Sweetnight CoolNest vs Bear Original: Which Foam Mattress Wins?

Two all-foam mattresses aimed at hot sleepers and value shoppers, the SweetNight CoolNest Memory Foam Mattress and the Bear Original, land in a similar price territory but take different routes to comfort. CoolNest builds its identity around a layered cooling system with a CoolNest cover and PCMflux high-resilience foam, offered in three thicknesses. Bear Original answers with a Celliant Infrared cover, cooling gel swirl memory foam, and a medium-firm feel rated 6.5 to 7 out of 10. Both are all-foam builds, both target everyday comfort, and both back the purchase with a trial period and warranty. Look elsewhere if you want coils; the Saatva Classic is the innerspring alternative. This comparison walks through feel, materials, cooling, value, and policies so you can decide which one fits your sleep.

Which mattress should you choose between CoolNest and Bear Original?

The SweetNight CoolNest Memory Foam Mattress is the better fit for sleepers who prioritize a dedicated cooling system and want to choose between three thicknesses. The Bear Original suits shoppers who want a straightforward medium-firm all-foam mattress with a Celliant Infrared cover and a 365-night sleep trial. Both are all-foam builds, so neither introduces coils into the feel. Your choice comes down to how much you value adjustable thickness and a layered cooling design against a fixed medium-firm feel and a longer trial window.

Who is each mattress for?

The CoolNest is built for hot sleepers who want cooling engineered into more than one layer. SweetNight describes the CoolNest System as feeling up to 8 degrees cooler, pairing a CoolNest cover with PCMflux high-resilience foam. It also offers three thickness options: 12 inch, 14 inch, and 16 inch, so you can match the mattress to how much cushioning you want. The all-foam feel is described as body-cradling support and pressure relief, positioned for side sleepers who need pressure-point contouring.

The Bear Original targets value seekers and anyone who needs stable support and relief for everyday aches and pains. Its feel is rated 6.5 to 7 out of 10, a medium-firm profile described as ideal for most back and side sleepers. The comfort system combines cooling gel swirl memory foam with a high-density foundation foam base, and the cover uses Celliant Infrared fibers. Bear positions the mattress around overnight recovery and consistent support rather than a choice of firmness levels.

Sweetnight CoolNest vs Bear Original: specifications side by side

How do the two mattresses feel and support you?

CoolNest leads with a 5-zone ergonomic support design using nine comfort bars, described as full-body pressure relief across the sleep surface. SweetNight frames the all-foam feel as body-cradling support and pressure relief, which pairs naturally with its positioning for side sleepers who need contouring at the hips and shoulders.

The Bear Original gives you a firmer reference point: 6.5 to 7 out of 10, medium-firm. Bear describes quilt foam and memory foam comfort layers that gently hug your curves while a high-density foam foundation reinforces the bed, so you never feel unstable. That combination is aimed at proper spinal alignment and resistance to sagging over time. If you prefer a defined medium-firm feel and want that number stated up front, Bear makes the clearer promise on feel.

Which mattress handles heat better for hot sleepers?

Cooling is the axis where these two mattresses state their case most clearly, and each takes a different approach. SweetNight builds the CoolNest System as a layered solution: the CoolNest cover and PCMflux high-resilience foam work together for all-night cooling, supported by a 3D airflow structure design in the cover. SweetNight states the system feels up to 8 degrees cooler. The three thickness options also change how much material sits between you and the support core, which matters if you sleep very hot and want a specific configuration.

Bear approaches temperature through its materials rather than a named cooling system. Cooling gel swirl memory foam sits in the comfort layer, and the cover fabric uses Celliant Infrared fibers. If a named, multi-component cooling system with a stated temperature claim matters to you, CoolNest makes the more specific case. If you prefer gel-infused foam paired with an infrared cover, Bear covers that ground. For a wider look at cooling options, see our best cooling mattresses for 2026.

How do materials and certifications compare?

Both mattresses use CertiPUR-US certified foam, so the foam itself meets the same certification standard on each side. SweetNight adds that the CoolNest fabric passes the STANDARD 100 by OEKO-TEX test. The CoolNest layer list includes a 3D weaving CoolNest cover, PCMflux high-resilience foam, gel-infused memory foam, ocean memory foam, transition comfort foam, and 5-zone support foam with nine comfort bars.

Bear layers on additional certifications: GREENGUARD Gold certified and fiberglass free, assembled in the USA with foreign and domestic components. Its comfort stack pairs cooling gel swirl memory foam with high-density foundation foam, and the cover carries the Celliant Infrared fibers. Shoppers who weigh certifications heavily will notice Bear carries GREENGUARD Gold alongside CertiPUR-US, while SweetNight pairs CertiPUR-US with OEKO-TEX fabric certification. Neither mattress introduces coils, so both remain pure foam builds in feel and construction.

What do trial, warranty, and shipping look like?

This is where the two products separate most sharply. The Bear Original carries a 365-night sleep trial, free shipping and free returns, and a limited lifetime warranty, with fast free shipping that ships within 5 to 8 business days. The SweetNight CoolNest offers a 100-night trial, a 10-year warranty, and free U.S. shipping. Bear also offers a selectable in-home setup and removal option at checkout, while SweetNight lists fast and free shipping with secure payment methods.

For buyers who want a full year to decide and long-term warranty coverage, Bear’s terms are the stronger published promise. For buyers who value a shorter trial with a 10-year warranty and free shipping, CoolNest covers the basics. Neither mattress’s trial or warranty terms should be treated as interchangeable, so weigh how much time you realistically need to evaluate a new mattress.

Which mattress offers better value?

On published pricing, the SweetNight CoolNest lists a queen at $349.99. Value for the CoolNest is easy to see on paper: a queen-size all-foam mattress with a layered cooling system at that list price, backed by a 100-night trial and 10-year warranty.

Bear’s value case rests on what is included rather than a stated figure: a 365-night trial, limited lifetime warranty, free shipping and returns, GREENGUARD Gold and CertiPUR-US certifications, and a Celliant Infrared cover.

If you are open to coils, our best hybrid mattresses for 2026 covers that category.

Who should pick which mattress?

Pick the SweetNight CoolNest if you sleep hot and want a named cooling system with a stated temperature claim, you want to choose among 12, 14, and 16 inch thicknesses, you are primarily a side sleeper drawn to body-cradling pressure relief, and you want a queen-size all-foam mattress at a published list price of $349.99 with a 100-night trial and 10-year warranty.

Pick the Bear Original if you want a clearly stated medium-firm feel at 6.5 to 7 out of 10, you value a 365-night sleep trial and a limited lifetime warranty, you want free shipping and free returns with a selectable in-home setup option, and you prefer a mattress certified GREENGUARD Gold and CertiPUR-US with a fiberglass free build and a Celliant Infrared cover.

Neither mattress introduces coils, so if you want spring support rather than foam, both of these sit outside your search. The Bear Original does offer an Original Hybrid upgrade with individually encased coils for shoppers who like the Bear brand but want coil support.

What is the verdict of this comparison?

The Bear Original wins this face-to-face comparison. It states a clear medium-firm feel at 6.5 to 7 out of 10, backs it with a 365-night sleep trial and a limited lifetime warranty, and layers certifications including GREENGUARD Gold and CertiPUR-US on a fiberglass free build. The SweetNight CoolNest makes a credible case for hot sleepers with its CoolNest System, three thickness options, and a published queen price of $349.99, but its 100-night trial and 10-year warranty are shorter commitments than Bear’s published terms. Choose CoolNest if adjustable thickness and a dedicated cooling system are your priorities; choose Bear if you want the longer trial, lifetime warranty, and a stated firmness number.

World Sleep Almanac score

World Sleep Almanac score: 7.6/10 for the Bear Original, the winner of this comparison. The score is an editorial rating based on five criteria: price at equal size, trial and returns, warranty, materials and construction, and public customer reviews. Bear scores well on trial and warranty with 365 nights and a limited lifetime warranty, and on materials with GREENGUARD Gold, CertiPUR-US, and a fiberglass free build. The SweetNight CoolNest earns a 7.2/10 on the same criteria, held back by its shorter 100-night trial and 10-year warranty despite a published queen price and a layered cooling system.

Frequently asked questions

Is the SweetNight CoolNest cooler than the Bear Original?

SweetNight states its CoolNest System feels up to 8 degrees cooler, using a CoolNest cover and PCMflux high-resilience foam together with a 3D airflow structure. Bear uses cooling gel swirl memory foam and a Celliant Infrared cover. Each brand describes its own approach, and no direct head-to-head cooling test between the two is published here.

Can I choose the firmness of either mattress?

Neither mattress offers multiple firmness options. The Bear Original is available in one feel, medium-firm at 6.5 to 7 out of 10.

Which mattress has a longer trial period?

The Bear Original offers a 365-night sleep trial, while the SweetNight CoolNest offers a 100-night trial. Bear also includes free shipping and free returns, and lists a selectable in-home setup and removal option at checkout.

Do both mattresses contain fiberglass?

Bear states the Bear Original is fiberglass free. The available SweetNight product information does not address fiberglass for the CoolNest, so no claim can be made either way on that point.

Which mattress is better for side sleepers?

SweetNight positions the CoolNest’s all-foam feel for side sleepers who need pressure-point contouring, supported by its 5-zone ergonomic support design. Bear describes its medium-firm feel as ideal for most back and side sleepers. Both name side sleepers as a fit, so the decision comes down to whether you prefer the CoolNest’s contouring description or Bear’s stated 6.5 to 7 out of 10 feel.
