Zinus Original Green Tea Memory Foam (10-inch)

Sources & review notes

• Exact model — Original Green Tea Memory Foam Mattress, 10-inch, sold on zinus.com. Checked 2026-09-20. This is the only non-cooling Green Tea height Zinus sells on its own site on the checked date. It is not the Amazon-only 12-inch "[New Version]" Green Tea (model ZU-MFMA1ZZI-12Q), not the 12-inch Cooling or Ultra Cooling Green Tea, not the Green Tea Hybrid, and not the discontinued 6-, 8-, 12-, and 14-inch heights that older reviews describe. Results here apply to the 10-inch Original only.
• Type — All-foam memory foam, three layers. Checked 2026-09-20. Zinus lists the core as 2.5 inches of green tea memory foam, 2 inches of Z:Comfort foam, and 5.5 inches of Z:Base foam under a knitted poly jacquard cover. One feature bullet on the same page says "1.5 inches of Green Tea memory foam," which contradicts the core-composition spec; the spec figure is used here and the discrepancy is disclosed. Foams are CertiPUR-US certified and Zinus states the mattress is fiberglass free.
• Firmness — Zinus says medium-firm (6.5/10); measured firm. Checked 2026-09-20. The manufacturer label is "medium-firm feel" at 6.5 on its own 10-point scale. RTINGS measured a normalized stiffness of 69 Pa/mm on the 2025 version of this exact 10-inch model and classifies that as firm, noting it feels firmer than the label suggests. Older reviews that call the Green Tea "medium" or "medium soft" tested different heights or an earlier build.
• Height — 10 inches. Checked 2026-09-20. Published as 10 inches in every size, with a stated tolerance of plus or minus half an inch. The queen weighs 53.9 lb, which is light for a queen and consistent with modest foam densities.
• Price — Check current price — $359 queen clearance, $718 "original". Checked 2026-09-20. Zinus showed a clearance price of $359 against an original price of $718 for the queen on the checked date. The struck figure should not be read as a price anyone recently paid; treat the clearance figure as the effective price and expect it to move. Prices for other sizes were not verified.
• Trial — 100 nights from delivery, zinus.com purchases only. Checked 2026-09-20. Zinus states the trial applies to US customers who bought on zinus.com. Mattresses bought through Amazon or other retailers follow that retailer's return terms instead. Zinus publishes no minimum break-in period.
• Delivery — Free compressed-box shipping, 3–7 business days. Checked 2026-09-20. Ships to the 48 contiguous states and the District of Columbia after about one business day of processing; Zinus does not ship to Alaska, Hawaii, or US territories. A state recycling fee may apply in CA, CT, RI, and OR. Allow the foam time to expand before judging the feel.
• Returns — Refund during the trial if returned in good condition. Checked 2026-09-20. Zinus requires the mattress to be in good condition — its wording is "no drool, stains or mysterious smells" — with documents and proof of purchase. The product page does not state whether Zinus collects the mattress or charges a return fee, so confirm the process with Zinus before relying on it. A mattress protector is a practical precaution given the condition requirement.
• Warranty — 10-year limited warranty. Checked 2026-09-20. Zinus calls it the "Zinus handshake" and covers faults in materials and manufacturing defects for mattresses bought new from an authorized retailer. The written terms exclude foam deterioration producing an indentation of less than 1.5 inches, allow Zinus to choose between replacement and a prorated refund, require a proper foundation, and are voided by stains, removed law tags, or use of a heating pad or electric blanket. Read the written warranty before relying on it.
• Firmness — Firm — 69 Pa/mm normalized stiffness. Measured data. RTINGS measured 65 Pa/mm at the head and feet and 69 Pa/mm at the lumbar zone and classifies the result as firm. That is firmer than the "medium-firm 6.5" Zinus labels it, and much firmer than the medium-soft feel older reviews assigned to the discontinued 12- and 14-inch heights. The soft memory-foam top is thin enough that most sleepers press through it into the firmer polyfoam beneath.
• Pressure relief — 6.1 / 10 — indent 1.2 in at 110 lb, 1.9 in at 176 lb, 2.6 in at 242 lb. Measured data. Mediocre overall and strongly weight-dependent. Lighter and average-weight sleepers do not sink far enough for the surface to spread load at the shoulder and hip; heavier sleepers compress the foam enough to get genuine cushioning. This is the opposite of the pattern on plush all-foam beds and the main reason the side-sleeper fit calls below are cautious.
• Cooling — 7.5 / 10 — 60 kJ transferred in the first hour, 154 kJ over 8 hours. Measured data. Good for an all-foam bed, helped by the firm surface: you lie on the foam rather than in it, so less of your body is enclosed. RTINGS notes it will not feel cool on first contact and that very hot sleepers may want a bed that dissipates heat faster. Green tea and charcoal infusions are odor treatments, not cooling technologies.
• Motion isolation — 8.2 / 10 — 4.33 g peak acceleration at the lumbar, dissipating in 0.29 s. Measured data. The strongest measured attribute and the clearest reason to buy this over a budget innerspring. Movement stays close to its source and there is no lingering bounce, which matters for couples with different schedules.
• Response / bounce — 5.7 / 10 responsiveness rating. Measured data. The lowest category score. The memory-foam top holds an impression briefly before recovering, so changing position takes more effort than on a coil or latex bed. RTINGS does not publish a recovery time for this model, so no timing figure is presented.
• Edge support — 6.4 / 10 edge-support rating. Measured data. Below average. There is no reinforced perimeter — the base foam simply runs to the edge — and RTINGS reports that the edge compresses noticeably and forms a slope when you sit or lie near it. No sinkage depth is published for this version, so none is shown.
