Our Verdict
Nectar Classic
Zinus Original Green Tea 2025
The Zinus Original Green Tea 2025 and the Nectar Classic are both budget all-foam mattresses with a memory foam comfort layer, but they suit different types of sleepers. The Nectar is a softer medium-firm mattress, which makes it a better fit for side sleepers since it allows you to sink in, providing more pressure relief. The Zinus is much firmer, which is better for back and stomach sleepers who need more resistance under the hips to keep the spine aligned. It's also more durable, with higher-density foam. Both mattresses share the classic memory foam trade-offs of low responsiveness and limited bounciness, so neither is a great choice if you move around a lot in your sleep.
