A 12-inch all-foam bed with Zinus's zoned pressure-relief foam, infused with green tea extract and charcoal for odor, over a durable base foam, with a knitted cover. Zinus labels it medium firm and prints 7–8 out of 10, which most people would call firm. Foams are CertiPUR-US certified, the cover OEKO-TEX, and the listing says it is fiberglass-free. Sold by Amazon.com; 500 lb listed limit; 10-year limited warranty.
How the Zinus Green Tea 12 in handles back pain
At 7–8, it is firm enough to keep the hips up for back and stomach sleepers. The zoned foam gives a little extra at the shoulder. For a cheap test of whether firmer support helps your back, it is hard to beat.
Who should skip the Zinus Green Tea 12 in
- Side sleepers with shoulder pain: 7–8 is firm for a side sleeper.
- Heavier sleepers: budget foam compresses faster under more weight; consider a hybrid.
- Hot sleepers.
What the Zinus Green Tea 12 in listing leaves out

Zinus Green Tea 12 in: what readers ask
Is the Zinus Green Tea mattress firm?
