The Zinus Ultra Cooling Gel Memory Foam Mattress is a 12-inch all-foam bed built around one promise: staying cool while you sleep. According to the official specifications, it layers 2.5 inches of premium cooling gel memory foam over a half inch of memory foam, uses a cool-to-the-touch cover, and features what Zinus calls a triple cooling 7 zone comfort system. The brand lists it as fiberglass free, made in the USA, and built from three layers of CertiPUR-US certified foams. This page lays out the documented facts on price, trial, warranty, and construction so you can decide whether it fits your bedroom.

Who should buy the Zinus Ultra Cooling Gel Memory Foam?
The Zinus Ultra Cooling Gel Memory Foam Mattress is aimed at hot sleepers and combination sleepers who want a foam bed with a cooling story. Zinus explicitly lists “Hot Sleepers” and “Combo Sleepers” under the product’s good-mattress-for section, and the brand describes the bed as delivering temperature regulation, pressure relief, and tailored comfort. If you move between positions at night and you wake up warm, this is the buyer profile the product page is written for.
The second buyer is someone furnishing a room on a defined budget who still wants a 12-inch profile rather than a thin starter foam. The official page shows a current price of $699.00 against an original price of $899.00 on the Full size, and lists a clearance sale. Prices and promotions change, so check the current price on the official site before you commit to a size.
The third buyer is anyone who specifically wants a fiberglass-free foam mattress made in the USA. Both of those statements appear on the official product page, alongside the CertiPUR-US certification for the three foam layers. If those labels matter to your purchase decision, the documented facts confirm them for this model.
What does the construction actually include?
The build is straightforward and fully documented: a 12-inch height, 2.5 inches of premium cooling gel memory foam, and a half inch of memory foam, for a total of three high quality CertiPUR-US certified foam layers. The cover is described as cool to the touch, and the comfort system is labeled a triple cooling 7 zone comfort system. That is the complete layer list the brand publishes for this mattress.
The 7 zone designation refers to pressure relief mapped across seven regions of the mattress surface. Zinus presents it as part of the cooling and comfort package rather than as a separate support core. The brand does not publish foam densities, ILD ratings, or a full layer-by-layer diagram on the page reviewed here, so treat the three-layer description as the complete public specification.
Here is how the headline numbers break down:
| Specification | Documented value |
|---|---|
| Height | 12 inches |
| Cooling gel memory foam | 2.5 inches |
| Memory foam layer | 0.5 inches |
| Foam layers | 3 CertiPUR-US certified layers |
| Cover | Cool to the touch |
| Comfort system | Triple cooling 7 zone |
| Fiberglass | Fiberglass free |
| Origin | Made in the USA |
| Trial | 100 nights |
| Warranty | 10 years |
| Shipping | Free shipping |
How does the cooling story hold up on paper?
The cooling claim rests on three documented elements: the gel-infused memory foam, the cool-to-the-touch cover, and the enhanced airflow the brand associates with the comfort system. Zinus states the mattress delivers optimal temperature regulation for hot sleepers. Those are the brand’s own words on the official product page, and they are the basis for the cooling positioning.
What the official page does not publish is a measured temperature figure, a thermal test result, or any independent verification of the airflow claim. The documented facts show a materials story, not a laboratory outcome. Read the cooling language as a description of what is in the mattress, and check current customer feedback on the official site for real-world temperature reports before you buy.
For buyers, the practical check is simple: confirm the cover material and the gel layer on the live product page, since Zinus sells several Green Tea variants at different heights and with different cooling features. The Ultra Cooling is its own 12-inch listing, and you should verify that the size and upgrade you select still show the 2.5-inch gel layer and cool-to-the-touch cover at checkout.
What do the trial, warranty, and shipping terms cover?
The official product page lists a 100 night trial, a 10-year warranty, free shipping, and Made in USA production. Those four terms appear together in the product badges on the Zinus listing reviewed here. They are the complete service terms the brand publishes for this mattress.
The 100 night trial is the window in which you can evaluate the mattress at home. The 10-year warranty is the coverage period the brand states for the product. Neither the trial conditions nor the warranty exclusions are detailed on the page reviewed, so read the full trial and warranty documents on the official site before ordering, and confirm what happens if you decide to return the mattress inside the 100 night window.
Shipping is listed as free, with no white-glove setup or old mattress removal mentioned in the official specifications for this model. If in-room delivery and setup matter to you, that is a gap you should confirm directly with Zinus at checkout rather than assume.

What does the Zinus Ultra Cooling Gel cost by size?
The official page shows a current price of $699.00 against an original price of $899.00 on the Full size, a 22 percent saving. The same listing shows Queen at $529.00 against $999.00, a 47 percent saving, and King at $999.00 against $1,199.00, a 16 percent saving. The Full, Queen, and King rows all carry a sold out marker on the page reviewed here, so availability at these prices must be confirmed on the live site.
Pricing and stock move frequently on clearance listings, and the page also shows a low inventory and out of stock state for some configurations. Check the current price on the official site for your exact size before you plan around any figure on this page. The table below records what the official listing displayed at the time of review.
| Size | Current price | Original price | Saving |
|---|---|---|---|
| Full | $699.00 | $899.00 | 22 percent |
| Queen | $529.00 | $999.00 | 47 percent |
| King | $999.00 | $1,199.00 | 16 percent |
The listing also references monthly payments with Affirm, and the site notes that shipping and taxes are calculated at checkout. Neither the financing terms nor the tax-inclusive total is fixed on the product page, so confirm the final amount in your cart.
How does it feel and support you while you sleep?
Zinus describes the mattress as delivering pressure relief and tailored comfort for hot, combo sleepers, with the 7 zone system handling relief across the surface. The brand does not publish a firmness number, a firmness scale, or a sleeper-weight recommendation for this model on the page reviewed. That means the feel has to be judged from the layer description alone: a 2.5-inch gel memory foam comfort layer over a half inch of memory foam, on a 12-inch profile.
For buyers, the practical step is to read current owner feedback on the official product page for comments about firmness and sinkage, since no official firmness rating is published. If you have a specific support need, such as a documented back condition or a body weight above the range you usually shop for, confirm the suitability directly with Zinus before ordering rather than infer it from the layer list.
What about motion isolation, edge support, and noise?
The official product page does not publish test results, ratings, or descriptions for motion isolation, edge support, or noise on this model. These are three areas where the documented facts are silent, so no performance claim can be made from the sources reviewed here.
What you should do is check the current customer reviews on the official Zinus listing for comments on these three points, and confirm with Zinus whether any edge or motion guidance exists in the product documentation. For couples, motion isolation is usually the first of the three to matter, and for anyone who sits on the edge to put on shoes, edge support is the one to verify.
Who should NOT buy the Zinus Ultra Cooling Gel Memory Foam?
Skip this mattress if you need a longer trial than 100 nights, want in-room delivery and setup, or require a warranty period longer than the 10 years Zinus lists. Those three terms are fixed in the official specifications, and none of them can be extended on the product page reviewed here. If any of them is a hard requirement, this is not the right buy.
Also skip it if you need a firmness rating or a sleeper-weight recommendation before you purchase. The official page does not publish either for this model, so there is no documented basis for confirming the feel matches your body and sleep position. In that case, confirm the details with Zinus directly, or look at a listing that publishes a firmness figure.
Finally, skip it if the sizes you need are showing sold out. The Full, Queen, and King rows on the page reviewed all carried a sold out marker alongside their clearance prices, and stock states change quickly. Verify availability at checkout before you build a purchase plan around this mattress.
How does the Saatva Classic compare on trial and delivery?
The Saatva Classic is the Saatva alternative to consider if the Zinus trial and delivery terms fall short of what you need. According to the official Saatva specifications, the Saatva Classic carries a 365-night home trial, free white-glove delivery with setup, and a lifetime warranty. It is an innerspring mattress with a 3-inch Euro pillow top, a dual-coil design of over 1,000 recycled carbon steel coils in full size and up, and three comfort levels: Plush Soft at 3 out of 10, Luxury Firm at 5 to 7 out of 10, and Firm at 8 out of 10.
Saatva also lists Lumbar Zone Technology for spinal alignment, an organic cotton cover treated with Guardin botanical antimicrobial treatment, CertiPUR-US certified foams, GREENGUARD Gold certification, and endorsement by the American Chiropractic Association. The Saatva Classic page shows two height options, 11.5 inches and 14.5 inches, and a current displayed price of $1,904 against an original $2,229 on the configuration shown. Prices and promotions change, so check the current price on the official site.
The trade-off is price. The Zinus Ultra Cooling lists at $529.00 for Queen in the clearance display, while the Saatva Classic configuration shown lists at $1,904. If your priority is the lowest upfront cost for a 12-inch cooling foam bed, the Zinus is the documented budget option. If your priority is a 365-night trial, white-glove setup, and a lifetime warranty, the Saatva Classic is the documented match.
Verdict
The Zinus Ultra Cooling Gel Memory Foam is a reasonable budget pick for hot and combination sleepers who want a 12-inch fiberglass-free foam bed with a 100 night trial and a 10-year warranty. Buy it if a low clearance price and a cooling materials story are what you want, and check the current price and stock on the official site first. Choose the Saatva Classic instead if you want a 365-night trial, free delivery and setup, a lifetime warranty, and three firmness options on an innerspring build.
World Sleep Almanac score: 7.2/10
The World Sleep Almanac editorial score is an editorial rating based on five criteria, each assessed against the documented facts on the official product pages: price at equal size, trial and returns, warranty, materials and construction, and public customer reviews. The method is stated in one sentence so the number can be read alongside its reasoning, and a full methodology page will be published when it goes live.
- Price at equal size: 8/10.
- Trial and returns: 6/10. The 100 night trial is documented and real, but it is shorter than the 365-night trial Saatva lists for the Saatva Classic, and the return conditions are not detailed on the page reviewed.
- Warranty: 6/10. The 10-year warranty is clearly stated, but the Saatva Classic lists a lifetime warranty, and Zinus does not publish warranty exclusions on the product page reviewed.
- Materials and construction: 8/10. Three CertiPUR-US certified foam layers, 2.5 inches of cooling gel memory foam, a cool-to-the-touch cover, fiberglass free construction, and Made in USA production are all explicitly documented.
- Public customer reviews: 7/10. The official listing carries a live review section, and buyers should read current feedback there for firmness and temperature reports, since the brand publishes no firmness rating or temperature figure for this model.
The score reflects the documented strengths on price and materials against the documented limits on trial length and unpublished firmness data. It is an editorial judgment, not a test result.
