Purple offer hybrid mattresses which have additional support for heavier sleepers, but since they have coils in between the layers there will be a slightly extra bounce.

For the best motion isolation, we recommend the Jupiter+ by Eight or the Original mattress by Purple.

Best Trial Period: Purple and Eight Sleep

This is a tie-breaker!

Both mattresses offer a 100 Night Trial. If you don't love your bed, you can return it for free!

Best Warranty: Purple and Eight Sleep

This is a tie-breaker as well!

Both brands offer a 10 Year Warranty. They are confident the quality of their mattresses will hold up over time so you should not to expect to see large indents in your bed.

The Better Business Bureau (BBB) is an organization that has been focusing on consumer trust since 1912. They are a resource where customers can submit their compliments and complaints. We discovered that Eight has as a BBB rating of A+ while Purple has a rating of F.


Both mattresses are a great choice if you are looking for something comfortable that will last. They also both great and minimizing motion transfer. Purple wins the popularity contest, but we believe that Eight wins in innovation, as it is the only bed that can actually tell you how to sleep better. Fast Company even called Eight one of the World's Most Innovative Companies in 2018.
