Zinus 8" Green Tea Memory Foam Mattress, Short Queen (OLB-GTFM-8SQ)

2026 lineup note: The Green Tea 8" Short Queen (model OLB-GTFM-8SQ, ASIN B072M8JWGQ, UPC 841550211351) remains an active Zinus SKU in 2026. Zinus has since added newer variants — a "Cooling Gel" Green Tea 8" Short Queen (ASIN B0CKYYDDVM, 60"×74") and the "Ultima" RV line (e.g., SC-BTCM-8SQ) — but the original OLB-GTFM-8SQ is still sold and is the price benchmark of the category. Verify the ASIN/model at checkout: the name "8 Inch Green Tea" is shared across variants.

Version lineage (2023–2026)

• OLB-GTFM-8SQ (original, current): The long-running 8" Green Tea memory foam mattress in Short Queen 60"×74". Construction: green tea + charcoal-infused memory foam comfort layers over high-density base foam ("custom contour support"). Fiberglass-free, CertiPUR-US certified foams. Amazon list $269; the SKU has been sold since ~2017.
• Cooling Gel variant (newer): "8 Inch Green Tea Cooling Gel Memory Foam Mattress, RV/Camper/Trailer, Short Queen 60"×74"" (ASIN B0CKYYDDVM) — adds cooling-gel infusion, marketed as Zinus's "most cooling formula." Amazon's Choice, 100+ bought in past month (amazon.ca listing, 2026).
• Ultima line (newer): "8 Inch Ultima Memory Foam Mattress [New Version], Short Queen" (model SC-BTCM-8SQ) — 7-zone comfort system, green tea + charcoal, fiberglass-free, OEKO-TEX cover; positioned a tier up (~$245 street).
• Hybrid variant: An 8" Green Tea foam + coil-spring hybrid Short Queen also exists (UPC 841550211399) — different feel (firmer), don't confuse with the all-foam.
• Smart-buy advice: The original OLB-GTFM-8SQ is usually the cheapest way into a real mattress for an RV queen bunk and the most-reviewed. Pick the Cooling Gel variant if you sleep hot; the Ultima if you want zoned support. All are 60"×74" Short Queen unless stated otherwise — measure your bunk (some "queen" RV bunks are 60"×80" or odd sizes).

Overview

The go-to budget RV mattress: 8" of CertiPUR-US certified memory foam infused with green tea extract and charcoal (odor control/freshness), medium-firm feel, shipped compressed in a box. Short Queen 60"×74" fits standard RV queen bunks.

Community Verdict

The Green Tea Short Queen is the most-recommended budget RV mattress across RV and van-life communities — the recurring verdict is that it's dramatically better than the thin stock "mattress" most trailers ship with, at a price ($200–$250 street) that makes it a near-automatic upgrade. Amazon's Choice status with 100+ bought in the past month (2026) reflects sustained demand. The honest caveats from owner discussion: it's medium-firm (side sleepers often add a topper — which is exactly why the Lucid 3" topper pairs with it in so many RV setups), and like all memory foam it can sleep warm, which is why Zinus now sells the Cooling Gel variant.

Additional voices (Sept 2026 research): sleepbehind.com's Sept 2026 8"-vs-12" comparison is the most useful durability frame - they expect the 8" to hold up 5-6 years of regular use with rotation every 3-6 months, with Zinus's 10-year warranty covering sagging beyond 1 inch, and advise a washable protector plus a topper to extend foam life. RTINGS' 2025 review of the refreshed "Original Green Tea 2025" calls it firmer than rivals with higher-density foam that "should resist sagging for longer" - a point in its favor against cheaper foam competitors. The outliers: a 2021 Amazon review mirror (via shopabunda) of a unit that never expanded past 6" (refunded, told to discard), and a 230-lb reviewer whose 8" developed a permanent middle sag in two nights - above the "average-weight" use case the 8" is built for, but a real data point for heavier sleepers considering this thickness.

Long-term durability & warranty-claim reality

The 8" Green Tea is a 5-6-year mattress in regular RV/seasonal service (sleepbehind.com, Sept 2026) with rotation every 3-6 months; the 10-year warranty covers sagging beyond 1 inch, which is the realistic failure definition. Owner reality: average-weight back/stomach sleepers get the full lifespan; the failure reports come from the edges of the use case — a 230-lb reviewer developed a permanent middle sag in two nights (2021 review mirror), and side sleepers over ~220 lbs report limited deep contouring. RTINGS' 2025 review of the refreshed Original Green Tea 2025 credits higher-density foam that "should resist sagging for longer" than cheaper competitors. Heat retention is the persistent comfort complaint (memory foam sleeps warm — the reason for the Cooling Gel variant), and edge support is weak (sit on the edge and you sink). The expansion-failure outlier (a unit stuck at 6" instead of 8", refunded in 2021) is the warranty-claim archetype — Zinus refunded and told the owner to discard, which tells you the claim process is painless but the remedy is replacement, not repair.

Version history — year by year

• 2023: OLB-GTFM-8SQ (ASIN B072M8JWGQ) the long-running original, sold since ~2017; Amazon list $269.
• 2024: Cooling Gel variant added — "8 Inch Green Tea Cooling Gel Memory Foam Mattress, RV/Camper/Trailer, Short Queen" (ASIN B0CKYYDDVM), Amazon's Choice with 100+ bought/month.
• 2025: Ultima line added — "8 Inch Ultima Memory Foam Mattress [New Version], Short Queen" (SC-BTCM-8SQ), 7-zone comfort, OEKO-TEX cover, ~$245 street; RTINGS reviews the refreshed "Original Green Tea 2025" naming. Foam+coil hybrid Short Queen (UPC 841550211399) also in the line.
• 2026: Original OLB-GTFM-8SQ still sold and still the price benchmark; street ~$249 (April 2026 camelcamelcamel; fresh Sept 2026 US price UNVERIFIED).

Head-to-head vs closest rivals

• vs LUCID 3" gel topper (existing catalog): the pairing question, not a rivalry. Zinus alone = medium-firm, budget, 5-6-year mattress; Zinus + Lucid 3" = the ~$300-350 RV sleep system that dominates forum recommendations. Add the topper if you're a side sleeper or the Zinus feels too firm; skip it if you sleep hot or need firm support (the topper softens and warms the feel).
• Within the Zinus family (documented in this file): original Green Tea 8" (cheapest, most-reviewed) vs Cooling Gel (hot sleepers) vs Ultima 8" (zoned support, a tier up, ~$245) vs the hybrid (firmer, coil feel). Verify the ASIN/model at checkout — "8 Inch Green Tea" is shared across variants.
• Outside the catalog: no other RV mattress currently has its own file here; the general market alternative is a residential bed-in-a-box cut to size (usually worse value once you pay for custom sizing).

Care & maintenance

Let it expand 24-72 hours in a ventilated room-temperature space before judging firmness. Rotate 180 degrees every 3-6 months to prevent uneven wear (sleepbehind.com). Use a washable waterproof mattress protector — sweat and spills degrade foam. Ensure the bunk platform supports it: closely spaced slats or a solid bunk (wide slat gaps let foam sag between them — general memory-foam guidance, Zinus-specific bunk spec UNVERIFIED). A topper on top extends the mattress's own life by taking the surface wear. Don't fold or bend it for storage; don't jump on it.

Buying traps

• Variant confusion is the #1 trap: OLB-GTFM-8SQ / B072M8JWGQ (original) vs B0CKYYDDVM (Cooling Gel) vs SC-BTCM-8SQ (Ultima) vs UPC 841550211399 (hybrid) — all called "8 Inch Green Tea" in listings. Verify the model/ASIN in your cart.
• Expansion failures: if it doesn't reach ~8" within a week, that's a warranty/return event, not patience — the 2021 stuck-at-6" case was refunded outright.
• Stale street prices: the $248.80 figure is from April 2026 (camelcamelcamel) — re-verify live; Zinus pricing moves with Amazon promotions.
• Amazon commingled inventory: buy from the Zinus store or a reputable seller to avoid variant mix-ups; check the law tag/model on arrival.
• Weight limit: 500 lbs for the short queen (250 lbs twin) — heavier couples should consider the 10"/12" or a hybrid.
