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.

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.
