Our Verdict
Zinus Original Green Tea
Novaform ComfortGrande Plus
The Novaform ComfortGrande Plus is better than the Zinus Original Green Tea. The Novaform is a budget-friendly all-foam mattress with much better cooling. It's also more responsive, so you're less likely to feel stuck in place, and it has even better motion isolation, allowing you to feel your partner's movements less noticeably. The Novaform also offers better edge support, which makes it easier to get in and out of bed. The Zinus is a cheaper option, so you might prefer it for that reason.
