Our Verdict

Sleep On Latex Pure Green Organic

Novosbed

The Sleep On Latex Pure Green Organic is a better mattress than the Novosbed for most people. Both models are very firm and best suited to back and stomach sleepers, but the Sleep On Latex offers better support and pressure relief. It's also more responsive and provides better edge support, making it very easy to move around and get in and out of bed. It's a bit more cooling, too, which can make a big difference for hot sleepers, and it's more durable. The Novosbed isolates motion a little more effectively, but the difference shouldn't be enough to sway most people.
